Chelsea\u2019s engineering prowess in PTO design was well respected \u2013 Muncie\u2019s early PTO business was actually built by selling Chelsea units wholesale. Chelsea was eventually acquired by Parker Hannifin, becoming the <strong>Chelsea Products Division<\/strong> of Parker, and today leverages Parker\u2019s global manufacturing might. Parker Chelsea PTOs have a strong presence worldwide in vocational, fire\/rescue, oilfield and heavy-haul markets.<br>    <\/li>\n\n\n\n<li><strong>Bezares S.A. (Spain)<\/strong> \u2013 Established in 1954 in Madrid by Jos\u00e9 Bezares, Bezares grew from a small truck repair workshop into a global hydraulic and PTO manufacturer. Over seven decades, Bezares expanded internationally and now serves over 100 countries with multiple manufacturing plants. Bezares is known for rugged PTO designs built with premium materials to handle harsh conditions. They produce PTO models compatible with all major transmission brands (Allison, Eaton, ZF, Volvo, etc.) and have pioneered lighter-weight heavy-duty PTOs. Notably, Bezares partnered with Eaton; since 2019 Eaton acts as Bezares\u2019 North American distributor, enabling easier access to Bezares PTOs in the U.S. market. This global reach and cross-compatibility are a hallmark of Bezares\u2019 approach.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"h-pto-usage-in-heavy-on-off-highway-trucks\">PTO Usage in Heavy On\/Off-Highway Trucks<\/h5>\n\n\n\n<p>In heavy trucks, PTOs are used to transfer engine power to auxiliary equipment. On highway trucks (dump trucks, utility vehicles, tankers, etc.), PTOs typically mount to the transmission (side or bottom openings) to drive hydraulic pumps for dump beds, winches, blowers (pneumatic offloading), or fire pumps. Off-highway and severe-service trucks (oilfield rigs, heavy wreckers, etc.) often require extra heavy-duty PTOs or multiple PTO outputs to run high-demand equipment. All three manufacturers provide PTO solutions for both on-road vocational trucks and off-road specialty applications:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"padding-bottom:var(--wp--preset--spacing--20)\"><strong>Muncie<\/strong> PTOs are ubiquitous in North American work trucks such as dump trucks, utility\/service trucks, wreckers, and refuse trucks. Their products cover small 6-bolt PTOs for medium-duty transmissions up through 8-bolt and 10-bolt PTOs for Allison automatics and Eaton UltraShift\/Endurant. Muncie PTOs are often factory options on U.S. truck chassis. For extreme needs (e.g. large vacuum trucks or drill rigs), Muncie also makes <strong>split-shaft PTO units<\/strong> that mount in the driveline to provide multiple high-torque outputs (the SS66 model handles up to 2,900 lb\u00b7ft through-shaft, and the larger SSH2\/SSV2 up to 21,600 lb\u00b7ft).<br>    <\/li>\n\n\n\n<li style=\"padding-bottom:var(--wp--preset--spacing--20)\"><strong>Chelsea (Parker)<\/strong> PTOs likewise span light to heavy. Parker\u2019s lineup includes legacy 6-bolt PTOs (e.g. 442\/489 series) commonly used on manual transmissions, 8-bolt PTOs for heavy manual or auxiliary transmissions, and 10-bolt <strong>powershift<\/strong> PTOs for popular automatics like the Allison 3000\/4000 series. Parker also produces <strong>split-shaft PTO gearboxes<\/strong> (e.g. the Chelsea 912 series) that provide multiple PTO openings when a transmission has none or only one \u2013 the 912 offers three 8-bolt PTO ports for Class 7\u20138 trucks, letting operators drive multiple implements simultaneously.