Concerning Transmission and Transfer Case Rebuilds

[Phil Waterman]

Hi All

If you are rebuilding a Transmission or Transfer Case or for any reason have it apart and clean of gear lube out of all the bearings and shafts, remember to check the fluid level again after driving the vehicle a short distance.

Reason I mention this is when I rebuilt my HUP I prelubed (wiped all bearings with gear lube) transmission and transfer case but did not fill them with lube until they were painted. When I filled them up to the correct filler hole I then took the truck for a drive when I came back check them for leaks and pulled the plugs. The gear lube level was way down from what it had been an hour earlier.

This has never been a problem when changing the gear lube, suspect what is happening is that the gear lube is thick enough that it is not filling all the bearings and shaft spaces as it first goes in giving a faults full level. A little drive time and the spaces get filled.

Just a thought to stick in the back of your mind.

Cheers Phil
