5.2. RUNNING-IN OF TRACTOR
A new tractor should be run in during the
first hours, not less than 30 hr. Running-
in is a mandatory procedure to be fol-
lowed before putting the tractor into ser-
vice. In the process of running-in tractor
parts bed in and, thus, contribute to their
long-term service. Insufficient, or incor-
rect, running-in results in a considerably
shortened service life of the tractor.
IMPORTANT!
DO NOT attempt tow starting of a new,
not run-in diesel-engine, lest untimely
and excessive wear of diesel-engine
parts results.
Before proceeding with the running-in, be
sure to perform all recommendations on
maintenance operations listed under 7.1.
Thereafter, proceed with running the die-
sel-engine under idling for 15 min.: 5 min.
at minimum r.p.m. and 10 min. with gradu-
al inc rease in engine speed up to maxi-
mum. Running-in should be performed us-
ing the tractor on light-duty field jobs (sow-
ing, cultivation, haying, haulage jobs) us-
ing the hydraulic system. Load the diesel-
engine to not more than 50 percent of its
rated power. DO NOT overload the diesel-
engine. See that the diesel-engine shows
no smoky exhaust or crankshaft r.p.m.
drop. During the running-in period keep
watch over the operation of all tractor
mechanisms, listen, from time to time, to
the diesel-engine and transmission run in
all duties, watch over instrument readings.
Upon completion of the tractor running-un
under load, service the tractor in accord-
ance with the requirement under 7.1. Be-
ing convinced that the tractor is in good
repair, proceed with putting it to routine
service. The first 50 hours of tractor opera-
tion under service condition should be su-
pervised by a
mechanical engineer from
the dealer office
.