<br>    <\/li>\n\n\n\n<li><strong>Bezares<\/strong> PTOs see heavy use in Europe, Latin America, and Asia on a wide range of trucks \u2013 from European brands (DAF, Iveco, Scania, Mercedes, etc.) to American makes. They offer models for popular gearboxes like ZF manuals, Mercedes and Volvo automated transmissions, and Allison automatics. Bezares emphasizes high performance under harsh conditions \u2013 their PTOs use robust cast iron housings, large bearings, and quality seals to ensure reliability. In practice, Bezares PTOs are found in applications like tippers, concrete mixers, refuse trucks, and heavy rescue vehicles worldwide. Their designs often prioritize weight savings; for example, the heavy Bezares 8500 series is <strong>10\u201320% lighter<\/strong> than competing models for the same torque. This can benefit off-road trucks where weight and space are at a premium.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"h-product-line-differences-and-key-features\">Product Line Differences and Key Features<\/h5>\n\n\n\n<p>Each manufacturer\u2019s PTO product line covers similar functions, but there are some differentiators in design and technology:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"padding-bottom:var(--wp--preset--spacing--20)\"><strong>Muncie PTO Line:<\/strong> Muncie\u2019s flagship PTO is the <em><strong><a href=\"\/products\/ptos\/muncie-tg-series\/\">TG Series<\/a><\/strong><\/em>, a versatile double-gear 6-bolt PTO that has become an industry standard. The TG is known for its modularity \u2013 it offers <strong>10 speed ratios, 13 shift types, 10 output shaft options, and 11 input gears<\/strong> to fit most transmissions. The TG\u2019s aluminum housing keeps weight low and helps dissipate heat. Muncie also produces heavy 8-bolt PTOs like the <em>82 Series<\/em> for high-torque needs. The 82 Series (cast iron housing) handles up to <strong>500 lb\u00b7ft<\/strong> and 95 HP, with options for dual hydraulic pumps and air shift. For fully automatic transmissions, Muncie\u2019s <em>CS (Clutch Shift) Series<\/em> PTOs (e.g. CS10\/11) incorporate an internal wet clutch pack and solenoid for power shifting under load. The CS10\/11 is rated to <strong>500 lb\u00b7ft<\/strong> as well, with an integrated drag brake to stop the shaft when disengaged. Notably, Muncie was first to add a <strong>drag brake<\/strong> in their clutch PTOs \u2013 a feature that prevents coasting and eases gear engagement. At the top end, Muncie\u2019s latest heavy-duty PTOs (e.g. CS40 Series) extend torque capacity into the ~600 lb\u00b7ft range for extreme applications. Muncie also offers specialized units like reversible PTOs for winches and the aforementioned split-shaft gearboxes (SS series) for multiple outputs. Overall, Muncie emphasizes broad flexibility, ease of installation, and integration with common truck transmissions in North America.<br><\/li>\n\n\n\n<li style=\"padding-bottom:var(--wp--preset--spacing--20)\"><strong>Parker Chelsea PTO Line:<\/strong> For manual transmissions, Chelsea\u2019s classic 6-bolt units (the old 442 series and current <strong>489 series<\/strong>) are widely used. The 489 is a one-piece cast iron PTO that simplified the older two-piece 442 design, reducing leak points and installation time. It provides the same torque as the 442 but with greater flexibility \u2013 <strong>27 output options, 11 internal gear ratios, and 15 shift configurations<\/strong> are available. On the heavy-duty end, Chelsea\u2019s 8-bolt <em>880 Series<\/em> is a constant-mesh mechanical PTO designed for tough jobs. The 880 handles up to <strong>500 lb\u00b7ft<\/strong> torque intermittently and is built with robust tapered bearings and a durable cast iron housing. Its high-speed gearing makes it popular for large blower and fire pump drives. For modern automatics, Parker introduced the <em>280 Series<\/em> powershift PTO, which merged the earlier 277\/278 models into a single 10-bolt PTO with significant improvements. The 280 Series has a <strong>single continuous-duty torque rating<\/strong> (no intermittent derate) and expanded to 9 speed ratios. Features like rotatable pump flanges for better clearance and a built-in pressure lubrication hose are standard. Chelsea further pushed innovation with the <em>871 Series<\/em> \u2013 a compact 10-bolt PTO for Allison 3000\/4000 transmissions