Description

When your Case tractor starts seeping oil from the bottom end or you’re planning a major engine rebuild, you need more than just individual gaskets—you need a complete lower gasket set that seals everything properly the first time. This comprehensive kit takes the guesswork out of lower engine sealing, giving you everything needed to button up your A451BD engine from the oil pan to the crankshaft seals.

What You’re Getting

Complete lower gasket set covers oil pan, timing cover, and all bottom-end sealing points
Includes both front and rear crankshaft seals to prevent oil leaks at shaft exits
Quality construction handles the heat cycles and pressure of diesel operation
All gaskets cut to exact specifications for proper fit and long-lasting seals
One complete kit services either standard or turbocharged A451BD engines

Built for Reliable Power

The A451BD was Case’s workhorse 6-cylinder diesel found in many of their utility and row-crop tractors from that era. Whether your engine is naturally aspirated or equipped with a turbocharger, it’s built to handle serious work—but only when properly sealed. These engines power everything from loader work to heavy tillage, and a good seal job means you can focus on the work instead of oil spots in the shop.

Made to Last

Farm engines take a beating with constant temperature changes, vibration, and long hours under load. These gaskets are manufactured to handle those conditions, using materials that stay flexible and maintain their seal through countless heat cycles. The included crankshaft seals use modern rubber compounds that resist the additives in today’s engine oils.

Good to Know

If you’re doing a bottom-end rebuild, this is the time to replace all these seals—not just the ones that are obviously leaking. Clean all mating surfaces thoroughly and check for warpage before installation. The crankshaft seals install easier with a thin coat of assembly lubricant, and take your time getting them seated evenly to avoid damage during installation.
