Category 4 80 Degree Constant Velocity Joint with Series 35 Yoke and Splined Shaft – Equal Arm

Description

When you’re working steep ground or tight angles with heavy implements, regular universal joints just can’t handle the constant velocity changes without binding up or wearing out fast. That jerky power transfer puts stress on everything from your tractor’s PTO to the implement bearings, and nobody’s got time for broken drivelines in the middle of harvest. This Weasler Cat 4 CV joint assembly gives you smooth power transmission at angles up to 80 degrees, keeping your heavy-duty implements running steady no matter how rough the terrain gets.

What You’re Getting

• Constant velocity design eliminates the jerky motion that destroys regular U-joints at high angles
• Series 35 yoke construction built for the punishment of 40-100 HP tractor applications
• Category 4 strength handles the torque from big rotary cutters, heavy tillers, and other demanding implements
• 1-15/16 inch by 20 spline shaft provides positive engagement without slippage
• Equal arm configuration ensures balanced power transfer and reduces vibration

Built for Real Farm Work

This CV joint assembly is right at home on tractors running heavy implements where regular drivelines just can’t cut it. Think steep hillside mowing with a 15-foot batwing, deep tillage work where the implement needs to articulate over rocks and ridges, or any situation where your PTO shaft has to operate at extreme angles. The Series 35 components handle everything from utility tractors to row-crop machines in that 40-100 horsepower range.

Made to Last

Weasler doesn’t mess around when it comes to PTO components – they know your safety and productivity depend on quality construction. The CV joint housing is precision-machined to maintain exact tolerances under load, while the internal components are built to handle the constant articulation that would tear up regular universal joints. The splined shaft is heat-treated for maximum durability and precise fit.

Installation Notes

This is a direct replacement unit that bolts right up without modifications. Make sure to grease all fittings thoroughly before first use and check the spline engagement – you want full contact without binding. A quick tip from the field: when working at maximum angles, let the tractor warm up before engaging the PTO to give the joint time to distribute lubricant properly.
