Tilt Cylinder Alignment
If the tilt cylinders are out of alignment, extra
stresses in the mast assembly and the mast hinge
area will result. To prevent damage, the tilt cylinders
must stop evenly at the end of the tilt back and tilt
forward strokes.
Tilt Angle Check
Tilt Angle Check (Typical Example)
The tilt angle of the mast must be checked in the full
tilt back and full tilt forward positions. Atilt indicator
or a protractor can be used to measure the angle.
Both sides of the mast must be checked to make
sure that the mast is not twisted.
The tilt angle is determined by the tilt cylinders used.
See tilt cylinders in specifications to determine the
tilt angle from the cylinder being used.
Tilt Cylinder Length Check
Tilt Cylinder Length Check
1. Tilt the mast to full forward position. Measure the
extended length of the cylinder rods from the
cylinder housing to the mast. The difference of
length between the two cylinder rods must be
within 3.18 mm (.125 in) of each other.

Tilt Cylinder Adjustment
(1) Pivot eye. (2) Bolt. (3) Rod. (4) Shims. (5) Spacer. (6) Head.
1. With the mast at full forward tilt, loosen bolt (2).
2. Slide spacer (5) back so rod (3) can be turned
into or out of pivot eye (1) to obtain the correct
length or angle.
