LT95 overdrives

[incisor]

i have a couple headed my way...

anyone have the original fitting instructions or manual for them?

i believe some had shims ? that needed fitting as well as the drive gear ?

TIA

they fit up the same as the series and lt230 style units.

shimming is for the support bearing for those that had them and to locate the output gear into correct mesh onto the intermediate drive shaft.

you loose the ability for a PTO with an overdrive.

I have emailed a copy to your private e-mail address - the AULRO system said it was too big to send.

The Isuzu will kill it.

The Isuzu will kill it.
yeah, have heard mixed stories on how well they cope.

time will tell the tale...

There was a thread on this maybe 6-9 months ago where the general consensus an Isuzu would kill it - but then someone put a post up in the last week or so who said he has been running one for a number of years and is still going strong.

I would have thought that if you drove it as is designed - 4th and maybe 3rd gear and no real load ie cruising on freeways eg it would likely last. However we are all forgetful and it would only take a lapse of concentration to kill it with and Isuzu.

I think there was also a thread quite a while back about plumbing in a better oil supply, or bigger reservoir, or something.

My experience of 2 overdrives on LT95 behind 4BD1 was both were expensive failures. I was running up the WA coast regularly at the time at speed in sometimes very hot conditions. The first was replaced under warranty, but the 2nd went just as quick and I gave them a miss after that. They run too hot at Australia hwy speeds - not enough oil I'd say. Both of mine lost the hardening from the gear teeth which went through the system and led to big-time transfer case failure as well.

Put a 300Tdi and 5 speed in it - much better!

BTW , it doesn't matter whether the overdrive is used or not. The output from the gearbox still routes through the overdrive and out again so the gears,bearings and thrust washer are still under load or vibration stress anyway.

i am aware of that...

will be nice if it handles it, if not then such is life..

i intend to try it tho...

not enough oil I'd say.

I am not sure that is the issue - the oil in the O/D and transfer case are one and the same. The O/D has two large holes with oil catchers which both catch the oil from the transfer case and feed the oil back to the tfr case. The oil capacity of the o/d it self must be somewhere about 1 litre - maybe more and when it is full it just flows back into the transfer case. Indeed to top up the transfer case you need to remove the tfr case and o/d filler plugs and refill through the o/d until the oil comes out the tfr case filler hole.

The only way I can see the o/d not having enough oil is if the transfer case is low and not throwing up enough oil to keep the O/D topped up - the o/d will push oil out to the tfr case but not be topped up by the tfr case.
