    Fleetwin – I ended up doing just about what you described. I first pulled the rubber portion of the seal out leaving just the metal case. My seal puller was just tearing through the face of the case so I grabbed the top face with some pliers and pulled it inward toward the center of the hole, thereby collapsing the case inward away from the bore in the housing. After I got a small space between the bore and the seal case, I applied a little heat from the torch and some PB Blaster around the bore edge. After 30 minutes or so, gave it a little tug with the seal puller and it came right out. No damage to the housing, bore hole or bushing. Seal ended up being pretty torn up but who cares – it’s out!

    Good work! Dave Bono made me a few seal pullers that work with a two piece collet that fits under the upper metal seal housing once the rubber is removed. There is a threaded bolt that draws the seal up into a cylinder….Works well, but even this sometime takes a few tries because the darn seal housing just bends upward allowing the collet to pop out….
    The only thing I am convinced of is that the slide hammer methods usually just end up bending the lip upwards until you have nothing left to work with…
    Those 10hp upper bushing seal assemblies are getting harder/more expensive to find, so I’m glad you saved it successfully…

    I’ve done a bazillion seal removals as tubs shows above. Job is much easier done with a small cape chisel. Most people nowadays don’t even know what a cape chisel is

    You can more or less duplicate it by re-grinding the tip on a round drift punch..

    You want real slippery… try Dupont Teflon spray for snow blowers it just soaks deep in cracks and would probably get the seal to be removed without to much pain

    the stuff is made so the snow exits the snowblower quicker and prevent ice from sticking … (probably not available in Florida 🙂 ) but Amazon has it

    OK, I’m not afraid to show my ignorance….That tool sure looks effective, but how do you use it on the seals???

    As with any job, start by first standing back and evaluating the situation. Different seals, different installations etc. But whatever the case, the general procedure is to first attack the top of the seal at it’s outer rim, angling the cape chisel’s rounded cutting edge toward the center, and go around it like a can opener to cut the top off. Then going downward attack the outer shell of the seal to fold it inward as tubs is doing in his picture with a pointy punch. The rounded cape chisel is less likely to damage the seal bore in the part. Once it is folded inward it will almost fall out.

    I started on the gearcase reseal job today only to find a crack in the seal housing. It’s not something that could be repaired with epoxy or JB Weld so unfortunately I’m on the search for a replacement housing, OMC part #377186. I put an ad over in the Classifieds but thought I’d post a note here as well. I know these plates can be hard to come by but if anybody has one they’d be willing to sell, contact me at rockportbob19@gmail.com.
