Overrunning Clutch Cam and Spring Service Kit for Walterscheid PTO Applications

Description

When your PTO starts slipping or making noise during direction changes, the problem is often worn cams and springs in the overrunning clutch. This essential component lets your PTO shaft turn freely in one direction while locking in the other—protecting your equipment when the implement tries to back-drive the tractor. When these internal parts wear out, you’ll notice reduced power transfer and potentially costly damage to your driveline.

What You’re Getting

• Complete service kit with 2 cams and 2 springs for one overrunning clutch rebuild
• Precision-manufactured components designed to restore proper clutch engagement
• Direct replacement for Walterscheid reference numbers 16-50-35 and 66-19-01
• Quality Weasler construction that meets OEM specifications

Built for Real Farm Work

This kit services the F5 size overrunning clutch commonly found in Walterscheid PTO shafts. These clutches are critical components in PTO drivelines connecting tractors to implements like mowers, balers, spreaders, and other equipment where sudden stops or reversals could damage the tractor’s PTO system. The overrunning feature protects your investment by preventing back-drive forces from reaching your tractor’s transmission.

Made to Last

Farm equipment demands reliability, and PTO components take some of the hardest abuse on the farm. These cams and springs are manufactured to withstand the constant cycling, high torque loads, and environmental conditions that PTO systems face. The hardened cam surfaces and properly tempered springs ensure consistent operation season after season.

Installation Notes

This is a complete service kit for rebuilding one overrunning clutch assembly. You’ll need to disassemble the clutch housing to access the internal components—have a clean workspace and proper tools ready. Individual parts aren’t available separately, so this kit ensures you have everything needed for a complete repair. A quick tip: mark the cam positions before disassembly to ensure proper reassembly timing.
