Crack inside cover

[jsmith1107]

I took off the cover on my CL77 and noticed this slight crack inside---will this affect anything?

Sorry about the fuzzy picture.

Thanks,
Jeff

Hello Jeff,
If you follow that casting downward it ends at a transmission bushing that is "located" by a dowell pin between it & the upper case.
The crack may have been caused by a wrong length pin when the cases were joined.
I believe the oil feed for that bushing is from the lower case which means that there should no problem regarding oil leaks, however there could be a misalignment of the bushing & gear shaft.
The only way to determine the cause would be to split the cases & correct the problems-------

I feel like Mr. Dumas!! I should have asked:
1. Is this a running motor?
2. did it leak oil?
3. was the shiftIng ok?

Your answers would indicate a plan of action.

Thanks for the response. I am restoring the bike and happened to find this when I opened the case up. I have never had this engine running so can't really tell you an answer for any of those questions. If a person gets a new upper crank cover for that, they usually have different numbers on them, how do you deal with that in regards to title?

I believe they go by the frame number for the title don't they? Chime in gentlemen

Hard to tell from the picture. Is this for sure a crack ? Or possibly a casting flaw. The reason I ask is the first time I opened up one of mine I was sure it was cracked, but what I was seeing was casting flaws. (FWIW I also have discovered cracks.)
