LT95 GEARBOX OIL MYSTERY
Muir, Lance
LANDY GREETINGS
I have an 110 with V8 and LT95 gearbox that is pure joy, the only issue is I need to constantly fill the main gearbox with oil, and when checking the transfer area the oil floods out the filler plug hole when removed, there is definitely oil moving from the main box to the transfer box. As can be seen by the attachment it seems to be a common issue. Does anyone have experience they can share. The questions I have are:-
1) Could it be the ”output spacer” as mentioned in the attachment??????
2) Is it a seal?????
Any and all help greatly appreciated

Have the same problem with mine. I think it has to do with the seal between the two boxes. Bernard Cohen can advise us on this I think. What is the alternative solutions?

Hi Lance,
I have had a LT95 gearbox rebuilt 3 times and another one was rebuilt with the incorrect gearing put in which made the vehicle a dog to drive until I decided to put an R380 in the vehicle. On my 110 bakkie I still have the LT95 which has never let me down so far. My humble opinion is that these boxes are over 30 years old and components are tired. There is definitely a seal between the gearbox part and the transfer part of the gearbox which the latter is one unit and doesn’t split like other boxes’ did not find a part number for the seal in my parts workshop manual but I suspect it comes in the complete gasket kit which is available with these gearboxes. It however I suspect needs a major overhaul to fix this seal so one must way up the costs involved. I have always found that there is a “leak between the oils” of the gearbox and transfer in mine but it hasn’t been excessive when servicing. The oil is very important in my experience and normal engine oil 20w50 has been used in my gearbox LT95 all the years. The transfer box I have used diff/gear oil 80w90.In the manual they say use engine oil throughout but I chose to use a thicker oil for African climate. If I were you I would first try that small pipe conversion between the boxes before trying the major stripping, that is if the gears etc and box is still working ok.If you rebuild make sure you are not conned into taking Range Rover boxes to put into Defender 110’s as there are many variations of the LT95 as some were made for Rangies,Forward Controls,110’s ambulance’s etc,etc all with differing combinations. My bakkie has different gearing to the 110 station wagon and for this it came out as well with a Fairy overdrive which makes it fantastic to drive. I always like/liked the LT95 as the gears etc seemed so much stronger than looking at the newer boxes.
This is my 2c worth.
Regards,
Bernard

Morning Bernard
Many thanks for that great and impressive input, I really learnt a lot.
My 110 I believe is a 1986 model and original still. I am planning to put a overdive on the box soon which they tell me helps on the open road. Off road she’s a dream, The last time we saw each other was at the anniversary where I still had doty the green series 1 SWB,I sort of traded her in for this 110 see attached pic, I needed a LWB for fishing and camping and have been extremely happy with her, done a lot of mods and fitments. I was clued up with the old series boxes but the LT95 is a bit different.
Any once again many thanks, hope to seen you again soon
Keep well
Landy Regards

Looks great. Same as my station wagon with wind up windows, My bakkie is the 1985 which still has the sliding windows’ not sure if yours has a galvanised chassis which was done by AAD on these models when Leyland left SA.Mine has this chassis and I am sure that is why it has lasted all these years with the hard labour it has endured.
Muir, Lance
That’s interesting, mine has wind up windows, series type door handles, galvanised chassis. Due to a long story history nobody could tell me what year it is and its papers don’t say , surfing the net I could not find finer details.
