Description
When your CVT transmission starts making noise or you’ve lost power getting to your front wheels, chances are you’re dealing with worn drive shaft splines. This critical component connects your transmission to the front differential, transferring engine power where you need it most – whether you’re pulling through muddy fields, climbing hills with a full grain cart, or pushing silage around the yard. A worn shaft means lost traction when you can least afford it.
What You’re Getting
- Precision-machined splines (14 and 12 spline configurations) that engage properly without slop or binding
- Heat-treated steel construction designed to handle full engine torque under demanding field conditions
- Factory-correct dimensions that fit perfectly without modifications or adjustments
- Proper bearing surfaces and sealing areas to keep lubricants where they belong
- Direct replacement for worn factory shafts in your CVT-equipped tractor
Built for Real Farm Work
This drive shaft powers the demanding work these modern CVT tractors are built for – heavy tillage operations, large-scale planting and harvesting, loader work around the farmyard, and transport duties with heavy implements. The T6 and T7 series handle everything from dairy operations to row crop farming, while the Case Puma and Steyr CVT models excel in similar demanding agricultural applications where reliable four-wheel drive is essential.
Made to Last
Farm equipment takes a beating, and transmission components see some of the highest stress loads on your tractor. This shaft uses specialized heat treatment that creates hard-wearing spline surfaces while keeping the core tough enough to handle shock loads. The precision machining eliminates the play that causes rapid wear, and proper sealing surfaces help keep contaminants out of your expensive transmission.
Installation Notes
This is a transmission-out job that requires dropping major driveline components, so plan on dedicating most of a day if you’re tackling it yourself. While you’ve got things apart, it’s smart to inspect the related universal joints, seals, and differential components. Check your specific tractor model for the correct spline count – some applications use 14 splines while others use 12 splines, and they’re not interchangeable.
