#26 Re: Maintenance » Rear Load Proportioning Valve stuck... or is it??? » 2019-11-21 02:45:18

Because of inertia, a lot of the weight of a vehicle will transfer to the front wheels under heavy braking. This means that the rear of the vehicle will tend to rise and eventually skid.  The idea of of the valve is to cut brake pressure as the suspension rises , to stop skiding, the more heavily laden the van is the less the rear rises and so more of the pressure is allowed through to the rear brakes.

I very rarely carry heavy loads, so I suppose that the valve hasn't had a lot of use. Bearing in mind that I have owned my van for over 12 years and never paid the LPV any attention - will it still be OK? Or am I worrying about nothing and if it passes the MOT every year it must be OK?

When mine failed its mot I was told that the difference in load proportioning was 80% / 20% when I think the max allowable difference was 20%.
Don't quote me on the numbers but it was obviously quite bad. They suggested even dangerous and that I would suffer from uneven braking in an emergancy stop. However in use over 25,000 miles I never had a problem. Loaded or light.

On three different occasions I had it inspected and lubed with no detectable faults, but it still failed mot 2 years running. (there are of course, other mot testing stations available. wink) When I finally had it replaced it it resembled an undefined lump of rusty slag.

I don't understand it's operation but think it optimises braking force between front or rear axels depending on rear loading.  (A bit like when I used to put a bag of cement in the back of my Reliant Regal Van when empty. smile)  I don't think the mechanics who checked it understood it properly either.

So for me, yes, a knackered one was ok so long as I could get an mot. 

Mind you, it is possible that anyone brought up on anti lock might have more of a problem.  Anyone familier with the braking on almost any vehicle pre 80's should be ok.  We only had manual load ballanceing via the handbrake then.  smile

The pressure in a hydraulic system should be the same everywhere ( like current in  a circuit) so either one of the little valves in the load valve was stuck down ( not very common) ... or some fluid was leaking out of the wheel cylinder on one side wetting the shoe and reducing efficiency  or  wheel cylinder siezed. Both last two common problems  with rear drum brakes.

Just to chuck in my three hapence worth....... The logic used in chips works on 5 volts . However  the readings are taken from the middle section around 1-4 volts . So anything more than 4 volts or less than 1v , is considered ' not a coherent reading'  That way if a reading is 5 volts for example , you can be fairly sure that something is shorted to live , likewise if a reading is 0 volts you can be fairly sure that it is short to earth.

Most systems do a 'post' which is "Power on self test" an ABS system is a perfect example, it checks all the circuitry and wheel sensors  so if a light comes on and you aren't moving  you can be fairly sure that its a bad connection in a wheel sensor. 

Yours is a similar fault in that it has 'failed to communicate' , its not shorted or anything but under test the sensor/circuit isn't  testing within the limits.

As well as the wiring it could be a faulty plug, they are designed for a limited number of plug ins/ disconnections and a certain lifespan ( say 0.01% faiures in 100,000 hours type of thing) so never assume it's not the plug . You are looking at the bloke here who bought 2 x wheels sensors and the fault was eventually  cured by soldering in 6 inches of wire and a sensor plug off a scrap car.....  Best of luck.

The DVLA have got them selves into a bind here. It states:
In order for a converted vehicle to qualify as a motor caravan it must have certain minimum features, as follows: A door, A bed, A water storage tank, A seating  arrangement, and  table, A permanently fixed means of storage, A permanently fixed cooking facility, At least one window, present, permanently fixed and installed properly.

If the vehicle has all of these features present, permanently fixed and installed properly, then it is a legal requirement to have it reclassified as a motor caravan  Yet when you apply , the application is turned down on the appearance qualification mentioned in paragraph one. So it's a legal obligation, and yet when you apply it is declined. Sounds like a catch 22 situation to me guys.

Do or don't you are in the wrong. Pressure needs to be put on the DVLA to decide which case they want, the law needs to be tested. 

Somehow.

