[Fot] Overheated parts

[Peter Vucinic]

Wow! That's getting a bit scary! 400F or there bouts for blue.

Would not have done the steel structure any favors at all!  We are in
'stress relieving' territory for crankshaft materials.

 

I would not be placing a bet on the components if you use them again. Best
talk to Carrillo. Whatever they recommend will go equally as well for the
crank.

You may find that they are distorted beyond use in any event.

The oil pump broke in my TR4 and roasted the bearings. The Moldex steel
crank and Carillo rods are not damaged but are now a blue color from being
overheated. The machine shop is wondering if it is ok to use them. What are
FOT thoughts? It takes 6 months to have another crank made.
