SECTION F: SERVICE AND REPAIR <br />NOTE: All item numbers in () refer to Figures 16 thru 21 <br />CAUTION! - Operating pump builds up heat and <br />A <br />pressure; allow time for pump to cool to room <br />temperature before handling or servicing. Slowly <br />remove pipe plug prior to servicing as housing <br />may be pressurized. <br />F-1) Lubrication: <br />Anytime the pump is removed from operation, the cooling oil in <br />the motor housing (6) should be checked visually for oil level <br />and contamination. <br />F-1.1) Checking Oil: <br />Motor Housing - To check oil, set unit upright. Remove pipe <br />plug (39) from housing (6). With a flashlight, visually inspect <br />the oil in the motor housing (6) to make sure it is clean and <br />clear, light amber in color and free from suspended particles. <br />Milky white oil indicates the presence of water. Oil level should <br />be just above the motor when pump is in vertical position. <br />F-1.2) Testing Oil: <br />1.) Place pump on it's side, remove pipe plug (39), from motor <br />housing (6) and drain oil into a clean, dry container. <br />2.) Check oil for contamination using an oil tester with a <br />range to 30 Kilovolts breakdown. <br />3.) If oil is found to be clean and uncontaminated (measuring <br />above 15 KV. breakdown), refill the motor housing as per <br />section F-1.4. <br />4.) if oil is found to be dirty or contaminated (or measures <br />below 15 KV. breakdown), the pump must be carefully <br />inspected for leaks at the shaft seal (28), cable assemblies <br />(16) and (56 if used), square ring (27) and pipe plug (39), <br />before refilling with oil. To locate the leak, perform a <br />pressure test as per section F-1.3. After leak is <br />repaired, dispose of old oil properly, and refill with new oil <br />as per section F-1.4. <br />F-1.3) Pressure Test: <br />Pumps that have had the oil drained from the Motor <br />Housing -Apply pipe sealant to pressure gauge assembly <br />and tighten into pipe plug hole (See Figure 4). Pressurize <br />motor housing to 10 P.S.I. Use soap solution around the <br />PRESSURE GAUGE ASSY <br />(SEE PARTS UST) <br />--+ri-- 10 PSI AIR <br />REMOVE PLUG -� <br />FIGURE 4 <br />10 PSI AIR <br />REMOVE PLUG <br />i <br />NOTE: THiS PLUG FOR <br />"DS' MODELS ONLY <br />11 <br />sealed areas and inspect joints for "air bubbles". If, after <br />five minutes, the pressure is still holding constant, and no <br />"bubbles" are observed, slowly bleed the pressure and <br />remove the gauge assembly. Replace oil as described in <br />section F-1.4. If the pressure does not hold, then the leak <br />must be located and repaired. Pumps that have NOT had <br />the oil drained from the Motor Housing - The pressure <br />test may be done with the oil at its normal level. Remove <br />pipe plug (39) from motor housing (6). Apply pipe sealant to <br />pressure gauge assembly and tighten into hole (see Figure <br />4). Pressurize motor housing to 10 P.S.I. Use soap solution <br />around the sealed areas above the oil level and inspect joints <br />for `air bubbles". For sealed areas below the oil level, leaks <br />will seep oil. <br />If; after five minutes, the pressure is still holding constant, <br />and no "bubbles"toil seepage is observed, slowly bleed the <br />pressure and remove the gauge assembly. If the pressure <br />does not hold, then the leak must be located and repaired. <br />Seal Chamber (DS Units Only)- Set unit on its side with <br />fill plug (44) downward, remove plug (44) and drain all oil <br />from seal chamber. Apply pipe sealant to pressure gauge <br />assembly and tighten into hole in outer seal plate (29). <br />Pressurize seal chamber to 10 P.S.I. and check for leaks as <br />outlined above. <br />CAUTION i - Pressure builds up extremely <br />r : ( fast, increase pressure by "TAPPING" air <br />i nozzle. Too much pressure will damage <br />seal. DO NOT exceed 10 P.S.I. <br />F-1.4) Replacing Oil: <br />Motor Housing- Set unit upright and refill with new cooling <br />oil as per Table 1 (see parts list for amount). Fill to just above <br />motor as an air space must remain in the top of the motor <br />housing to compensate for oil expansion (see Fig 16, 18 or <br />20). Apply pipe thread compound to threads of pipe plug (39) <br />then assemble to motor housing (6). <br />IAIMPORTANTI - For single phase units, oil level <br />should be below capacitor. <br />Seal Chamber (DS Units Only)- Set unit on its side, with <br />plug (44) upward, and refill with new oil as per Table 1 (see <br />parts fist for amount). Apply pipe thread compound to threads <br />of pipe plug (44) and assemble to outer seal plate (29). <br />WARNING 1- DO NOT overfill oil. <br />Overfilling of motor housing with oil <br />p ` can create excessive and dangerous <br />hydraulic pressure which can destroy the <br />pump and create a hazard. Overfilling oil <br />voids warranty. <br />TABLE 1 - COOLING OIL - Dielectric <br />SUPPLIER <br />GRADE <br />BP <br />Enerpar SE100 <br />Conoco <br />Pale Paraffin 22 <br />Mobile <br />D.T.E.
