C.Important Safety process and critical functional process
The following instructions are related to essential adhesives, important safety process and critical func-
tional process .Pay special attention in servicing these process. (Pay also close attention in reconnecting
the electrical cables.)
a. Essential Adhesives
Type of screw adhesive
• Unless otherwise specified, use Three-Bond 1324 adhesive (medium-duty type).
Keep the screw threads free of oil and water.
Type of instantaneous adhesive
• Use Three-Bond 1733 or Three-Bond 1741E adhesive.
Keep the bond areas free of oil and water.
b. Important Safety Process
.
1. Reconnecting the fuel hose (clearance, hose routes, clamps, etc.)
2. Electrical cabling (engine, instrument panal, controls, etc.) (wiring routes, clamps and couplers)
c. Important Critical Functional Process
.
1. Setting up the travel wheel motor (tightening torque)
2. Reassembling the rotary joints (joint direction and shaft set-up)
3. Installing the swivel base bearing and the swivel motor (tightening torque)
4. Fitting the pump couplings (tightening torque)
D.Important inspection items after reassembling
a. Operate the Machine and check for Unusual Noise and Vibrations.
b. Make Sure the Safety decals and Wireharness Clamps are in their
Specified Positions.
c. With the Machine Front in a Specified Posture, Check the Amount of
Hydrauric Oil
Checking the oil level (For further datails, refer to the Operator’s Manual of each model.)
1) Park the machine on a level ground.
2) Make sure the hydrauric oil temperature is in the range of 10-30°C (50-86°F) and see if the oil level is
within the specified zone of the oil level gauge.
3) Extend the track cyrinder to Max. position.
4) Keep the machine front as shown as following posture.
Posture: Extend the rods of the arm and bucket cylinders to max. Place the bucket link on the ground, the
offset swing at the center, and the dozer also on the ground.
