    Re: gear boxes 82-70's

    For the sweep and table motors, I usually set a coffee can or whatever your going to catch the oil in on the lane. Then I take a rectangle piece of cardboard and fold it into a "V" shape to create a spillway for the oil so that it gets past the drip pan. Then I mount the piece of cardboard under the drain hole so that it has a downward slant and let the oil flow down the cardboard and into the can.

        In answer to your question:
        Have someone else do it.
        Put a clothespin on your nose if you're doing it... the oil stinks like a$$.

        But to be serious...

        Ours have the steel plug removed, and replaced with a short straight pipe nipple and a threaded cap. The pipe extends out over the drip pan. We just unscrew the cap and put a regular oil-change (reservior) pan and a funnel under it, or stick a piece of hose over the steel pipe into a bucket if we're flushing them with kerosene.(pour it into the top hole and let it run out the bottom)

          My way:
          DON'T leave it on the machine.
          Yank it, clean drip pans and other areas that are covered by gearboxes.
          Set drain plug slightly over edge of workbench and put a bucket on the floor. Then drain.
          While draining, blow out "fuzzies" with air hose, inspect seals.
          When drained, pour in a little kerosene or MEK and slosh it around inside (turn gearbox upside down, etc) then drain. Lather, rinse, repeat.
          When clean, refill. Put back on machine, taking care to clean output shafts and re-lube combo output splines.

          It aint worth doin' if it aint worth doin' right!
          It sucks to replace a table drive shaft just because of worn output splines from lack of maintenance. Also, it's good for bulky arms that impress the ladies and aid in armwrestling!

            MT has it right. You should always take your GB's off the machine and then drain the oil.

            What happens when you find brass shavings in your drained oil? Then you have to take the machine off and apart anyways right? In any case..you should always change your seals/gaskets and inspect your gears when you change oil.

              If you take them off the machine to drain them, you can set them in a large coffee can. The combo motors will sit just inside the lip of the can and won't fall over as long as no one bumps them. Back ends you lay flat on top the can but they need to be balanced or supported.

                I say leave the table gearboxes on.......otherwise you have the shaft alignment probs. mentioned in the table shaft thread.....take the sweeps off....not the table.

                  <font size="2" face="Verdana, Helvetica, sans-serif">I couldnt agree more hey, what a few more minutes, when ever we change oil etc we strip em down to inspect the condition of gears and the casing etc etc , when we do that we just rip one off and put another straight on that way the lane can be used again while we work on the gear box.
