Possible Failures Of Fda And Guidelines For Troubleshooting - Belarus 1822.3 Operator's Manual

Oil pressure loss in transmission hydraulic system
Breakdown of gear wheel pump in
transmission hydraulic system
Transmission hydraulic
pump actuator
Damaged parts of transmission hy-
draulic system pump actuator
High oil pressure in transmission hydraulic system
Oil does not corresponds to the
current season (ambient tempera-
ture)
Deadlock of distributor-filter by-
pass valve
Insufficient oil level in transmission
Wear or breaking of bearings of
other transmission components

7.11 Possible failures of FDA and guidelines for troubleshooting

List of possible failures of front driving axle and guidelines for troubleshooting are
shown in Table 7.11.
Table 7.11
Failure,
external manifestations, cause
Faulty toe-in
Noncompliance of pressure in tires
to the recommended standards
Pressure loss in clutch booster
Failure of system electrics
Low pressure in transmission hy-
draulic system
Increased leakage in drive control
hydraulic system:
- wear of O-rings of piston and
drum;
- wear of mating surfaces sleeve –
drum hub, drum – piston;
Replace gear wheel pump of transmission hydraulic
system
system Engage transmission hydraulic system pump ac-
tuator
Replace damaged parts of transmission hydraulic
system pump actuator
Fill in corresponding seasonal oil
Rinse distributor-filter bypass valve
Increased noise
Check oil level in transmission as indicated in sec-
tion 6 "Maintenance service". Refill oil up to the re-
quired level if necessary.
Replace bearings
increased wear and delaminating of front tires
Adjust toe-in as indicated in section 6 "Maintenance
service".
Adjust pressure in tires as indicated in subsection
4.2.8 "Choice of optimal inflation pressure of tire
depending on operating conditions and tractor axle
load, and tires operating rules"
Drive clutch does not transmit torque
Disassemble distribution valve, rinse case and
spool
Detect and correct trouble in ECS of FDA
Insufficient value of torque transferred
Adjust pressure in transmission hydraulic system
up to the value 0.9 to 1.0 MPa
Replace O-rings
Replace worn-out parts
