Splitting cases on 350x

[DDQ]

I am about to start splitting the cases on my 350x to see why 2nd gear is slipping. With the motor on the bench I can see that a case has been welded. Will it be safe to reuse these cases or should I buy another set?

I would buy a new one

If it looked good to me and didn't leak I'd run it. Definitely check the mating surfaces on a surface plate though.

Thanks.


I have run into a problem. I have been following the manual for the tear down. I put an impact wrench on the primary gear nut and held the gear with a rag and my hand. The nut spins and spins but will not come off. What is going on?

[fabiodriven]

I can only guess it's stripped. That's bad news.

I may have messed up. I missed this part in the manual. Can anyone tell me what it means to unsteak the lock washer? The washer behind the nut looks flat.

[fabiodriven]

The lock washer is peened over one or more of the flat surfaces of the nut to prevent the nut from backing off. I don't know how you would have the nut spinning if you didn't move the lock washer out of the way.

Edit- it says to grind the staked lock nut, not lock washer. I'm beyond the point of experience now and someone else will be able to help you.

There is no part of the washer peeled over the nut. Tje washer is very thick.

Another pic.

Its the nut itself, the outer edge is pushed into the slot on the shaft. Look around yours you’ll see it. Still not good news though if yours is stripped. Spin it (nut) until it lines up w/slot and bend it out a little (small pic or flat driver)
Thats all i got for you (not a 350x guy)

Thanks for the pic shep. I was very confused that the manual says to use a drill or grinder. Ill try to knock that dimple out. If the nut still will not come off I guess I will have to cut it off?

[fabiodriven]

I would assume you may have to cut it at this point. Sounds like you may have a new challenge to deal with once you do get it off unfortunately.

[Shep1970]

I’d put the power tools away (do it by hand) hope that the nut stripped and not the shaft. Possibly and i really don’t want to suggest it but “visegrips” with outward pressure while turning “may” catch but ya i dont really want to suggest that...
At this point drill the nut horizontally with the shaft “not near threads” coal chisel and split it
I’ll be watching good luck

Wait until tomorrow you’ll have better suggestions

[DDQ]

I cut it off and here is what I am looking at. Any chance I can fix this with a die?

[ironchop]

Yeah a die or a thread file would clean that up enough to use
