Clutch Slave / Release Mechanism

Date: January 25, 2017Author: littlegreenlandy 13 Comments

The search for a new Genuine Land Rover cross shaft took a while and even longer to ship but finally all the parts needed to rebuild the clutch slave / release mechanism arrived.

The cross shaft, needed a bit of rub down with some wet and dry in order for the new brass olive to fit over. New felt washers were also purchased, the rest of the parts were reused

This hardy little assembly converts horizontal force into rotational force in order to disengage the clutch

Cross shaft, installed, freshly greased and fixed to the clutch slave cylinder bracket with new stainless fixings

New clutch slave cylinder and push rod. The rounded end of the pod pushes into the end of the rubber boot. The threaded end of the rod engages with the cross shaft via a clevis pin.

Pushrod and clevis plin fixed to the cross shaft.

All done. When the clutch pedal is depressed the slave cylinder push rod forces the cross shaft to rotate (through about 20 degrees) which in turn, forces the the clutch release mechanism against the pressure plate of the clutch, thus disengaging the engine from the gearbox. The junction to the clutch release mechanism can be see on the side of the gear box

Excellent work!

Can I ask where you found the red spacer between the slave cylinder and bracket
plus where you sourced the nuts and bolts securing the cross shaft lever and the slave cylinder to the bracket (and the extra nut on the push rod assembly).

Could I also pick your brains on where to find the bolts holding the gearbox brackets to the chassis itself? I’ve sourced most of the parts now, it’s mainly the nuts and bolts I’m looking for.

P.s. does the red spacer under the slave cylinder make any difference to the 9.5″ inch clutch?

Thank you and best regards,

Mark Smith

Hi Mark,

Thanks for the message and the positive feedback. Looking forward to actually driving it again.

The red spacer (originally black) is part number 544686…. and hard to come by…. Quickly measured it and I can tell you it’s 5.2mm thick, incl paint. It was already on the vehicle and presumed original. The Series 2 Parts Catalogue defines the use of the spacer with a 9.5″ diaphragm spring type clutch assembly. (not the 3 arms and coil spring type found on earlier vehicles)

All the fixings are largely UNF stainless and sourced from Wrights Auto Supplies. I ordered one of their nut, bolt and washer packs to start with…. some 400 (or so I recall) separate parts and was sufficient for most things, including the larger mountings for the gearbox brackets.

They also have a decent eBay shop.

Hope this helps and good luck with your build.

Hi again,

Cheers for your help and info.

I’ve since found a slave cylinder bracket and ordered some bolts from Wrights auto supplies and there excellent 🙂
I’ve looked for the slave clutch spacer and found one by chance.
Everything is nearly like new now and sprayed gloss black.

Could I ask what size bolts you used for the angled gearbox foot mounts that mount directly to the chassis cross member?

Just need a few bolts, new wipers, brake lights and hub seals and I’m nearly back on the road!

Fantastic Job you’ve done and I hope you’re back on the road with her soon!

Best,

Mark

HI again!

Found the correct bolts in the 450 Wrights autos supplies set. The original bolts were larger so I got confused over the ones in the set.

Thanks once again,

Mark

  Hi Mark,
  
  Sorry not responding sooner, I’m cycling in Sweden….
  
  I used the largest bolts I could find in the Wrights big bag of bolts…. close to original as possible.
  
  Glad you found something that works.
  
  It’s sounds like you will be on the road soon… great news. I think I will be out and about some time in August / September… with a fair wind. I really miss driving a Series.
  
  Cheers
  
  Andy

  Hi Steve, thanks for the message.
  
  Perhaps the following info will help you. I am assuming you have a 2.25 engine not a 2.6 as the Cross Shaft Assembly is different on the 2.6 (links correct at time of writing 12.01.19)
  
  Slave Cylinder Bracket. Part number: 561242
  https://pablanchard.co.uk/index.php?route=product/search&search=561242
  
  Cross Shaft. Part Number: 537603
  https://www.johncraddockltd.co.uk/search/results.html?s=537603&sb=Search
  
  You might also need the connecting tube from the shaft to the clutch release mechanism…
  
  Connecting Tube. Part Number: 561661

  Hope this helps.

Been doing a spot of research and my findings suggest that the packing piece beneath the clutch slave cylinder is only there if you have a Diesel engine with a 9.5” clutch. I guess that if one has a petrol engine one has the 9” clutch and no packing piece.
And yes, they are hard to find.

  Thats interesting, I hadn’t heard that before. Mine has the factory fitted petrol engine which included the spacer piece… but I have a 9.5 “ clutch… I wonder how LGL ended up with the packing piece.

Thanks for your excellent pics! I was struggling to find a diagram to fix my LR 2a 1970, and this is even better.

Thanks for sharing this helpful information. I’m about to tackle the job of replacing the clutch slave cylinder on my 66 2A. From your photos, you’ve evidently removed at least the floor to facilitate access. Were there any other panels you had removed before doing this work? Thanks.

  Hi Matthew, I had the luxury of having the vehicle in pieces so I didn’t have to fight around the bulkhead or the wing. Maybe removing the wing would be advantageous but I wouldn’t say it was essential. Once you have removed the cradle holding the slave cylinder, its relatively straightforwards.
