I decided to revisit the clutch issue as I sort of broke the master cylinder the other day. I pushed the clutch pedal to the floor which took a fair bit of pressure then suddenly something popped. Why did I do it.... I knew full well it’s not right and didn’t want to be forced but I did it any way. I swear my brains just run straight out of my nostrils some time.
Any way this is the damage damage of stupidity
its blown the top off the master cylinder. Luckily I saw a post on FB that someone was selling one for £10 so I snapped it up and fitted it as soon as it arrived.
After correcting my balls up I popped the gear box off and started to investigate exactly why the clutch didn’t want to go all the way down to the floor.
i measured the old friction plate compared to the new one and there was only about 1.4mm difference so it wast that what was causing it.
Then after staring it it for a bit it I noticed some marks around the spring retaining plate. It looks like the fingers were coming in contact with it.
as you can see the sprung plate protrudes past the friction surface by a fair bit. When comparing it to the old friction plate it’s reasonably obvious it wasn’t going to work.
so after some more head scratching I thought, what’s stopping me from putting the friction plate in backwards.
Normaly you can’t as the sprung plate would contact the bolt heads on the flywheel. However the TTV flywheel is especially deep so after a few measurements it shows there would be at least 12mm clearance between the bolt heads and the face of the sprung plate, plenty of wear clearance.
I also measured the offset of the splined collar. Turns out it will sit 2mm from the end of the input shaft. So with that I can’t see any reason not to install it backwards.
With that I popped the gear box back on bolted it all up and bled the clutch through. I hand tested it by getting the other half to jump on the pedal while I was turning the drive shafts to feel it engage and disengage properly.
So far so good it seems to have sorted it right out.
its funny how some stuff only requires the simplest of solutions
The real test will be dropping the clutch at 4K with a dash of 2 step
a lot of work to be done first though lol
