PROCEDURE FOR ADJUSTING SHIM WHEN ASSEMBLING WORK EQUIP-
MENT
1. When assembling the work equipment, adjust the play at
all parts to the correct value.
2. After assembling, grease adjustment portions (1) to (3) and check that they rotate smoothly.
ADJUSTING TENSION OF CENTER BRACE
(Power tiltdozer only)
(Powertilt, Power pitch dozer only)
When the blade assembly is removed for transportation, the tension of the center brace must be adjusted when
the blade is assembled again. If the tension is not adjusted, the bushing at the blade and straight frame mount will
come out, and soil will enter. This will result in damage or premature wear of the bushing.
WARNING
Except when operating the blade in Step 4, always lock the blade control lever securely with the safety
lock lever.
1. Adjust with shim (2) so that the play of ball joint (1) is 0.2
to 0.5mm (0.008 to 0.020in).
2. Loosen bolt (3).
3. Install the blade assembly.
4. Operate the blade control lever to float the blade.
5. Insert a bar in hole (4) in the center brace, and turn it in
the direction of protrusion. When doing this, adjust so
that clearance D between the track and frame is the
same on the left and right sides.
Rotating torque: 24.5 to 49N•m (2.5 to 5kgf•m, 18.1 to
36.2 lbft). (Blade at FLOAT)
Standard distance ( l ) between joints is shown below.
D65EX: 995 mm (39.2 in)
D65PX: 992 mm (39.1 in)
6. Tighten bolt (3).
Tightening torque: 490.3 to 608N•m (50 to 62kgf•m,
361.7 to 448.4 lbft.)
