Morning Gents, Please could I ask for some assistance?

Q:

1. Is there a spacer between the engine block (n/s and o/s) on the Accumulator body?; mine appears to be missing. Is it supposed to have the mounting bolt thread exposed when viewed from beneath?

2. In the reservoir there is a plastic float beneath which is a rubber "donut". Which way up is this mounted.?

3. Does anyone know of an alternative source for the aforementioned rubber "Donut"? they are priced at nearly 50.00 each which seems to be extortionate.

Thnx for your help.

Stay safe.

Best.

Mike

No aftermarket replacement for the donut (seal). Note: The float goes in one way . Are the screens split? If so they MUST be replaced.

Point 1. The accumulator can be quite difficult to relocate after removal ..re weight of same and locating the bolts... seat/location.
To answer you question, you won't see thread if bolt was seated correctly .. Infact from memory the bolts may well be of differing sizes depending one location, (this may well be the reason for same)
Again from memory... one my only have, approx 10 cm from bolt to engine block.. to work with.

Point. 2 the rubber "donut" slim portion touches base, with the wider side facing uppermost.
If it's not disintegrating or (has not already disintegrated) , clean and replace, it just acts as a cushion that offers correct seating to the plastic float.

Michael, flying spares may have good second hand donut shaped rubber units for sale, at a more realistic price...

Gents,

Thank you for prompt response. I've spent the past few weeks renewing every brake pipe and flexi I can.

Along the way I've remedied a few lazy technicians work (rounded shoulders on nuts, missing clamps , broken bobbins etc) It's been a useful and heartening exercise.

I've had the luxury of a two post lift and four, super strong, five feet axle stands, but my poor back is now hurting from bending into unusual postures whilst cursing lol!
The good news is that the car has never been welded at all, albeit it now needs a lower wing repair and rear wheel arch, but frankly it's a nothing; I'm really pleased.

The high pressure pipe on the o/s snapped at the gland, despite a week of Plus Gas application, before attempting to unscrew it.

I'm thinking of putting a small section of Aeroquip, perhaps 6", to provide some flexibility in the pipe and facilitate replacement.

Re. The Donut, I still have the old one but somehow, it's been torn, which I find hard to understand.

I don't mind paying a premium to the specialist suppliers, after all without their business success we may be left in the "Stum" for obsolete parts but even that logic gets stretched at 50 a pop; I'm thinking along these lines

Thnx again for your help.

Michael, that grommet in your link is made from Buna S rubber which is not compatible with glycol based brake fluid which is what RR363 is composed of. It will swell and deteriorate fairly quickly and the bits could clog up the filters in the reservoir. Whatever you use, it must be an EPDM rubber compound like the original.

Each accumulator valve body has a spacer (distance piece) part no. SPC1757 on the A-Bank and SPC1758 on the B-Bank. These distance pieces fit between the part of the accumulator valve body that sticks out like an arm at one end and the engine block. There should be no thread showing between the accumulators and the block. I think there could possibly be a risk of that portion of the accumulator valve body cracking off if tightened without a distance piece in place on the threaded bolt.

PTFE Teflon would work just fine, as would nylon, polyethylene, even ABS plastic. All those plastics are compatible with glycol brake fluids.
