Kiaora, I am assembling my 292 engine and I am wondering about the thin locking nuts that screw on top of the Bigend bolt nut. I have tightened the nuts to 45ftlb. Do I nreally need to reinstall the thin spring type hexagonal locking nut. OK I'll confess, I lost one and cannot get one to replace it. So is it ok to reuse the ones that I have or do I really need them at all? and what torque setting should they be tightened to.
