How hard to change rear shaft? By Doug in San Diego (Read 940 times)

Hi guys

Like many of you I read all three forums, so if you do sorry , Im going to put this on Scootdawg too

Any hoo

How hard is it to swap out the rear shaft (the one that the wheel goes on)

I have another engine (yes Im still looking) with a short rear shaft.

Of course I could use the shaft from my old engine so how hard is the job?

There's other forums!? It's not a big deal to disassemble that Doug. The Ace 150cc manual has a nice explanation with great diagrams and real pictures starting on page 49. Click on the image below to go to the manual:

This is kind of a forgotten manual but I don't know why more people don't use it; an oldie but goodie. Rich

Thanks Bashan

Looks pretty easy.

1) Do you think the gasket would have to be replaced if you opened that up?

2) It doesn't look too hard to change the final gears at that point. Have you ever done that?

I always wondered if that would be an easy way to improve performance, but I thought you needed a special gear puller.

I've never had it completely apart because I never had any issues with that area. I did take that cover off that you see in the diagram out of curiousity. It's been a while but I seem to remember things coming apart quite rapidly with out a puller of any kind. My gasket went back on no problem but the scooter was pretty new. If it was trashed you could easily make one out of the gasket sheets that you can get at the auto stores and Tractor Supply. I use the grey stuff for everything from intake manifold gaskets to oil/gas gaskets and never had a problem. Rich

I agree Rich...I love the ACE manual .. best one for drawings...

have to get that manual myself. as far as the gasket goes, if you have to have it running now, buy a gasket just in case. they are paper so it may tear. but it may not also. if it doesn't then it should be reusable and work fine. my cvt gaskets always tear and i just get rid of it, but this holds gear oil so it is needed, but on both of the ones i took apart to replace the oil seal, this gasket stayed intact.

Hey Doug, I ran into this PDF on the web today, maybe it will help. Rich
