Clutch Bleeding Help

[PeterAllen]

Have an 87 RR and changed the slave cylinder recently. Now am having a hell of a time getting any clutch pressure. Master seems to be working and even reverse bled the slave still no pressure.
Anyone know a trick to get this done??https://www.aulro.com/afvb/images/imported/2013/08/1312.jpg

Hi there,

I had to do the county once, not too difficult if you have a second pair of hands, as its usually a two man operation.. I found out the hard way.:angel:

I had to prime the lines by getting the Mrs to pump the clutch and fill the reservoir whilst i was beneath opening the bleed valve. If you have any leaksin the hard line you may have to rectify the problem before you proceed the bleeding process.

I gained clutch pressure after repeating the process mentioned above. From memory the Isuzu bell housing made it a little easier than the V8... Or was it the other way round?:blush:

Hope this was of some help.

Thanks, Have tried all that and some. Have you any idea how far the rod that fits into the slave cylinder should extend out of the engine when the slave cylinder is removed. Feel that the slave cylinder doesn't push it in far enough to engage. Then again that shouldn't stop it from being bled. I may tryto make up some pressure bleed gismo and see if I can pressure bleed from the master cylinder.
If its not one thing its another.

Peter,
I experienced similar problems with my 1984 manual RRC. The problem with manual bleeding etc is the long horizontal pipe section across the firewall. any air collects here and rises up the pipe down to the slave, between pumps etc.
I used an old 1l thinners can, added a wheel valve to the centre of the cap (but leave the valve out) and put a airline fitting through the bottom. Ran a clear tube from this fitting to the slave bleeder. filled can with fresh fluid, and tilted it to ensure max coverage of airline fitting, used my air compressor to pressurise the can (only enough pressure to get the fluid to move smoothly along the tube, the can may bloat a bit). open the bleed on slave, fluid builds up in master cylinder, and eventually overflows. Remember to stop if you see air in the clear line from the can!.