Starter is on the front just to the right of the diesel pump, fastened on with 3 bolts/ allen screws. Have a jack ready, it's impossible to remove the top  covers until the engine mount is removed

#31 Re: Maintenance » Lights on warning buzzer - does this van have one? » 2019-11-01 11:43:05

Hi there , finally dug one out , sadly it won't go through the post offices letterbox, so postage will be £2.84 ( I think , will check) If you want to call it a fiver, in total.
3 connections , ign on , lights on and a connection to earth , via the door switch for the interior lights . When  ign off and lights on and earth connection ( door open) made buzzer sounds. All other cases silent.  From memory the relay plugs in somewhere beneath the dash column area .  Could be wired up relativelty easily  from scratch .

There is a sensor reads off the fly wheel.  Black sensor in clutch housing leading to quite a chunky brown plug somewhere around the fuel filter area.

A very powerful diagnostic tool is the question > " What happened last?"  In your case as the answer is  'I had a new clutch fitted ' There is a 90% chance that somehow the cable that does the forwards and backwards  (1-2 3-4 etc) hasn't gone back on quite right for some reason.

#36 Re: General Discussion » 03 Dispatch 1.9D Starting Issues » 2019-10-04 19:07:08

Especially with the change in the weather the heater plugs are most definitely the main suspect here. The black smoke tells you that there is plenty of fuel , it just won't start burning!
A simple way to check them is to disconnect the wire that links the 4 heaters from each individual  heater plug . Then hold a wire on the battery + , then brush the wire against the terminals of the heater plugs, if they work there will be sparking ( each plug pulls about 6A), if there is no sparking then it's a duff plug.  Be careful with the wire , its live and unfused so if it touches anything , it will short or spark like mad. Don't turn on the ignition.......

It's always good to know the outcome.  Glad it's sorted.

#38 Re: Maintenance » 2008 Dispatch (jumpy) pneumatic suspension looking for diy fix » 2019-09-07 19:08:31

If yours has burst a bag , I wouldn't worry too much about de pressurising the system. If there is some residual pressure in the ' good' bag jacking it up will tend to reduce the pressure as you take the weight off the axle. Leave it overnight and the pressure may well leak away.   I seem to recall that there is a little height valve/ electric switch somewhere linked to the rear axle that controls the pump.  If it was going down over night previously , presumably it just pumped itself up when you turned on the ignition/ started the engine, so starting from flat it should just pump up and it will turn off at the appropriate height.  If the vehicle is on stands it may not pump at all as it will think it is too high and needs to let pressure out! Try lowering it down and then trying .  I'm trying to remember , I've done these on Disco's and also a Freightrover riot van,      ( like 20 years ago)  I don't recall there being any big problems  repressurising .

#39 Re: Maintenance » 2008 Dispatch (jumpy) pneumatic suspension looking for diy fix » 2019-09-07 12:18:53

Unlike Citroen Hydraulics, I can't say I'm very familiar with air suspension, but certainly on Discoverys the first sign of a problem was that the bags used to leak so the pump ran all the time, the way to check this was to spray the bag with WD40, if there were loads of bubbles then it was time to renew the bag *** before it ruptured***.  It sounds like one of your bags has gone beyond this stage and actually ruptured.

The ebay advert says the bags  fit various versions of the Jumpy and I suspect that the item would fit yours too. Why not contact the seller and check if you are not confident. Most car parts are made by third party suppliers, not the manufacturer themselves , like Valeo alternators and Bosch brakes, these air bags will be bought in by Citroen.

On Discos the pressure pipes were a simple push fit system with 3.5mm pipes and a ring that was retracted to release the pipe ( when pressured down obviously). The disco units were held in place with a couple of bolts in an end plate and a cup the other end fitted into.  These ones look like they just fit into cups , but until you examine them it's hard to tell exactly.  You can't drive your vehicle with it down on the ground , so you need either a mobile mechanic, or a mate or it's a  do it yourself job. Always put the vehicle up on stands, don't go under it just on a jack. Crack the wheel nuts loose before jacking up.  I know it's not the same but changing the springs is a quick job.  Release the shock  so the axle can drop  and the springs literally drop out, hopefully the gas bags  will be just as easy to do.

