Crank Oil Seal

[Tom Katzenberger]

Gentlemen,

I am installing the crank oil seal behind the hormonic balancer. The book states to use the J-5154-01 tool to set the seal at .005 from the bottom of
the tool. I do not have the special tool.

Is there a field method to set the seal to the desired depth, or is there a measurement from the exterior surface in which the seal should be set?

Thanks again,
Tom

Tom,

If the engine really does have only 8K mils on it, the set-back on the seal won't matter. That is an old trick for used parts to make the seal run on
a new and undamaged surface.

The tool noted is for setting the seal square over an installed crankshaft. If the timing cover is still off, just put it in on a bench.

Matt,

I was skeptical about the 8,000 miles also, but after removing the nylon gears I am positive the mileage is accurate. The gears look brand new. They
are still 43 years old and most likely brittle so I am glad I am replacing them.

With regard to the oil seal, would you hold the seal flush to the interior of the cover, the exterior or in the middle?

Thanks again,
Tom

Matt,

I held the seal to the front of the cover as the balancer had no indication of wear as you stated. I was just trying to get the seal in the most
advantages location. I wiped assembly lube for the startup. I will keep my fingers crossed for no oil leaks.

Thank you and Jim again,
Tom
