Honda XLR125 Clutch plate change. Help?

[Inithra]

Hi, my bike is actually a Gilera, but my research seems to suggest it has the above Honda engine.

I've bought the clutch plates, and borrowed the castellated tool thing from a local bike garage, but can't seem to "lock off" the clutch in order to actually undo the nut. The garage just use an impact driver, but I don't have one, so the clutch just turns and moves the back wheel. I've already broken the "spider basket" by trying to brace it, can anyone tell me either the correct way, or an easy workaround?

The garage did have another tool, or part of the same one, but because they just use an impact driver, they didn't know how it worked!

Many Thanks

The way I do it is too put it on the side stand with the rear wheel firmly on the floor, sit on the bike with the wrench on the nut, and put full pressure on the rear brake. That should hold it enough to release the nut.

We did try that, but even then the back wheel and whole bike moved, enough to unbalance the bike (almost pushed it off the sidestand, and I only had one foot on the floor because my brother was on my right trying to undo the nut).

In case we are doing it wrong - does the thread undo toward the rear or front of the bike?

I considered shocking it, by whamming the handle of the wrench, but it just slipped off.

it should be a standard thread so anti clockwise to release it,have you checked to make sure that there isnt a locking washer behind the nut with one of the tabs bent over into the castle section of the nut??

Improvise a long handle for the wrench with some tube or something, or just wheel it to your garage that let you borrow the tools and see if they can just quickly put the rattle gun on it for you
