ADJUSTING SHIMS IN ASSEMBLING WORK EQUIPMENT 3
1. When assembling the work equipment, adjust an amount of play at each part (C) to the right values shown in
the following table.
2. After the assembly, grease shim adjusting positions (1) to (3) and check that each part turns smoothly.
ADJUSTING TENSION OF CENTER BRACE 3
(Power tiltdozer only)
(Powertilt, Power pitch dozer only)
In case the work equipment assembly is disassembled for transportation and reassembled at a worksite, tension
of the center brace has to be adjusted anew. Otherwise the bushing at the connecting part of blade and straight
frame will likely slip off, allowing sand and dirt to enter the bushing, which eventually leads to premature wear or
damage of the bushing. Make this adjustment as follows:
WARNING
Except when operating the blade in Step 4, always lock the blade control lever securely with the work
equipment lock lever.
1. Adjust with shim (2) so that the play of ball joint (1) is 0.2 to
0.5 mm.
2. Loosen bolt (3).
3. Install the blade assembly.
4. Operate the blade control lever to float the blade.
5. Insert bar (4) in the center brace hole and turn the bar to
the protruding side. At that time, adjust clearance between
the track shoe and frame (D) so that it is equal on the right
and left sides.
Rotating torque: 24.5 to 49 N·m (2.5 to 5 kgf·m) (Blade at
FLOAT)
Standard distance between the joints (B) is as shown
below.
D65EX: 995 mm
D65PX: 992 mm
D65WX: 995 mm
6. Tighten bolt (3).
Tightening torque: 490.3 to 608 N·m (50 to 62 kgf·m)
