problems with yet another 89

Dart - Textbook seals story / scenario, Amigo - sorry to say !!!

Noones done a writeup per sec, but Dave has a ton of knowledge on the procedure (which CAN be done right in the cart, believe it or not) ... Basically you pull the drive clutch, pull the engine housing/fan/flywheel, go back in to the air conditioning (cleaning up the inevitable bad language you've adopted while pulling the flywheel), grab a beer, then start the next day by weaseling the seals out, cleaning up the housing for the new ones, put the new ones in with a little loctite, then reverse the procedure.

You'll need a steering wheel puller and a couple of long m6 bolts along with a can of PB to pull the flywheel, for the clutch you'll either need to buy, borrow, or fabricate a clutch remover (easily searched here in the threads, not tooo hard) and the rest is simple hand tools and beer. How MUCH beer is entirely up to you.

Fair enough. I race lawnmowers so i am no stranger to removing the stock flywheels and tearing into these small flat head engines and OHV engines. I have a puller from my old quad that i think will work. I guess i am just gonna look into a rebuild if i am going that far. The engine will just come out. I am sure it has to be easier when its out.

thats a big 10-4 (removing the engine to do it easier) ... as long as the puller has 2 slots across from each other you should be fine (these flywheels only have 2 threaded holes for the puller) - as to the rebuild, your call, but these lower ends don't generally wear too bad as long as they're oiling correctly (or the proper premix run), I'd do a compression test to figure out if you need a top end, generally 120-ish is still sweet, anything between 100-110 is iffy and 90-ish and down is either not running or about to be ...

Oh, and you can pull the engine and clutch together and pull the clutch later (obviously) - that makes it a *little* easier to get at it but it's almost a lighter chore without the engine sliding around, etc (depends on how good of a "helper" you have)

Good deal. Thanks for the info. I plan on heading home later and digging into it and seeing what i can find. I am gonna start with a compression test and then go from there. I fear something might be hurt internally though.

Dart i'm pulling mine out , have alreadt cleaned an end of workshop bench to get ready for it ,
I was into mower racing about 4 years ago but the track moved from 20 miles away to 185 miles away and I sort of dropped out , was running S/P class all aluminum flat head block with a 15.5 ohv crank and a 17 hp rod and piston and one of don's cams from up in Dakota , with all that engine work mine was good enough to pull a 3rd or 4th . I think I could have done better if there wasn't 275 pounds in the seat .

Update - got the flywheel off and found seal completely out of the block and just rolling around on the shaft , once the engine was/is out I can see the one behind the clutch and it looks fine, not even any grease/oil build up around shaft or block .

Hey Goat,

Hope you're still planning on replacing that clutch seal too. Getting the clutch off really isn't that hard, and can be done with some easily obtainable parts (1/2" fine thread bolt, rod or other bolt).

With these seals, they're rubber and do wear down. As long as you got the engine out, might as well do it.

Also, don't forget to clean out where the seal seats, and throw a little loctite blue in there - makes it harder to pop it out again.
