View Full Version : '89 Pajero Gearbox dramas
24-04-05, 11:18 AM
We ripped the box outa my mate's 89 turbo diesel Pajero last night & if anyone is familiar with these things they will know it hasn't been it's first rebuild.
I have heard the later diesel ones don't screw up all the time, which one is the pick to put in?
How about from behind petrol motors? How different are the ratios?
I've tried to justfuckinggoogleit but I've been wading though heaps of crap - is there a good 4WD forum I could ask on perhaps?
Cheers & beers
see if Mark's 4wd Adaptors has some sort of conversion kit. Check them out at www.marks4wd.com, otherwise, give them a rin & I'm sure they'll give u some advice

The models we are looking at apparently bolt in - I need conformation of this and the ratio differences.

I've got a 5 speed & a 2.6 petrol motor (motor stuffed, gearbox OK, clutch & pressure plate can't be too bad, about 2 yr old) from a 95 4wd triton sitting in the back of my ute at the moment. Am going to drop it off at a mates place in the next couple of days to be stripped & turned into mechanical arty type stuff he sells at the markets.
Dunno if the gearbox is compatible with a 89 pajero. (that's your job to work out). If any of it is any good to you, speak now, or forever hold your peace :)
THis is from my understanding...
All of the 4Cyl & T/D Gearboxes suffered from 5th gear problems (this was especially the case if the Pajero was used for towing regulary - the problem was the 5th gear nut used to work loose and evently allowed the box to destroy itself if not stripped down and rebuilt..
The NA and NB series Gearboxes used to have bearing problems - they were just too small and lightweight for their intented purpose and they used to break very easily
The NC to NE series had Synchro problems and if driven reasonably hard, or given extra power/torque, used to last a very short time.
The NF and NG are the pick of the bunch - provided the 5th Gear problem had been rectified early enogh, they were quite robust.
There were two Diesel gearboxes to chose from - One is physically larger than the other and was fitted to the Intercooled Turbo Diesel models. This is the one to look for if wanting a replacement... I am told if you crawl underneath a Intercooled model and a non intercooled model - the difference is quite obvious to see so they can not be confused. I am not sure if the belhousing is identical (I assume it would be as it's the same block, however I am told the gear lever is different, (larger/thicker) so you may need that also..)

Cheers for the reply Southo, but it looks like Bitsamissing has hooked us up. (cheers bloke) Hopefully being a 95 petrol box it's more reliable than the 89 non-intercooled TD box.
If we get any more drama's, we'll have to go for the bigger animal.

Did he put it in last night ?, is it same or not ?
EDIT: Ash, Just talkin to him & picked up the bits he doesn't want. Clutch actuation/fork assy is different, his hydraulic, mine cable. He's swapping all the internals over to his case. all looks to be the same inside. it had better be, 'cause I can't give him back the bottle of bourbon :p . well I can, but it wont be in the same form as when he gave it to me :D
