6-42. TABLE OF LIMITS. The minimum and maximum
limits in the following Table of Limits represent ideal
limits. Measurements not exceeding the replacement
maxi-mum permits the part to be retained in service.
Parts for which tolerances are given are not necessarily
reusable if they are otherwise worn or damaged,
although their dimensions may be within these specified.
6-43. Refer to Table 6-1 for wear limits, end play,
clearances, and backlash, as applicable. Refer to Table
6-2 for spring data and specific torque limits.
6-44. TEST. The following paragraph contains all the
nec-essary operating instructions and tests to be
performed after repair of the air compressor unit to
ensure satisfactory operation. To perform the tests,
proceed as follows:
Refer to LUBRICATION INSTRUCTIONS (Section V)
and make certain air compressor unit is properly
lubricated. To perform the tests, proceed as follows:
Make certain CLUTCH operating rod (11, Figure
4-2 is in disengaged position, away from control panel.
switch (16, Figure 4-2) is in the UNLOAD position and
close all control panel valves.
Make certain ENGINE THROTTLE CONTROL
(10, Figure 4-2) is positioned half way in (idle position, 1,
000 + 100 rpm [1, 100 + 100 r/min]).
Turn MASTER SWITCH (9, Figure 4-2) to 450
If engine oil pressure does not register on gauge within
five seconds, immediately shut down engine and
determine cause. Refer to TROUBLESHOOTING
Push engine START switch (8, Figure 4-2).
When engine starts continue to hold START switch until
EN-GINE OIL PRESSURE gauge (6, Figure 4-2)
registers pres-sure; then, release START switch.
If compressor oil pressure does not register within 5
seconds, shut down engine, and determine cause. Refer
