Thread: 95 classic drive train

I stand to be corrected but I think the 88 transfer case is gear driven and the later ones are chain driven

trans case went to viscous didn't it

the viscous coupling sounds familiar, and if so thats what I am interested to know more about, good and bad. Does it still have the diff lock? How is the off road performance? reliability? etc

The Borg Warner VC transfer cases I've always been a bit of a critic of them but maybe there's something to be had with them. Refined, quiet, smooth and they do work well although sometimes they do have a bit of a delay to kick in which I found on Aquarangie. I changed it to a LT230 because at the time it was much cheaper to be quite honest, but at the end of the day the LT230 is still a positive diff lock and that's where it wins out.

Also the parts are getting cheaper too compared to last time I had one, can be rebuilt for about the same cost of the LT230 these days if you scorce the parts from abroad.

of course...........viscous

Thanks guys, thats good stuff and pretty much as I remember.

Aqua, can you elaborate more on the mechanics of how the VC works if there is no diff lock?

Is the auto still a ZF in the 95?

I would be keen for offroading in the classic so would be interested in how the VC does perform under those circumstances..

Any experience or advice would be great!

Thanks

Up to 1984 model, they all had the LT95 4 speed the same as the Stage 1 Series 3 etc. (Some people call it the Ferguson box, because of where the design came from.)

From Phase 2 the "1985 model" they had either the LT85 5 sp manual or Torqueflyte 727 auto all on the LT230. This was subsequently changed to the ZF auto on the LT230.

The Vogue SE's had the Borg Warner chain drive T/F with the viscous coupling.

As mentioned by others the LT 230 is in my opinion the better transmission although not as quiet as the BW transfer.

You can easily tell which transfer it has, the LT230 looks like the regular t/f box where the BW has the epicyclic box (hi and Lo transfer) as a big protrusion at the rear of the mainshaft. (see pic)



Addit: The ZF 4 sp auto started in the late 1980s and continues through the D2.

The "viscous coupling" is a sealed unit which contains a thick "viscous" fluid that allows a minimal amount of variation between the front and rear outputs. As opposed to open diff design it will still drive both front and rear even it traction is completely lost on one axle. They are not a positive lock so you do lose some traction but it is idiot proof for Toorak Tractor set. It is not favoured by the 4WD enthusiast set.

The BW VC works on heatNot a CDL but similar result. They tend to wield them self in some cases. Then are hard on tyres,CVs and Fuel. Easy to replace. 30mins aprox. Lt 230 are more reliable in long term if well lubricated.But if they sh_t them self $$$ BW VC is softer on runing gear when working as it should.
