Single Parts Repair, Off-Season Inspection
or General Overhaul
Overhauling a tractor could be essentially
different in the following respects :
1) The repair of individual parts that has
failed during operation. This kind of
repair is by no means as easy as it may
seem at first sight, for replacing the
defective part may call for elaborate
and extensive dismantling and
reassembly procedures. Another
disadvantage of a “single parts repair”
is that it may have to be carried out
during the working season when the
tractor is most urgently needed. When
taking the preventive maintenance
measures as outlined below these
“single parts repairs” should, to a
great extent, be eliminated.
2) A fundamentally different procedure
is the “off-season inspection” when
all parts of the machine are checked
over. This procedure covers mainly the
following : Thorough cleaning of the
machine, re-setting and adjusting of
all units subject to a certain amount
of wear, replacing those parts which
still function but show such a degree
of wear that they are not likely to
survive the ensuing working season.
Off-season inspection is a thorough
preventive maintenance measure.
It calls for a well trained serviceman
with a detailed knowledge of the
tractor and the functioning of the
various units.
Off-season inspection is the best
guarantee for trouble free and
efficient performance. Repairs as
described in foregoing and following
chapters can be prevented. The term
“off-season” applies generally to the
winter months when the tractor is
seldom required to do any work.
During this period service stations do
not have much to do as a rule and
can give better service than during the
peak periods.
3) A rather expensive reconditioning job
is the “general overhaul”. It becomes
necessary when the tractor has been
kept on the job by “make-shift”
repairs without observing
fundamental maintenance rules. Worn
parts fail and other, potentially good
parts are often broken as a result of
these failures.
Apart from being a costly affair it very
often happens that this sort of repair
has to be made during the operating
season when work is pressing.
A general run down condition,
moreover, often causes small fissures
and cracks which can be overlooked
and are then the source of fresh
trouble.
Off-season inspection is the most
important measure of preventive
maintenance. The frequency of this
inspection should be determined by
the number of operating hours and
by operating conditions.
