Jabsco part # 92700-0520

The Jabsco 92700-0520 is a seal for a Jabsco rubber impeller pump. MECHANICAL SEAL REPLACEMENT
TO REPLACE SEAL ASSEMBLY : Loosen adaptor clamp nut and remove pump head from motor Use a screwdriver to spread the clamp slighty to facilitate removal. Remove end cover cap screws, end cover, gasket and wearplate. Remove body, gasket and wearplate from adaptor. Push impeller from body bore. Remove seal liner and seal by pressing from motor end of adaptor. Remove seal from liner. Check all parts for wear. Replace if questionable. Install seal liner in bore of adaptor, aligning bolt holes carefully. Dip seal in water for lubrication and push into seal liner bore with lip facing outwards. Wipe a thin film of grease on lip of seal. Install wearplate against liner, install gasket, align bolt holes. Push the impeller into the body and rotate the impeller in a clockwise direction to align blades for correct direction of rotation. Place the body impeller assembly over the gasket and wearplate, and carefully insert the impeller extended insert through the seal. Install the four capscrews through the adaptor flange and screw into threaded holes in body flange. Tighten bolts evenly and securely. Replace wearplate, gasket, end cover and secure with end cover cap screws. Align the tab in the slinger bore with the keyway in the shaft and push the slinger part way onto the shaft. Align the detent in the impeller extended insert with the keyway in the shaft and push the pump head onto the motor hub, firmly against the motor. Tighten the adaptor clamp nut just enough to prevent the pump head from turning on the motor hub. If too tight, motor bearing will seize the shaft and become damaged during operation. Attach short lengths of hose to suction and discharge ports and place both hose ends in a bucket of water, before plugging motor in, to check operation.