that boasts up to <strong>670 lb\u00b7ft<\/strong> torque capacity continuously (no need to de-rate for continuous use). The 871 introduced options for <strong>Quiet Gear\u2122<\/strong> (lower noise operation), <strong>SmartStart<\/strong> (soft start to reduce shock), and <strong>Wet Spline<\/strong> lube \u2013 Parker is unique in offering all three in one PTO. This focus on high-tech solutions to improve durability (e.g. eliminating spline fretting with oil lube) and reduce NVH is a Chelsea hallmark. Additionally, Parker offers many specialty PTOs: constant-mesh non-shift PTOs (e.g. 877 series) for continuous drives, <strong>split-shaft PTO boxes<\/strong> like the 912 (with three PTO ports) for complex rigs, and various dual-output and reversible models. Parker\u2019s PTOs generally come with a standard 2-year warranty, reflecting their confidence in durability.<br>   <\/li>\n\n\n\n<li><strong>Bezares PTO Line:<\/strong> <a href=\"\/products\/ptos\/bezares-ptos\/\">Bezares produces an equally wide array of PTOs<\/a>, often categorized by the transmission brand or type. Their <strong>1000 Series<\/strong> and <strong>2000 Series<\/strong> PTOs cover standard 6-bolt and 8-bolt manual transmission openings, respectively. For example, the 1000 Series is a two-gear, single-speed PTO for SAE 6-bolt patterns, built in cast iron with large 12&nbsp;mm mounting hardware for strength. Its torque capacity is on the order of 250\u2013300 lb\u00b7ft (around 49 HP at 1000 RPM) depending on gear ratio \u2013 comparable to other brands\u2019 standard-duty PTOs. Moving up, Bezares\u2019 <strong>3151 Series<\/strong> is a heavy-duty constant-mesh PTO for popular automatics (Allison MD\/HD and Caterpillar transmissions). The 3151 is a 10-bolt side mount PTO that handles up to <strong>500 lb\u00b7ft<\/strong> intermittent and 400 lb\u00b7ft continuous torque (approx 95 HP), similar to Muncie\u2019s and Chelsea\u2019s offerings. It features a robust internal lubrication system and can mount on either side of the transmission, with multiple pump flange outputs (SAE B, BB, C, etc.) for versatility.<br><br>A standout in Bezares\u2019 lineup is the <strong>8500 Series<\/strong> \u2013 an 8-bolt \u201csuper heavy-duty\u201d PTO targeted at the same niche as the Chelsea 880 and Muncie 82\/828. The 8500 is rated up to <strong>500 lb\u00b7ft<\/strong> as well, but as mentioned, it\u2019s built lighter (10\u201320% weight reduction) while still using a robust housing and oversized bearings. This reflects Bezares\u2019 design philosophy of optimizing material use without sacrificing power. Bezares also offers many specialty PTOs: <strong>dual output PTOs<\/strong> (e.g. 4250 Series) that have two independently shiftable outputs for driving two accessories at once, <strong>splitter gearboxes<\/strong> (intermediate split-shafts) for mounting multiple PTOs where transmissions lack openings, and <strong>rear mount PTOs<\/strong> for transmissions like the Mack mDrive\/Volvo I-Shift. Overall, Bezares PTOs are recognized for ruggedness and adaptability \u2013 they often advertise full compatibility with the PTO apertures and pump mounts of all major truck makes. Their growing presence in North America via Eaton indicates their PTOs meet the demanding standards of American heavy truck operators as well.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group has-tertiary-background-color has-background has-global-padding is-layout-constrained wp-container-core-group-is-layout-9e9be3cb wp-block-group-is-layout-constrained\" style=\"padding-top:var(--wp--preset--spacing--20);padding-right:var(--wp--preset--spacing--20);padding-bottom:var(--wp--preset--spacing--20);padding-left:var(--wp--preset--spacing--20)\">\n<h5 class=\"wp-block-heading\" id=\"h-comparison-of-top-pto-models-and-specifications\">Comparison of Top PTO Models and Specifications<\/h5>\n\n\n\n<p>Each manufacturer\u2019s range covers overlapping capabilities.

