Samson PM4 3:1 Lower End / Pump Piston Repair Kit #734965
Genuine Samson lower-end pump piston repair kit for PumpMaster 4 3:1 pump #340120. Samson lists #734965 as a PM4 3:1 lower-end kit, while the PM4 technical documentation identifies it more specifically as the pump piston or intermediate-valve repair kit.
The kit services internal components in the lower pumping section rather than the pneumatic air motor. It should be selected by both the repair-kit number and pump model because Samson specifically associates this configuration with PM4 #340120.
