TMS700E SERVICE MANUAL
1. Position the air bag(s) on the saddle assembly and
secure each with a bolt and lockwasher.
2. Position the trunnion tube through the center bushing on
each walking beam. Position each saddle assembly
over the center bushing and secure with the pivot block
cap and two bolts and lockwashers. Torque the bolts 305
to 373 Nm (225 to 275 lb-ft).
3. Position the axle(s) under the walking beams aligning
the axle brackets with the bar end bushings on the
walking beams. Secure each end with two bolts,
washers, and nuts. Torque the bolts 610 to 814 Nm (450
to 600 lb-ft).
4. Position the shock absorber(s) on the saddle assembly
and secure each with a nut and two washers. Torque the
nuts 305 to 373 Nm (225 to 275 lb-ft).
5. Position the torque rods in the axle brackets and secure
each with two bolts, hardened washers, and nuts.
Installation
1. Position the axle and suspension assembly under the
carrier.
2. Raise the assembly into position under the carrier
aligning the saddle assemblies pivot blocks and air bags
with the mounting brackets on the carrier.
3. Install the four saddle assemblies' cap blocks and
secure each with the two bolts and washers. Torque the
bolts to 305 to 373 Nm (225 to 275 lb-ft).
4. Secure the four air bags to the carrier brackets with two
nuts and washers. Torque the nuts to 41 Nm (30 lb-ft).
5. Secure each shock absorber to the carrier frame with a
nut, lockwasher, and hardened washer.
6. Secure the linkage rod of each height control valve to its
respective saddle assembly
hardware.
7. Attach each steer cylinder's attached ball socket to the
axle using the ball socket's slotted nut and a cotter pin.
Add hardened flat washers as needed to ensure proper
seating of cotter pin in slotted nut. Torque nut 136 to 170
Nm (100 to 125 lb-ft). Tighten to nearest cotter pin hole
and insert cotter pin. Take care not to damage hydraulic
lines.
8. Attach the vertical socket drag links to each axle using
the slotted nut and cotter pin. Torque nut 136 to 170 Nm

operation.
Place wood blocks between the saddle assemblies and
the frame so that the top surfaces of the saddle
assemblies are parallel to the bottom of the carrier
frame.
Measure the longitudinal distance from the center of the
rear axle saddle blocks to the center of the king pin on
the last front axle (see Figure 8-2). If necessary, adjust
the shims in the walking beam ends. The correct side to
side location is achieved by adding or removing shims at
the lateral rods.
Measure diagonally from the center of the rear axle
saddle blocks to the center of the opposite king pin on
last front axle (see Figure 8-2). If the diagonal
measurements are not within 12.7 mm (0.50 in), check
the location of the suspension hangers and air bag
hangers and adjust as necessary.
Double check all measurements made in steps 1 thru 3
and readjust the shims if necessary.
Repeat steps 2 thru 4 to align the first front axle. Use the
king pin centers of the last front axle for making the
necessary longitudinal
measurements to the first front axle. If the diagonal
distance from one side to the other is not within 6.35 mm
(0.25 in), check the location of the suspension hangers
and air bag hangers and adjust as necessary.
