WALKER EVANS™ SHOCK REBUILD
INFORMATION
When performing maintenance on Walker Evans™
shocks, use the Gas Shock Recharging Kit (PN
2200421), as it contains the necessary valves, pressure
gauge, and fittings to deflate and pressurize shocks.
Walker Evans™ shocks contain high pressure nitrogen
gas. Extreme caution must be used while handling and
working with Walker Evans™ shocks and related high
pressure service equipment. The pressure must be
released from the shock before disassembly. It is
strongly recommended you wear safety glasses and
ear protection during these procedures.
