5.4.2.9 Operation 24.
Lubricate pivot axis bearing of FDA
Note – The operation is performed on tractors with FDA with planetary cylindrical wheel
hub drives (822-2300020-02/04, basic configuration).
To oil pivot axis bearing 3 perform the following:
- remove the caps 1 (Figure 5.4.13) from four lubricating boxes 2 and bearings 3;
- clean lubricating boxes 2 from accumulated dirt and consolidated lubricant;
- squirt lubricating boxes 2 with lubricant, performing six injections.
1 – cap, 2 – lubricating boxes; 3 – bearing.

5.4.2.10 Operation 25.
Check/adjust air conditioner compressor drive belt tension
Note – Operation shall be carried out when the tractor is equipped with air condi-
tioner instead of fan-heater.
1. Check of air conditioner compressor drive belt tension:
Belt 1 tension (Figure 5.4.14) of air conditioner compressor drive is considered to be
normal if bending deflection of its side “engine crankshaft pulley – compressor pulley” meas-
ured in the middle range within 4 to 6 mm with force of (39.2
±
2.0) N applied.
In case the condition is not observed it is necessary to adjust air conditioner compres-
sor drive belt tension.
2. Adjustment of air conditioner compressor drive belt tension:
Adjustment of belt 1 tension (Figure 5.4.14) shall be carried out by turning compressor
2 on rotational axis
А
and threaded joint clamp B in slot C. Belt bending deflection in re-
sponse to force of (39.2+2.0) N applied to the center of belt side must range within 4 to 6 mm.
1 – belt; 2 – compressor.
