Description
There’s nothing quite like starting your Nuffield tractor and seeing a puddle of oil underneath the front end. A worn front crankshaft seal is one of those problems that only gets worse if you ignore it, and with oil prices what they are these days, every drop counts. This seal sits at the front of your engine where the crankshaft exits to drive the cooling fan and other accessories, keeping engine oil where it belongs inside the crankcase.
What You’re Getting
- Direct replacement seal that fits perfectly on your Nuffield’s crankshaft without modifications
- Quality construction designed to handle the constant rotation and vibration of farm work
- Proper seal lip material that stays flexible in cold weather and won’t harden from engine heat
- Reliable sealing that prevents oil loss and keeps dirt from entering the crankcase
Built for Real Farm Work
This seal fits the classic Nuffield 3-cylinder tractors like the 3/42, 3/45, and 3DL models, plus the 4-cylinder 10/42 and 10/60 series machines. These were solid workhorses in their day, handling everything from cultivation and hay making to general farm chores. Whether you’re restoring one of these vintage tractors or keeping a working machine in service, this front crankshaft seal helps maintain proper engine lubrication.
Made to Last
Farm tractors face conditions that would destroy automotive seals – dust, temperature swings, vibration from implement work, and extended operating hours. This seal uses materials specifically chosen for agricultural applications, with a seal lip that maintains proper contact pressure even as it wears in. The outer case stays rigid to prevent leaks around the seal housing.
Good to Know
Replacing a front crankshaft seal usually means removing the cooling fan and pulley, so it’s a good time to check your fan belt and water pump while you’re in there. Clean the seal bore thoroughly before installation and check the crankshaft surface for grooves – even minor scratches can cause a new seal to leak. A light coating of assembly lube on the seal lip helps prevent dry running during startup.
