What a load of rubbish, the D8H had pressure lubed final drives, mainly to feed the outer bearings, the 2U did not and would throw oil around in reverse as well as forward.
On the D8H the pump ran off the reduction gear if I remember correctly, now in reverse the pump would turn backwards so did it lube in reverse? I know we used to think it didn't but I really don't know for sure.

I was told by a Cat dealer technician who I was helping change a final drive lube pump on a D9 G, that one should keep in mind that while in reverse for a "long" distance, the finals would not be getting lubed.

[QUOTE=magneticanomaly;197789]I have D8 2U16403, patiently waiting for me to get around to bringing her the last mile home. She sits where she was unloaded from a trailer, was backing up my 19% grade and slipped out of gear. The neighbor driving her got her stopped before she went over the bank (no blade on), and I have been waiting to get around to fixing the brakes and maybe figuring out why she jumps out of gear, before I resume backing up the hill.
There are no adjustments for the interlock mechanism. Shift positions are controlled by spring loaded plungers. A swinging gate allows only one shifter shaft to move at a time. If there is a problem with popping out of gear it is due to worn or stuck plunges, springs or wear to the sleeve assembly that locks the plungers.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
