Ahhhhhh! Broken Crank Case!
Posted 30 April 2012 - 01:36 AM
So anyways, I get a call from the mech, saying that when he went to undo to sump plug the crank case broke off, thats right, it was overtight and when he "undid it" not only did the plug come out, some caseing came with it.
Wow. I havent seen it yet, but he thinks it can be welded back... what do you think about that?
If i do have to replace, now im reading they are a matched set, and ill need both sides?! cheapest I can find new is 600+ pre delivery and 400 delivered for the pair.
Anyone got a crankcase for sale in aus???

A good welder can fix it with no problem but I would have the engine tore down and let the welder have the bare cases to weld. Clean [ no oil ] is the trick to a good weld job.
It isn't that big of a deal, if you did the engine tear-down and rebuild yourself it's a very cheap fix, new seals,cost of the welding.

Maybe Ballards has one laying around or can find you one cheaper.

They probably could have tried warming up the sump plug? Are you from down south (Melb) They probably reefed on it when it was cold as?
All sorts of weird & wonderful things go on in mechanical workshops all over the place, Maybe the apprentice had a rattle gun on it trying to undo it the wrong way? I personally have never paid a mechanic for any work because I know that a lot of them are butchers
Have you ever been in a bike shop & heard them revving the crap out of bikes? I have & felt sorry for who ever owned it
An expensive service that one? Maybe they are going broke and need more jobs to do?
Save yourself some money & do the services yourself, + you can use better quality stuff (than a workshop uses) for the services since you are not paying labour
Just about every part of servicing only takes 10 - 20 minutes, Do it bit by bit, Even adjusting valve clearance only takes 20 minutes or so once you have done it a few times, Changing oil, Spark plugs or fork oil etc only takes stuff all time to do

personally I would replace every bearing in the case, you gotta slide hammer them out to remove them, not good for the bearings

Engine is coming out... they are going to see if it can be welded without breaking the engine down, I'm happy with this as the mating surface has not been broken. I guess its like pluging a hole?
Bolt is still stuck in the thread, so will have to see what its like too...
May not be as bad as I thought.

Threre are several methods for getting a stuck plug out, any mechanic that "knows his stuff" would not have used excessive force and broken the plug.
