Sometimes we forget the simple things

Postby Storkfoot » Tue Feb 12, 2019 11:53 am

Properly functioning Surflex 5 plate clutch on TS1 but changed gear housing and lever as old pivot hole was way over 8mm

Clutch then starts dragging badly. I then wasted a couple of hours before I remembered that sometimes just taking a dremel to the lever works


Just thought I’d share this as it has helped me sort clutches out in the past.

Good point. Can also be the result of fitting balloon grips or poorly shaped levers, including some of the dog-leg levers on the market, which hit the grip very quickly.

There are two other ways of obtaining more movement in the depression of the clutch that many people overlook:

If the crankcase cover lever is lifted from it's splines & rotated ACW (toward the rear) to a more acute angle, then more angular rotation is obtained. This may contradict what manuals may advise for the lever positioning, but it works. (Think of a piston near TDC & how many degrees are rotated for very little linear movement & you might get why it works)

Similarly, if the crankcase cover lever is cut & welded shorter, more angular movement will be obtained. This was an absolute must when nine plate clutches were utilised.
