What Is a Splined Yoke 13 With Collar?<\/h2>\n

\"SplinedThe Splined Yoke 13 With Collar is a critical connection component used within PTO drive shaft assemblies across a wide range of agricultural and light-industrial machinery. The collar feature\u2014sometimes called a locking collar or retaining collar\u2014provides a secondary retention point on the splined bore, preventing axial displacement under high-torque or vibration-intensive conditions. This is particularly valuable on UK farms where ground conditions regularly subject driveline components to unpredictable shock loads: think heavy cultivation behind a high-horsepower tractor, or bale transport on uneven Lincolnshire or Yorkshire terrain.<\/p>\n

Carrying a standard 1 3\/8″ bore diameter (E = \u03a613 on the majority of series) with either Z6 or Z21 spline configurations, the yoke interfaces directly with standard tractor PTO output shafts in compliance with ISO 500 and ASAE S303 dimensional standards. The \u03a616 variant available in the 8.0513C \/ 8.0513E models extends compatibility to heavier-duty drive-shaft assemblies often found in municipal or construction equipment in Britain. Whether sourced for replacement on an ageing Fendt driveline or as original equipment on a newly assembled spreader, these yokes deliver the geometric precision that keeps power transfer smooth and losses minimal.<\/p>\n

Ever-Power manufactures the Splined Yoke 13 With Collar series across twelve distinct model configurations\u2014from compact 1.0513B to heavy-duty 8.0513E\u2014covering A-dimension cross sections between 22 mm and 36 mm and C-dimension overall lengths from 100 mm to 137 mm. The result is a product family broad enough to satisfy most OEM replacement scenarios without the delays typical of custom fabrication, keeping British machinery operators productive through the season.<\/p>\n<\/div>\n

Material, Working Principle & Application Scenarios<\/h2>\n
\n
\n

Material Stack<\/h4>\n

The yoke body is cold-forged from 20CrMnTi alloy steel\u2014a low-carbon chromium-manganese-titanium grade that responds well to carburising heat treatment. Post-forging, spline teeth are hobbed to DIN 5480 tolerances and case-hardened to 58\u201362 HRC at the tooth surface. The collar is machined integral to the body, avoiding welded joints that can introduce stress concentration under torsional cycling. A zinc phosphate conversion coating is applied as the final surface treatment, giving a baseline salt-spray resistance and improving lubricant retention in the spline bore.<\/p>\n<\/div>\n

\n

How It Works<\/h4>\n

The yoke slots onto the tractor PTO stub shaft or gearbox output via the splined bore, transmitting rotational torque from the power source to the driven implement. The 1 3\/8″ bore (E = \u03a613) matches the near-universal ISO 500 Class 2 stub shaft found on British tractors from 35 kW upwards. The collar, positioned just behind the splined engagement zone, bears against the face of the shaft guard or an internal circlip groove to prevent the yoke from sliding rearward under thrust reversals\u2014a condition that can arise during sudden braking or direction changes on hillside pasture work common in Wales, Cumbria, and the Scottish Borders.<\/p>\n<\/div>\n
