Default Can't get drive washer off Saito 91

I have a Saito 91 which is need of bearings. A friend and I have been trying hard to get the drive washer off. We've used a puller, heated it, whacked it (not a metal hammer) and it just won't budge. I'm afraid of bending the crank. Any other ideas of how to get this thing off? The engine is about 12 years old and has never been taken apart.

Thanks,
Chris

Wow, I am surprised the puller doesn't get it! All I can think of that's left, is cutting it off. You can use a nut splitter, or very carefully a Dremel.

Get some of this stuff at Napa Auto....trust me, it works. Let it set for
awhile....(an hour) ....spray more on every 15 mins. It will dissolve the
dried grease and cut through rust.

It works on tough to remove wristpins too....cutting through the shellac.

Chris:

Yours is a common problem, you might as well break down and buy a decent puller. Check the thread here:

Post five shows the Snap-On CG-240 in use on a Saito, post 12 shows the Snap-On catalogue page.

Alternately many auto parts houses rent/lend tools. Perhaps you could visit your local auto parts store, use one of their pullers, and be on your way.

I made me a puller for such a job. I had a problem with a Super Tiger 90. This really worked.
Do you need to rent this for a very reasonable price?

The little one is for a 40 size engine and the big one is for the 90 size engine.

I finally got it off with my puller. The drive washer would not come loose from the brass collet. I had to drag them all the way off the crankshaft together. It pulled hard all the way off. I would tighten the puller as much as I could and then hit the end of the puller with a hammer. The shaft is still straight (luckily) but the puller has seen better days. I'll tackle the bearings tomorrow. The crankshaft came right out of the case.

Thanks,
Chris
