No. 11) before bottoming on shaft shoulder, add two 0.020” shims behind impeller. Reinstall impeller. 12. Place pump in an upright position. Rotate shaft/impeller. Impeller cannot strike volute base or volute cover. If interference exists, install or remove shim washers behind the impeller. (See “SHIM ADJUSTMENT” section) If shimming does not correct interference, repositioning coupling/shaft/impeller assembly on motor shaft may be necessary. VOLUTE SPACER PLATE REPLACEMENT The volute spacer plate is subject to wear only by abrasive liquids. If badly, worn this plate can be replaced easily. 1. Disassemble pump for access as described in IMPELLER/MOTOR REPLACEMENT, steps 1, 2, 3, and 4. 2. Remove two fasteners (Ref. No. 12) that connect the spacer plate to the volute cover. 3. Replace spacer plate. 4. Reassemble pump as described in steps 11 and 12. SHIM ADJUSTMENT 1. When installing a replacement impeller (Ref. No. 14), motor (Ref. No. 1), volute spacer plate (Ref. No. 11) or volute base (Ref. No. 17), it may be necessary to adjust the number of shims (Ref. No. 9) to insure proper running clearance between impeller and volute base and spacer plate. Proceed as follows: NOTE: A proper running clearance between impeller and volute base is 0.04” to 0.06”. 2 1. For impeller or motor replacement, add one 0.020” shim in addition to those removed, if any, originally. 2. Reassemble pump as described in steps 9, 10, 11, and 12 as described in IMPELLER/MOTOR REPLACEMENT. IMPORTANT: Insure that volute base is snugly in place and check shaft to make sure it is turning freely (rotate impeller by using impeller nut Ref. No. 15 and socket wrench). Tighten fasteners connecting motor to column and volute to base carefully. Rotate shaft while tightening so that motor bearings are not damaged in the event that too many shims were installed. If shaft seizes before fasteners are completely tight, disassemble pump and remove two shims and repeat assembly. SHAFT SUPPORT REMOVAL Models 4445-95 and 4446-95 only. These units are designed to operate without a bottom bearing. A shaft support (Ref. No. 20) is installed at the factory to protect the shaft from misalignment during shipping. If pump is noisy while operating, this support may be the cause. The shaft support can be removed to stop noisy operation. Shaft support should not be replaced. 1. Disassemble pump for access as described in IMPELLER/MOTOR REPLACEMENT, steps 1 through 6. 2. Press out shaft support. Do not remove support plate (Ref. No. 21). 3. Reassemble pump as described in steps 10, 11, and 12. DEBRIS SCREEN CLEANING Sprayer/Washer pumps are equipped with a debris screen (Ref. No. 18). This screen is supplied attached to volute base (Ref. No. 17) with 4 drive pins. This screen may be replaced if damaged. If pump performance is reduced or severe vibration occurs during operation this screen may be clogged. Debris screen must be thoroughly cleaned to restore pump performance. 3 Repair Parts List Ref.
