Yung bloody wippersnapper! Yu aint too old to have ya arse tanned- tha knows! Wheres my belt?

Kitchenning, :( - want to get it sorted before hols. Yu guys are orf laning agin int ya? Hope to be out and about soon with my "temp motor".
 
I drilled two 6mm holes 180 degrees between them on the outside of vcu filled with
degreaser left it for half an hour,blew the silocone out with compressed air. Replaced the silicone with Moreys grease. Sealed up the holes with knead it filler.It has taken the
load off the IRD.I will take it off road and check its off road capabilities.I realise that this
is not the ultimate cure but I thought I would give it a go

mines a temp motor too....temporarily works !

Did yu check the viscosity of the silicone? It appears it is critical to the VCUs operation.
 
I did not check the viscosity of the moreys grease .It is certainly very sticky.My main
objective was to take the load off the vcu
 
what I am trying to get to grips with is.......

If yu havent checked the viscosity of the Silicone fluid , or the grease, how do you know its characteristics under load and therefore the affect that it will have on the transmission components.
You do realise that the silicone fluids shear characteristics change depending on the load going through them (heat I think) thereby altering the transmission characteristics within the VCU. What makes you think that "Morey's grease" is a dilitant fluid - coz I can assure you that it aint - it has similar characteristics to any grease, i.e. as it gets hot, its viscosity gets thinner - the silicone fluid has a viscosity gradient the reverse of oil, i.e. it gets thicker, imparting more drive though the VCU!:rolleyes:

For your information..
Morey's Grease
BASE OIL VISCOSITY (Typical)
cSt @ 40 ºC 115
cSt @ 100 ºC 12.2

Have you checked whether the VCU locks up when on slippery surfaces? have you checked whether it doesnt lock up under normal driving conditions? Have you filled the requisite amount? The volume of fluid in the VCU is critical, as is the expansion characteristics.
I believe that by changing for a different fluid with unknown viscosity and shear characteristics, you have just "hoped for the best" :doh:. You might just as well have left no fluid in the VCU, or have removed it completely and gone "Mondo" mode. Sounds like a complete waste of time and space to me, unless you can demonstrate some reasoned argument as to why you have chosen this particular medium, etc. What you appear to have created is a "reverse VCU" with the characteristics of... when cold it locks up and when you get slippage in the drive train it stops transmission to the rear wheels. Fantastic bit of kit! Completely useless, but I suppose it stopped you driving your Hippoo for a while.

By the way - if yu get involved in an accident, the chances are, your insurance is invalid anorl :eek:.

Hats off to Hugh Bathe!

Any mod is worthwhile, in this case, purging the VCU of its silicone and replacing with A.N.other is a challenge in itself.

How much fluid was removed?

The grease wont act as silicone would, but at least it will stop the plates binding or seizing up.

It could also be a mod to get round MOT requirements ;)

Well done that man!
















As for insurance, they won't have a notion what has gone on.

no, NO! Any mod is NOT worthwhile. Sure it is good that Hugh is looking at this, as many have done in the past, but enlighten me - what has been achieved? Nothing constructive! You cannot be sure that the plates wont seize. Can you assure me that the system wont overheat, because the plates are constantly in shear? the plates buckle? of course not.
As for MOT, I think that if the VCU is removed, it doesnt affect the MOT.

I hope you aren't, on a public forum, advocating that any mod, if the insurance companies cant find it, irrespective of safety implications, is OK, N.I. Thoughts of dead children in a river spring to mind :eek:.
 
Re: insurance,
'Act of god' I believe is their favourite get out clause.

If a VCU happens to be spent of fluid - act of god

Besides, Hugh would only be driving on private roads and off road, aint that right Hugh?

In NI the full shaft is needed for an MOT, of those suspect garages on the mainland UK, I wonder how many would be 'fit and proper' when presented with a vehicle that is void of the shaft!

re;torque test
hi gazza666
I have tryed the test and wheel turned at 140nm .Did i have to take freelander for a drive first as on some tests.Could my viscous be on the way out? f.l has done 63,000 and is a 1999 mod.

If you have read the previous posts 140NM is the highest we have had so far
Not sure if this means it’s on its way out we need more tests done by others to determine this
I never took my fl for a drive first before I made the test
might make the test worse by warming the vcu up
Does your fl feel tight when on full lock?
has not done many miles for a 1999 only 63k seems a high reading of 140NM
 
OK Fitted a second hand IRD a few weeks ago,..Today I fitted a new VCU,.When finished i thought i would try the Torque Test,,.

This is a New VCU No driving done prior to test..

Set Torque at 100LB and it clicked no turn..:mad:
Set Torque at 130LB and it clicked no turn..:mad:
Set Torque at 160LB and it clicked

160 is the highest mine goes,.but if i keep the pressure on the rear wheel does turn and it moved the tipex marks i had put on..:)

Also i still get the tightness on full lock..:cool:
 
I was expecting a new one to give a low reading relative to a used one like Gazza's for example.

Is it new as in new or is it one of these recon units? :)

Aren't you worried the grease might "overcook" & start to gum things up, I know I would be & don't feel too sure about this mod.
