tiny crack in BEC casing
Hi there,
I have a gsxr1100wp in my Phoenix. The engine has a bit of a history that includes a home in a racing sidecar outfit.
I've been losing a little oil for a while so thought I'd have a look.
2 of the 3 oil leaks were easy repairs (slightly loose oil pressure switch, and clutch cover).
The third is more challenging. It appears that at some point a hole in the casing has been repaired. It is around the clutch so either and exploding
clutch, or the oil pump take-off gear has burst (they can do this if you try to drive the engine backwards, like after a spin).
Their is a tiny weep from where this repair has been made. Any ideas on the best method to stop the leak?
I was thinking of cleaning and roughing up the case (to bare metal) and then patching with a 1p sized bit of aluminium and some JB weld. It
isn't anywhere visible and the engine has no real resale value so I only need it to be functional. I can't weld aluminium and I'd
prefer not to bother to open up the whole engine.
Any thoughts appreciated,
Matt

That should work as long as the oil is cleaned off before the patch goes on.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

You could try this - http://durafix.co.uk/
I've stuck some bits of ally together and reapired a couple of castings with it. Make sure you practice first before you use it. It is quite
' strange' to use and won't leave the prettiest repair but it certainly works.
Cheers
Dave

Providing the casing isn't subject to stress I would be inclined to hold to plate to the casing with two or even four short self-tappers.
Clean and score the casing, whack on some JB, screw the plate over that and seal the edges with JB - simples.
That's worked for me on both car and bike engines - it's probably belt & braces but you don't really want to have to do it a
second time.
HTH.
Cheers, Pewe10

Thanks chaps.
I've used that durafix stuff before with some success, but I wouldn't be able to get enough heat into it, and also don't fancy
stripping it all down.
Probably stick with the JB and those tips.
Thanks,
Matt
