Perentie LT95 Hand Brakes

[123rover50]

I have two LT95,s here with two different linkages.
One is a cable exiting from the bottom LHS of the backing plate and the other is from the RHS hooked up to a linkage bolted to the box.
What were the different applications?
My old 110 has the small drum brake and I was thinking of swapping one over.

The smaller from is from an early Range Rover I'd say.

AFAIK the Rangie was a smaller dia but longer handbrake drum with mechanical leverage off the transfer box & the 110's were cable linkage. You need to be aware that prop shaft lengths will differ between them & also I believe the 110 unit is more capable.
Are talking of swapping the whole box or just the handbrake assy, as the ratio's will be different. I have a chart somewhere that shows the LT95 ratio's & serial no's.

I may be wrong, but didn't early range rovers have the same high range ratio? I recall my landy mechanic showing me the parts diagram and the different T/C ratios, and a particular RRC had the 0.996 as well.

Although I am a male and have a poor memory haha.

I thought the more common factory high range ratio on the RR v8 3.5 with LT95 was 1.113:1.

You may be right about how common it is.

Here is more info I found after a quick google:

Pretty sure the rear output housing is different for the smaller drum, and propshaft is same length.

smaller drum is rangie larger is county/perentie (roughly there is some cross population especially now that theyve been had at by people who want the other than what they were fitted with)

its a bolt over conversion but you need the output housing and linkage assmblies. If you have the 2 boxes side by side its obvious and easy, if you're looking at a parts book its less obvious what you need.

from memory the ratio change from the advertised 1.00 to .996 came about from a change in the gear design and the primary gears dont interchange but I've never personally been caught out with an odd bod box, ordering parts by the case id numbers has always worked for me.

[123rover50]

Sorry, I did not make myself clear.
Yes the small drum on the 110 is the same as a Rangie one.
The other two are both Perentie large drum but there are two different mechanisms. One a cable from the bottom left and the other mechanical from the right. I can grab some photos tomorrow if needed.
Just wondering what the different applications were.
Which would be the easiest to swap over to the 110.

Keith likely the linkage type one maybe from a stage 1??

I bought the two boxes off Grays auctions. Both ex military with PTO,s and TRB shafts etc.

What you have is an early 110 LT95A with the rod that comes out of the top centre of the backing plate and a later type with the cable that comes out of the bottom centre of the backing plate. This one has the cable that attaches to one shoe and works better than the earlier ones. If it's in good nick I would use it Keith.

Spot on Steve. Rear output shaft and propshaft is the same irrespective of what housing is on it.

The one with the rod on the top is from early 110 build and the one with the cable from the bottom is from the Bushranger build ones. Put the bushranger one on.
