Recommended Equipment Machinery & Tools: The minimum basic hand tools and equipment needed for submersible turbine assembly: Assembly Fixture Kit 305386901 (See special tools section, pg 10-11 for additional information) 5 x 5/6 x 6 Collet Hammer 305385101 8 x 6/8 x 8 Collet Hammer 305385102 Allen Wrenches SAE or Standard (preferably T-handle design) 5/32" is used for sand collar set screws 1/8" is used for motor coupling set screws 3/8" for STS upthrust adjustment Combination wrench or socket and ratchet set 5/16" for cable guard screws 7/16" for 6" sub turbine bowl bolts 9/16" for 8" sub turbine bowl bolts 1-1/8" for upthrust lock nut Flat head or standard large screwdriver Ballpeen hammer Set of 1/8" stamps for imprinting nameplate information and date code Dow Corning 111 Valve Lubricant & Sealant (food grade grease) Loctite 243 Fine emery cloth or steel wool for de-burring purposes. Additional machinery and/or equipment will be required if the assembler desires the ability to cut and de-burr shafting and cable guards or remove and install bronze bearings. Optional tool available: 305471902 5" or 6" STS Bowl Bolt Assembly Tool 305471998 8" STS Bowl Bolt Assembly Tool 2
Assembly Instructions 1 Place bracket on vertical build fixture. Note: See Special Tool Section (pages 10-11) for fixture dimensions. Bronze bearing pre-installed into motor bracket. 1 2 Inspect shaft straightness. Pump shaft must be straight to within 0.002" total indicator runout (TIR) when shaft is supported at each end. Shaft straightening should be done mechanically without using heat. Note: If shafts are cut to length be sure cut is square and chamfer end. Shafts offered cut to length for standard stage counts and as double keyed sections in lengths of 4', 6', 8' and 10'. 2 3 Tip assembly over and tighten fixture bolt with wrench hand-tight. Note: See Special Tools Section (pages 10-11) for fixture bolt size. 3 4 Apply Loctite 243 to set screws of sand collar. Thread set screws into sand collar. Make sure set screws do not stick out into ID of sand collar. 4 3
Assembly Instructions 5 Install sand collar onto shaft and push over bracket bearing until seated. 5 6 Tighten sand collar set screws to 100-120 lb-in. 6 7 Install impeller onto shaft and position bottom against bracket/bowl. Slide collet onto shaft and position into impeller. A flat screwdriver may be needed to spread collet while sliding. Note: When using a mix of impeller trims, always start the sub turbine build with the largest impeller diameter, A-Trim, followed by the B-Trim, and ending with the C-Trim impellers. 7 8 Drive collet into impeller using the collet drive hammer. Collet will not drive flush. Continue to hammer collet until impeller is secure on sub turbine shaft. 8 4
Assembly Instructions 9 10 11 Slide bowl onto shaft. Note: For 6" STS, please align cable guard indentions on outside of bowl. Secure bowl with bowl bolts (Impact or torque wrench recommended). 5" STS: Torque bolts to 10-12 lb-ft. All stages will receive 12 bolts. 6" STS: Torque bolts to 10-12 lb-ft. Stages 1 thru 9 will receive 8 bolts. The top of stage 9 and higher will receive 14 bolts due to the use of XP bowls. Note: For 100 gpm 6" STS pumps longer than 13 stages, after installing the 10th bowl, use three.030 shims between the next set of bowls as depicted in the picture. Tighten bowl bolts to snug. After bowl bolts are snug, install the impeller and collet. Next, remove the shims and tighten the bowl bolts normally. Repeat shimming procedure for all remaining stages until all impellers are installed. 8" STS: Torque bolts to 17-20 lb-ft. Stages 1 through 12 will receive 8 bolts. The top of stage 13 and higher will receive 16 bolts due to the use of XP bowls. Repeat process from Step 7 thru 10 for all stages up to last bowl. Do not install an impeller between last bowl and discharge bracket. 9 10 10 Note 11 12 Press top bearing into top bowl assembly. 12 5
Assembly Instructions 13 Fill discharge 1/4 full with Dow Corning 111 grease. 13 14 Attach discharge with bolts as in steps 10-11. 6" & 8" STS: ensure the cable guard holes on the discharge are lined up with the cable guard holes on the motor bracket. 14 15 Lift pump with proper support and lay down horizontal. CAUTION: Prevent from rolling. 15 16 Remove fixture bolt from pump shaft. Use impact wrench as necessary. 16 6
Assembly Instructions 17 Place key on pump shaft as shown. 17 18 Apply Loctite 243 to the motor coupling set screws. Install set screws so they are clear of the keyway. 18 19 Slide coupling onto shaft, aligning key, until seated. 19 20 Tighten set screws onto key. Torque Values: 5x6, 6x6, and 8x6 = 50-60 lb-in. 8x8 = 100-120 lb-in. 20 7
Assembly Instructions 21 Apply a small bead of Loctite 243 to upthrust bolt. 21 22 Install upthrust bolt in discharge until contact is made with top of shaft and all downplay is taken up. 22 23 Unscrew bolt and nut together until upthrust spacer can be installed between nut and discharge bearing housing. 5" or 6" STS - Spacer thickness = 0.221" 8" STS - Spacer thickness = 0.250" 23 Note: An alternative procedure to using the spacer is to back out the 5" or 6" STS upthrust bolt 2 1/4 turns or the 8" STS upthrust bolt 2 1/2 turns, then secure the position by tightening the lock nut. 24 Remove spacer and tighten lock nut against discharge, holding bolt constant with no rotation. 24 8
Assembly Instructions 25 Install nameplate onto bracket. 25 26 Install suction screen using supplied drive screws. 26 27 Cable guard installation. 5" STS: Install cable guard using supplied screws and cable clamp. Torque screws to 20-23 lb-in. Install cable clamp between the discharge and top bowl, as noted in picture. 6" STS: Install cable guard using supplied screws. Torque screws to 20-23 lb-in. 8" STS: Install cable guard using supplied screws. Torque screws to 20-23 lb-in. NOTE: 6" motor installations require 8x6 transition piece (305471001). 27 9
