Now in 2000 me and my faithful mechanic/ team manager/ car husband - well we had a nasty vibration moment in Vimoutier in France. We were en route to Laval to do a 1000 miles in 24 hours when the clutch bearing went ....
We got towed back 200 yards to a Monsieur Rideaux's garage on a trailer behind a WII Willeys jeep where we found hundreds of Hitler's bearings. We had teamed up with the ex captain RR who went on a mercy mission in his Anzani and we were eventually back on the road in several hours... It was a stressful day working a few feat next to a stream with an unexploded bomb ... but we managed not to swap the Nash for the Monsieur’s Schwimwagon... it was very close.
Anyway this is how it shouldn’t have been assembled- so BH (before Huddersfield)
and after Hu
ddersfield ....
TIP TOP.....
spot the difference the 1st collar has been reversed.....
so when JB put the clutch back in JB noticed there was a bit of an angle of the drive springs!
(3 lines, beautifully curved in the picture) The ones connecting the flywheel to clutch, like steel rulers should be ideally flat. It has obviously been like that for years!
Note the clutch toggles are barely caught by the big washer which depresses them? So two flew out when JB tested them. So he made an extra big washer to correct the problem. It’s a spigot fit to retain balance onto older smaller washer. It’s held in place with tension of main spring so they now won't fly out.
He also added an extra sleeve to fit round prop, which helps hold main clutch spring, supports it in the bore , as there is always too much clearance. Helps keep the assembly in balance.
The nut which holds the clutch driven plate has a diameter sticking out the end which locates in the flywheel. It wasn't concentric with the prop shaft so the pedal was vibrating badly. HM machined it concentric, and sleeved it (only 1mm thick sleeve) so it all runs more true. But…the thread carrying the nut was also not true. So now this nut must always be tightened to the same orientation in future. Fine for normal strip down and re-assembly, but if the taper is lapped, then a washer must be added so that the nut retains its orientation when tight. Or this work will be undone, and it will be like before.
