think of it like this. youve pulled the box out and apart wouldnt you replace the bearings at the same time ?

Interestingly, when my (LT95) gearbox was overhauled about ten years ago (about 200,000km), because it was getting noisy, according to the bloke who did it, the only part that really needed replacing was the input bearing, although it was nowhere near as bad as the one in your pictures. Of course, all bearings and seals were replaced while it was apart.

Would an overdrive even fit an LT95 behind an Isuzu? Aren't the ratios different between the Isuzu and V8 boxes? So an overdrive designed for the V8 LT95 wouldn't really fit an Isuzu LT95?

The LT95, in common with other Landrover transfer cases, is designed so that the input gear on the gearbox mainshaft is the same for all ratios, and effectively the overdrive just replaces this gear. So the overdrive fits all LT95s. I am not too sure whether the fitting is the same on the LT230 transfer case, but although the layout is similar it is definitely NOT the same as Series Landrovers.

My apologies to everyone, this is a very late reply and it is also Off-Topic and Off Forum (Isuzu) but is a reply to posts in this thread.

Someone is getting their Ps and Ds mixed up.

The Rover SD-1 has a live beam axle, which could in fact be traditional Rover style diffs.

The P6 Rover car had a "De-dion sliding rear end" (independant suspension) with a non-Rover style diff which looked a bit like a Salisbury (and may in fact have been Salisbury).

G'day Diana,
Your are correct, sort of. The 8HA sals in the Fenders etc is way bigger than the sals TYPE of diff in either SD1 or DeDion equiped P series Rover.(P6B etc)
The SD1 had a sals type of differential, looked like a XE falcon Borgwarner diff withthe watts link attached etc. As far as I remember, the ratios for the P6B V8 auto were 3.07:1, and the Manual 3.36:1 or similar. The SD1 was I think as low as 2.88:1 for the auto,(Trimatic or BW 35/40/65)and around 3.36 for the 5 spd.
The Banjo type Rover diff wasn't fitted to either SD1 or P6 series, but WAS fitted to the V8 and 3000 Coupe P5 series. These were 3.54 ratio and were basically an early RRC diff centre.

JC-on- Holiday...

In the ACT at the moment, heading for Dubbo and Sapphire soon!!

about the quickest ratio I know of in a diff is about 2.6:1 but its not all that tough. and I wouldnt put one in...

that said Im not into speed and Id be going the other way running 4.7:1 and just taking my sweet time since my plan to liver forever is thus far right on track I reckon I can afford to slow down.

You can get 2:1 by mating an Albion truck diff. centre from a hub reduction Albion into a Toyota Dyna housing. Not too difficult. Bit of lathe and drill work.

Hot Rodder after market gear suppliers have a terrific range of C&P's for 9" & other Fords, Dana, and GM diffs, from low 2's up to 9's.
