Description

That growing puddle of oil under your Allis Chalmers isn’t just messy—it’s expensive oil dripping away and a sign your trusty tractor needs some attention. At today’s oil prices, even a small leak gets expensive fast, not to mention the engine damage that can occur from low oil levels. This replacement oil pan gasket seals the bottom of your engine, keeping oil where it belongs instead of all over your shop floor.

What You’re Getting

Precise fit gasket designed specifically for 138 and 149 CID 4-cylinder gas engines
Quality gasket material that resists the compression set and heat cycling that causes old gaskets to fail
Direct replacement that installs without modifications or trimming
Durable construction that handles the vibration and temperature changes of farm work

Built for Real Farm Work

For D10 Series, D12 Series, D14 Series, D15 Series tractors with 4-Cylinder Gas, 138 CID and 4-Cylinder Gas, 149 CID engines. These reliable workhorses are found on farms everywhere, handling everything from daily chores to field work. Whether you’re running a loader, pulling implements, or doing general farm maintenance, proper oil sealing is critical for engine longevity.

Made to Last

This gasket uses materials specifically chosen to withstand the hot oil environment and constant temperature cycling that destroys cheaper alternatives. The proper thickness ensures correct pan fit and sealing, while the quality construction resists degradation from exposure to farm conditions and engine oils.

Installation Notes

Clean both mating surfaces thoroughly – any old gasket material or dirt guarantees a comeback leak. Torque the pan bolts evenly in a crossing pattern to ensure uniform gasket compression. Check your oil pan for dents or warpage while you’ve got it off – a bent pan will never seal properly no matter how good the gasket is. Don’t use gasket sealer unless specifically required and remember to let things cure before adding fresh oil.
