Really? I'll try that. But either way, the crank will be magnafluxed then ground, mircopolished, shot peened and balanced, and a microsleve installed on the rear of the crank for the rear main seal. I have another crank for my customer if this one is unusable.
Yup really. Old racer's trick from way back in the day...
Also, are you going to have the processes done in that order to the crank?
(I would hope not)

I think we will polish it first, then balance it, then grind it. :crazy1:
No, JK, I'll let the machine shop figure it out. I pay other people to get that done right.
Depends on how far U/S it is Aaron, Toyota's hardening isn't very deep I had to have mine nitrided to get it hard again.
I hear that IJ. One time I had a .010" under crank that needed to be ground again and the machinist said that .020" would be pushing it and I should bring him another crank.
You were right, copper did rub off on that crank. I checked it with a micrometer and it is .040" smaller then all the rest! Its in the trash now.

dont ever say that around a 7M, it will bite you in the ass..T701jz said:

LOL.....Hey Aaron I've pretty much replace all the old parts on this engine just so I can say go 1J. Daily driven, 1.5 bar, and OH yeah the SCL worked (140mph). LMK when you wanna hang out again.
Remember I got connection (RND) up in no time.

140! nice. I just gotta stick up for the 7m cause even with all the headaches I still love it. The 1j is nice, better design obviously, but my 1j has a turbo going out, a miss under boost and knocking sound at startup. My 7m on the other hand, gets flogged daily at 18-20psi and has not had any problems since it was CORRECTLY built.
