Mast Pivot Eyes-Lubricate
Typical Example
1. Lubricate two fittings for the mast pivot eyes,
one on each side of the pin.
2. Check the pivot eye pins for loose retainer bolts
and wear.
Cylinder Rod Extension-Adjust
NOTE: The following description is for forward tilt.
For cylinder rod back tilt, the collar should
be stationary by the tilt eye. If it is not, the
O-ring inside the collar may need to be
replaced. To adjust back tilt, spacers must
be added or removed.
Typical Example
1. Check to make sure the tilt cylinders extend
and retract evenly.
2. If one cylinder continues to move after the other
cylinder has stopped in full forward or backward
tilt, an adjustment must be made to one
cylinder.
Typical Example
3. To adjust the cylinder rod extension, move the
spacer to the rear and loosen the pinch bolt on
the clevis.
4. Turn the cylinder rod in or out of the clevis to
obtain the proper adjustment. Turning the rod
into the clevis shortens the stroke. Turning the
rod out of the clevis lengthens the stroke.
5. Tighten the pinch bolts to a torque of 95±15
Name (70 ± 10 abaft). Check the cylinder rods
again for even travel.
Crosshead Rollers - Inspect
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.
