hercalmighty Posted April 17, 2017 Report Posted April 17, 2017 Stupid question. I'm installing my first roundhouse swing arm. What should I torque the pinch bolts to? Thanks Sent from my VS990 using Tapatalk Quote
guns4children Posted April 17, 2017 Report Posted April 17, 2017 Tight as fuck. But not too tight. Do your nuts have the nylon on them? Quote
hercalmighty Posted April 17, 2017 Author Report Posted April 17, 2017 Yes. They have the nylon Sent from my VS990 using Tapatalk Quote
locogato11283 Posted April 17, 2017 Report Posted April 17, 2017 What bolts are you using? I'd recommend using grade 8 bolts. Quote

spurdy Posted April 18, 2017 Report Posted April 18, 2017 Are they grade 8? If not, use grade 8 bolts. Sent from my iPhone using Tapatalk Quote

hoppedupandcutdown Posted April 18, 2017 Report Posted April 18, 2017 Mine came with 12.9 grade cap screws. More better. Quote
spurdy Posted April 18, 2017 Report Posted April 18, 2017 Mine came with 12.9 grade cap screws. More better. 12.9 is a class for metric bolts and is a higher grade than a grade 8 for standard bolts. Grade 8 is similar to class 10.9. Sent from my iPhone using Tapatalk Quote
guns4children Posted April 18, 2017 Report Posted April 18, 2017 Tighten and enjoy. I don't know what type of riding you do but I've been through at least 3 chains with the bolts that came with the swinger. I dunno if they're grade 8 or not but they have a Allen head and a nylolock nut. Sent from Planned Parenthood Quote
hercalmighty Posted April 18, 2017 Author Report Posted April 18, 2017 Ok. Just looked at the bolts. They are 12.9 bolts. So just tighten the hell out of them or is there a torque I should go by. If it matters it has 4 pinch bolts. Sent from my VS990 using Tapatalk Quote

It sure if the rotation thing would work so well since, in theory, there will be no stress on the carrier due to the bearings. How else would all these extremely high hp motors not destroy JTs (and others) lightened carriers? Sent from my iPhone using Tapatalk Quote
