: I just cleaned up my fly wheel housing and found some cracks inunexpected places.
: I have two cracks approx. 1 1/2" long extending through the mounting holes at the 3 and 9 o'clock position where it bolts to the engine.I have heard that the upper two "ears" where the accelerator bracket bolts up is the common place for cracks (none here).
: Can someone offer advice on options? Welding, metal stiching, etc.?
: Thanks, Benny

Benny --
I just went through all of this a few months back.There should be some postings on the Board, as of the Spring of this year.If you decide to repair, which I would do since you don't plan on pulling this apart any time soon, there is a very definite procedure to follow.Cast iron tends to be difficult to work with.However, if you gradually heat up the housing to some 400 degrees over a period of 4-6 hours, you can then stick weld the cracks (bronze, if you prefer).Heat should then be removed slowly over a period of two hours.A rapid cooldown will create more cracks.
If you are not doing this yourself, I would mention to whomever is doing your work to use this gradualistic approach.
Good luck.
Regards,
Gordon
