24. SERVICE PROCEDURE 24.2.9 ADJUST BUCKET CLEARANCE 1. Set the work equipment to the position shown in the diagram at right, stop the engine and set the safety lock lever to the lock position. 2. Shift O-ring of the linkage and measure the amount of play (a). Measurement is easier if you move the bucket to one side or the other so all the play can be measured in one place. (In the diagram this is on the left-hand side) Use a gap (clearance) gauge for easy and accurate measurement. 3. Loosen the four plate fixing bolts of and loosen plate . Because it uses split shims, you can carry out the operation without removing the bolts entirely. 4.

Remove shim corresponding to the amount of play (a) measured above. (Example) If the play is 3mm, remove the two sets of 1.0mm shim (4 pieces) and 0.5mm (2 pieces) and the play will become 0.5mm. Four sets of 1.0mm (8 pieces), two sets of 0.5mm (4 pieces) are installed. Two pieces of shim makes one set. When play (a) is smaller than one shim, do not carry out any mainte- nance. 5. Tighten the four bolts . If the bolts are too stiff to tighten, pull out pin stopper bolt for easier tightening.
