Re: Rear bag bolt sizes?
3/8" X4" make sure it's grade 8. And the washer you see in that thread is from a harmonic balancer....i got a small thin washer to capture the bolt and a thicker one to give it some stability to create the same effect.

Re: Rear bag bolt sizes?
The top should be 3/8 as well....believe they are the same size...Take the bag with you and you can verify it...(or test at home w/ a 3/8" bolt...probably only need to be 2" or so on top I'd imagine but haven't gotten to that point on mine...maybe someone else will chime in...

Re: Rear bag bolt sizes?
2 Inch for top grade 8 will work. Are you mounting bag directly to frame or plate then frame?

Re: Rear bag bolt sizes?
mounting them directly to the frame, well, that little plate that the spring used to bolt to thats riveted on the frame. lowes wouldnt carry a harmonic balancer washer though right? could just a big washer work, or a few big washers from lowes?

Re: Rear bag bolt sizes?
Just get the thickest wash they have that will fit the bolt..

Re: Rear bag bolt sizes?
i just got back and got all the grade 8 bolts. they didnt have grade 8 lock nuts so i got steel ones along with fender washers for the bottom bag bolt and grade 8 washers for the top bag bolts. could i reuse the spring bolt washers instead of the ones i got from lowes? they look pretty good after 42 years, the ones from lowes look pretty good too but was just wondering.

Re: Rear bag bolt sizes?
one more thing, what did you guys use to drill the fitting hole in the frame? i bought a 3/4" drill bit, too small. i bought a step drill bit that goes up to like 1 an 3/8 or something like that but the bit is getting stuck and spinning free without cutting metal. seemed like it smoothed that step on the drill bit now, this is getting ridiculous.
i sliced my arm and nearly broke my pinky finger now, lol. any ideas of something easier?

Re: Rear bag bolt sizes?

Re: Rear bag bolt sizes?
grade 8 is overdoing it. Everyone likes to hear "grade 8" but you would probably never break a grade 2.
nothing wrong with using grade 8 though. but its certainly not a necessity, nothings going to break without it. If it did then you have problems in the deisgn or install that makes the bag pull against the bolt. |
