MAINTENANCE PROCEDURE MAINTENANCE ADJUST BUCKET CLEARANCE 4 It is dangerous if the work equipment is mistakenly moved when adjusting the bucket clearance. Set the work equipment in a stable condition, stop the engine, then set safety lock lever (1) securely to the LOCK position (L). 1. Set the work equipment to the position shown in the dia- gram on the right, then stop the engine and set the lock lever to the LOCK position. 2. Shift O-ring (1) of the linkage and measure the amount of play “a“. Measurement is easier of 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 mea- surement. 3. Loosen 4 plate mounting bolts (2) and loosen plate (3). 4. Remove shim (4) corresponding to the amount of play “a“ measured above. [Example] In the case of play of 3 mm, remove two 1.0 mm shims and one 0.5 mm shim. Play becomes 0.5 mm. For shim (4), two types of 1.0 mm and 0.5 mm are used. When play “a“ is smaller than one shim, do not carry out any maintenance. 5. Tighten the four bolts (2). If the bolts (2) are too stiff to tighten, pull out pin stopper bolt (5) for easier tightening. (6): Arm (7): Bucket 4-36 WARNING
