LT95 tapered roller conversion

Tony thanks for your reply and you are not on my ignore list
The situation is this I have an LT95 in good condition but the backlash is giving me the ****$. Someone offered me an LT95 TRB conversion tonight but im not sure it is the answer to my problems or do I need to change the gear ratios as the conversion is from an Isuzu
All was well until I installed the Detroit but at the moment I am trying to ascertain what the problem is the Transfer / Rear Tailshaft / or the Detroit.
I cant see the Detroit install being the problem as they are really a Soft locker install that dont change the diff backlash.

Thanks

Hi Dave not according to my book (open in front of me) all 4x4 T/C are 1.123:1 high range
3.321.:1 low range
All 6x6 boxs had the same low range as the 4x4 (3.321:1) but there high range was 0.996:1

Thats good to know....mate the locker wont induce back lash in the T/C

thats one of two things worn shims on the intermidiat shaft or worn shims (spacers) on the gear wheels in the center diff...if you have the opertunity to change to a TRB set do so there much better and when your changing that re-co the center diff..both done without takeing the box out...I used to set that a bit tighter than the book recomended and it was much better
PS for got to say I ran the TRB out of a 4x4 in my 3.5 & 3.9 rangie and it was great

might want to update that book....

or I might want to get my head off of the lt230....

Ihave the ratios wrong but the vehicle types right.

theres the .996 and the 1.123

substitute those values in my previous posts.

not all mill 4x4 LRs are .996 weve got a dozen on base that arent...Im fairly sure the 6x6's are 1.123:1. But I dont got a 6x6 book in front of me.

I need a holiday....... or a week where nothing goes wrong...

I tought i read somewere that what tony has posted was right as the 6x6 run the .996to1 high range as they still run 4.7 diffs thus needing the .996 in high ..

Also all civi 4bd1's got the same .996 high so they could cope with highway speed ....

And id take a good punt as to say that maby all defence LT95's are of the same raito being .996 to 1 :D:D:D:D

Heres somthing worth a read LandRover Perentie

Dave all 4x4's should be 123:1 high and 321:1 low, if you have some at work that are not,well you should'nt have as you would know they should all be the same accross the fleet...what level workshop are you?

Tony

were as deep as it gets, we have the abilityto rebuild if needed but thats under review now that the armys coming to the base.... which sucks because everything we were ment to get to be able to support the bus master looks like its going to be put on hold.

So your classification is a Base workshop?

have you got access to "Mimms" (I suspect SDSS is no longer working)

Tony

If you're worried about the intermediate gears, take the bottom cover off and have a look. It's easy enough to do and when you drain the oil you'll be able to check for any bits. If all's well then at least you'll know it's not the cause of any backlash.

Davo, its not that easy, there shimed with phrospas bronz shims so un less you can slide the gears on the shaft (and its gotta be very bad to do that) you may not pick it up,and when the shims wear it comes out with the oil as a gold'ie fleck in the oil no bits..
