Talk about blind yourself with science! I bit the bullet and bought a set of ARP conrod bolts which cost an arm and both legs, and the piggin nuts were EXTRA!!
Come to fit them this morning, so went on the ARP web site to get the relevant info., as there were no fitting instructions re lubrication etc., in the kit. Obviously, I don't want to screw up on this but I found the ARP site to be pretty useless regarding the fitting of motorcycle bolts, apart from a catalogue of wondrous features of said bolts and the promotion of their super special lube.
They do give the three options i.e. Stretch, torque and angular measurement and mention progressive tightening. Draganfly state these bolts should be tightened to 28 lbs.ft. I can probably get close to this with my uncalibrated and very old torque wrench and as a double check, I can measure the stretch after applying torque, which would be great if I could find out what the stretch should be! Alternatively, I could just do what I've been doing for years on a fair number and variety of engines, and just tighten the bloody things up. I won't, of course, I will torque them up progressively and equally, and hope for the best!
