Installation Instructions

MTU Instruction
for Rockwell/Equimeter/Sensus Gas Meters
Step 4 – Remove and discard the
existing couplers and shaft from the MTU
and assemble the new couplers and shaft
to the MTU, positioning the female
coupler at the back of the MTU and the
12-tooth gear with magnet at the front as
shown below. Ensure that both couplers
are securely snapped on to the coupler
shaft.
Step 5 – Insert the four #10-24 x 1-1/8”
machine screws into the holes at the
corners of the index box as shown.
Step 6 – Turn the MTU over and position
the rubber gasket over the screws and
female coupler as shown. The cork side
of the gasket should face out as shown
below.
Step 7 - Position the MTU on the meter,
sliding the female coupler over the drive
gear on the meter. Tighten the MTU
mounting screws to 12 to 15 in-lb.
Check the coupler. It should have slight
play — it should not bind or turn too
freely.
CAUTION!
Do not over tighten screws.
Excessive torque may
damage the MTU enclosure.
Power tools are not
recommended for use on
steps 8-12.
