Assembly Instructions

Tip assembly over and tighten fixture bolt with wrench hand-tight.

Note: See Special Tools Section (pages 10-11) for fixture bolt size.

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.

Place bracket on vertical build fixture.

Note: See Special Tool Section (pages 10-11) for fixture dimensions.

Bronze bearing pre-installed into motor bracket.

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'.

Install sand collar onto shaft and push over bracket bearing until seated.

Tighten sand collar set screws to 100-120 lb-in.

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.

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.

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.

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.

Lift pump with proper support and lay down horizontal.

CAUTION: Prevent from rolling.

Apply Loctite® 243 to the motor coupling set screws. Install set screws so they are clear of the keyway.

Tighten set screws onto key.

Torque Values:5x6, 6x6, and 8x6 = 50-60 lb-in.8x8 = 100-120 lb-in.

Install upthrust bolt in discharge until contact is made with top of shaft and all downplay is taken up.

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"

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.

Remove spacer and tighten lock nut against discharge, holding bolt constant with no rotation.

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).
