6.2 WEEKLY INSPECTION Thefollowingweeklyinspection of enginesshould be madebythepomper or qualifiedengineoperator, who sbouldalsorecordeachinspectionperformed.
6.2.1 DailyInspectionItems All of thedailyinspectionitemsasgivenin 6. 1 should alsobeperfonned in theweeklyinspecti
6.2.2 Cleaning If necessary, the engine exterior should be thoroughly cleaned with a mild solvent (not gasoline), and compressed air or hot water should be used for flushing and drying. Care should be taken not to wash or blow dirt into inaccessible locations behind filler openings or into ignition or injection equipment; or on air-cooled engines, into the fins on heads and cylinder blocks. Always dry and relubricate governor and control linkage joints after flushing engine.
6.2.3 Water Pump Water-pump scals should be inspected and packing on packed-type pumps should be tightened or replaced, if necessary.
6.2.4 Fan Belts Fan belts should be checked for proper tension and tightened or loosened, if needed.
6.2.5 Lubricatlon of Generator and Accessories The generator should be lubricated with a few drops of oil and the accessories lubricated according to the instructions of the manufacturer.
6.26 Power Take-Off Clutch The power take-off clutch should be lubricated and ad- justed, if required, according to the instructions of the manufacturer, but care should be taken not to over-lubricate.
6.27 Gas Regulators Gas engines should be checked for gas pressure at the pri- mary and final regulators.
6.2.8 Breather Elements All removable breather elements sbould be carefully cleaned and wasbed in mild solvent (not gasoline), and the oil changed on those elements requiring re oiling. Follow in- structions carefully on dry type clement service.
6.2.9 Fuel Stralners Dicsel fuel system strainers should be cleaned and filters replaced if scheduled.
6.3 MONTHLY INSPECTION The following monthly inspection should be performed by an expert mechanic who should aIso record each inspection performed.
6.3.1 Dally and Weekdy Inspectlon items AlI of the daily and weekly inspection items as given in 6.1 and 6.2, respectively, should also be performed in the monthly inspection.
6.3.2 lgnitlon System On spark-ignition engines the following ignition devices, depending upon the type used, should be checked:
a. magneto-point condition and clearance timing
b. the impulse functioning
C. the spark-plug gap and heat range d. the distributor condition with respect to the automatic advance mechanism.API RP 7C-11F pdf download.API RP 7C-11F:2008 pdf free download
