I was having problems with my new SRM clutch, slipping and dragging, so having read various advice on here I bit the bullet and splashed out 20 quid on ebay for a dial gauge complete with magnetic stand (how do they do it?). So I set it up tweaking the the spring pressures 'till it pulled of perfectly evenly. Wow, what a difference! It's light as a feather, no slip, no drag, changes gear so easily and getting neutral at standstill is a doddle.
Thank you'll and I thoroughly commend this methodology.

(how do they do it?)
It's magic, leave it at that, knowing how it happens used to get people burned at the stake

Good one Ethelred. Now you know it's not all smoke and mirrors.
Best 20 you'll spend this month, and so many other uses for it.
Cheers

*smile*
Also had great results with my clutch (old 6 spring) by painstakingly (no dial) adjusting for even lift.

Hi
Any chance you could advise the E'bay number of this piece of equipment.
Thanks

I spent the last 2 or 3 months trying to set up my 6 spring clutch correctly... *problem*
AFTER reading this post I borrowed a dial gauge ... *contract*
as you said... WOW what a difference...
thanks for posting....
-
sounds like a good idea this thing with with magnetic base and dial gauge,but how do you set it up.could someone post a pic .cheers guys
-
The bottom frame rail is a convenient place for the base. Use the various adjustments on the arms to set the gauge so that it's as near vertical as possible touching the outside edge of the pressure plate such that you can spin the clutch without fouling it.
-
I think you mean horizontal Ethelred.
Mount it to any steel part, barrels, tool box, footpeg. I use cable ties to secure it.
I use a cable tie to hold the clutch lever in against the hand grip and spin the clutch with the kick start lever. Adjust the springs then work the clutch lever a few times and check again.
Cheers
-
Shall we settle on 'at 90 degrees to the pressure plate'
(these Aussie's you know, they see the world upside down... ;) )
-
cheers guys ,got the idea now....something to do this winter i think.
-
well,finally got round to trying this method of adjustment.and yes all works ok,changes ok,no slip or drag,but when releasing the clutch lever nothing happens until the last say 10-20% of lever travel?.every thing seems to work ok but i would prefer a little bit more control,as in when i start to release the lever it starts to bite rather then bites near the end of the lever travel.i am sure i had more before i adjusted it although it did seem to drag slightly.
oh,just to mention its got new plates and springs.
1961 sa A7 with 4 spring clutch
it still rides ok but would like to hear any comments,cheers
-
G'day Rob. You could back the adjustments off a bit. The clutch should be engaging (biting) the last 25% of lever travel. If you have it the way you want it doesn't leave any room for wear of the parts or stretch of the cable. If (when) this happens pulling the lever back to the bar will not fully disengage the clutch and give you drag.
Cheers

Hi Rob,
It will soften up with use, new plates often behave like this
