I have fitted a new clutch to my very old Beta, we think it is a Zero. It has a cable clutch with

a worm gear arangement, there is only one way to fit it so it is sitting right, however when i do this

the spring tennsion on the arm (where the cable connects) is goingin the wrong direction and if i replace

the allen screws and secure the clutch cover the are will not move in either direction.

it's been twenty years since i touched a bike engine but even so, what am i missing here apart from common sence.

any help would be appreciated, the clutch was slipping, so i fitted new plates .

hi

i havent worked on one of these but looking at the schematic its very simular to the yamaha dt model (pre hydraulic clutch)

make sure the clutch pin (shaft in middle of clutch is in correctly it should be behind the outer plate the one with the springs on it) so when its pulled on it would pull the outer plate compressing the springs even more.

make sure that when you join the engine case together that the clutch pull lever (the bit where the cable connects to on the casing is fully rotated clockwise as on these bikes the clutch works by PULLING the clutch plates apart where the new models ( hydraulic works by pushing the plates apart).

on assembling the clutch pull lever on the case should rotate anti clockwise to take up the slack then any further movement anti clockwise should dissingage the clutch by pulling the plates apart.

DONT FORGET THIS IS BY LOOKING AT THE SCHEMATICS .. so hopefully is the right way round (clockwise etc ...)

hope this is correct
