IMPROVEMENT OF DIESEL, SKIDDING TRACTORS;
CUT IN METAL CONSUMPTION
STRESS FURTITR IMPROVEMENT OF TRACTORS' QUALITY -- Moscow, Avtomobil'naya i
Traktornaya Proaprshlennoct', Mar 52
The movement initiated by the Ural Automobile Plant imeni Stalin to in-
crease the life of the ZIS-5 truck has evoked a broad response from tractor
builders. A special conference of designers from tractor plants and scientific
workers of NATI (State Union Scientific Research Tractor Institute) outlined
measures to increase the life of DT-54 and KD-35 crawler tractors to 3,000 hours
(instead of 2,000 hours) and of Universal wheel tractors to 2,000 hours (in-
stead of 1,500 hours).
To achieve these goals, designers should utilize the properties of new ma-
terials and avoid the old method of increasing the strength and life of parts
by increasing their weight. Experience has shown that the weight of parts,
aggregates, and machines as a whole can be reduced, with a simultaneous increase
in their strength and life, by using progressive design methods and technical
processes.
Severe operating conditions of tractors, especially in plowing (protracted
operation at full load under field conditions), compel designers to pay special
attention to mating parts, to all types of seals, and also to the system of
filtering and cleaning air, fuel, and oil.
After long, concentrated research on seals, designers of the Kharkov Trac-
tor Plant have built a new self-tightening gland which lasts much longer owing
to the replacement of leather by rubber.
However, questions connected with the best methods of sealing the fuel
system, the water pump, and the side drive have not yct been solved. Existing
air cleaners have design faults which contribute to increased wear of moving
parts of the engine. Because of vibration of the air cleaner, breaking of the
hermetic seal of the intake lines, unsatisfactory seals, and short life of the
glass dust collector, dust enters the engine, evading the air cleaner.

Among the corrective measures outlined are: increasing the wear resistance
of parts by surface hardening, by surface covering, by replacing one material
with another, and by developing stronger designs. These measures would take the
form of chromeplating piston rings, hardening sleeves with high-frequency cur-
rents, strengthening crankshaft fillets by burnishing them with rollers, improv-
ing the quality of gears in splined joints, and improving the strength of hous-
ings.
One of the pzimary tasks of tractor plants and of NATI is to lengthen the
life of caterpillar tracks. Along with the production of new caterpillar links,
tractor builders should further improve all parts of the undercarriage to make
them equally strong. Among the necessary measures are: improving gearing,
strengthening of the drive sprockets and link cogs, general strengthening of the
links, introduction of reliable seals, etc. Individual projects along these
lines have already produced good results.
Thus, by reviewing the design of the caterpillar links of the KD-35 tractor
and a+-ngthening them, NATI and the Design Bureau of the Lipetsk Tractor Plant
have already lengthened the life of the tracks. All work on caterpillar tracks
must be completed in 1952.
Better maintenance is needed to lengthen the life of tractors. Use of
quality lubricants, quality repair, and improvement of the qualifications of
tractor drivers should not be the responsibility of the MI5 alone. Complete
and authoritative guides to the care and operation of tractors should be pub-
lished.
TEST MODERNIZED SKIDDING TRACTOR -- Petrozavodsk, Leninakoye Znamya, 27 Apr 52
The Luga Timber Management has completed field tests of the improved skidd-
ing tractor built by the Leningrad Forertry Engineering Academy imeni S. M.
Kirov in coo eration with the Lenlea (Leningrad Timber) Trust
The tractor has a lengthened frame and a new gas generator engine which is
more powerful than those on former skidding tractors. The tests showed that
the weight of the load is distributed evenly over the whole tractor. The trac-
tor's operating qualities have been improved, and it is 40 percent more produc-
tive than the series-produced skidding tractor.
AUTO WORKERS SAVE METAL -- Moscow, Vechernyaya Moskva, 8 Apr 52
In the course of 2 months, the Moscow Automobile Plant imeni Stalin has
adopted measures that will save 2,354,000 rubles' worth of metal yearly.
Krylov, chief engineer of the plant, stated that if the plant worked ac-
cording to 1948 metal-consumption norms, it would require an additional
30,000 tons of metal a year.
Moscow, Komsomol'skaya Pravda, 13 Apr 52
Workers of the Moscow Automobile Plant imeni Stalin have developed measures
for saving metal in the production of 3,242 parts and 12 large units of vehicles
put out by the plant. Since the competition for saving metal started 3 months
ago, the consumption of ferrous bar stock has been reduced by 11.3 kilograms;
of cast iron, 2.8 kilograms; and of nonferrous metals, 1.25 kilograms for each
ZIS-150 truck produced.

Moscow, Moekovskaya Pravda, 22 Apr 52
At the Moscow Automobile "lent imeni Stalin, workers have reduced the con-
sumption of ferrous metals by 20.8 kilograms and of nonferrous metals by 6.95
kilograms for every bus produced.
PIAIfr SAVES METAL -- Moscow, Vechernyaya Moskva, 10 Apr 52
In 1951, the automatics shop of the Moscow Small Displacement Automobile
Plant saved 36 tons of gauged steel and 5 tons of nonferrous metal, and the
plant as a whole saved 200 tons of ferrous and nonferrous metal. In the same
period, the shop saved 132,000 rubles by increasing the length of time between
equipment repairs. At the beginning of 1952, 30 percent of the shop's equip-
ment was rated excellent, 65 percent was rated good, and 5 percent was rated
satisfactory. In the last 6 months of 1951, the shop saved more than 195,000
rubles by reducing the cost of every operation, and in Ja uary and February
1952, the plant saved about 75,000 rubles by this method.
At one time, rejects in the automatics shop were as high as 2.3 percent.
nejects were lowered from 0.9 percent in January 1951 to 0.1 percent in January
lYSc.
Uncompleted production was reduced from 25,000 rubles in the first quarter
of 1951 to 1,600 rubles in the third and fourth quarters.
The shop saved 1,065,000 rubles above the plan in 1951. -- N. Voronkov,
Chief of the automatics shop, Moscow Small Displacement Automobile Plant.
TO SERIES-PRODUCE DUMP TRUCKS -- Tbilisi, Zarya Vostoka, 30 Mar 52
The Kutaisi Automobile Plant recently shipped a large consignment of trucks
to enterprises of the Ministry of Petroleum Industry USSR.
The plant has finished preparations for series-producing KAZ-585 dump
trucks, and will ship a large consignment of these trucks to the construction
projects in the second quarter of 1952.
Tbilisi, Zarya Vostoka, 5 Apr 52
The main assembly shop of the Kutaisi Automobile Plant fulfilled its first
quarter 1952 plan on 25 March.
Moscow, Pravda, 8 May 52
The Kutaisi Automobile Plant has produced the first KAZ-535-B dump truck.
The improved truck has a mechanism which automatically opens end closes the
back.