A ductile iron strengthened bearing housing (+117% strength over prior designs) controls vibration from modern diesel engines. This PTO is targeted at extreme-duty uses like large fire pumps, high-volume blowers, and continuous-duty industrial trucks where others might require cool-down periods.<\/td><td><em>No dedicated model above 500&nbsp;lb\u00b7ft.<\/em> Bezares typically meets ultra high torque needs with split-shaft gearboxes or dual-output systems rather than a single PTO. The 3151 Series (500&nbsp;lb\u00b7ft) remains their top trans-mounted PTO. However, Bezares\u2019 strategy for beyond-500&nbsp;lb\u00b7ft is to use an <strong>intermediate splitter box<\/strong> (see below) that can deliver up to 900+ lb\u00b7ft through multiple PTO outputs. This approach sacrifices direct transmission mounting in favor of massive through-torque capacity, as often required in off-road and specialized trucks.<\/td><\/tr><tr><td><strong>Split-Shaft \/ Multi-Output<\/strong> <em>(Standalone PTO Gearboxes in Driveline)<\/em><\/td><td><strong>SSH2\/SSV2 Split-Shaft<\/strong> \u2013 Muncie\u2019s heavy split-shaft PTOs mount in the truck driveline to provide two or more PTO outputs. The SSH2 (horizontal) and SSV2 (vertical) units can take <strong>21,600&nbsp;lb\u00b7ft<\/strong> of input torque through the shaft and provide up to <strong>936&nbsp;lb\u00b7ft<\/strong> torque on each PTO output. They include multiple 8-bolt and 6-bolt openings for standard PTOs and can be shifted by air or electric actuators. These are used on very large rigs (airport crash tenders, mobile drill rigs, etc.) where transmission-mounted PTOs alone can\u2019t supply enough power or quantity of outputs.<\/td><td><strong>912 Split-Shaft<\/strong> \u2013 Parker\u2019s solution for Class 7\u20138 trucks needing extra PTOs. The 912 is basically a transfer case that offers <em>three<\/em> 8-bolt PTO mounting apertures. It accepts the truck\u2019s driveshaft input (available with 1610\/1710\/1810 series yokes) and can be engaged via air or lever. This unit allows multiple hydraulic pumps or accessories to run simultaneously. Throughput torque is on the order of 15,000+ lb\u00b7ft, with each PTO pad capable of driving a standard Chelsea PTO (which in turn can output hundreds of lb\u00b7ft each). The 912 and its smaller sibling 901\/941 series cover trucks with automatics that lack enough factory PTO openings.<\/td><td><strong>Splitter Boxes &amp; Dual PTOs<\/strong> \u2013 Bezares offers various intermediate gearboxes to multiply PTO outputs. For example, their <strong>\u201cSB\u201d Splitter Box<\/strong> products provide twin PTO apertures (6- or 8-bolt) to drive two pumps from one transmission output. They also have a <strong>820 Series twin-output gearbox<\/strong> which can mount two pumps with independent gear ratios for each. For maximum simultaneous outputs, Bezares even has a special 3-output gearbox (allowing three pumps at once). Additionally, the <em>4250 Dual Output PTO<\/em> is an 8-bolt transmission PTO with two separate air-shifted outputs in one unit. These solutions showcase Bezares\u2019 focus on flexibility \u2013 instead of a single giant PTO, they provide systems to combine multiple PTO functions to meet high power demands. This is particularly useful in European heavy haul and military trucks that require compact multi-functional PTO arrangements.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"has-small-font-size\"><em><strong>Table:<\/strong> Comparative overview of five PTO categories \u2013 standard-duty 6-bolt PTOs, heavy 8-bolt PTOs, 10-bolt clutch-shift PTOs, ultra high-torque PTO solutions, and split-shaft\/multiple-output systems \u2013 from Muncie, Parker Chelsea, and Bezares.

