EXHAUST VALVE BODY ASSEMBLY: Early Models of 130-137 had a pin type Valve System that should be replaced with
system shown on Page 11.2. Inspect gaskets and metal seats for damaged surfaces, replace when necessary. Parts must be
clean prior to assembling.
NOTE: When installing Exhaust Valve Assembly into Tube, spread Tube slightly as "0" Ring (130-55) passes front sight pin
holes. Damage to "0" ring seal will cause air to by pass valve.
Pump Assembly: Early models of 130-137 had an "0" Ring piston. This type piston should be replaced with one shown in
Drawing Page 9.4.
All steel Pump Lever (130-8) replaces Lever with wooden forearm.
When assembling Pump Assembly to Tube adjust Piston for maximum stroke before tightening Pump Lock
(101-19). Maximum stroke is obtained when Pump is in closed position and Front Sight Pin holes lined up. Use Pump
Adjusting Pin tool (T-2) for this purpose.
Some models contained a headless Breech Bolt Screw that should be replaced with (140-52) to prevent loading sleeve from
lifting up.
