Okay another update. We've hit a further snag - sigh! - and we need someone's help and advice, again. Per Chris' email and annotated pictures below. Hopefully this is the last snag...
"The [rear hydraulically adjustable suspension's hydraulic] reservoir is constructed with a reservoir chamber surrounding a central tube that acts as a cylinder when the plunger is pushed in. This cylinder has 2 feed holes about an inch from the bottom and a bleed hole nearer the top. The outer chamber appears to be soldered to the cylinder top and bottom. The plunger has a small rubber seal on the end, made so that it locates into the end of the plunger and seals much like a clutch slave. The reservoir has a sprung ball bearing type valve that is in good working order.
The rubber seal has signs of wear and cracks, I don’t think it will work as it is, fabricating a new piece of rubber is going to need some thought.
There is still something loose in the reservoir chamber, it can’t be seen, I have a feeling it is a lump of coagulated anti-freeze. I don’t think it will do any harm leaving it in there. If you do want to have it stripped and rebuilt we are going to need to find a specialist, I don’t know anyone who could do this, I think Joe [Chris' go-to man for fixing things like this; see previous post] has done a good job of sealing up the chamber but I am sure he won’t want to take on the overhaul."
It's been such a mission this car and, well, I'm running out of steam even if Chris isn't! So, any thoughts or advice, or does anyone know of a specialist who could take this on, either the rubbers or indeed an overhaul? because the rear suspension won't work (properly) without it and I want it right in deference to Paul Atkinson as much as anything else. I know how important the car is re the Augusta section of the LMC.
Thanks ever so much and all best cheers,
Mark
