Description of Change: A new crankshaft front seal is now available. The new seal incorporates both the seal and the wear sleeve together. The new crankshaft front seal has a redesigned wear sleeve that has a flanged face. This new flanged face rotates with the crankshaft in order to keep dirt away from the sealing lip. This will provide better control of contaminants.The removal procedure of the new seal has been changed because of the new flanged face on the wear sleeve. The seal face is blocked by the new flanged face on the wear sleeve.Adaptable To: The new crankshaft front seal is adaptable to all 3400 engine models. The new crankshaft front seal is a direct replacement for either of the former seals. Refer to the 1 table below.
