Any ideas on this one? Repairs...

I am looking for opinions regarding my two rear axle bolts. They each broke once each on my last two rides. I have had this problem before on the rear axles. I replaced the axles and bearings on the rear and all the chains all the way around. I had cup washers for Richards Relics welded on the sprocket sleeves and am now running a longer bolt as well as having new axels. It was working well until now. Just get in the muck and pow! pow! they break.Are there certain replacement bolts to avoid? What if I used some kind of pin instead, like as on a trailer hitch?

I was told to only use bolts that are only threaded below the axle so the part of the bolt that passes through the axle is non-threaded. What kind of bolts are breaking in your machine?

good call Cole, here are a few threads on body bound bolts: http://www.6x6world.com/forums/gener...ound-bolt.html

i use grade 8 and so far haven't had an issue (knock on wood)

You might try a shoulder bolt that is long enough for the shoulder to pass all the way through the sleeve. As Evil said the threaded area of the bolt is weaker than the shoulder area. I think that a grade 5 is recommended for these because they have a greater shear strength than a grade 8 which has a stronger tensil strength. The threaded part can be trimmed if it protrudes too far through the axle, you only need enough to get a couple threads past full nut.

yeah, the bolts that are shearing off are long enough to not ride on thread so I got that one out of the way. Trial and error .

Im not sure of the bolt grade, but the bolts come from the bin at NAPA (crAPA). I have broke other types of bolts on the same two axels before, also.

I am trying to avoid the holes in my axels getting wallowed out with stress, too, so now this thing has me spooked to ride again.

Have you tried stainless bolts.

crAPA Now that's funny!!

When you say they break when you get in the muck, does this mean that you are gassin' on it and they break? If so, it could be that the tires are spinning and suddenly catch traction and this pops them. Irresistable force meets immoveable object ...

I bet if they had seen this one they would have called it something other than NAPA!!! Like we call O'Reilly's Oh Really's 'cause when you drive 20 miles to return a part you JUST got home with and walk up to the person you JUST bought it from and say "I just bought this here and it's tha wrong part" what do they always seem to say.... Oh Really...
