[Healeys] Clutch plate

Sun Nov 7 19:38:20 MST 2021

DonIf the brown colored "grit" was inside the dust cap or rubber boot it was from the grease that was packed in there. It transforms from the red hydraulic grease to a dry powder over time.P

Problem found . I was able to remove the clutch slave cylinder. I took the dust cap off and what looks like sand came pouring out . Piston frozen solid .

 re: "the clutch plate would have to be stuck [to the] transmission shaft"

 The most plausible explanation yet. Sitting for years, esp. in a damp climate, the splines could very well 'rust-weld' together given their small clearance. I don't know if it's common practice, but I always put some tenacious grease, usually wheel bearing grease, on those splines (thin coat only).

The clutch plate would have to be stuck to both the pressure plate and the flywheel and or the transmission shaft to prevent movement.    Harold     From: Simon Lachlan via Healeys

 Subject: Re: [Healeys] Clutch plate     After/during a protracted battle with my clutch, I can confirm that it takes a lot of effort to move the fork by hand. A LOT. I used a lever and got virtually nowhere, but then, it seems, I’d been sold the wrong clutch cover. What did impress me was the comparison between how hard/impossible it was to move by hand and how easy it was to get it to move with the pedal once the hydraulics were 100%.  Certainly, I’d want to convince myself that the hydraulics were 100% before assuming that the disk was stuck.

 I think if it was just the clutch disk stuck to flywheel you'd still get at least some movement of the pedal. Early cars used coil springs in the cover plate to hold the disk firm to the flywheel, and later cars used diaphragm 'springs.' I think with either you'd at least be able to move the pedal until the springs reached their limit of travel (or you left leg reached its limit of strength). 

 It's a long shot SWAG, but since the car has sat for a long time it's conceivable the fluid in the line has gelled and/or crystallized to the point it prevents flow to the slave cylinder (I have had BF gell up). I'm not sure you can move the release bearing fork much by hand, though I haven't tried; those are some strong springs in the cover plate.

 Sorry I didn’t finish my story about the fixes I’ve done so far . When I first got the car and I tried to push the clutch pedal it wouldn’t move.  After removing the carbs , which I’m going to rebuild I was able to access the clutch master cylinder. After removing the lines to the master cylinder i was able to push the pedal to the floor . I’m replacing the lines to both the clutch and brake master cylinder. I’m replacing both master cylinders . I’m replacing the hydraulic fluid tank as it leaks. When I got under the car and looked at the clutch slave cylinder, which I’m replacing I can’t move the clutch fork. I can’t budge it , I can’t move the piston rod . I’m going to finish rebuilding, replacing everything in both the clutch and brake hydraulics system. I’m just Puzzled as to why won’t move . Would this happen if the clutch disc was stuck to the flywheel?  I may answer my own question the farther I get into the rebuild. I don’t want to need to replace the clutch.             Don   Sent from my iPhone

  Twelve years could have built up some "goo" in the clutch master cylinder and prevent it from moving the piston. As Perry says, could also be the same issue in the slave. However, the clutch is hydraulic and the pedal does not move any mechanics (other than the piston rod) so it can't be mechanically hung up. The clutch disc is another issue which may show up later, and I would wonder if the brakes are functioning? Moisture really plays havoc with hydraulics especially if the car is not in a conditioned space.       This is a good time to change all the fluid, replace hoses, rebuild or replace cylinders-fun stuff.

 Maybe the slave cylinder is locked up. Pull the pin at the slave and see if the clutch pedal will move.
