Description
When your Massey Ferguson starts grinding gears or won’t shift smoothly into 3rd speed, this replacement gear might be exactly what you need. This 41-tooth gear sits on the top shaft of your transmission and transfers power through the 3rd speed range – one of the most commonly used gears for field work and road travel. A worn or damaged gear means rough shifting, gear slippage, or complete loss of that speed range.
What You’re Getting
- Precision-machined 41-tooth gear designed to factory specifications
- Heat-treated steel construction for long service life under heavy loads
- Proper tooth profile and spacing for smooth gear engagement
- Direct replacement that fits right on your existing top shaft assembly
Built for Real Farm Work
This gear fits a wide range of popular Massey Ferguson models from the reliable 100 series utility tractors through the powerful 4300 series machines. Whether you’re running a smaller 135 for loader work around the farmstead or putting long hours on a 290 pulling implements, 3rd gear sees plenty of use. These tractors handle everything from hay operations and row crop farming to livestock work and general farm duties.
Made to Last
Transmission gears take tremendous stress from constant load changes, shock loads, and the vibration of field work. This replacement gear is manufactured to handle those conditions with proper metallurgy and heat treatment. The tooth geometry is cut to mesh smoothly with the other transmission components, reducing noise and extending the life of your entire transmission.
Good to Know
This gear is part of kit 63152 if you’re doing a complete transmission rebuild, but it’s also available separately for targeted repairs. Transmission work requires splitting the tractor, so it’s a job for someone comfortable with major mechanical work or best left to a qualified shop. Check your other transmission gears while you’re in there – worn gears often damage their neighboring components.
