Note: That both transfer caps only mount in one orientation. Prior to installation of cap assembly be sure to
check that the stainless steel spring and the plastic spring support is in place attached to the inside of the c
assembly. Next you can wipe the outside edge of the O-ring on the cap and the inside mating area of the valve
with a clean cloth & re-apply a thin layer of silicone lubricant like Dow #7.
BE SURE NOT TO USE ANYTHING HYDROCARBON BASED SUCH AS VASELINE OR
PETROLEUM JELLY TO LUBRICATE PLASTIC COMPONENTS OR O-RINGS AS THEY WILL
BE DAMAGED BY THE HYDROCARBONS AND POTENTIALLY CAUSE FAILURES THAT CAN
RESULT WITH LEAKS.
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 hand to start two screws in, one
on the top and one opposing it on the bottom. Tighten the
screws in evenly so 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 careful 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 white drive gear with the “A” pointing
toward the 1 o’clock position and then press it onto the
stainless steel drive shaft, make sure it snaps & 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
fi
t on the shaft.
Next install the larger black reducing gear onto the stainless steel shaft, then install the remaining smaller
reducing gears from left to right. Re-install the grey reducing gear cover over the gears and af
fi
x with the 3
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 untill 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
fl
ush with the top of the
grey gear housing. Press the drive motor wires down into the strain relief of the drive cap, now you can
re-install the cover assembly.
After completing any valve maintenance involving the valve drive assembly or the transfer drive
assembly please press and hold the NEXT & the REGEN buttons simultaneously for 3 to 5 seconds to
perform a soft reset which will synchronize the control valves positions.