However, the differentiators like noise reduction, ease of maintenance, and multi-output capability can sway the decision. For example, a fire tanker build might favor a Chelsea 871 for its quiet, high-torque continuous operation, while a heavy wrecker might opt for Muncie\u2019s split-shaft for running several winches at once, and a European tipper might use a Bezares PTO for its lighter weight on a given transmission.<\/p>\n\n\n\n<p>All three companies have a rich legacy \u2013 from Muncie\u2019s 85+ years in Indiana to Chelsea\u2019s origins in PTO design to Bezares\u2019 global expansion since the 1950s \u2013 and they continue to innovate PTO technology. Ultimately, truck builders and upfitters benefit from this competition, as today\u2019s PTOs are more powerful, reliable, and tailored to specialized needs than ever before. By understanding the strengths of Muncie, Chelsea, and Bezares product lines, one can select the optimal PTO solution to efficiently and safely harness engine power for any heavy-duty job at hand. <a href=\"\/contact\/\">Contact us today to get a quote and discuss your PTO needs with an expert<\/a>.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group alignfull has-background has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\" style=\"background:linear-gradient(180deg,rgb(244,244,244) 0%,rgb(255,255,255) 100%);margin-top:0;margin-bottom:0;padding-top:var(--wp--preset--spacing--20);padding-bottom:var(--wp--preset--spacing--20)\">\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center has-medium-font-size\" id=\"h-recent-knowledge-base-articles\">Recent Knowledge Base Articles<\/h3>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\t\t<div class=\"wppsac-wrap wppsac-slick-carousel-wrp wppsac-clearfix \" data-conf=\"{&quot;slides_to_show&quot;:3,&quot;slides_to_scroll&quot;:1,&quot;dots&quot;:&quot;true&quot;,&quot;arrows&quot;:&quot;true&quot;,&quot;autoplay&quot;:&quot;true&quot;,&quot;autoplay_interval&quot;:4000,&quot;speed&quot;:600,&quot;rtl&quot;:&quot;false&quot;,&quot;lazyload&quot;:&quot;&quot;}\">\r\n\t\t\t<div id=\"wppsac-post-carousel-1\" class=\"wppsac-post-slider-init wppsac-post-carousel design-1\">\r\n\t\t\t\t<div class=\"wppsac-carousel-slides\">\r\n\t\t<div class=\"wppsac-post-image-bg\">\r\n\t\t<a href=\"https:\/\/generaltruckparts.com\/the-universal-joint-the-connecting-link-of-the-heavy-duty-truck-driveline\/\">\r\n\t\t\t<img decoding=\"async\" class=\"wppsac-post-image\"  src=\"https:\/\/generaltruckparts.com\/wp-content\/uploads\/2025\/12\/Banner-U-Joints-300x129.avif\" alt=\"The Universal Joint: The Connecting Link of the Heavy-Duty Truck Driveline\" \/>\r\n\t\t<\/a>\r\n\t<\/div>\r\n\t\r\n\t<div class=\"wppsac-post-content-position\">\r\n\t\t\r\n\t\t<h2 class=\"wppsac-post-title\">\r\n\t\t\t<a href=\"https:\/\/generaltruckparts.com\/the-universal-joint-the-connecting-link-of-the-heavy-duty-truck-driveline\/\">The Universal Joint: The Connecting Link of the Heavy-Duty Truck Driveline<\/a>\r\n\t\t<\/h2>\r\n\r\n\t\t\t\t<div class=\"wppsac-post-date\">\r\n\t\t\tDecember 1, 2025\t\t<\/div>\r\n\t\t\t\t<div class=\"wppsac-post-content\">\r\n\t\t\t<div class=\"wppsac-sub-content\">From the early days of mechanical engineering to today\u2019s heavy-duty commercial trucks, the U-joint has been the link holding everything&#8230;<\/div>\r\n\r\n\t\t\t\t\t\t<a class=\"wppsac-readmorebtn\" href=\"https:\/\/generaltruckparts.com\/the-universal-joint-the-connecting-link-of-the-heavy-duty-truck-driveline\/\">Read More<\/a>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n<\/div><div class=\"wppsac-carousel-slides\">\r\n\t\t<div class=\"wppsac-post-image-bg\">\r\n\t\t<a href=\"https:\/\/generaltruckparts.com\/understanding-the-relationship-between-the-clutch-and-transmission-in-heavy-duty-truck-drivelines\/\">\r\n\t\t\t<img decoding=\"async\" class=\"wppsac-post-image\"  src=\"https:\/\/generaltruckparts.com\/wp-content\/uploads\/2025\/10\/transmission-clutch-schematic2-300x125.avif\" alt=\"Understanding the Relationship Between the Clutch and Transmission in Heavy-Duty Truck Drivelines\" \/>\r\n\t\t<\/a>\r\n\t<\/div>\r\n\t\r\n\t<div class=\"wppsac-post-content-position\">\r\n\t\t\r\n\t\t<h2 class=\"wppsac-post-title\">\r\n\t\t\t<a href=\"https:\/\/generaltruckparts.com\/understanding-the-relationship-between-the-clutch-and-transmission-in-heavy-duty-truck-drivelines\/\">Understanding the Relationship Between the Clutch and Transmission in Heavy-Duty Truck Drivelines<\/a>\r\n\t\t<\/h2>\r\n\r\n\t\t\t\t<div class=\"wppsac-post-date\">\r\n\t\t\tOctober 27, 2025\t\t<\/div>\r\n\t\t\t\t<div class=\"wppsac-post-content\">\r\n\t\t\t<div class=\"wppsac-sub-content\">The clutch and transmission are two of the most critical components in a heavy-duty truck\u2019s driveline.
