Undo the locking screw on the outside, remove the fork piece on the inside and the complete mechanism comes out from the inside

Brilliant thanks ... I'll do it when I change the oil and replace the push rod .... and hopefully the 3 x casings that will have been polished by then !!

Hopefully if a bit is protruding you can grip it and draw it out. Mine was broken behind the plate with the hole in, the shorter piece had been put in back to front so the shaped end had peened the tip of the long section so it was too fat to come out through the hole.   >:(

So ... all set today to swap the push rod / change the casings and refresh the oil / filter etc

Question ... if i have to get the pushrod out from the clutch basket side - is there a torque setting for the nuts when re assembling - I've looked but can't find one ?

Thanks

Simon

Manual calls for 7.2-10.1 lbs-ft which seems way high. Never used t wrench, I just tighten em.

Modern manuals say 6.5ftlbs for a 6mm screw and 7ftlbs for a flanged 6mm bolt.

I marked mine with a sharpie and tightened them to the same point apart from one that was probably a bit under in the first place. There are stories of over tightening, including due to torque wrench not working properly, and the basket cracking. They don’t need to be very tight, I got an impression when undoing them, maybe mark and then use a very low torque to ‘test’ the mark.

Standard torque settings really depends on thread type and bolt type. The higher values correspond with high tensile and fine threads. Go by the  manual, assuming you have the correct fixings.

I always used my thumb as a guide, I'd put my thumb on the side of the head of the ratchet and when it felt tight enough I'd stop. I checked it once to see how much I was putting on there and it was perfect so I always do that now.

1974 manual calls for 6mm hex bolts 5.8-8.7 lbs ft
Clutch spring bolts are especially picked out as higher, up to 10.1.
Maybe one of the many mistakes and maybe they had a lot snapped.

That would be for for a ‘fine thread’, which they are….
