5800 Refrigerated Sampler Service Guide Section 2 Sample Delivery System 2.3.5 Pump Motor and Wiring 1. Free the motor from the module’s wiring by cutting the plastic cable tie. 2. Remove the nut and optical disk from the pump shaft. 3. Remove the four large Phillips screws holding the motor plate on the base. Cut tie Remove screws (4) Figure 2-12 Removing pump motor assembly 4. Remove the four large Phillips screws that mount the motor to the plate. Do not remove the motor gear from the motor shaft. Replace as an assembly. The brass idler gear bushing engages with the idler gear shaft. When seating the idler gear, first lubricate its shaft with grease. The black plastic bushing (also known as the thrust bushing) normally rests on the shaft of the drive gear, acting as a spacer (Figure 2-13). If replacing one or both of the bushings, ensure that the bushing flanges rest on the motor gear side (bottom) of the plate (Figure 2-13).

5800 Refrigerated Sampler Service Guide Section 2 Sample Delivery System 2.3.6 Motor Replacement When installing the motor and plate assembly, attach the plate to the base using the original four holes to insert the mounting screws (see Figures 2-12 and 2-14). The unused holes should only be used if the original threaded holes are damaged. Tighten the screws to 20 - 28 in/lbs. CAUTION When reinstalling all self-tapping screws, avoid destroying the plastic threads. First, seat each screw in its hole and, without pressing down, rotate the screw counter-clockwise until it falls into its thread groove with a "click." Then tighten the screw. This precaution is not necessary with new, unthreaded holes. Spare mounting holes (3) Original mounting holes Figure 2-14 Pump motor plate Wiring assembly The motor wiring harness is easily replaceable. 1. Un-solder the two wires from the motor terminals. 2. When installing the new harness, solder the red wire to the red terminal and the black wire to the black terminal. 3. Route the wires so that the ferrite bead is on top of the motor (refer to Figure 2-15). 4. Clamp all four wiring harnesses to the motor body with a cable tie. 2-11
