Carriage or Reach Assembly Adjustments
4500 SRM 971
ADJUST REACH CYLINDERS
NOTE:
The reach cylinders must be adjusted if either
reach cylinder has been replaced or the rod ends have
been removed. Adjustment is also necessary if major
parts of the reach mechanism have been replaced.
The reach mechanism must be adjusted so the outer
frame or sideshifter assembly just touches the stops
on the inner frame with the cylinders fully retracted.
The mechanism must also extend the correct dis-
tance.
WARNING
The points between the scissor arms and the
inner frame/outer frame are pinch points and
can cause an injury. DO NOT put any part of
your body between these assemblies if they can
move. Always move the key to the OFF position
and disconnect the battery.
1.
Cycle the reach system several times to remove
air from the system. Operate the reach mecha-
nism to fully extend and retract the forks for sev-
eral cycles to check for proper operation.
2.
Fully extend the forks, move the key to the OFF
position, and disconnect the battery. Measure
the distance between the contact surface of the
inner frame and the stops on the outer frame.
Measure the distance on both sides. The correct
distance for a single-reach unit is 610 +3
6 mm
(24 +0.12
0.24 in.). The correct distance for a
double-reach unit is 1067 +3
6 mm (42 +0.12
0.24 in.).
3.
If the distance is not within specifications on both
sides, loosen the capscrews at the rod ends of the
reach cylinders. Use a wrench on the wrench
flats to rotate the cylinder rods for adjustment.
Temporarily tighten the capscrews.
4.
Operate the reach mechanism through several
cycles and fully extend the forks. Move the key
to the OFF position and disconnect the battery.
Measure the distance on each side again. Both
measurements must be within specifications
AND the measurements must be within 3 mm
(0.12 in.) of each other. If the measurements
are not within specifications, repeat Step 3 and
Step 4 until all measurements are correct. Tem-
porarily tighten the capscrews without moving
the rods after all measurements are correct.
5.
Fully retract the forks and check each stop on the
outer frame. The inner frame must be touching
the stop pads.
6.
Extend the reach mechanism, move the key to
the OFF position, and disconnect the battery.
Add or remove shims under each stop pad as nec-
essary. DO NOT use more than 3/8-in. shims.
Repeat Step 5 and Step 6 until the outer frame
touches on both sides.
7.
Fully extend the forks, move the key to the OFF
position, and disconnect the battery. Loosen the
capscrews at the rod ends of the reach cylinders.
Use a wrench to rotate the cylinder rods 1/4 turn
clockwise into the cylinder. This adjustment al-
lows the stop pads to absorb the shock instead of
the reach cylinders as the mechanism retracts.
Tighten the rod end capscrews to 35 to 40 N•m
(26 to 30 lbf ft).
