SHIM ADJUSTMENT
When installing a replacement impeller (Ref. No. 13) or motor (Ref. No. 1),
it may be necessary to adjust the number of shims (Ref. No. 12) to ensure
proper running clearance between impeller and casing (Ref. No. 16). Proceed
as follows:
NOTE:
A proper running clearance is less than 0.010”.
1. For impeller replacement, add one (1) shim in addition to those removed
originally.
2. For motor replacement, add two (2) shims in addition to shims removed
during disassembly.
3. Reassemble pump as described in steps 6 and 7. (See INSTALLATION
OF NEW SEAL section.)
IMPORTANT:
Be sure that casing is snugly in place and check shaft to make
sure it is turning freely (use screwdriver slot in the motor to turn shaft). If it turns
freely, check to ensure that adapter (Ref. No. 7) and casing are fitted metal
-to- metal where they meet on outside. If they are not metal-to-metal, tighten
fasteners (Ref. No. 4) and recheck shaft for free turning. Tighten carefully,
turning 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, disassembly pump and remove one (1) shim and repeat
reassembly.
