Preservation; Depreservation And Represervation; Putting Tractor Into Operation After Long-Term Storage - Belarus 1221.6 Operator's 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, its systems and fuel tank 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.
Preservation of units (radiator and fuel tank filler, breathers, cylinder rods) 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 Minsk Tractor Works other preservation
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
should be stripped off insulation materials (film, paper). Inside surfaces under preservation
need no depreservation.
Tractor represervation is carried out in case conservation defects are detected in
the process of storage or upon expiration of protection life.

7.7 Putting tractor into operation after long-term storage

Perform depreservation of an engine according to the engine operation manual.
Remove grease off external surfaces under preservation. Dismount protective covers,
plugs, special accessories and mount the parts which were removed earlier back in their plac-
es. Before mounting parts clean them off grease and dust. Drain sediment out of all vessels,
fill them with operation fluids and, if necessary, top up to control level.
Lubricate all tractor mechanisms according to clause 3 of Table 5.8.1 of the present
operation manual. Carry out scheduled maintenance. Run tractor for 15-20 minutes. Correct
detected faults if necessary.
