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

dicating lamp does not light up,
unit does not operate or FPTO
can be engaged only for a very
short period
Pressure loss in FPTO control
channel
Front PTO does not transmit required power, FPTO shaft end extension is ro-
Operation at lower pressure in
transmission hydraulic system,
skidding of FPTO band-brake
Control cylinder rod is moving
but FPTO does not transmit full
torque or after FPTO shaft dis-
engagement PTO shaft end ex-
tension is still rotating. Cylinder
rod overstroke
FPTO does not transmit full torque or after FPTO shaft disengagement
PTO shaft end extension is still rotating
If clearance spaces in bend-
brakes are adjusted, then it
gives evidence of significant
wear of bend-brakes
Reducing gear parts breakdown Dismount reducing gear from tractor, replace bearings

7.8 Possible failures of brakes and guidelines for troubleshooting

List of possible brakes failures and guidelines for troubleshooting are shown in Ta-
ble 7.8.

FPTO control valve spool jamming is possible.
Check control valve operability by pressing the
rubber cap of electromagnet. After pressing the
cap cylinder rod must be shifted. If cylinder spool
does not move replace the control valve. If the
control valve spool moves and cylinder rod re-
mains fixed then check tractor transmission hy-
draulic fluid pressure. Working pressure should
be within 0.9 to 1.2 MPa. In case pressure is be-
low the required value eliminate transmission hy-
draulic system failure as provided by subsection
7.10 "Possible failures of transmission hydraulic
system and guidelines for troubleshooting"
tating
Operation with FPTO at lower pressure in
transmission hydraulic system is excluded.
Eliminate transmission hydraulic system failure as
provided by subsection 7.10 "Possible failures of
transmission hydraulic system and guidelines for
troubleshooting"
Adjust clearance spaces in bend-brake
Replace bends of PTO shaft
