Engine and Gearbox Oil

I ran my 2H in my 87 troopy up to 350k on the recommended oils with no problems and the engine was still going strong. I changed it every 5000 religously. It wasnt the 2H-T turbo though. I imagine there are some higher temps envolved ?
If the gregorys manual saids grease it I would !
If not fitted install the breather pipe kit between the transfer case and gearbox. You may or not be aware that the seal between the two is not a good design and you can pump the transfer case dry into the main box.
Also watch out on the pressure relief valve siezing on the oil system. A sign is an unexplained oil pressure rise on the gauge.
Also watch for rust developing behind the rear side body badges.

Bloody good tough old trucks though !!!

Happy motoring ; )

Hi Ben & Bridget,
I would recomend BP Easy shift for the gearbox oil, it will stop all the gear crunching when cold. As for the water pump, their are no grease nipples on water pumps, I dont know where Gregorys got that one from.

Just use standard diesel engine oil 15W40 for the 12H-T. Its one of the strongest motors ever built. I used to change mine at 5k but since its direct injection, higher intervals can be OK.

Gearbox - get cold gear change problems with most 80-90, so I found 75/90 was good - Valvoline Duragear was what I used.

The water pumps are a cheap replacement item - about $75. There is no grease point on them.

Cheers
