Description

When your tractor’s four-wheel drive starts slipping or won’t engage properly, the coupling that transfers power to your front axle is often the culprit. The 4WD coupling is the critical link that transfers power to your front axle, and when it fails, you lose the traction needed for demanding field conditions. This precision-built coupling restores that reliable power transfer so you can tackle tough jobs with confidence.

What You’re Getting

10-spline design ensures positive engagement without slipping under load
Precision dimensions – 74mm length with 40mm outer diameter for exact OEM fit
Heavy-duty construction built to handle the high-torque demands of 4WD operation
Direct replacement part – no modifications or adapters needed

Built for Real Farm Work

This coupling fits a wide range of Fiat tractors from the compact 66 series through the powerful 94 series, plus Case IHC JX models. Whether you’re running a utility tractor for loader work or a bigger machine for heavy field operations, this is the same quality coupling that came from the factory. It’s designed to handle everything from muddy spring field work to steep hillside mowing where you need all the traction you can get.

Made to Last

Farm equipment couplings take serious abuse – shock loads when hitting rocks, constant engagement and disengagement, and exposure to mud, moisture, and debris. This coupling is built with quality materials and precise manufacturing to handle those demands. The splines are cut to exact tolerances and heat-treated for durability that lasts season after season.

Good to Know

Installation is straightforward, but take time to clean the mating surfaces and check for any debris in the coupling area. A light coat of grease on the splines helps with installation and prevents corrosion. If you’ve been having engagement problems, inspect the entire 4WD system while you’ve got the coupling apart – worn shift forks or damaged housings can cause premature coupling wear.
