How do you get this off?!?!

2fives · 05-16-2008, 04:34 PM

So I figured out the piston on my 3.8hp Tecumseh turns but the valves don't move in and out so I have to take the whole thing apart to get at the problem, but how do you get this thing off so I can get at one of the bolts that hold the engine on (see pic below) instead of just mangling the plastic shield.

is there a seal around the centre hole with a circlip behind it

I'll have another boo, but it didn't seem like there was.

That's the blade adapter, it's just rusted on. On a new mower, they slide right off. I would thread a bolt in the crankshaft and use a gear puller to pull it off.

I thought it would come off with a puller. I tried just whacking it a few times to jar it loose but no dice. Gotta go buy a puller.

spray it with penertrating oil and leave it for a few hours before pulling it,this will make it easier to get off

Yes, be sure to soak it with penetrating oil. Not WD-40, either. Sometimes you can get them off by whacking it, but not with that plastic guard the way it is.
