Front Sprocket Tab Washer - SV650.org

squirrel_hunter · 16-07-07, 10:15 PM

Was in the garage tonight adjusting the clutch cable at the engine side when I looked and my sprocket and realized it wasn't quite right. The sprocket nut and tab washer were missing.

I have a feeling it may not have been torqued correctly when I changed the chain (that bit was not done by me) but it had lasted for quite some time regardless. But when I did this I did fold the edges of the tab washer over the best I could. This involved hammering a small screw driver down the back to get it started and then moving to a bigger screw driver to get more angle over a number of sides of the nut.

But is there a better way to bend this washer over or a trick that anybody knows of?

BTW the bike is still on the road, I had a spare washer that I bought ages ago when I did the chain and took the sprocket nut off my spare engine. Properly torqued it up and then hammered the tab washer as described above.

The Haynes manual says to use pipe grips to bend it over the washer stops the nut coming off!! So how did it?

Whenever I've had my C&S changed I've seen the mechanics use a small screwdriver to bend it up. Just make sure it is bent up at a right angle and the edge is sitting against the flat of the nut. HTH

Pipe Grips you say, would I find these at my local B&Q?

And while I think of it, any tips for getting them off again?

The problem with hammering against the nut is that you could end up cracking the tab washer as it is too tight a bend. I too use a pipe wrench and never ever reuse a washer.

Lesson learn't many years ago when the fianl drive of the 1750 Austin Maxi was held on with a big nut and tab washer. Engine out and engine/gearbox split just to replace a 20p washer when ever they failed which they did on a regular basis. Having done it once to repair the manufacturers fault. You would not want to do it again because of your own incompetence

I had this happen on my SV, in fact the front sproket fell off too... found the nut in the belly pan stuck in a oil build up.