The van was originally taken off the road because of an oil leak into the coolant. Then 'It wouldn't go', so maybe it's the head?
It last passed an MOT in 2016 at 111000 miles. the interior is good as it's been used by an electrician rather than a builder.
However there was a 'crunch' when I was jacking up the rear , so some sill corrosion , lets hope it's not too much.

The plan is  to fit a 1.9td  XUd engine and run it on veg, I've already run a Xantia for 60,000 miles on vegso should be Ok , I'll probably have to fabricate up an exhaust, we will see. At the present time I need to get it up on the ramp and check it out, it could be too far gone ( hope not). A bit of sill welding is OK.

In 2018 I did win a van on ebay, down in Devon somewhere for about a grand, when I emailed the seller  ' Can come weds, can you pick me up from the station' I got the reply "Sold it to a door knocker  1/2 an hour before the auction ended for £450. Sorry" so I became a bit sceptical/ despondant about vans a long way off, at least this one was 'local'

#43 Re: Maintenance » Track rod replacement » 2019-09-02 01:34:44

That picture does make it clear.  When the rack was assembled on a bench it would be quite easy to peen it with a hammer and punch, on the vehicle it will be a different proposition.  You could fit a star washer which is a lock washer with lots of small serrations , or just loctite it together with , just 'nut lock' usually red  loctite, you really don't need 'bearing fit' or 'stud lock'. As long as its torqued up reasonably tight it should be fine, all the force is axial , there is no twisting ( undoing) torque.

#44 Re: Maintenance » Track rod replacement » 2019-08-28 01:45:20

Is that like a black ring wth teeth on the outside that clicks onto little grooves on the outside of the track rod?

#45 Re: Maintenance » Track rod replacement » 2019-08-27 21:04:51

If the lock washer is trashed upon removal of the track rods, you can be sure it will be available from the main dealer as a spare part.  You could just loctite them, but not recommended, the original lock washer is the way to go really.

I would bet a pound to a penny that either the cam timing or the fuel pump timing (or both) is retarded one tooth.  It's quite easy on these engines to get the slack  on the tension side of the belt rather than on the slack side, where the tensioner is.  I have done dozens of these over the years  both XUD and DW8 and it can be problematic to get the belt right. Especially on the DW8 with the floating pulleys.

Simplybearings do  oilseals at a very reasonable cost  dia and  cross section ( diameter) I had 2 Suzuki 'o' rings £1.75  , dealer £4.75 each. The sets you get are better than nothing, but the cross sections are usually to big for the appropriate diameter.  For £128 you could get a complete Xantia  and take the filter housing off!

#49 Re: Maintenance » ring and suspension bushes/steering rack bushes and rod end ball joint » 2019-07-09 12:34:16

I think the bottom ball joint/ lower arm join  is an example of very poor design. My Xantia ( and 405 the same) uses a taper and a nut. The nut of course  pulls the taper into its socket and its all tight.  Many PSA designs ( Berlingo, etc, etc )use a parralel pin and a pinch bolt, simple and no taper to break , so they can be easier to undo.   The dispatch/ Expert/ Scudo  uses a tapered pin in  split tapered hole , with a pinch bolt.  Unless the taper is pushed up into it's  socket when the pinch bolt is tightened, whats to say it is actually tight in there ( rather than the bolt being tight.) These are well known for rattling loose , some people have to replace the hub carrier as the hole is so worn the pin won't engage. The  taper pin has a waist for the pinch bolt , so it can't actally fall out , just rattle about .  I think it's a poor design.

I do have a Revue Technique manual for the Synergie/806. It is very comprehensive, but of course it is in French and only covers the older 2.1td, 1.9td and 1.9. It does cover very comprehensively the other aspects of the vehicles , clutch, gearbox, brakes suspension and so forth,   except the later engines. I could scan it one section at a time if there is any demand. It's several hundred pages so don't expect anything overnight.
