Integral Pow Er Steering G Ear - Chevrolet 1980 Light Duty Truck Repair Manual

POWER STEERING GEAR (605 MODEL)
GENERAL DESCRIPTION
This Integral Power Steering Gear has a
control valve which directs oil to either side
of the rack piston. The rack piston converts
hydraulic power into mechanical force. This
force is transmitted to the mating pitman
shaft teeth, through the pitman shaft to the
steering linkage.
This is a small design steering gear. To
determine this gear from our large steering
gear see difference in side cover below.

NOTE: Whenever a part which forms a
sealing surface for an "0 " ring seal is
removed, the "O" ring seal should also be
removed and replaced with a new seal.
Whenever one of the Pitman shaft or stub
shaft seals are removed all adjacent seals
should be removed and replaced with new
seals. Lubricate all new seals with power
steering fluid to ease assembly.
