Re: 1958 Scott-Atwater
It was very fulfilling to free a seized motor
I know the feeling of succses
and the pain of failure
With the old Atwater and the steering wheel type puller you want to get set up evenly with as much pressure on it as you can, then maybe a good rap or two with a 2Lb hammer on the puller, don't over do it or you bend the puller. then add some more pressure if you can....this may take a day or two??? if its that stuck, but stay with it, I know everybody has there favorite penatrating oil but after hearing about Kroil for a few years and of course being the doubting Thomas I am I finally bought a spray can of it, WoW....its the best IMHO she will get down there in that tapper on the crank no doubt, in recent weeks I have pullled 4 Atwater flywheels and two of them had not been off since 1946... they were rusted on but finally gave in to my heavy overhanded ways...hehehe
I suspect the flywheel bolt to be stripped
your are talking about the crank threads right?
On the flywheel nut best thing to do is chase the threads on the crank with a female chase ( you may have to go meteric ) and try and find a deeper grade 8 nut with the same thread size and then a washer and a dab of lock tight maybe?? or some 3m gasket sealer on the threads when it goes back on, I have seen a bunch of these cranks that looked stripped while I was searching for parts and they most all had nylon lock nuts & washers???, not sure if thats how I would go but thats what I have seen, I have fixed several Tecumseh crank threads with my method.
....its all fixable in my Opine....
F_R and the other vintage experts would know better than me on this subject as I'm just a padawan learner myself although I been beating around the scrap heep for 40 years ...lol
PS, watch out for horror frieght pullers, they will break bend and bust in your face, best to borrow a good one from the auto parts place.
some said a smack to the top edge of the flywheel helped distort the tapper enough under pressure to pop it but I have never had the guts to try, cutting one off will be a big chore when it comes to the steel female insert part. maybe best to just invest in a used powerhead
