Description
When your oil pressure starts dropping or you’re hearing that telltale engine knock, there’s a good chance your oil pump rotor is worn out. This little part sits right at the heart of your tractor’s lubrication system, spinning away to keep oil flowing to all the critical engine parts. Without proper oil circulation, those vintage Continental engines in the TE20s and early MF tractors won’t last long under a load.
What You’re Getting
- Precision-machined rotor with the distinctive slit design that fits Continental Z-series engines
- Proper clearances and geometry to maintain oil pressure across all RPM ranges
- Durable construction that handles the demands of agricultural work cycles
- Direct replacement for worn original rotors – no modifications needed
Built for Real Farm Work
This rotor fits the petrol engines in Massey Ferguson TE20, MF35 Petrol, and MF135 tractors – those dependable workhorses that helped build modern agriculture. These tractors spent decades running everything from mowers and cultivators to small balers and loader work, and their Continental petrol engines were known for reliability when properly maintained.
Made to Last
Your Continental engine depends on steady oil pressure to keep those close-tolerance parts happy. This rotor is built to the same specs as the original, with proper metallurgy to handle the constant spinning and oil flow demands. It’s designed to work with the gear-type oil pumps in these engines, maintaining the pressure your vintage tractor needs.
Installation Notes
Replacing the oil pump rotor means dropping the oil pan and pulling the pump assembly. While you’re in there, it’s smart to check the pump body and gears for wear too. The distinctive slit at one end of the shaft ensures proper alignment with the drive gear. Always prime the oil system and check pressure with a mechanical gauge after reassembly.
