|
|
Hi Guys
Am I right in thinking that the transfer box and gearbox (M38A1) share the same oil resevoir. I have just drained the transfer box then removed the plug on the side of the gearbox and nothing came out. Gearbox is free of chassis so I tipped toward side drain but still nothing came out.
I thought I read that the boxes share a common oil resevoir, just want to be sure before I send of for inspection and re-build?
Many thanks
Nic |

They do not have common oil reservoir, but there is a problem known as oil migration between t/c and gearbox. Drained the oil from two jeeps yesterday, one had normal oil level in both if slightly low, but the other jeep had a low level in gearbox and higher in the transfer case. There are special bearings available to stop this problem. |

I thought I had read that the lube is common between the two boxes. I believe there is a 1/2" hole to the side of the bearing that the lube can migrate. I think it is meant to be that way. _________________ Brett

Ya Wes, as I stated, "I think". I had to give myself a way out of that statement. . _________________ Brett
