Hello,

I have a crashed Saito 91 engine, the crankcase at the back has
a crack.

I am not sure if the crank is bent, there is a little friction when it
is turned and it can do a full turn. The bearing are probably
crushed which could be causing this.

What is the best way to check if the crank is bent ?

I see in the previous post, guys are talking about forcing it back straight. What are the implications ?

Worse case I have to buy crank, bearings, crankcase, carb.
Best cast I would not have to buy the crank.

The bearings are NTN type, would these be the same which are
sold by NTN distributors for auto/machine etc ?

Thanks,

L
