Re: Accumulator cut out valve

Very much the reason why accumulators should be overhauled by a company that DOES check the cut out valve or the non return valve. The cut out valve in particular controls the entire system. A bit like having a brand new tyre and not renewing the inner tube.

Re: Accumulator cut out valve

I've heard varying tales about who-overhauls what. I've not had dealings with Hebble so can't comment on them. I have had dealings with Imperial for a number of years now and have seen their workshops and watched various bits of kit being overhauled and tested.

I admit I have had problems with 2 or 3 accumulators over the years from them, and each time they've been replaced or re-done without question, even when one was well over the usual warranty date they give.

One was earlier this yer, a unit leaked air as it was fitted, replaced without question; one a couple of years ago leaked as Brian describes from the cut-out valve, that was changed without question, the other was so long ago I can't remember!

It really isn't worth just repairing half the unit, on a safety critical item like an accumulator or a foot valve, don't mess with them. I've tried overhauling one myself without much success. a lot of my work is abroad and the last thing I want is units failing abroad a short while after fitting them. There is no cheap option.

It's much like people who want gearbox parts. I won't supply any as I know that unless they know what they're doing the box will fail again soon after. Change the box for a factory recon unit. I know they're getting bloody expensive, the last couple I've had done were in excess of £1900, but they're done by a reputable firm, bench tested and should last along time..
