Author Topic: F%$#@kken front sprocket!! (Read 387 times)

Went today to collect my new front sprocket. Well, rushed home to put it on and realised I don't have a 32mm socket to loosen the nut!

Borrowed one from the neighbor but I could not loosed the $#cker! Looked in the workshop manual and saw that this nut is torqued to 132Nm! :shock:
My socket handle was just to short to give me enough leverage to undo the nut. Anyway, I've got this 2.5 ft BritTool torque wrench that cost me $$$ a few years ago. That did the trick and the nut came off. Compared the old and new sprocket and the splines are different! :x I will have to take the old sprocket in as a sample tomorrow to see if I can get one that will match. I'm a bit miffed right now. I hate it when you buy something, take it home and then it doesn't fit!

Anyway, time for a whiskey...

Tip for the non spanner boys, lock the sprocket using the chain, rear brake etc, not the gearbox, people have screwed gearboxes the other way.

Are you 100% sure about the splines, count the numbers, not that the ends have belled a bit so it is tight? Just a question don,t even know whatbike.

EDIT, Sorry Spyker, was not thinking must be PUI, just typing not thinking, you know your spanner stuff from memory. I did not delete as others may take note.

ALSO, if you find something that wont undo, check the manual,then try backwards, Engineers usd to delight in the odd left hand thread on drives etc. Dont ask how I know.

Yip, I used the rear brake. Worked like a charm.

WHAT you have to lock the rear brake before undoing. The last time I did this on the AT it was way easy. Maby I was just lucky. Or because the bike was in nutral and standing on the side stand.

It just that it is not nice to the gearbox to put it in first and use the box to hold it, fings can break.

Think about it an XT puts out around 35 nm of torque, now imagine putting 123 nm odd through it ! Ouch ! I bet the dealer gave you a cs sprocket for a XT 500.
