Dozer Run-in
10 Minutes Run-in of the Engine at Idle Speed
Start up the engine and increase the engine speed to raise coolant temperature and the engine oil pressure.
Check if there is any oil or water leaking. Pay attention to the sound of the engine running and notice the
indication of the ammeter, water thermometer, and the oil pressure gauge. Continue the next run-in
procedure only after this 10 min run-in.
10 Minutes Run-in of Hydraulic Hitch System
After an implement has been mounted, the hitch is raised and lowered smoothly for more than 10 min, when
the engine is running at rated speed in order to keep run-in smooth, the implement cannot be raised or
lowered on the hard ground.
Two-hour Run-in Without Load
The dozer should be in run-in according to normal use and the operator should do the following.
Shifts F-low 1 F-low 2 F-low 3 f-high 1 R 1
Time (min)
20 30 30 30 10
In this run-in, the operation of both sides of the steering system and the brake should be carried out. It
’ s
necessary to pay attention to the following items.
•
Listen to the engine and transmission.
•
Check whether the clutch, brake, and gearshift levers are normal.
•
Check whether the gauges and electrical system work normally.
If abnormal occurs during the run-in, address it before continuing the run-in process.
48-hour Run-in Under Load Conditions
‘Run-in with load’ means that it’s necessary to run the dozer with different loads. The load should be
increased gradually from light to heavy while increasing the speed from low to high.
Measures After Run-in
After the run-in, if any impurities are found in the engine oil sump, gearbox, or hydraulic system, it must be
removed. Also, replace all lubricants and the hydraulic oil. After the essential maintenance, the dozer can be
put into normal use The maintenance steps are as follows:
•
Drain out the engine
oil when it’s hot, just after the engine is shut off. Then clean the sump with clean
diesel fuel and replace the engine oil filter element. Lastly, refill the engine oil.
•
Drain out the oil from the gearbox and final drive cases when
it’s hot, just after the engine is shut off.
Then, refill with clean diesel fuel and run the dozer for 3-5 minutes at lowest speed. Drain diesel and fill
with the appropriate amount of clean oil.
•
Replace the fuel filter element.
•
Drain out the oil from the hydraulic system and refill with the appropriate amount of clean hydraulic oil.
•
Replace
engine’s coolant.
•
Fill grease into the lubricating points in accordance with indication of lubricating drawing.
•
Check the tension of the tracks. If the sag exceeds 2.5mm (1in.), adjust.
•
Inspect the brake and
steering pedals’ free strokes, adjust if necessary.
•
Inspect all fasteners and retighten any loose connections.
