Chain and sprockets change HELP!

**offrd** · 4th April 2009, 17:14

Ok, well over due time for chain and sprockerts on the dakar. Parts are in the shed and bike is pretty much in bits but, i did not realise that i needed a 30mm socket and power bar to get the front sprocket off!

Having moved to Auckland recently and not knowing anyone really up here that i can go and borrow bits from unlike back in Tokoroa...

I really need someone with a few tools a a bit of time to give me a hand.....

Anyone???

Oh and a dab of locktite would be pretty helpfull too!

Thanks

Ah well, all sorted...

I've had the same problem. Took mine in for a warrent. Soon after, I wanted to change the front sprocket. Not a shit show of getting it off. Took it back to the shop. They looked a bit embarased when I saw them swinging off a 3 foot long piece of pipe with a socket attached.

I've had several bikes that needs more than a rattle gun to dislodge the countershaft sprocket bolt. The ol' long pipe and a socket trick nevers fails to work 'em loose. Extra leverage is what does the job.
Try undoing some of them clutch holding nuts and then the fun really starts.

What would you rather have? Sprocket falling off on the road? Believe me that has happened......

Once you have put a dab of loctite on the threads, then torque it up (& its had time to set) it can take some shifting

**warewolf** · 4th April 2009, 21:26

Aren't you supposed to use heat on loctite to break it loose anyway?

Tip on changing countershaft sprockets - put your bike in a high gear with the chain still on...

and have a mate STAND on the back brake while you swing off a fooking long piece of pipe with all your weight

Well the pipe and socket idea might be a good one, but when you just have a repco cresent and the tools the bike came with... That aint ever going to happen!

But using what i had i still got it off not a problem, just had to think of the solution.....

One person too....

Surely low gear (1st) offers maximum resistance ?

Nope, think about it in terms of engine RPM's.

What's the reason why bike manufacturers have moved to this method of retaining the sprocket? Simplicity? Price? More reliable?

Two 10mm bolts holding an interference plate in place in front of the sprocket seem to do just fine and are a piece of piss to get on and off. Is this design confined to previous generations now?

That IS a very good question. Those big nuts are a pain.
