4x4 ACCUMULATORS SUPPLIED OUT OF DATE (GM) - CHECK THIS OUT NOW!
I have become aware that there are authentic GM Accumulators (GM 90511254) in circulation which have been supplied out of, or close to being out of date - i.e. over six years old. The same also applies to Adams/OPEL on the continent. The one I changed on my own turbo six months ago turns out to be circa 1994.
If you have changed your Accumulator or do not know if it is in date and would like to know, go to the 'Cav16' webpage from here! - and use the email link to email the following information, as taken from your Accumulator bulb.
1. State if the Accumulator Bulb has got a white painted ring?
2. List the two rows of numbers and letters stamped on the casing. (all of them)
You will be emailed back as to whether it is servicable.
The answer to the next question is 'no'.
If the position of the stamped numbers/letters is difficult to get at, then you can release the complete assembly from the bulkhead mounting enough to use a small mirror and torch. (Two 13mm bolts)
### SAFETY WARNING ###
UNDER NO CIRCUMSTANCES ATTEMPT TO RELEASE (UNSCREW) THE ACCUMULATOR BULB WITHOUT FIRST DE-PRESSURISING THE FLUID SYSTEM. THE STORED PRESSURE IS AT 800psi IT WILL KILL YOU, DROWN YOU, OR MAIM YOU. - see the 'Workshop Manual'
CAV16's stock will first service existing Customers, who have already been contacted, and then first come first served. I shall be taking delivery of a set on Wednesday 20th February. The next in two weeks time.
Accumulators supplied by Cav16 come with a personalised label and are priced to include VAT, and UK standard ParcelForce delivery. Next day delivery is an additional £8. The label requires you to supply information about your car.
If you have bought an out of date Accumulator you will need to negotiate for a refund. If it is challenged, get the dealer to ring me on 01 353 749651 and I will confirm if it is out of date.
Be under no illusions, if the Accumulator gives up, it will take out or seriously reduce the life of the pressure plate seal of the Transfer Box.
In addition, be aware it is possible to have a bulb without a white ring that is perfect in every way, just to add confusion to the whole subject.
vauxhall transmission services sell new acc balls and the fact that the ball is 10 years old makes no differance it only starts on the age or miladge count down when fitted so dont panic there are people that will tell you the ball is out of date just to sell you one!
this is direct from VAUXHALL UK and www.v-t-s.freeserve.co.uk sell all 4x4 parts NEW AND SECONDHAND WITH 12 MONTHS /12,000 MILES JUST LIKE VAUXHALL!!!!!
This post was placed on three forums when it became evident that GM were selling a batch of 1994 Accumulators and before it was realised there was a 10 year shelf life. The full story unravelled on CavWeb.
ANDY K - I think this is now a dead issue, but can that thread be located, from the old board, and tagged on the end of this thread for tiggy's benefit please?
However in the pursuit of excellance the stock of 1994 bulbs, I was sold by GM went back for a full refund, on the basis that I would not be associated with top of the range transfer rebuilds and bulbs two years from there sell by date.
Given the fiasco that developed on another thread in this forum can we take it that tigra69 is indeed associated with vts?
- and do you think that, having made a stand on 'slagging off' that the thread I am responding to, is indeed 'slagging off' as you put it.?
VTS? isnt that ULTRAVAUX by a different name? I thought they went bust?
Richard, my Accumulator could do with a change, as it was prolly changed 7 yrs ago, it is the white ringed version though.
I need to get mine changed, but i wouldnt trust vauxhall with it, they said £400, as £65 oer hour....a ripp of or what? you offer a service to fit these as well? if so how much are we talking for the whole job?
Yunis - I am with Andy, it really is not difficult but if you really do not feel you want to do it then print of a copy of the section from the Workshop Manual and get a mechanic recommended and show it to him. The detail describes stripping the assembly off the car and this is not necessary for a change of bulb.
All you need is to:
1. Release the pressure from the system.
2. Use a fabric oil filter removal tool and unscrew the bulb. Be careful part of the regulator piston does not drop out (Tape or wire). A second pair of hands would be useful to steady the assembly during removal.
3. Fit the new bulb with rubber seal provided and screw into place and tighten.
Cav16 will supply a new bulb, and if you wish to test the hydraulic pressure, will hire the kit against a deposit.
Aye Yuniz - Its almost lke changing an oil filter with a ouple of extras which are covered in Richards manual. Any decent mechanic can follow thos instructions and use their own common sense to get thru it.
I will be doing mine in a few years. There weren't any instructions when mine was due
