Description
When your starter just spins or grinds against worn teeth, or you’re hearing that dreaded metal-on-metal sound during cranking, it’s time to look at your flywheel ring gear. This 115-tooth ring gear is what your starter pinion engages with to get your engine turning over. A worn or damaged ring gear turns starting your tractor from a simple key turn into a frustrating ordeal.
What You’re Getting
- Precision-manufactured 115 teeth with proper tooth profile for smooth starter engagement
- 340mm inner diameter designed for proper flywheel fit on Perkins engines
- Heat-treated steel construction that handles repeated starter engagement
- Direct replacement for multiple OEM part numbers across Massey Ferguson and Perkins applications
- Compatible with both naturally aspirated and turbocharged engine configurations
Built for Real Farm Work
This ring gear fits a massive range of Massey Ferguson tractors from the classic 35 utility tractor through the heavy-duty 800 series, plus Perkins 3.152, 4.203, 4.236, and 4.248 engines used across multiple brands. Whether you’re running a small 135 for hay work, a mid-size 265 for cultivation, or a bigger 390 for heavy tillage, this gear keeps your engine starting reliably season after season.
Made to Last
Ring gears take tremendous stress from starter engagement, especially on cold mornings or after long periods of sitting. This gear is manufactured from high-grade steel with proper heat treatment to resist wear and chipping. The precise tooth geometry ensures smooth engagement with your starter drive, reducing the grinding and wear that shortens both components’ life.
Installation Notes
Ring gear replacement requires flywheel removal, which means splitting the tractor between engine and transmission – not a backyard job for most folks. The new ring gear typically needs to be heated for expansion and pressed onto the flywheel while hot. If you’re tackling this yourself, make sure you have the proper tools and workspace. Many farmers find this is worth having done professionally to ensure proper installation and avoid expensive mistakes.
