Port covers and access plugs for the GP5142 — the crankshaft end cover, its retaining screws, and the three port plugs: upper discharge (1" NPT), lower suction (1-1/2" NPT), and auxiliary (1/4" NPT). These parts are needed when a port shows thread damage, plugs are lost during service, or the crankshaft end cover is removed for shaft access.

Low cost and straightforward, but missing port plugs will cause immediate pressure loss and fluid contamination. These share the same part numbers as the GP5132 end cover components. Keep at least one spare set on hand for field service kits.
