Lovol TE254 - Tractor Running-in

3.15 Tractor running-in
Before using the tractor, it should run
for a time of period according to specified lubricating, speed and load
conditions. Meanwhile, the tractor should be checked, adjusted and maintained for normalization of its technical
state. Such a series of operations is called running-in.
3.15.1 Preparations for running-in
 During running-
in, carry out each shift and every 50h technical maintenances (see this manual 4
Maintenance Manual)
 Check and tighten all bolts, nuts and screws outside of tractor.
 Add the grease into the oil cup on the front wheel hub, front drive axle kingpin and water pump shaft.
Check the oil level in the engine oil sump, drive system, lifter, main drive of front drive axle and final drive,
fill it if necessary.
 Fill up the fuel and coolant met required grade.
 Check whether the tire pressure is normal.
 Ensure all electrical element circuits are correct and reliable.
 Place each handle at neutral.
3.15.2 Engine idling running-in
Carry out engine running-in with no load for 15min.Start the engine according to order descried in “Diesel Engine
Use and Maintenance Manual”: from the low speed (small throttle) to middle speed (medium throttle) then to high
speed (full throttle). Run it for 5min in turn.
During the engine idle running-in, please carefully check the engine, air compressor, hydraulic pump for normal
operation. If abnormal, please check if there is leakage of air, water and oil. Check the instrument for normal. In
case of abnormal, please stop immediately, troubleshoot and then run-in again.
You can start the following running-in only the engine is normally working.
3.15.3 PTO running-in with no load
Place the engine accelerator control handle to medium throttle to keep the engine rotate at medium speed. PTO
respectively works at the low speed and high speed for 5min to check if there is abnormal phenomenon. After
running-in, the PTO should be placed at the neutral position.
3.15.4 Hydraulic system running-in
Start engine, place the throttle to medium position and control the distributor handle to lift or lower linkage for a
few times. Check whether any component is normal or not.
Then mount 300kg substance or equivalent
agricultural implement to the linkage and allow the engine running at full throttle. Control the distributor handle to
make the linkage lift or lower to full travel for 20 times or more.
Check whether the hydraulic hitch system is
fixed at max. height or desired position, needed time for lifting or lowering and any leakage.
With tractor at the same place, let the engine run respectively at the low, medium and high speed, whilst turn the
steering wheel to the left and the right respectively 10 times. Then observe the servo of front wheel steering to the
left and right. Inspect the sound for normal and whether steering wheel turning is easy and steady.
If any failures occur during running-in, please troubleshoot.
3.15.5 Tractor idling and running-in with load
As to the idle running-in, after the running-in of PTO and hydraulic hitch system, make sure the technical state of
tractor is completely normal and then carry out the entire tractor running-in according to table 3-2. During no-load
running-in, properly apply the single-side brake in turning
with a low speed and test emergency brake application
when running with a high speed.
After idle running-in, be sure the tractor technical state is normal and then carry out running-in with load. The
load should be increased from lower value to higher value. The gear should be shifted from the low speed to high
