PTO Solenoid Valve Coil

The PTO solenoid valve coil on the transmission (Fig.
76) can be replaced without opening the hydraulic sys-
tem.
Removal
1. Park machine on a level surface, lower cutting deck,
engage parking brake, stop engine and remove key
from the ignition switch.
2. Raise and support the operator seat to access the
PTO solenoid valve on the transmission.
3. Disconnect the wire harness electrical connector
from the PTO solenoid valve coil connector.
4. Remove the nut from the spool assembly.
5. Slide the coil assembly from the solenoid valve stem
(Fig. 77). For assembly purposes, note that "KANZAKI"
molded into the coil has the "I" nearest the nut location
as coil direction is important for proper solenoid opera-
tion.
6. Clean any corrosion or dirt from the valve stem.
Installation
1. Slide new coil assembly, seals and washers onto the
solenoid valve stem. Make sure to properly position
seals and washers (Fig. 77). Coil should be installed so
the "KANZAKI" molded into the coil has the "I" nearest
the nut location.
IMPORTANT: When securing solenoid valve coil to
solenoid, do not over- -tighten hex nut.
2. Install the hex nut onto the spool assembly and
torque nut from 53 to 69 in- -lb (5.9 to 7.8 N- -m).
3. Connect the wire harness electrical connector to the
solenoid valve coil connector.
4. Lower and secure operator seat.
