TMS800E SERVICE MANUAL
7. Partially extend the outrigger beams. Attach a string line
to front and rear outrigger beams as shown in
Figure 8-2. Ensure the string line is taut and level.
8. Refer to Figure 8-2 and ensure that Dimension C equals
Dimension D and that Dimension E equals Dimension F.
9. Refer to Figure 8-8 and adjust the drag links (Detail 5) as
required so that the distance from the string line to the
front of each wheel is the same as the distance from the
string line to the rear of the same wheel within 1.5 mm
(0.06 in). Check that the rod ends of the drag links are
within limits specified in figure.
10. Remove the rig pins.
Setting Axle Stops and Steering Gear Relief Plungers
1. Start the engine and run at idle.
2. With the wheels on greased plates, turn the wheels in
both directions and check for clearances between all
moving parts. The clearances should be between
25 mm (1.00 in) and 38 mm (1.50 in).
3. Adjust the axle stop as necessary to get the maximum
cramp angle and proper clearances.
4. Put the full weight of the machine on properly inflated
tires and on a hard firm surface.
5. Remove cap from test nipple at port GP8 upstream from
the inlet of the power steering gearbox. Install a
pressure check diagnostic quick disconnect with gauge
onto test nipple at port GP8.
CAUTION
To prevent pump damage/failure due to heat build up, run
the engine in this configuration for a maximum of 30
seconds to 1 minute.
6. Start engine. Slowly drive the crane forward and turn the
wheels to full left turn and against the axle stop. Verify
solid contact against axle stop; screw in the power
steering gearbox's front plunger to decrease travel or
screw it out to increase travel as needed. Check

pressure; it should not exceed 62 bar (900 psi).
(Figure 8-9)
7. If the pressure is too high or the axle stop is not making
contact with the axle, adjust the front plunger so the axle
stop makes contact with the axle and the pressure
reading does not exceed 62 bar (900 psi). Screw the
front plunger in to decrease travel or screw it out to
increase travel so pressure reading does not exceed 62
bar (900 psi).
NOTE: Do not attempt to set the relief pressure with the
tires off the ground.
8. Slowly drive the crane forward and turn the wheels to full
right turn and against the axle stop. Verify solid contact
against axle stop; screw in the power steering gearbox's
rear plunger to decrease travel or screw it out to
increase travel as needed. Check pressure; it should not
exceed 62 bar (900 psi).
9. If the pressure is too high or the axle stop is not making
contact with the axle, adjust the rear plunger so the axle
stop makes contact with the axle and the pressure
reading does not exceed 62 bar (900 psi). Screw in the
rear plunger to decrease travel or screw it out to
increase travel so pressure reading does not exceed 62
bar (900 psi).
NOTE: Do not attempt to set the relief pressure with the
tires off the ground.
10. Stop engine. Verify both plungers are screwed into the
gearbox far enough so the head of each plunger is at
least 4 mm (0.16 in) below the top of its threaded hole. A
plunger screwed in less deeply than this could cause or
suffer damage. Remove diagnostic gear and reinstall
cap on port GP8.
11. Ensure the top surface of each saddle assembly is
parallel with the bottom surface of the carrier frame by
measuring the distance at the front and rear of the
saddle assemblies. If necessary, adjust the height
control valves to raise or lower the saddle assemblies
into a parallel position.
