Thread: Easier to Bleed Clutch Slave Cylinder

Hello All,

Gee did I have some fun tracking down a supplier for the two copper washers! I went to three places today. Jacobsen Engineering, a truck place and then a specialist diesel injector place. Third time lucky. The brass elbow is a banjo fitting and the bolt is a banjo bolt.

No one knew the origins of the banjo fitting elbow. I guess that it is off a tractor. I will track down a supplier of the banjo fittings and post it up.

My wife Leeann had to act as a chauffeur as I still cannot see properly. Wasn't Leeann happy driving around town for the three copper washers, worth the massive amount of ... $2.75. We chewed through lots more than that in fuel

Kind Regards

The hollow bolt & banjo fitting are used in pneumatics but I haven't seen the version you have where the outlet is at roughly 45degrees.

If I remember I'll ask a couple of contacts in the industry.

Hello Colin,

Thanks for the reply and the idea asking your contacts.

The bloke at the diesel injector specialist suggested the part could be banjo fitting from the hydraulics industry.

I was going to see the local folks at Enzed - maybe in a couple of days time when the chauffeur won't bite too much

I'd have to check what pressure can be generated in a brake system but pneumatic ones should be OK. Problem is most will be a BSP thread which will not match the bleed nipple on the slave cylinder.
Originally it would be UNF but not sure with pattern parts. The hex size of a pattern nipple is metric but probably with a UNF thread.

Best of luck at Enzed.

Hello All,

I have been working on Batty today and swapped over the brake pedal box and clutch pedal box. These were complete with new respective master cylinders. In preparation for tomorrow's work I scoped out the clutch slave cylinder and knock me down with a feather - what do I see?

Gee - that banjo fitting on the clutch slave cylinder sure looks familiar! Batty is an ex-Army Fitted for Radio so I went under my other FFR and knock me down with a feather it had one too

The interesting thing is I found the first modified bleed screw originally on a civilian Series 3 with a stock standard 2.25 litre diesel - so a four cylinder.

It may not be a coincidence that two FFRs have the same fitting.

Colin and other Series 3 FFR owners - do you want to check to see if the bleed screw adaptation was an Army thing or a specialist FFR modification?

I also noticed that the slave cylinder is swapped around on both Army modifications as they have the bleed screw on the bottom and the clutch line on the top.

Colin my pressure brake bleeder recommends not pumping up above 15 psi. So maybe there is not much more pressure within both hydraulic systems; above say, 30 psi. It would make sense to recommend a figure that allowed some safety margin before any seals get blown out.

Kind Regards
Lionel

My Series 3 has the same fitting, I thought it was standard on the Series 3 and first appeared on our old diesel series2a

G'day Peter,

Well the information about the adaptor coming on a Series 2A diesel is interesting. I have a number of Parts Catalogues and they are not shown or mentioned.

I browsed through my Australian Army Repair Parts Scale 6 cylinder petrol Engine Manual Transmission Land Rover Series 3 November 1988 Issue 1 and the part is described as:

Bolt fluid Pressure UNF Steel CAD plate D, 3/8 In. by 1-1/4 LG

Washer flat Banjo Bolt

Connector multiple fluid pressure brass angled , W/3/8 In., UNF Female Thread and 7/16 in. I.D. Eye 1-5/8 in. OA LG

Washer flat round copper 3/8 In. ID 19/32 IN. OD 0.048 in THK

The details are on Page 97

Kind Regards

Hello Peter and other interested readers,

Peter was absolutely correct.

After finding the part in my Army Parts Scales I grabbed a copy of my Green Book the Land Rover Series 3 Repair Operation Manual (1981); I found the parts pictured in there. I then looked up my more recent Brooklands (1988) Parts Catalogue; parts pictured in there. I then went back to my genuine Land Rover 1975 parts manual and found the parts listed in there too .

The Parts are listed as:
Banjo Bolt 512235
Washer 216914
Banjo Slave Cylinder Bleed 90622182
Washer 233220
Bleed Screw 556508

So what must have happened is when people like myself buy an aftermarket slave cylinder they only come with a bleed screw. They must no longer come with a banjo fittings and people just use what came in the box. Earlier a previous owner must have thrown out the old slave cylinder which had the banjo fittings still attached. This then becomes the normal practise as other clutch slave cylinders are purchased. Then one day muggins-me comes along and I think that I have found a brilliant adaptation that a previous owner did.

My apologies for steering people down the wrong path. Gee no wonder it was previously hard to bleed my brand new clutch slave cylinder - it was missing some old parts! Parts that the clutch slave cylinder was designed to have in the first place. Doh!

Postscript:

I checked on John Craddock's site and also LR Series and they both sell the banjo fitting 90622182 - Banjo Slave Cylinder Bleed Series 3
