[Fot] Timing cover crank seal oil leak

[Joe Boruch]

 I took a look in my spare parts box and I found a seal (it was right on top - I am not usually so lucky in my searches), which I believe to be the correct one.  It is a Timken 473229 double lip seal.  1.562" x 2.502" x 3.13".  My engine is assembled, so I could not verify the shaft ID, but the OD is correct.  It is a fairly common seal for a transfer case (which I have no reason to have a seal for).
Googling, there is also a Timken 472635 seal, which is for a 1.552" shaft, but it is 0.500" thick.  The extra thickness may better position one seal lip away from the split between the spacer and the damper hub.  
I do not use a gasket to install the timing cover, but rather just use RTV.  Adding a gasket or two would also shift the seal's relative position, which may help (or hurt, depending on where the split is).  JoeB.

  Jerry, I am using a thin belt Harmonic damper that I got from BFE years ago.  It has spacer that goes against the slinger and the joint where the damper meets the spacer is right about where the seal lip is.  I found a double lip seal, but that was 10 years ago and I can't find my records of what it is.  If I come across it, I will post it.  Joe B.
