Servicing the Transfer Cap Assemblies
Noting the one possible orientation of the transfer drive cap, use one hand to press in
and support the transfer drive cap while using the opposing had to start two screws in,
one on the top and one opposing on the bottom. Tighten the screws in evenly so that
the cap seats the O-ring without getting pinched or damaged. Screws should only be
hand tightened with a 5/32” or 4mm allen wrench, DO NOT OVER TIGHTEN SCREWS!
Note: Be care and make sure the meter cable doesn’t get under the drive cap while
tightening, as it will result in damaging the cable.
Position the large with drive gear “A” pointing toward the 1 o’ clock position and then
press it onto the stainless steel drive shaft, make sure it snaps and locks into position.
Note: The white drive gear is splined to the drive shaft and will only assemble in one
orientation. Because of this it is not necessary that the discs and gear be exactly
positioned, the positioning needs to be approximate but they have to fit on the shaft.
Next install the larger black reducing gear onto the stainless steel shaft, and then install
the remaining smaller reducing gears from left to right. Reinstall the gray reducing gear
cover over the gears and affix with the three stainless steel screws. Now you can re-
install the drive motor by pressing the spring clip loop to the right then rotate the motor
as you are inserting it so the gear of the motor meshes properly with the reducing
gears. Release the spring clip loop and rotate the motor until the motor housing
engages with the plastic nub inside the housing that holds the motor in place and make
sure that the top of the motor is flush with the top of the gray gear housing. Press the
drive wire motors into the strain relief of the drive cap, now you can reinstall the cover
assembly.
After completing any valve maintenance involving the valve drive assembly or the
transfer drive assembly please press and hold the NEXT and the REGEN button
simultaneously for three to five seconds to perform a soft reset which will
synchronize the control valves position.
