INJECTOR CYCLE INDICATOR OPERATION
The injector cycle indicators are attached to the output side of
aluminum injectors installed in an in-line manifold only. During
the lube cycle, they provide a visual indication that the injector
has cycled. Figure 13 represents an injector cycle indicator. As the
pump pressurizes the injector, the injector piston moves toward
the outlet, pushing a measured amount of lubricant toward the
lubrication point. This piston contacts the plunger of the indicator
moving it in the same direction. As the plunger moves toward the
indicator outlet, the indicator stem is pushed toward the end of
the indicator. This opens the outlet of the indicator releasing the
lubricant and extends the indicator stem past the indicator body.
This gives an indication that the injector has cycled.
When the pump has completed its cycle, and the injector piston
has retracted, the spring-loaded indicator stem retracts, leaving
the end of the stem fl ush with the indicator body and sealing the
outlet port of the indicator.
The outlet of the injector cycle indicator accepts 1/8 inch tubing.
DIMENSIONS
Injectors
All manifold injectors are approximately 2.125 inches (54 mm)
long with a 0.625 inch (15.88 mm) hex body. For injectors utilizing
from one to four output adjustment spacers add 0.04 inch (1 mm)
per spacer to the length.
All bearing point injectors are approximately 2.5 inches (63.5 mm)
long with a 0.625 (15.88 mm) hex body. For injectors utilizing from
one to four output adjustment spacers add 0.04 inch (1 mm) per
spacer to the length. Figure 14 provides dimensions for the two
types of injectors.
Manifolds
Figures 15 and 16 provide dimensions for aluminum and stainless
steel manifolds.
