REPLACING V7058 WITH MCV104 FOR S20 PV
Replacing the V7058A1296 hydrotransmission valve with the
MCV104 EDC valve is acceptable and often recommended. The
MCV104xxxxx can be mounted directly in place of the V7058
without changing the pump drag link. The EDC operates with
lower electrical current and voltage, therefore a 50 to 75 ohm 3
Watt resistor must be placed in series to the EDC. The current/
voltage used for the V7058 will be reduced from approximately
250 mA at 9.0 Volts to 130 mA at 2.6 Volts for dual coil EDC, and
90 mA at 2.3 Volts for single coil EDCs. If a single coil EDC is used,
select a 75 ohm 3 Watt resistor. When using a dual coil EDC, select
a 50 ohm 3 Watt resistor.
The electrical connection is accomplished through two wires with
the V7058 or EDC. The EDC can be either a single coil (coil A/B)
or dual coil (coils A/B and C/D). If a dual coil EDC is used only the
A and B pin connections are required for operation.
-
fying the switching function for FWD and REV of the pump if just
a potentiometer is used, i.e., A/B coil for FWD and C/D for REV.
