evinrude 5.5 gearcase oil seal puller

[John Gengler]

I need to pull the oil seal from the gearcase head & bearing assembly on an Evinrude Fisherman 1962 5.5 hp motor. I don’t have the bridge & bearing puller tools which cost three times more than the assembly itself. My question is: are there other ways to get that seal out without damaging the assembly?

If this is your gearcase, I don’t see anything that requires special tools.
Is yours gear case different?

Prepare to be boarded!

That is my motor. Part 57 is the oil seal. It is embedded in Part 56, the head & bearing assembly. The left edge of the assembly is tapered. The right edge of the assembly has a 1/16″ ridge that might serve as a landing point for a puller tube.

I can fit a long screwdriver onto the back of the seal, but I don’t want to scratch up the inside of the assembly.

Use a seal puller to gently pry it out. Like this :

Ok. Thanks, lindy46. I have one but I didn’t know if it would do the job.

The only problem with using a puller like the one suggested is it’s very easy to break a piece out of the carrier where the seal sits.  The carrier doesn’t like being pried against and is made of a brittle cast aluminum which tends to break instead of bend.

‘Gently’ is the magic word.  Supporting the outside of the carrier with a hose clamp might help to.  Without the dedicated OMC puller, cutting the old seal out using a lathe would be the best option.

The hook-type seal puller worked fine.  I put the carrier in a wood-sided vise to hold it. I did not rest the rocker part of the puller against the carrier to keep from damaging the edges. It took a while using very gentle pulls, but it came out eventually.

Good work!  This is a frustrating operation for sure.  Using a puller like the one pictured requires doing exactly what you did, using an alternate surface such as the vice to rest the puller on.  Like Bill says, resting that puller on the delicate aluminum seal housing will trash it for sure.  Glad you got it out relatively quickly.
