Due to the length of the shaft on the impeller it may be necessary to remove the water slinger on the motor or shorten the shaft of the impeller in order for the wetend and motor to fit properly together.
Shaft seals for the Vico pumps may be very snug on the impellers, the use of seal lube may be necessary in order to fit seal onto shaft of impeller.
