How to Set Up the Directional
Valve Linkage
Note: Perform this procedure on a firm, level
surface.
1 Lower the boom to the stowed position.
2 Use a "bubble type" level to be sure the surface
the machine is on is completely level.
Tip-over hazard. Failure to
perform this procedure on a firm,
level surface will compromise the
stability of the machine and could
result in the machine tipping over.
3 Check the tire pressure in all four tires and add
air if needed to meet specification.
4 Remove the drive chassis cover from the
non-steer end of the machine.
5 Disconnect the linkage clevis yoke from the
axle.
6 Place a "bubble type" level on the turntable
rotate bearing plate at the non-steer end.
Confirm whether the drive chassis is completely
level.
7 If the drive chassis is not level, start the engine
and push up or pull down on the linkage
adjustment rod until the machine is completely
level.
Part No. 122985
8 Verify that the ground and drive chassis are
completely level.
9 Loosen the jamb nuts and adjust the length of
the rod by turning the clevis yoke until the
clevis yoke can be pinned to the axle.
10 Install the cotter pin and tighten the jamb nuts.
11 Measure the gap between the drive chassis and
the non-steer axle on both sides (from the inside
of the drive chassis).
Result: The measurements should be equal.
Note: The gap on both sides should be between
0.150 inch / 0.381 cm and 0.170 inch / 0.432 cm.
12 Add or remove shims between the oscillation
stop bar and the drive chassis to achieve the
proper gap.
