Description
When your engine cranks but sounds like it’s grinding coffee beans, chances are your flywheel ring gear has worn teeth that aren’t meshing properly with the starter. This replacement ring gear gets your engine cranking smoothly again, eliminating those grinding sounds and starter slippage that can leave you stranded in the middle of a job.
Key Features
- 115 precision-machined teeth for smooth engagement with your starter
- 13-7/16 inch inside diameter sized specifically for Perkins diesel engines
- Heat-treated steel construction resists wear and tooth breakage under heavy use
- Direct replacement for OEM specs – no modifications needed
Built for Real Farm Work
This ring gear fits the Perkins engines found in a huge variety of Massey Ferguson tractors, from the compact MF35 and MF65 utility tractors up through the bigger MF300 and MF400 series machines. Whether you’re running a small MF135 for hay work or a larger MF390 for row crops and heavy tillage, these are the reliable workhorses that power everything from three-point implements to PTO-driven equipment day after day.
Made to Last
Engine starting components take a beating every single day, especially during cold weather starts. This gear is manufactured from quality steel with proper heat treatment to handle the shock loads from starter engagement and the temperature extremes of agricultural service. The precise tooth geometry ensures clean engagement and long service life.
Installation Notes
Ring gear replacement requires removing the transmission and flywheel, so many operators combine this job with clutch replacement or other engine work. The gear is typically press-fitted or shrink-fitted to the flywheel, so proper heating and cooling procedures are essential for installation. If your old gear failed, check your starter condition – worn starters can damage new ring gears prematurely.
