This has probably been discussed somewhere, but here goes: on a TT rear end where there is the square plug at the top of the plate at the end of the worm gear, when I open it up should I be able to "feel" any lube oil much like the differential plug? I suspect not, but just want to make sure. Almost has to be open to the diff somehow, with that worm gear spinning on top, but want to make sure it's kept lubed. Safe to assume the diff oil follows around the big ring gear enough to keep the worm properly lubed? That worm gear box felt fairly warm after a 6 mile shakedown run. How warm should it be? Wasn't hot, but fairly warm. Could keep my hand on it pretty much forever, though. Thanks
The early TT rear ends didn't have that plug at the top-rear of the axle housing cap. The only openings were the plug on the right side of the clamshell to add lubricant and the drain on the bottom. The upper plug was added later to assist in adding lubricant more easily.
Just remove the axle cap plug (the one on top) and the plug on the side of the clamshell, add lubricant until a little starts to come out of the side opening, then put both plugs back in place. You're done.
As the ring gear spins it slings oil everywhere it needs to be. You should NOT fill the housing to the top.
I never noticed (because it never occurred to me to check it) how hot the rear end gets. The next time I take it out I'll check it and report.
That'd be great. I know I'm being too picky, but since I'm still in the "learning phase" (which never really ends, does it?)....just curious to compare to others as best as can be done in print. Be nice to have two side by side to feel. (reminds me of my high school days with chicks!)
