If this does not occur, a linkage adjustment may be necessary. An electrical failure in the transmission neutralizer or the electrical wires could also be the cause.The pulled unit hoist control (1) must be 365 mm (14.4 inch) from the floor of the cab when the pulled unit hoist control is in the HOLD position. If the measurement for dimension (2) is not correct, the control linkage needs to be adjusted.Control Linkage Operation
The pulled unit hoist control (1) is located to the left of the operator's seat. This pulled unit hoist control is connected to a cross shaft (3) which exits the cab on the right side of the cab. Lever (4) connects cross shaft (3) to end (7) of the adjustable rod (5). End (10) is part of rod (5). End (10) is adjustable. End (10) connects to a lever (11). Lever (11) is connected to cross shaft (6) which is connected to another lever. This part of the control linkage is enclosed in a cover assembly. A cable assembly (18) with an adjustable end (13) connects to the cross shaft on one end and to lever (16) at the hydraulic tank on the other end.Control Linkage Adjustment
Hold the actuating lever (16) perpendicular to rod end (15) during the following adjustments. This is the HOLD position.
Adjust rod end (15) of cable assembly (18) in order to get a distance of 197 mm (7.8 inch) (17) .
Tighten locknut (14) .
Make the necessary adjustments at locations (7), (10), or (13) in order to get a distance (2) of 365 mm (14.4 inch). This is the correct distance between the pulled unit hoist control (1) in the HOLD position and the floor of the cab.
Tighten all respective locknuts (8), (9), or (12) .
Make sure that it is possible to position the pulled unit hoist control (1) and lever (16) in all four positions of operation.
