Description
If you’ve noticed your transmission making noise or not shifting between ranges as smoothly as it used to, this range box shim might be exactly what you need. These precision-machined shims control the clearances inside your transmission’s range box, ensuring proper gear mesh and smooth shifting. When internal wear or previous repairs have thrown off these critical clearances, installing the correct shim gets everything lined up right again.
What You’re Getting
- Precision-cut shim maintains proper gear clearances in your range box
- Helps eliminate grinding, whining, or binding when shifting between ranges
- Restores smooth operation and prevents accelerated gear wear
- Direct replacement part for transmission service and rebuilds
Built for Transmission Work
This shim is designed for the range boxes found in Massey Ferguson’s reliable 300 Series tractors like the 362, 365, and 390, plus the heavier-duty 4200 Series models including the 4235, 4240, and 4265. These are tractors that handle everything from row crop farming to heavy tillage work, and their transmissions need to shift cleanly under load day after day.
Made to Last
Range box shims work in one of the most demanding environments in your tractor – inside the transmission where they’re constantly bathed in oil and subjected to the forces of gear changes. This shim is manufactured to precise thickness tolerances from durable steel that won’t compress or deform over time, maintaining proper clearances for years of reliable operation.
Installation Notes
Installing shims requires splitting the transmission, so this is definitely a job for when you’re doing a range box rebuild or major transmission service. Make sure to measure existing clearances and consult your service manual for proper shim stack thickness – getting the clearance right is what makes the difference between smooth shifting and problems down the road.
