Engine refresh – day 3

Today was all about the front crankshaft seal. It wasn’t leaking, but it was accessible with the engine out, so why not? Well… one could argue: don’t fix it if it ain’t broke, that’s why not.

First step was to get the crankshaft harmonic balancer bolt out. This bolt is torqued to 150 lb/ft… and then turned another 180 degrees. It’s in there tight… so tight that the force actually stretches the bolt. Getting the bolt out took me about ten minutes of straining, spraying penetrating oil and an air impact gun.

Since it wasn’t leaking it was a bit of a pain to pull out. By the time I realized I should have left well enough alone, I had already beat up the front of the seal, so it had to come out. With John’s help the seal finally came loose. Putting the new seal in was simply a matter of finding the right tool to seat the seal (which, when you don’t have a seal tool, the right tool is a 36mm Craftsman socket).
