Preservation; Depreservation And Represervation - Belarus 1220.6 Operator's Manual

polyethylene film sacks or other special accessories. Set shift levers and pedals to a posi-
tion excluding spontaneous engagement of tractor units and implements.
Only pneumatic tires unloaded are allowed for outdoor storage on tractors, resting
on supports. Tire surface should be covered with protective agent. Tires pressure should
be decreased up to 70% of the standard. Clean exterior surfaces of the hydraulic system
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 roof, hoods, screens and doors should be closed.
At regular intervals, in cold weather and in case orl ong-term storage lubricate the cyl-
inder mechanism, located in button 2 (Figure 2.21.1) of the door lock
ing agents HG 5503 (HG5501, WD-40).
Maintenance during storage includes checking if tractor is properly placed on sup-
porting 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 should be cor-
rected.
Tractor maintenance when removing from storage includes taking off supporting
blocks, cleaning and, if required, depreservation of tractor, its components, removal of
packoff, reinstallation of dismounted components, tools, check of operation and adjust-
ments 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.
Clean tractor surfaces subject to preservation from mechanical staining, degreased
and dried up. 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 cylinder rods.
Preservation of units (radiator and fuel tank and SRC system liquid filler, breathers)
is carried out by polyethylene film.
Materials used provide protection of tractor and its assemblies for the period of
storage and transportation within one year.
Outside tractor and its assemblies preservation is made by lubrication of surfaces
using brush or sputtering by means of 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 is liable for compliance with preservation methods and storage conditions speci-
fied in GOST 7751-85. Inside tractor surfaces preservation is carried out by preservation
grease КС-У according to TU RB 600125053.019-2004. When a tractor is stored outside,
specific surfaces must be preserved with grease "BELA-COR" of type "А" according to TU
RB 600125053-020-2004. Upon agreement with OJSC Minsk Tractor Works other preser-
vation greases can be used.

7.6 Depreservation and represervation

Depreservation method is chosen depending on preservation materials used. Sur-
faces under preservation have to be wiped with cleaning cloth soaked with low-viscous
oils, solvents, or washed away with washing water-soluble detergents. Sealed assembles
