25. With barrel clamped securely, and while adequately
supporting the rod, insert the piston end into the
barrel cylinder. Ensure that the piston loading o-ring
and seal ring are not damaged or dislodged.
26. Continue pushing the rod into the barrel until the cyl-
inder head gland can be inserted into the barrel cyl-
inder.
27. If applicable, secure the cylinder head retainer using
a suitable chain wrench.
28. After the cylinder has been reassembled, the rod
should be pushed all the way in (fully retracted) prior
to the reinstallation of any holding valve or valves.
29. If applicable, install the cartridge-type holding valve
and fittings in the port block using new o-rings as
applicable. Refer to Figure 4-13., 1932RS/6RS - Lift
Cylinder on page 4-13. or Figure 4-14., 3248RS/
10RS - Lift Cylinder on page 4-14
Lift Cylinder - LSS Pressure Sensor Location
(If Equipped)
Lift cylinders on machines with the Load Sensing System
(LSS) are equipped with two pressure sensing transduc-
ers installed. These sensors, two are used in case one
should fail, are wired in parallel directly to the machine
control module as part of the LSS system.
