Cylinder Rod Extension - Adjust
1. Tilt the mast to the full forward position.
2. Measure the extended length of the cylinder
rods from the cylinder housing to the pivot eye.
The cylinder rods must be within 3.18 mm (.125
inch) of each other.
3. To adjust the cylinder rod extension, loosen bolt.
4. Turn the cylinder rod in or out of pivot eye to
obtain the proper adjustment. Turning the rod
into pivot eye shortens the stroke. Turning the
rod out of pivot eye lengthens the stroke.
5. Tighten bolt to a torque of 95±15 N·m (70±10
lb·ft). Check the cylinder rods again for even
travel.
6. With the mast at the tilt back position, install
shims as required to permit no gap between
pivot eye and spacer, so the mast does not
twist at full tilt back position.
Crosshead Rollers - Check
Check Operation
1. Operate the mast through a lift cycle. Watch the
chains move over the crosshead rollers. Make
sure the chain is tracking over the rollers
properly.
Typical example
2. Check for damaged crosshead rollers, guards
and retainer rings.
