Assembly
Assemble 011 pump in the reverse order of dts-
assembly, noting the following instructions
Before installing O-rings and oil seal, apply a
thin coat of power steering fluid to them.
Make certain that O-rings and oil
seal are
installed properly.
Discard old O-ring and oil
seal and install new
ones Be careful of
oil seal direction.
