M200 breakage

[Bill Edgeworth]

Thinking about it more I would agree with what Bob and Mark both said. With the 60 foot you had the trans and drive shaft did not see a huge amount of torque. And I assume from what you said it did not shake or shudder on launch. It didn’t happen until the trans was in drive and starting to get up in RPM.
So probably something driveshaft related. The one thing I would check on the remnants of your transmission is the tail shaft bushing to make sure the yoke was not super sloppy in it. Could your drive shaft have been bent or dented? or overall length or yoke length a little short? Or touching drive shaft loop?
When Jim works on it you may want to also consider a roller bearing in the tail shaft.
Is that Peter Legg’s old car?
Are you going to have it back together for Bosie?

Bill, it was smooth with no shake. The driveshaft was perfect length for sure, u-joints were good with fresh grease. The tailshaft looks ok, other than the seal has a slight bend when the yolk came flying out. The shaft looked good with no dents or any other signs of damage. Not touching the loop either. Could the shaft just have failed? seems rare to me that a shaft would twist and break like that.

It is Peter's old car, its not going to be back together for Boise now, all plans have changed, hoping to be ready for Mission.

also guys, I am using solid motor mounts along with the poly trans mount. so strap is not gonna do anything. Are the solid mounts not a good idea?

Grant,
I will e-mail you, thanks
