Inspection & Adjustment
2-7. F-R lever linkage adjustment
★ When the F-R lever linkage has been
renewed (or reconnected) or if the F-R
lever fails to move smoothly, adjust as
described below:
1. Adjustment
★ Hydraulic oil temperature: 50±50°C
(122±41°F)
★
Adjust the length of linkage between the F-
R lever and pump control lever so that the
pump control lever secures the correct
neutral position with the F-R lever held in
the neutral position. (F-R lever (1) is posi-
tively detent-positioned in the neutral, for-
ward travel and reverse travel positions.)
1) Set the F-R lever to the correct neutral
position. Adjust the length of rod (2) and
cable (3) as shown.
• Length:
Rod (2)
➡
290 mm (11.41 in.)
Cable (3)
➡
401 mm (9.37 in.)
★ Make sure that the F-R lever moves
smoothly.
2) Set pump control lever (4) to the neutral
position. Connect the cable to the pump
control lever with length ‘a’ adjusted by
nuts (5).
3) Move the F-R lever to notch positions (for-
ward and backward) to see if lever(4) cer-
tainly follows the F-R lever movement.
4) To adjust the neutral position, rotate nuts
(5), while moving the F-R lever (neutral
➡
forward
➡
neutral
➡
backward
➡
neutral),
so that the F-R lever travel from the neutral
position to the position in which the
machine starts traveling is equal for both
forward and backward traveling.
★ Perform this adjustment on level and
flat concrete pavement while varying
the engine revolution in several steps
ranging from low to high idles.
