Stretching the spec for the BW's VC reisistance?

[superquag]

I have a spare BW transfer case, sold to me by a "LR Mechanic" as being OK. Son (who now drives MY car...) wants to put this 'good' VC in, so he can go beach driving.
According to Ashcroft, the starting torque is around 27 Nm, and should rotate 25 to 30 degrees after 1 minute pressure at 20 Nm. This one is more like 36Nm to rotate within the time-frame.

- Am I being too fussy?

and, if so

am I running the risk of loading up the rest of the driver-train?

I plan on either visiting the UK or having one sent out in 3 to 6 months (including output shaft...)

'95 Classic with working air suspension, - and RWD only...

If it's not seized or spinning freely I wouldn't be too concerned.
Are you running in 2wd due to the original being locked up?

Personally I keep my vehicles off beaches. Salty sand is pretty nasty stuff.

[superquag]

Yep, original died early in my ownership of The Lady Sarah... chirping on hard corners, taking the scenic route on round-a-bouts, all the usual symptoms of totally locked up. :mad:

The 'OK' spare I've got does turn, but needs a lot more effort than 'specified'. but it does turn... Just wondering how far I can push the boundries - and get away with it !:angel:

Have resigned myself to lashing out on a new VC (might have to go to UK to bring it back...) eventually, this is just an interim patch-up to keep #1 son happy and eager to maintain Sarah in the manner to which she is accustomed. Only needs to last around 6 months / 5000 kms at most.
- he needs it for work, but can't afford the petrol to go elsewhere...:Rolling::Rolling::Rolling:

Hmmm mine is chirping on hard corners, one in particular coming into the work carpark as it goes over some shiny paint on the road. That and the clicking coming from the front (CV?) on tight corners in carparks makes me think mine might be in a similar situation to yours...let me know if you decide to get one from the UK, we might be able to find enough people to do a group buy and get a good discount on postage an maybe purchase price????

Is that test done at a certain temperature? It seems okay to me.

Alas, the news is'nt likely to be good...:o. You can do the single wheel test.... or go for Gold and take off the front prop shaft from the box, and try and turn the flange... 30mm socket on the nut and a Very Long Bar.

I would think that your somewhat-stiffer-than-spec viscous unit would be quite okay to install, as far as I understand, a failed unit completely locks due to solidification of the fluid medium. How often do owners (or mechanics) of these vehicles remove a propshaft and time their VCs? I don't recall it being in the maintenance schedule. Surely won't be the worst part of a 20-odd year old vehicle.

[superquag]

Yes, may as well install it and see what happens...

A very small % fail in the 'open' mode, that is, zero or minimal binding, and the driver only finds out when he goes seriously off-road and gets ONE wheel spinning.....
The other 99% fail by totally locking up. This is very bad for road use...

The single wheel test is good enough to let you know what is (or is'nt....) happening. Only fussy folk like myself would consider dropping the prop shaft.....

Have been onto Ashcroft and Dave very kindly informs me that carriage for the VC alone is £57 and £77 for the Vc and output shaft. ($110 and $160 or so)
Weights are 6kg for the VC and 3kg for the shaft.

Just under 10kg excess baggage if one was to bring it back by 'plane.:angel:

Just keep in mind you'll be paying VAT if you buy them in the UK. Apparently there's a method to claim that back from Her Majesties Customs though.

[superquag]

At least with the mail order (o/seas) the VAT comes off automatically in the checkout section.
- Knowing my Good Luck, Aussie Customs will have a go as well...:(

[benji]

Lol, have to put my hand up and say I checked mine at the output shaft. ..

As mentioned most on line sellers from old blighty remove the VAT when you check out. Just don't use the ones that won't.

Yes but you can only be vat exempt at purchase if the parts are posted directly out of the country. If you collect in person then you pay vat even if you are flying out that day. You need to claim back later.
