I'm working on another problem that is indicating I may have a top crank shaft seal leaking. I'm considering changing this if it's as easy as I believe?
- remove flywheel + Stator and trigger.
- Pierce the metal on the old seal and pry out/insert screw in holes to pull up.
- Clean, etc. align, lube and press in with a suitable socket or custom made wood mandrel.

I've done many of these types of seal before - I just want to be sure the seal is removable without splitting the crankcase.. Pics or seal seams to indicate a pull out and push in style (i.e. no trapped lip).

Thanks All 1996 60 hp merc.

Thanks All!

IFirst Thanks for the response! Just in case it is the seal, I'd like to know if it's changeable anyways,

I'll start a new thread called Cannot Idle under 1500 - 1800 RPMs To better track the issue. Please take a look.

OH Also - it's a 1996 MErc not 1986

Has anyone had a failed top crankcase seal on a similar motor - or change one??

Thanks

Thought I had once, but no. Easy enough to change it.

Thanks Jeff. Just concerned if I start to pull it and it's trapped under a lip (i.e. you must split the case) and I damage it I'd be screwed. IF I can pry pull it out easy I'll change it.

Use a couple of sheet metal screws and pull gently, a little at a time, on each.

Solved - Seal was not trapped - easily pulled and changed when flywheel removed. Thanks All! SteveC
