This complete engine overhaul kit gives you everything you need to bring that workhorse back to life without the cost of a factory rebuild. Whether your tractor’s been plowing fields for decades or just needs a refresh, this kit contains sleeves & sleeve seals, pistons & rings, pins & retainers, pin bushings, complete gasket set, crankshaft seals to get you back to work.

Built for Real Farm Work

This overhaul kit fits the reliable 4-cylinder Perkins diesel engines found in Massey Ferguson’s workhorse tractors—from the compact 300 Series combines to the versatile MF65 and MF165 tractors that handle everything from hay work to cultivation. These are the machines you see on farms running loaders, pulling discs, and powering through long harvest days where reliability matters.

Made to Last

The Tru-Power components in this kit are built to handle the thermal stress and compression loads of diesel operation. The .150-inch sleeve flange thickness provides the durability these wet-sleeve engines need, while the two-piece rope-type rear seal design matches the original Perkins engineering that’s proven itself over decades of farm use.

Installation Notes

This is a basic kit, so you’ll need to order main and rod bearings separately based on your crankshaft measurements. The angled injectors in these cylinder heads require proper timing during assembly—if you’re not familiar with wet-sleeve Perkins engines, this is a good time to involve an experienced diesel mechanic who knows the tricks for getting everything aligned right.
