Worm Drive

[tonybmw92]

hello everyone

further to my newly installed clutch cable my sv cury got progressively worse in terms of not being able to tighten it at either end without it being really loose still so got it recovered to local garage and turns out its an issue with the "Worm Drive". so my question is . Has anybody had similar problems?. i have to wait until early next week now for them to get the part in stock then it will be around £40 for part plus lord knows how much for the labour!.

cheers

Due to the location of the worm drive it tends to get alot of dirt and if not greased, and this dirt gets in with the ball bearings and the drive movement. Sometimes just stripping it off, cleaning and re'greasing with resolve the problem, but people miss because its behind the front sprocket cover. I myself have replaced them a few times on my own SV's and its a easy job that can be done yourself, as only 2 10mm bolts hold it on plus a tab to bend back. Just remember once its done to take some time and grease it now and again.
If your not sure its all in a Haynes manual, which is cheaper then a garage labour charge, though rubber gloves are a must as its dam dirty behind that sprocket cover.

Still not cheap.. I think I paid 30 quid or something.

I paid somewhere near the £25 mark from spares direct.

As said, it REALLY is easy to fit, REALLY easy. If Grinch can fit one, so can you.

Where are you based Tony as i think i have my old one lurking around in the garage somewhere (It turned out not to be the work drive at all)

Yep, as he said... if I can do it then so can you.

Here's me with the silly question again- was the lock nut tightened properly on the worm drive?

I adjusted it last Weds before a trip to the coast- but like a fool, didn't tighten the lock nut properly. Got about 10 miles down the A3 and the biting point had moved right up to the handle bar. Turns out the lock nut was loose and the clutch arm was slipping, therefore making the cable slack.

Yep locknot was tightened properly, thanks for tip though.

I had the exact same thing, Sid Squid mysteriously diagnosed it over the internet :D With mine, the inner metal sleeve had deformed and loads of ball bearings had fallen out. It's not cheap for the part but it's worth it.

I'm sure you had one or two spares in your SV Goldmine Shed Northy.

Ha! I managed to do that while trying to grease it, turned the lever to get it out and pingfuggit! Spent the next hour or so tracking down all the little sodding balls!
