Yes. I'll put it with the others. :brushteeth:

I don't have a recon vcu. I have a NEW vcu. The real thing.

Regarding wobble, the metal is far heavier than the fluid inside. If a recon vcu isn't welded inline then this can create a wobble effect. I don't think the fluid is heavy enough to make a difference. The differing plates move it about anyway.

A har....I thought you had a recon.....so you have an origional GKN. ..from main dealer i presume??

Mine was reconditioned using some "new and improved viscous fluid" i really wish i knew what that mixture consists of :(

but i have no reason to believe it isn't true because it was done by a very reputable company near me :)

This is what some of the vw guys say.....Usually the fluid lasts for around 70k but with additives they can stretch this out to 160k.......just need to find out what these additives are...

I would love to see their test rig. The one thing we focus on is measuring the resistance across the vcu (and arguing about it) during normal running. The abs and traction control rely on the properties/ability of the vcu to assist them to do what they do best. The vcu has to "react" to what's happening by "auto sensing" what's required to assist traction. The vcu has to control it's resistance across itself to allow enough power to the rear for the traction control to pulse brake 1 spinning wheel with the abs, so power can be delivered to the wheel with grip, if 1 of the rear is spinning. If both rear wheels are spinning then the vcu needs to supply power to allow the abs pulse braking to be effective.

I would love to see the test rig and results to that one...







so I would copy the rig. :)

Not from main dealer. They is much more expensive. There's a number of retailers online who advertise and sell genuine new vcu's.

now that would be useful :)


but i doubt they have one tbh
 
Yeah he's about 16 secs for his 8kg but with mine being a rough setup and not quite gone the full movement etc just wondered if it looked about the right movement from the vid..
 
on the subject of vcu a friend of mine has a td4 minus the propshaft and altho he never told his insurance when he first insured it its now up for insurance renewal and he has told them they now wont insure him with out the prop fitted tried a few different insurance companys and they all said no and we don't have the prop to refit also dubious about buying a second hand 1 for the obvious reasons
does anyone know any insurance company that will insure it ???how about Adrian flux??

getting a second hand prop is ok ~~(check the VCU) however the chances are the motor was sold like that coz the VCU has damaged other components (IRD) etc.

fix it proppa - or buy a car.

Ok hippo n hat man I've done a rough rudimentary test with what I had to hand and on my Todd (which wasn't easy lol) here's my result

http://www.youtube.com/watch?v=nuOgmCLtyfo

How does that seem to you? It's roughly 12 seconds with 8 kg on a 1.2m level...

Yer can have a cookie fer performing the test.

From what I see the bar is already moving slightly and travels nearly 45 degrees from 0.06 to 0.18 second. So that's nearly 45 degrees in 12 seconds. so yer probably looking at something like 14 or 15 seconds for a ful 45 degree turn. That would be a value I would be happy with if doing a one wheel up test on my hippo.

But, there still remains the question as to why yer vcu isn't warm after a short trip. The one wheel up test has shown one prop stationary whilst the other prop is turning during the test. That proves yer vcu has a resistance across it, but not too much that it doesn't allow it to turn.

The turnip test (measuring temp before and after a drive) should result in a vcu temp which is warm to touch. Measuring with an infra red temp measuring thing is the easy option. Take the temp from the 3 inch circumference part of the vcu after the Freelander has stood stationary for a while (will be ambient temp same as the door metal in the shade), then take it for a drive of say 4 miles, then stop and measure vcu temp again.

I have trouble with companies like the AA who won't insure me as mines been re-imported and I have what they consider to be "aggressive" mods like a stronger sump guard. Despite this not bothering them some years ago, they won't insure it now. So I use Adrian flux. Not everyone on ere is happy with them but that's life. It's a good job I didn't tell the AA about me hellfire missiles.

Edit: due to replying to the wrong post. :doh:
