You can't see my post, TilleyJon? Who's a Mod? A model? Master of Digital? I obviously don't get it. I can see the post so maybe it's a switch I need to flick on my new Joseph account.?

 

It wasn't there last night, I could see you had posted, i tried everything I could think of, but it did't show up.
A MOD is a moderator, they can control/move/delete posts, there may have been a delay because of your new registration.

I will have a ponder over your clutch issue and respond later, I am rushing off to work right now.

Hi Joe,
after pondering your issue, I don't think I have great news, the obvious issues would be contamination of the plate, misalignment of the fork fingers (incorrect adjustment). I assume you have the earlier clutch with multiple springs of course.

A possible, but less likely cause is contaminated fluid in the clutch system, this is the far easier problem, but the least likely, you could replace the fluid and see if that makes a difference.

You will always notice ****** in 1st or reverse much more than an other gear simply due to the fact that you are normally moving from a standstill, and the ****** is amplified by the fact that as the car lurches forward the clutch pedal is also lurching forward from your foot so you would need very precise pedal control to overcome that, whereas when you are changing into 2nd, 3rd etc. the car is already moving so the clutch action always feels less severe.

Remember the days of the learner driver, it was always more difficult to master clutch control from standstill than whilst moving.

I hope that this helps, but it looks like you need to strip the clutch to me, adjustment of these clutches is not straight forward, and ideally you need a proper gauge to set them.

 

Thanks, Jon.
I ordered a pressure bleeder, to eliminate that problem and be sure the fluid is good and air free. I will double check the slave pedal adjustment. If that doesn't do it, I'll push it out of the garage, point it in a clear direction and try to drive it or else have it towed to the local vintage Jag repair shop on my side of town. Again, thanks for the advice.

 

No problem Joe, hopefully it is an easy fix, and not the actual clutch.
If it is the clutch, you may be able to change to the newer diaphragm clutch, I think some of the flywheels will take either, but I would have to check that out, it may be that the flywheel need drilling to take the newer clutch, but they are so much easier to install as they don't need setting up as opposed to the spring type.

 

Just thinking about it the ****** could be caused by the damper springs in the drive plate failing? Never come across it myself but there’s a first time for everything.

 

It absolutely could be Rob, not quite so likely the cause on this type of clutch due to the orientation of the springs, but still a possibility. Hopefully Joe can find an external problem which doesn't involve the engine out !

 

I pushed out of the garage to avoid leaping backwards, pointed to the street and drove it about a mile using 2nd-3rd and 4th with with no problem, slow coasting through Stops in 2nd dragging. But given the morning traffic, I decided not to chance it further and called AAA. They towed it to Consolidated Auto Works, a most experienced Jaguar shop, and in a few minutes they diagnosed it as needing a new clutch master cylinder.
This was quite a relief.

 

That's good news, glad it's a simple fix, the car should be as good as new shortly.

 

Joseph if it is at Consolidated you could not do better! Tell Barb and Ed hello from me! Ask Barbara about her tattoos!

 

Consolidated replaced the master cylinder with a new one. Apparently the interlock/detent may need attention too. But in the meantime, we just won't push the stick so far forward. That prevents it from getting stuck in 1st.Through freeway gridlock, through downtown, I delivered the car today to my youngest son ,James, who now has a garage for it, together with all the parts and items, manuals, a floor jack and stands. I've put 150 miles on the car since getting it drivable. Now I'm going to refresh my garage and prepare it for the return of my '40 Packard Super8 Convertible Sedan, which is being meticulously restored by my eldest son, John.

 

Fantastic Joe, James is a lucky chap, sounds like you have quite a bit of talent in the family.

 

Joe until you take the box out and fix the detent yo can pull the top cover and place a spacer on the operating rod to prevent shifting too far.

 

Thanks, George. I repaired the detent/interlock on the Packard by removing the center plate in the floorboard and then the lid of the transmission. The detent is part of the lid on a Packard, so it's easy to fix it on the bench. I'll check the book to see how the Jag is set up, but that sounds like a great interim fix. Once I knew not to push it far forward, it didn't get stuck again. James was able to drive it around his neighborhood last Saturday when I delivered it without getting stuck. Here is the set up in the Packard and the condition of the ball bearings and springs when I opened it.
