thrust rod !

Post  Greecegun on Sun Jan 10, 2016 5:11 pm

hi all, have just replaced the cork on the clutch plates, and put it all back together, but bemused to why the clutch would not engage IE nothing on the leaver. so took back to pieces and it looks as if the thrust rod end is not making any contact in the bell housing on the clutch plate - so do i need to add more rod, or get a replacement thrust rod end .. as it was all working and engaging previously before i dismantled. but corks where all worn, so thought would it was slipping when i tried to kick start the bike. i have altered the adjusted screw on the opposite side and turned that right in, but nothing, so guess i'm a few MM short on the rod
its a 1948 villiers 199cc or have i missed something ?

thank you

You could try adding a small ball bearing .Cut the push rod in two and add it in the middle , or get a longer rod . I think there has been a thread on this.

As above

Agree with the above post, saw the pushrod in half and put a ball bearing between the two halves, it is also worth heating up the cut ends of the rod to red hot and dipping them in oil to cool them, this will harden them and prevent the ball bearing indenting into the ends. Best to cool In oil rather than water as this will reduce the brittleness caused by sudden cooling effect that water will give.

Its just a thought but are you supposed to flat the corks off to a given thickness?
