Adjustment For Lift Linkage In Tank
Move the control lever to the RAISE position. Approximately 20 lbs. (90 N) force is needed to move the control lever from the RAISE position. If much less force is needed to move the lever from RAISE position, an adjustment is needed.
LIFT LINKAGE
1. Lever and cam. 2. Roller. 3. Pin. 4. Rod assembly. 5. Valve spool (for lift control). 6. Plate. 7. Spring. Y. .29 in. (7.3 mm) measurement.1. Remove the oil from the hydraulic tank.2. Remove the bottom of the hydraulic tank.3. Disconnect spring (7) from plate (6). Connect the spring in a hole in plate (6) which puts more tension on spring (7). If there is no hole in plate (6) to make an increase to the tension of spring (7), install a new spring.4. When the linkage in the tank is being assembled, it is necessary to make an adjustment for the length of rod assembly (4). Connect one end of rod assembly (4) to lever and cam (1).5. With the control lever in RAISE position, the distance between roller (2) and lever and cam (1) is .29 in. (7.3 mm) measurement (Y).6. Make an adjustment for the length of rod assembly (4). When the control lever and valve spool (5) are in the HOLD position, pin (3) must be installed with no movement to valve spool (5). Pin (3) must be installed horizontal with the cover on top of the tank.
