Onan 120-0491 Oil Pump Internal Rebuild Kit CCK B, P & N Series

Arrived in a timely manner. Gears and gaskets are in sealed Onan packaging so not aftermarket or fake. My pump gears looked OK but showed signs of some wear and the machine shop suggested I replace them. Doing a full rebuild on a CCKA that powers my Lincoln welder. Not taking any shortcuts since I need a good portable machine on the farm for repairs.
