5.6 Pump Replacement
The pump located in either the leak-gas or background-gas sensor
assembly (see Figure 5-5) may become inoperative due to water or solid
particles getting into the valves. This will require replacement of the
pump to correct.
Equipment Required:

5
/ 64 " Allen Wrench
 Replacement Pump Assembly (P/N 0055-0061)
Procedure:
1. Remove cover per Section 5.3.
2. Back off the pump-bracket screw using a
5
/ 64 " Allen wrench; then
rotate bracket arm to free pump. See Figure 5-6.
3. Unplug pump connector from printed circuit board and lift pump
straight up.
4. Install the new pump by lining up the pump’s inlet and outlet tubes
with the two flow block holes and pushing into place. Swing bracket
arm over pump and tighten—realigning pump as necessary to make a
proper fit.
5. Replace cover that was removed in Step 1.
