5-11. FLOW TEST (Contd)
Install burnishing tool (6) in test stand inlet pressure line adapter (15).
6.
NOTE
With burnishing tool needles retracted, burnishing tool can be left
in adapter during entire test.
Retract burnishing tool needle (14) by pulling knob (13) out.
7.
8.
Connect inlet pressure line adapter (15) to burnishing tool adapter inlet hole (16).
Install drain connector (11) on burnishing tool adapter inlet hole (12).
9.
10.
Clamp injector (7) in place by opening air valve (9).
Close hydraulic valve (8) to lock injector (7) in place.
11.
CAUTION
Temperature should read 90-95F (32-35C). If temperature
exceeds 135F (57C), drain and replace with new test oil.
Place motor switch (3) in start position.
12.
Adjust regulator knob (10) until pressure gage (1) reads 120 psi (827 kPa).
13.
14.
Press red flow start switch (4) until counter (5) reads the same as master injector counter strokes.
NOTE
Correct reading is 121-122 cc at 120 psi (827 kPa). If reading is
higher, follow steps 17 through 26 to install new orifice plug.
However, if reading is lower continue flow test step 34.
15.
Observe reading on vial (2).
16.
Remove test stand inlet pressure line adapter (15) from burnishing tool adapter inlet hole (16).
