Hartebreak Posted June 17, 2018 #1 Posted June 17, 2018 Anyone happen to know the size and the thread pitch of the swingarm pivot bolt ? I cannot seem to locate anything online.
bongobobny Posted June 17, 2018 #2 Posted June 17, 2018 It's metric, M10 I believe. Not sure of the pitch, but if you buy a nut of the same pitch you're in like Flint! From what I remember it is a through bolt with a nut... Maybe someone has a spare one laying around that they will ship you.

Im actually building the venture into a trike (mad max style) and am creating a swingarm to connect the rear differential. I want to use the OEM pivot location, but the OEM pivot bolts wont work for what I need, so I will be buying some bolts to use, just need to know what size they are. I took the lock nut with me to Fastenal and they didnt have anything....
RDawson Posted June 17, 2018 #4 Posted June 17, 2018 If you're replacing it anyway the thread pitch shouldn't matter. Find the right shaft size and get a lock nut to fit. I'd go with a hardened bolt.

I'd go with a hardened bolt. Yea, I will be using grade 8 bolts. I was hoping to be able to thread a bolt directly into the frame, but youre right, I could just drill out the existing threads and do a bolt and lock nut combo.
RDawson Posted June 17, 2018 #6 Posted June 17, 2018 Ah I didn't realize the frame was threaded. Most good hardware stores here have a size/thread gauge if you take a bolt.
djh3 Posted June 18, 2018 #7 Posted June 18, 2018 Usually the bolt is 2mm smaller than the wrench that fits. So if a 12mm wrench a 10mm bolt. If its allen head all bets are off. Something like that will probably be a coarser pitch like a 1.25 (fine) or maybe 1.50 In a 10mm. Metric fasteners grade strength go like 8.8 which equals a grade 5 SAE, so for like a grade 8 you need 10.9
