Description

When you hear that tell-tale knocking from your Massey’s engine or notice the crankshaft moving back and forth more than it should, your thrust washers are calling it quits. These small but mighty washers keep your crankshaft exactly where it needs to be – not walking forward into your clutch or backing up into your flywheel. Without good thrust washers, you’ll be looking at some serious engine damage that’ll cost way more than this simple fix.

What You’re Getting

Complete set with all the thrust washers your Perkins engine needs for a proper rebuild
Precision-ground to factory specs so your crankshaft end play stays right where it should be
Works with both rope seal and lip seal crankshafts – just make sure you know which type you’ve got
Available in standard size and oversize for engines that have seen some wear

Built for Real Farm Work

This set fits your Massey Ferguson 135, 148, 240, 250, 550, and 35X tractors with those reliable Perkins A3.144, A3.152, and AD3.152 engines. These are the tractors that handle everything from hay operations to loader work, where the engine sees plenty of thrust loads that can wear out washers over time. Whether you’re pushing through tough ground or pulling heavy implements, these engines work hard and need proper thrust control to keep running strong.

Made to Last

Your Perkins engine’s thrust washers might be tucked away inside, but they’re working every time you start up. These replacement washers are built to handle the constant pressure and movement that comes with farm work. They’re made from materials that can take the heat cycles and loads your engine dishes out, season after season.

Installation Notes

Always measure your crankshaft end play with a dial indicator before and after installation – you want between 0.004 and 0.008 inches of play. If you’re working with a reground crank, watch out for metric flywheel bolts instead of the original imperial threads. Pay attention to which way the oil grooves face when you install them – your service manual will show the correct orientation for proper lubrication.
