Anybody have experience with an 89 range rover and the vicous drive in the transfer case or any other comments with this model.
Thanks.

My brother has it in a 90 . It is from an LSE range rover (The longer one). So it is a 4.2 engine with the auto box and transfer box. Just took the lot out and dumped it in his 90. see below


BTW with the Invalid bit . i had that problem untill some members on here told me to clear my cookies fie and since than it has been fine, and as you can see i can post again. So cheers to you all.

I have a 92 and LOOOOVE my Borg Warner.
On rock steps I seem to be able to get as far as mates . On sand they seem to be not quite as good as an LT230.
But they are quiet and NO clunks at all. It makes the car much more refined on road. Although I miss the old kerchunk, kerchunk, when you pull up in low range.
They seem as reliable as the LT230 and a new VC is not too expensive from UK.

The Viscous coupling is okay, but I like the LT230 for my style of off-road driving. The parts for the VC like Phil A have mentioned are quite affordable from the UK these days and the actual costs are more affordable.

Yes the VC is smooth, quiet and there's no clunks, they do have shortfalls if you push them (and I know how to push stuff don't I Vlad [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img] ). I used to find in my 93 that the VC would take time to engage (or lock up) and sometimes it wouldn't at the most inapropriate time.

Being the short fused type with crap that doesn't work, I gave it the big A and put the LT230 in. The VC is good for 'touring' type off-road, but push it a bit on rocky or any sort of 'real' 4WDing (especially ascending any sort of inclines with plenty of uneven ground or cross axled type stuff) and the VC allows the front wheel to spin aimlessly with little drive transmitted to the rear on none at all. I have seen only one that works in all the years in the RRC/BLROC but most don't work as they should.

But that's my opinion. I like to actalluy 'select' what I like (I have the same opinion regards to ETC on the Disco 2/3) not have compontent decided for me.

Good luck with it, hope I didn't throw a spanner in the works for you, just speaking from experience.

Interesting coments aquarangie, I agree with you on having the control. There is more reasoning power in the human brain than a lump of viscous stuff. Any coments on my other posting (manual box).

Peter de Quant from Range Parts believes they are unreliable and will (not "may") fail.

He's an LT230 man.

Er Trav,
I am afriad I have to disagree with your assessment of the BW transfer shortcomings on rock steps. Your response about rock steps is contrary to my experience , so I thought the whole thing through for the first time. I now have a headache.
Its important to realize that a BW transfer is ALWAYS DIRECT DRIVE to the rear wheels. The front driveshaft cannot turn faster than the rear under power as there is no centre diff to send power to the least resistance. Thinking about this , I think that is the reason also that VC Rangies are a bit iffy braking in reverse, the VC allows some front axle slip so the rear brakes are doing all the work.

The only fault a BW tranfer could give on rocks etc is that the front wheels just sit there doing nothing if the VC is stuffed. They cannot take power from the rear.
So your problem on steps was simply one of left to right traction , ie one front wheel had traction and the other didn't so power was transferered to the one that didn't.The fact that you had wheelspin meant that the VC had locked up or was working properly..
Think about when a VC seizes. the car is locked in the equivalent of difflock. So a BW transfer is like an LT230 in difflock with a little bit of slip allowed to enable the car to turn corners.
On sand of course, the VC can slip a bit so the front axle is not pulling its entire share, maybe only 90%, although the VC should lock up quickly due to heat generated.. This is enough to have the rear wheels sink a bit, maybe an inch or two.
So Vlad the BW is the ducks guts. the only reason the were not put in Disco is cost.
