clutch not engaging?

[Nium]

The rover i took the trans out of had the same pressure plate and spring on it (out of a series IIA)i some how added the spacer to the slave so i will remove that. the new pressure plate is identical to the old one other then not having that spacer in are you positive that i do not need it? sorry for questioning but i really want to get this right.

Mat, don't worry about questioning it's the only way to find out what you want to know. Personally I always to try and ask as many questions as I can think of.

In terms of the spring attached to the slave cylinder reference in the Green Bible Part 1, Operation B1-9, Page 20-B top left of page under
"The following information concerns early and late type clutches.

Late models have a hydrostatic clutch, that is, clutch mechanism which requires no adjustment for the life of the clutch plate.

(c) Return spring is not fitted to the operating lever on late models."

In regards to the pressure plate.
The pressure plate (your picture DSC05876-1.jpg) that was originally fit to the truck is a 9" coil spring type pressure plate usually they are replaced with the larger 9.5" pressure plate and clutch disk.

The other old pressure plate (image DSC05875-1-1.jpg) is the later type 9.5" pressure plate normally fitted with 9.5" clutch disk.

The one you have installed should be a 9.5" pressure plate and clutch disk. After looking at various parts suppliers the pressure plate (DSC05875-1-1.jpg) is still available but it is not necessary. The one you have fitted is the same one that I fit to my rig when my original coil spring pressure plate died. The center piece isn't necessary many, many vehicles use pressure plates exactly like the one you have, in the tranny right now. Don't worry about that center piece it's not necessary even if you can buy a new pressure plate with it fitted you don't need to. Also the center piece is a part that is installed by the manufactorer so it wouldn't be a good idea to try and take it off and fit it to your pressure plate you wouldn't want it to fall off inside the bell housing, bad things would happen if it did. Borg and Beck were the original suppliers of the pressure plate. Green Bible Part 1, General Data Page 26-B, Section "Clutch, diaphgram spring type". I believe Borg and Beck is now renamed AP Borg and Beck. The pressure plate should work fine once you get the spacer removed from between the slave cylinder and the slave cylinder support bracket.

Once you have the slave cylinder back in the bracket follow the procedure in the Green Bible Part 1, Operation B1-9, Page 21-B "Hydrostatic clutch mechanism-Late Models" to properly adjust the slave cylinder. Use method "a" or "b" in step 2, whichever you find easier.

Never hesitate to post questions if you have any. Hope that helps.

Thanks for the pic of your Landy looks real good you done a helluva great job!

Hello there,

Looking at the pix. it appears you have a Series III pressure plate fitted, not the 9.5" IIa style with the triangular spacer for the clutch realease.
Please confirm the style of clutch cover fitted.

Les,

If it is a Series III clutch cover are there any issues with using it with a Series IIA slave cylinder set-up. I ask because, from what I remember, I had gotten a Series III 9.5" pressure plate (clutch cover) and clutch dick from you guys years ago and have been running them in my Series IIA, with the hydrostatic slave cylinder set-up, without a second thought.

Not to mention I'd hate to have been giving Mat bad advice.

lease confirm the style of clutch cover fitted.

Thanks Les!

i contacted Aurther at Rovers north and ordered the 9.5 IIA Pressure plate.

just wondering.. would it be an option to pull the triangular spacer off the old clutch plate and put it in the 9.5 pressure plate?

Thanks again!

I believe the 9.5" plate comes with the triangular spacer.

[Les Parker]

The spacer is pressed onto the diaphragm and the diameter within the fingers are different, so I do not think this would be viable.

[Les Parker]

If this is a late IIa with 9.5" clutch plate/cover, there should be a triangular flange in the centre of the diaphragm, form the pix I cannot see this.
