Doosan Forklift D25S-9

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.

Check to make sure the tilt cylinders extend and retract evenly

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

To adjust the cylinder rod extension, move the spacer to the rear and loosen the pinch bolt on the clevis

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

Tighten the pinch bolts to a torque of 95±15 Name (70 ± 10 abaft)

Check the cylinder rods again for even travel
