front shock lock collars are seized up

[lmt0705]

tried adjusting my front shocks yesterday and the aluminum collar must have galled up the threads on the shock. I can see some damaged threads on the left shock. what can I do to fix them?

That doesn't make any sense. The collar has to move so the spring can be compressed or decompressed to adjust front ride height and spring action.

Mine are stuck too, but I haven't gotten serious yet about trying to free them up. If anyone else has gone through this exercise, glad to hear some advice.

Um, no. You might be thinking of the stopper at the top of the shock thread that some have. The collars must be loosened before the spring tension can be changed. They are on there pretty tight from factory. I had to use a flathead screwdriver and hammer. Place the flathead in one of the grooves of the collar and tap the collar in the direction to spin it loose. Make sure you are just tapping on the collar groove and not hitting the spring nut. Takes a couple good taps to get it loose and then moves by hand. When done adjusting your spring use the flathead again to tap it tight.

If you move both at the same time, collar and spring nut,(which is possible if your tough enough and use a wrench) you will strip the threads on the shock.

shock

If it is a front shock jack that side off the ground warm the threaded ring up it will move. If it is the rear shock jack up the sled from the rear pumper track off the ground and try and losten the lock ring call me at 920-810-4430 I will taulk you through it

it is the front shock and im aware of how its supposed to loosen but I have a pulled thread on the shock and its stuck. I tried heating it to the point that I was getting worried about popping the shock. im thinking it will have to be repaired or replaced

Had this happen to me, either the shock body threads or the aluminum adjustment collar are pooched. I was lucky, the shock threads were ok. I removed the seized aluminum nut by carefully making a diagonal cut with a fine hacksaw at abt 45 degree angle to the shock. When you get down close to the shock threads, stop and then take a cold chisel and tap down in the saw cut to spread it apart, if you've sawn deep enought the aluminum nut will break apart and separate off the shock body. Clean up the shock threads of any remaining aluminum pick up and work the steel adjuster up and down over the shock body threads to "chase" them clear. I bought a used aluminum nut from a shock rebuilder for abt $10, otherwise, I don't think Yamaha sells just the nut. Good luck.

I have the same problem with a cross threaded collar nut. I was thinking about using a drummel tool to cut it off. Glad I'm not the only one that had to do this. Now I just need to find a used aluminum nut like you did.
