Mid shaft again

[Charlie K]

Is it possible to tighten the nut from the U joint to the midshaft without removing the rear swing arm. The nut on my bike came loose and is off the end Of the shaftand I was wondering if I could just put the nut back on with a ratchet through the opening that the driveshaft goes through or do I also have to remove everything including the swing arm.? Thanks in advance for any help.

I don't believe so. There's a small access port on top of swing arm but don't think it's big enough to get a wrench through. Probably best to remove it and see if there any damage to the u-joint or middle driven gear assembly.

Use this if you haven't yet referred to it.

I have resolved the problem, I took everything apart and took out the rear swingarm and replaced the original nut with a nyloc nut with red thread lock so I don’t think it’s going anywhere. Luckily for me the shaft was in good shape but the nut was destroyed

Hmmm is the original part a nyloc?

It must get pretty warm in there so could the heat affect the non metal gripper?

There are all steel nut that have a similar grip end, the name escapes me..... Aerotight self locking, and there is a lower profile variant from the same store clked self-locking (I can upload photos if you require)

Thanks but I think it would have to get pretty hot to affect it, anyway, time will tell. Also used red thread lock so I hope I’m good

It would have to run hotter than the engine oil to have a chance. Nylon lock nuts are good up to 250 degrees.
