They are probably all the same but this one imparticular is 06 mastiff . I'm putting a new final or main drive belt on I'm down to separating the frame. Now where it separates is that Allen head a left hand thread..I don't want to break it
That is the proper way correct. I also see on that same bolt there is a large sleeve or something that's round that has 2 flat sides where a wrench could possibly fit. Would that possibly be the key to separating the frame. I don't have a service Manuel but it is on my list. Ty for any help anyone can provide

I’m not 100% sure but I was thinking on the ‘06 mastiff you didn’t need to take the rear swing arm apart to get the drive belt off…. Just remove the rear wheel. Now LSD I was thinking was the opposite. You have to remove the swing arm at least on my Vintage Sport.

OLD Thread, but I'm wondering if anyone has ever had the pleasure of changing a belt on a 05-07 mastiff or bulldog?
I sure haven’t Pat, but it can’t be as bad as changing out a LSD belt. I would certainly think Knothead would have the information you are looking for. Pretty sure Daves mastiff is a RSD. Give him a call.

It can definitely be tricky without the manual in front of you. From what I remember, that sleeve with the flat sides is meant to hold things steady while you back out the Allen, so using a wrench there helps keep it from spinning. And yes, the rear wheel has to come off to make life easier. If you’re worried about thread direction, I’d double-check with Knothead or someone who’s done a Mastiff belt swap recently; better safe than snapping a bolt.

Will do Thanks Mick, I thought I would start here and see who chimes in. I called Gates and they don't make that belt anymore and it's a 1 1/8 X 133 teeth and the Gates CS guy I talked to has yet to make it to the CS classes. :(
I have the wheel off for a new tire and the belt is 20 years old so I thought it could use a new one.

I do have a manual and always us it as the memory is very good but also very short. Have you replaced a belt on your Bike?
