Description
If your front axle drive shaft has been making noise or you’ve noticed vibration when you engage 4WD, a worn keyway could be the culprit. This small but critical component keeps the drive shaft properly aligned and transfers power from the differential to your front wheels. When it wears out, you’ll lose that front-end bite you count on for traction in tough conditions.
What You’re Getting
- Precision-cut keyway that locks the drive shaft in perfect alignment
- Heat-treated steel construction that stands up to the shock loads of 4WD engagement
- Exact replacement dimensions that match your original equipment specifications
- Part of the complete drive shaft kit system for comprehensive front axle repair
Built for Real Farm Work
This keyway fits an extensive range of New Holland tractors from the compact T5 series utility tractors up through the powerful T7 series row-crop machines, plus the full TM and TSA lineup. It’s also compatible with Case IH Puma series tractors. Whether you’re running a T6.150 with a loader or pulling heavy tillage equipment with a T7.245, this keyway handles the torque transfer that keeps your front axle pulling strong.
Made to Last
Front axle components face brutal conditions – sudden engagement loads, constant vibration, and the shock forces from hitting rocks or holes. This keyway is manufactured from quality steel with proper heat treatment to resist wear and maintain its critical dimensions. It’s designed to work as part of the complete drive shaft assembly, ensuring smooth power transfer and long service life.
Good to Know
This keyway is typically replaced as part of the complete front axle drive shaft kit (Kit 43876) for best results. If you’re experiencing front axle problems, it’s worth inspecting the entire drive shaft assembly while you have things apart. Proper installation requires front axle disassembly and specialized tools, so plan accordingly for this repair.
