'95 Ford F150, Crankshaft Leak
have a 95 Ford F150. The 4.9L 6 cylinder engine has a rear crankshaft
seal leaking. My question- what can I do if the seal riding surface on
the crank is grooved after I get the old one removed? Do any part suppliers
have a sleeve that can be pressed on to the crankshaft to provide a new
riding surface... Tom B.
Damage can occur any time a rubber seal rides against a metal surface
. You may ask how can a piece of rubber damage a metal part? Essentially
it isnt the rubber that does the damage. Its the dirt that
gets caught between the rubber seal and the metal that causes the damage.
Over time the dirt just wears the metal away like sand paper would. In
your case the repair is a stainless steel sleeve that is pressed on, over
the damaged area. The kit to perform this repair is call a sleeven
seal kit. Most any real parts store either stocks or can get this repair
kit. One tip, if youve never performed this type of repair, be sure
to buy the installation tool. Its a bit pricy but it costs less
than buying a couple of sleeven seal kits for practice.
