Section 5 - Fuel System - Group 05 Fuel Pump - Cleaning and Inspection for Reuse (5-01) M11 Page 5-3 Inspection Visually inspect the fuel pump body and front support for cracks or other damage. Visually inspect the fuel pump assembly for damaged capscrews and damaged or loose fuel fittings. Visually inspect the drive coupling lugs for excessive wear or damage. Visually inspect the drive coupling spider for cracks or other damage. Visually inspect the front support pilot to make sure the pilot is continuous without cracks or gaps. Check the relative motion between the coupling and shaft using the indicator level and angle service tool, Part No. 3375855.
Hold the drive shaft stationary, and record the difference between angular values obtained at the ex- tremes of motion. If the relative motion exceeds 15 de- grees, then replace the coupling and shaft. Turn the fuel pump shaft by hand. The shaft must rotate freely. NOTE: If the shaft does not rotate freely, the pump must be disassembled for further inspection. Refer to Fuel Pump - Rebuild (5-02).
