f. Fuel Inject Pump Bench Test.
(1) General. The bench test procedure is based on the following renditions:
(a) Injection lines are 3/32 inch ID by 30 inches long.
(b) Fuel readings are based on fuel with a viscosity of 34-36 SSU at 100°F.
(c) Fuel temperature at 110° to 115°F.
(d) Nozzles, part number 12SD12, adjusted to opening pressure of 2500 psi (170 ATS).
(2) Test procedure.
Mount pump securely in diesel injector test stand using a suitable adapter. The drive adapter,
usually with a ball bearing, supports the shaft. This pump must be tested with an intermediate
support bearing. Install high pressure injection lines using new gaskets. Leave fuel line connector
screws at pump and injection line nuts at the nozzles loose. Install fuel inlet and return lines. Install
transfer pump pressure gauge with a shutoff valve as close to the transfer pump as possible.
Transfer pump pressure gauge must be isolated by shutoff valve at the fuel injection
pump when checking fuel delivery and advance movement.
Set counter and tachometer switches to clockwise position.
