Topic: Engine case gouged during disassembly

[Ellz10]

So PVC pipe wasn't doing the trick when trying to crack the cases, so like a complete moron I used a screwdriver and gouged the gasket surface on one of the cases only.

I'm getting ready to send a load of parts over to Cycle X in Wisconsin to have work done and my question is this:   should I send the gouged case along with the parts so they can buzz the surface smooth or is there something else I can do to remedy this?

You really can't buzz it smooth without making a depression. They don't look to bad. I would fill them with JB weld and gently smooth them to meet the surrounding surface. I don't use JB weld a lot but I think tis would be a good place for it's use. On my cases I use a fine diamond hone and gently go over the surfaces to knock down any slightly raised edges.

Let Cycle X take care if it, they know what to do....
I dont know why people do that..?
 Put the case on its side, put a 2x4 against the crank, and give it some taps.. or the rear motor mount.. ...carefully..

You cant just "buzz" it smooth, you would have to do the whole flat surface and that would destroy the main (and other) bearing clearances thus destroying the cases

This is the stuff I use for small imperfections in cases or covers. A two part high tech bonding agent with metal reinforcement material in the formula. It is good to 500F and dries steel hard in 15 mins. and can be machined, drilled etc.

I believe JB Weld has a similar product with different temp values and cure times, yet it is likely equivalent to the Tech Steel product.

Dont know whether it still exists but Devcon F was a similar product for alluminium. I last used it in 1975 so i may have the letter wrong as they made different sorts

In the trick and tips a guy showed how to split the cases using turnbuckles.  I know it's after the fact but for future reference.

When cases do not want to come apart its usually a forgotten M6 bolt.
At starter motor location, under side close to clutch cover.
