Preservation; Depreservation And Represervation - Belarus 922.6 Operator's Manual

Only unloaded pneumatic tires are allowed for outdoor storage on tractors, resting on
supports. Tire surface shall be covered with protective agent. Tire pressure shall be de-
creased to 70% of the standard. It is required to clean exterior surfaces of the hydraulic sys-
tem flexible hoses off mud and oil. Hoses may be kept on the tractor. In this case they are
coated with protective substance or wrapped with insulating material (wax paper, polyeth-
ylene film, etc).
Cabin roofs, hoods, screens and doors should be closed.
At regular intervals, in cold weather and in case or long-term storage lubricate the cylin-
der mechanism, located in button 2 (Figure 2.22.1) of the door lock handle by injection using
agents HG 5503 (HG5501, WD-40).
Maintenance during storage includes checking if machines are properly placed on
supporting blocks (plates) (absence of cocking), completeness, air pressure in tires, air-
tightness, state of anticorrosion coatings (protective grease, paint integrity, absence of cor-
rosion (integrity and strength of sheathes and covers). Detected defects shall be eliminated.
Tractor technical maintenance when removing from storage includes taking off sup-
porting blocks, cleaning and if required depreservation of tractor, its components, removal of
packoff, reinstallation of dismounted components, tools, check of operation and adjustments
of tractor and its components, including its engine according to the engine manual..

7.5 Preservation

Preservation provides provisional anticorrosion protection of tractor assemblies and
systems from ambient exposure in the process of tractor transportation and storage.
Engine and its systems preservation instructions are listed in the engine operation
manual.
It is required to clean tractor surfaces subject to preservation from mechanical stain-
ing, degrease it and dry up. It is required to cover unpainted inside and outside galvanized
surfaces, specific assemblies of tractor and cabin with corrosion-proof oil RUST BAN 397,
SUMIDERA 397.
Protecting lubricants according to GOST 4366-76 shall be applied to the projecting
parts of the hydraulic cylinders and shock absorbers.
Hermetic sealing of units (radiator and fuel tank and SRC system liquid filler, breath-
ers) shall be carried out using polyethylene film cases.
The applied materials provide tractor protection and its assemblies for the period of
storage and transportation within one year.
Outside tractor and its assemblies preservation shall be made by lubrication of sur-
faces with a brush or sputtering by means of a paint sprayer. Inside tractor preservation is
carried out by filling cavities with preservation mixture and subsequent engine operation.
During tractor inter-shift, short-term and long-term storage, the enterprise operating
the tractor shall be responsible for compliance with preservation methods and storage con-
ditions specified in GOST 7751-85. Inside tractor surface preservation shall be carried out
with preservation grease КS-U according to TU RB 600125053.019-2004. When a tractor is
stored outside, specific surfaces shall be preserved with grease "BELA-COR" of type "А"
according to TU RB 600125053-020-2004. Upon agreement with OJSC Minsk Tractor
Works other preservation greases can be used.

7.6 Depreservation and represervation

Depreservation method is chosen depending on preservation materials used. Surfac-
es under preservation shall be wiped with cleaning cloth soaked with low-viscous oils, sol-
vents, or washed away with washing water-soluble detergents. Sealed assembles shall be
cleaned from insulation materials (film, paper). Inside surfaces under preservation do not
need depreservation.
Tractor represervation is carried out in case conservation defects are detected in the
process of storage or upon expiration of protection life.
