The computers have to reset in a certain direction.
I am not sure if the reset handle screws on like a 60 or 70...
if so, the handle HAS to be on a certain side of the computer,
or it will unscrew.
All the controls; reset, on-off, hose is on one side
No other pump except a twin would have this problem.
The left side bezel of front and back should have these view holes.
Note in the pic the computers are backwards to each other, this puts both of the totalizers toward the inside
and the reset works the same side of each computer. The side totalizer is just below the reset coupling on the side of a computer.
The window on the bezel is in the corresponding location.
These computers both have the notch in the variator for the longer 40-A faces.
The computer on the left is a 1935 the one on the right is a 1934
ORIGINAL WAYNE 40 COMPUTERS WILL NOT WORK
I will say this, I bet it was a B*tch to read !!!!
I hope this helps.
