TRACTION LOCK
Removal and Installation
AVOID INJURY OR DEATH
Do not modify the electrical wiring connected
to the traction lock solenoid or any part of the
traction lock system. The traction lock
provides the locking function of the parking
brake. Service work on the traction lock system
should only be performed by a qualified
technician. Use only genuine Melroe parts if
repair is necessary.

Raise the loader operator cab. (See Page 1–1.)
Remove the Do Not Modify sta–strap (P/N 6665527) from
the electric solenoid connector (Item 1) [A].
Installation: Install a new Do Not Modify sta–strap (P/N
6665527) on the electric solenoid connector.
Remove the two mounting bolts (Item 2) [A] from the
electric solenoid mounting bracket.
Installation: Tighten the mounting bolts to 25–28 ft.–lbs.
(34–38 Nm) torque. Be sure the solenoid mounting
bracket is installed in the same position. The solenoid
mounting surface has a slight angle which tips the top of
the solenoid toward the rear of the loader when installed
correctly.
Remove the electric solenoid and bracket assembly from
the chaincase cover [B].
Remove and inspect the compression spring (Item 1) [B]
for wear or damage. Replace if necessary. The spring
may also stay with the shaft when the electric solenoid
and bracket are removed from the chaincase.
Installation: Install the compression spring (Item 1) [B]
on the collar located on the electric solenoid.
Remove the traction lock assembly (Item 1) [C] from the
chaincase.
Remove the shaft mounting bolt (Item 1) [D], washer and
spring from the assembly shaft (Item 2) [D]. Remove the
wedge (Item 3) [D] and inspect all parts for damage or
wear. Replace if necessary.
Installation: Thoroughly clean and dry the shaft
mounting bolt (Item 1) [D], the shaft (Item 2) [D] and
wedge (Item 3) [D]. Use LOCTITE 242 when assembling
these parts to the traction lock assembly.
Failure to use LOCTITE may allow the traction
lock assembly to loosen up which can cause
damage to the traction lock system.
