Sherpa 199B Clutch Push Rod

Featured Replies

In the midst of my Covid199B restoration. 
Can anyone confirm the actual length of the 199B Clutch Push Rod.

As ever thanks for the assistance.

I'm rebuilding 3 199B engines at the moment. One looks as though it has never been apart before, the pushrod in that is 185mm.  The rods in the other two are 187mm....

Glutten for punishment.............

I think I’ve given myself a clutch problem - I’ve had the timing side cover off whist I’ve been doing some rewiring, put it back on this morning but now the clutch doesn’t feel right - lever is very sluggish to return and feels much too light.

I stripped, cleaned and regreased the actuator arm but suspect I may have lost something - the pushrod extends 16mm from the sprocket not including the felt washer, but there is 20mm from the edge of the casing to the actuating arm, what have I lost / done wrong? I’ve had a google but can’t find a very detailed drawing of the actuator.

Ball bearing definitely there, is there anything that could have fallen out when I had the bike laid on its side?

didn’t see one when I took it apart. I’m going to adjust the cable (I didn’t clock the how it was adjusted when I stripped it) and see what that does

Check first, but sure there should be a ball bearing in there.

Sorry, to be clear do you mean the ball bearing in the actuator shaft or is there one the other end too? If so that may be the problem, the actuator rod fell out when I had the bike on its side and I may have lost it :(

There is a ball bearing in between the pushrod and the mushroom shaft on the clutch end. It is around the same size as the pushrod. Any pushbike shop should have one but you may have to buy a few to make it worth their while. Graham.

You have put the thrust bearing in, sits on the back of the pressure plate, between plate and mushroom.it can fall off whilst disassembled.
