Automatic Lube System
Injectors (SL-1)
a. Each lube injector services only one grease point.
b. Injectors are available in banks of two, three, four
and five as well as single replacement units.
c. Injector output is adjustable:
Maximum output = 0.08 in
Minimum output = 0.008 in
d. In case of a pump malfunction, each injector is
equipped with a covered grease fitting to allow the
use of external lubricating equipment.
Injector Adjustment
The injectors may be adjusted to supply from 0.008 in
3
to 0.08 in
(0.13 cc to 1.31 cc) of lubricant per injection
cycle. The injector piston travel distance determines
the amount of lubricant supplied. This travel is in turn
controlled by an adjusting screw in the top of the
injector housing.
Turn the adjusting screw (2, Figure 4-8) counterclock-
wise to increase lubricant amount delivered and clock-
wise to decrease the lubricant amount.
With the Solid State Timer set at 20 minutes, the
recommended setting is:
4 turns clockwise from the maximum counter-
clockwise position. This delivers approximately
3
0.04 in
(.66 cc) of lube per cycle.
When the injector is not pressurized, maximum injector
delivery volume is attained by turning the adjusting
screw (2) fully counterclockwise until the indicating pin
(1) just touches the adjusting screw. At the maximum
delivery point, about 0.38 inch (9.7 mm) adjusting
screw threads should be showing. Decrease the deliv-
ered lubricant amount by turning the adjusting screw
clockwise to limit injector piston travel.
If only half the lubricant is needed, turn the adjusting
screw to the point where about 0.19 inch (4.8 mm)
threads are showing. The injector will be set at mini-
mum delivery point with about 0.009 inch (0.22 mm)
thread showing.
NOTE: The foregoing information concerns adjust-
ment of the injector delivery volume. The timer adjust-
ment should also be changed, if overall lubricant
delivery is too little or too much. Injector output should
NOT be adjusted to less than one-fourth capacity.
