Inspect the pins on the snapper assembly and crankshaft, and the ball
stem, for signs of wear and replace if necessary. The pump will not
operate properly if these are worn. Inspect poppets for damage and
replace if necessary. Whenever the air valve is disassembled, the
O-rings, end plate washer, and gasket should be replaced. Refer to the
Parts section for air valve seal kit part number.
