Remember that Maytag used 34 ounces to fill the transmission. That's 2 more ounces than a regular quart of oil. Probably doesn't make a difference especially in an orbital, but just throwing that out there.

Not to dispute qsd-dan because I have tremendous respect for his Maytag knowledge, but I have found that filling a Maytag helical transmission to the top of the bottom half uses slightly less than 32 oz. of oil. I always seem to have a little left in my quart-size bottle. Maybe I'm doing something wrong?

What year transmissions are you working with? Pre 1966 transmission used less oil and you'll have several ounces left over. I use the leftovers for lubing brake packages and damper pads on pre 1966 machines. All of the 70's and 80's transmissions I've rebuilt took a full 34 ounces. Maytag did minor modifications to the late 60's transmissions, one of them was reengineering them for slightly more oil capacity. I only have one post 1965 Maytag washer from the 60's (1967) and haven't cracked open the transmission on that yet. Still trying to get the damn 8 finned agitator off of the shaft without destroying it.
