Give a new front crankshaft seal a fresh surface to ride on with the National Oil Seal Crankshaft Repair Sleeve, part number 99248. It is a direct-fit replacement for the listed applications, including the 1994-2009 Dodge RAM 2500 and 1994-2007 Dodge RAM 3500 [L6-5.9L], the 1989-1993 Dodge D250, D350, W250 and W350 [L6-5.9L], the 1971-1980 International Scout II [L4-3.2L, V8-5.0L, V8-5.6L], and a long list of International trucks going back to the 1950s. See the Buyer's Guide tab for all 343 applications.

Over time, a seal lip can wear a groove into the shaft surface it rides on, and a new seal installed on that groove may continue to leak. An engine crankshaft repair sleeve is designed to press over the worn area and give the new seal a smooth contact surface. It is intended as an alternative to replacing or machining the crankshaft.

  • Position: front crankshaft seal surface.
  • Purpose: provides a new contact surface for the front crankshaft seal lip over a worn or grooved area.
  • Quantity: the listed applications use one sleeve.
  • Install tip: replace the front crankshaft seal at the same time, and follow the vehicle service information for installation.

Signs this part may be needed: oil seeping from the front of the engine at the crankshaft seal, or a visible groove worn where the old seal lip rode. If a worn seal surface is causing the leak, this sleeve addresses it. Diagnose the leak source before replacing parts.
