TMS700E SERVICE MANUAL UNDERCARRIAGE
7. Jack the jack cylinder up just enough to insert the
retaining pin back into the cylinder’s lugs. Insert the
retaining pin into the lugs on the cylinder and secure it in
place with the cotter pins.
8. Fasten a nylon strap onto the cylinder retaining pin and
use an adequate lifting device to lift the jack cylinder out
of the tube.
9. Remove the wear ring from the groove of the cylinder.
Remove the wear ring from the groove in the bottom of
the tube.
Installation
1. Apply grease (EP-MPG) to the ID of the jack cylinder
support tube.
2. Install piston wear ring in groove in bottom of support
tube and install cylinder head wear ring in groove at top
on jack cylinder.
3. Place a jack beneath the cylinder tube. Using the same
method as described under Removal, lower the jack
cylinder into the cylinder tube until the retaining pin is
just above the tube. Position the jack so that it will
support the cylinder in this position. Remove the lifting
device from the cylinder.
4. Remove the retaining pin and cotter pins from the
cylinder.
5. Lower the jack until the holes in the cylinder rod align
with the holes in the tube. Apply grease (EP-MPG) to the
retaining pin. Secure the cylinder and cylinder cap
bracket in place with the retaining pin and cotter pins.
6. Install the hydraulic lines as tagged prior to removal.
7. Secure the cylinder tube cap to the cylinder bracket with
a replacement black nylon washer and the acorn nut.
8. Position the float pad on the cylinder ball and secure
with bolts, bushings, lockwashers, and nuts. Tighten
each nut until the washer contacts the pad and the nut.
Do not tighten either nut onto their related bolts any
further; this allows the pad to pivot.
9. Position the tilt bar on the mounting bracket and secure
with the screws, washers, lockwashers, and nuts.
Functional Check
1. Extend and set the outriggers.
2. Activate the hydraulic system; extend and retract the
outrigger.
3. Observe for proper operation of the center front jack
cylinder.
4. Check the hydraulic connections for evidence of
leakage.
CAUTION
Use a nylon strap to remove the cylinder. This will ensure
the retaining pin is not damaged.
CAUTION
When installing cylinder retaining pin, orient it so that
when cotter pins are installed they will be horizontal.
CAUTION
Extend and set the four main outriggers before extending
the center front jack.
