Help for Changing Muncie Gear Oil

[Ralph E.]

This might help others.
This little project has always given me trouble as I could not get the suction gun tube to the bottom of the gear case.
Today I found a new method, (new to me anyway).

Changing gear oil in muncie M20 four speed.
1. took the suction tube off the suction gun and placed the tube out in the hot sun to soften it up.
2. cut off about 15" of a coat hanger.
3. put the coat hanger inside the nice soft suction tube.
4. bent the coat hanger and tube to about 140* and inserted it into the transmission fill hole.
5. tube and coat hanger go right in to the bottom of the gear case.
6. while holding the suction tube, pull the coat hanger out and leave the suction tube in place.
7. connect the suction tube to the suction gun and draw out the old gear oil.
8. when filled disconnect suction gun from the suction tube and empty gun into waste container.
9. reconnect gun to tube and repeat steps 7 & 8 until gear case is empty.
10. filling is simple, no explanation is necessary

That is a neat trick!

Me, not really a numbers guy, I just tapped and bushed a drain hole in my 69's M-20.

1970-74 guys get a pass on this. They already have a drain plug.
