I'm at that point in my engine rebuild where I need to toque up the starter dog bolt and the flywheel nut.
Tomorrow I will be tightening up the big end bolts
I'm using a Phoenix pressure fed crank, and Renault 4 rods.
Can anyone please help me with the required torque settings for these fasteners?
Google has suggested between 25 and 30 ft-lbs for the rods.
Phoenix has come back saying he thinks 100 ft-lbs may be correct for the flywheel nut.
I have no answers for the starter dog bolt, nor any idea if the above figures are correct.
Its been a while since I have been A7 Friends and its great to see the more modern forum bulletin board in use.
Looking forward to some informed replies

Can't help you with the R4 rods but my flywheel is tightened to "very bloody tight". My torque wrench reads up to 150ftlb and it's tighter than that. I subscribe to the "leave off the locking tab washer" school of thought because it's softer than the nut or flywheel and may "give". Just Loctite.
I've never seen a torque figure for the starter dog but again "very tight" works for me. I use a lock washer here.

Thanks Charles
I too don't like the idea of tab-washers. I do use 243 Loctite to act as a secondary retention method on important fasteners.
Useful to know that you tighten above 150 ft-lbs.
If any ones else has some figures I would appreciate this.
Cheers
