Oil Tank; Drive Of Hll Pump And Transmission Hydraulic System Pump - Belarus 3522.5 Operator's Manual

3.16.2 Oil tank

The tractor is mount with integrated oil tank of LL and HSC systems with a capacity of 100±0,5 l ,
this tank is equipped with breather 1 (figure 3.16.6) with changeable paper element. On front wall of oil
tank are made two joints for free-flow pump drain and for EHR-5LS drain of FLL control. By intaking is
placed intake filter 5 with mesh of 200 micron, this filter should be washed by oil change.
Draining from distributor is made through filler cap 2 of oil tank filter. On front wall of oil tank is
situated emergency oil level/temperature sensor 6 that is actuated at oil temperature increase above
90°С or at oil level fall lower than permissible level.
Oil tank has also two drain holes, which guarantee full drain of waste oil during its sched-
uled change.
1 – breather; 2 – filter cap cover; 3 – filtering element; 4 – filter casing; 5 – intake filter; 6 – oil
level/temperature sensor; 7 – drain from cooling radiator .

3.16.3 Drive of HLL pump and transmission hydraulic system pump.

On drive, which is shown in figure 3.16.7, are mounted together pumps of two hydraulic
systems – of hydraulic lift linkage and transmission hydraulic system. Rotation is transmitted by
cone gear shaft 2 from power take off shaft (PTO) of the tractor to gear 9 of pump 4 of hydraulic lift
linkage and further by means of cylindrical gearing (gears 9,8,7) to pump 5 of transmission hydrau-
lic system.
Drive parts are located in casing 1. Oil for its lubrication comes in drive through hole in
cover 3. Oil is drained through nipple 6. This drive is full-time drive.
1 - casing; 2 –gear shaft; 3 – cover for lubricant supply into drive; 4 – variable displacement pump of
lift linkage hydraulik system; 5 – fixed displacement pump of transmission hydraulic system; 6 – nippel for
lubricant removal; 7, 8, 9 - gears.
