5. MAINTENANCE AND INSPECTION
1. BODY
DRIVE WHEELS
Pay constant caution to see that the set bolts of the power axle are not loosened.
Make sure that the wheel tightening nuts are not loosened.
When tightenting the nuts, be sure to tighten the nuts located at diagonal position scquentially so
that they should not be tightened in deviant way.
Make sure that there is no oil leakage from the drive gear case.
Also, check that the tightening bolts are not loosened.
REAR WHEELS
Be sure to pay caution constantly so that the wheel tightening bolts are not loosened as in the
case with the drive wheels.
When reassembling the idle wheels after disassembling them for alignment, be sure to
reassemble them just in the reverse of disassembling.
STEERING SYSTEM
Since the steering system is particularly an essential part, be sure to check each part of the
system for alignment, damage, deformation, etc., so that it can be always kept under the optimum
condition.
BRAKE
Check the brake pedal for "play" and pedalling allowance when it is stepped on, and looseness of
each part, etc.
If the tractor slides laterally when the brake is applied suddenly, the brake is applied unevenly.
In this case, adjust the brake so that it can be applied evenly.
Check and adjust the gap between the parking brake lining and the drum, and the braking
efficiency.
Parking brake
Adjust the parking brake to such an extent that there still remains some pulling allowance when
the brake lever is fully pulled. Make sure that the brake is held in a condition not to be applied at
all when the lever is returned.
