You'd be amazed just how much oil your 22R engine can lose with a leaking front crank seal, twice now I've checked engine oil level and found nothing on the stick ! this was after adding oil and driving maby 100 miles.

Except for a few cranky radiator hose clamps on my 81 2wd pickup, pulling the flywheel went real easy, it doesn't have AC or power steering so I was able to use a vise-grip chain clamp on the front (unused) pully on the Harmonic balancer to hold it while I used a length of pipe on a breaker bar to get the crankshaft pully bolt undone, the Harmonic balancer slipped right off without using a puller.

To clean the seal area, protect the crankshaft surface from damage and keep crud from entering the engine I made up a simple piece of exhaust pipe, just had to wrap it a few turns with tape and it fit snugly into the seal. using a thin wall piece of pipe means it will slip over the crankshaft without disturbing the woodruff key.






Instead of using a speedy sleeve I plan on using a seal from a 1994 22R/RE, part # 90311-45014, which measures 7mm thick as compared to my original seal at 11mm. this should reposition the sealing surface away from the groove worn into the pully hub.
