8.5 Preservation

off with compressed air to remove moisture. Damaged painting shall be restored by putting varnish and paint coating or protective grease. Painting shall be carried out according to GOST 6572-91. With long-term outdoor storage, electrical equipment, components made of rubber, polymer and textile materials (hydraulic circuit hoses, etc) shall be dismounted, prepared for storage and sent to a warehouse. Fastening parts of the tractor dismounted components shall be mounted back in their places. Electrical equipment (headlights, generator, starter, accumulator batteries) shall be cleaned, blown off with compressed air, terminals shall be coated with protective grease. When preparing a tractor for long-term storage, it is required to carry out inside and outside preservation procedures for the engine according to the engine operation manual. Lubricate all tractor units according to clause 3 of table 6.4 of the present operation manual. Drain oil and fill fresh oil with the required amount of additives up to the control level to the transmission and brake bodies, FDA and FPTO reducing gears, HLL and HSC oil tanks. Run in the tractor for 10-15 minutes. Put accumulator batteries in long-term storage after conducting control-training cycle in accordance with GOST 9590-76. Projecting joints, threaded connections of lift linkage mechanism, steering geometry, splined surfaces of PTO shaft end extension and of cardan shafts, and projecting parts of cylinder rods and shock absorbers, front and rear track adjusting mechanism shall be preserved. Cover carefully the fuel tank filling neck, diesel breather openings, transmission, hydraulic systems, the engine exhaust pipe and the inlet air cleaner pipe, relative openings after starter removal, and other cavities, through which atmospheric precipitation may get inside inner cavities of tractor assembly units with caps, polyethylene film sacks or other special accessories. Set shift levers and pedals to a position excluding spontaneous engagement of tractor units and implements. 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 decreased to 70% of the standard. It is required to 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, polyethylene film, etc). Cabin hoods and doors shall be closed. Maintenance during storage includes checking if machines are properly placed on supporting blocks (plates) (absence of cocking), completeness, air pressure in tires, airtightness, state of anticorrosion coatings (protective grease, paint integrity, absence of corrosion (integrity and fixing strength of casings and covers). Detected defects shall be eliminated. At regular intervals while long-term storage and during cold seasons, it is required to lubricate the cylinder mechanism located on button 3 (figure 3.22.4) of the door lock handle by method of injecting with lubricants HG 5503 (HG5501, WD-40). Tractor technological 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 adjustments of tractor and its components including the engine in accordance with the engine operation manual 260S2 – 0000100 OM.

8.5 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 260S2 – 0000100 OM.
