Connecting Rod Code Location
Numbers have been stamped on the side of each con-
necting rod as a code for the size of the big end. Use
lhem, and the letters stamped on the crankshaft (codes
for rod journal size), to choose the correct bearings.
lf the codes are indeciDherable because of an accumula-
tion of dirt and dust, do not scrub them with a wire
brush or scraper. Clean them only with solvent or deter-
gent.

Selection
Each rod falls into one of four tolerance ranges (from 0
to + 0.024 mm {0 to + 0.0009 in). in 0.006 mm (0.0002 in)
increments) depending on the size of its big end bore.
lt's then stamped with a number 1.1.2,3, or 4) indicating
the range.
You may find any combination ot 1,2,3, or 4 in any
engrne.

25. Coat the piston seal ring guide with power steering
fluid, then slide it onto the rack, big end first.
26. Position the new O-ring and new piston seal ring on
the sDecial tool, then slide them down toward the
big end of the tool.
Note these items during reassembly:
a Do not over expand the resin seal rings. Install
the resin seal rings with care so as not to dam-
age them. After installation, be sure to contract
the seal ring using the special tool (sizing tool).
a Replace the piston's O-ring and seal ring as a set.
27. Pull rhe O-ring off into the piston groove, then pull
the piston seal ring off into the piston groove on top
of the O-ring.
Coat the piston seal ring and the inside of the spe-
cial tool with power steering fluid.

Carefully slide the tool onto the rack and over thepiston seal ring.
Move the special tool back and fonh several times
to make the piston seal ring fit snugly in the piston.

31. Wrap vinyl tape around the rack teeth and rack end
edges, then coat the surface of the tape with the
power steering fluid. Make sure that the vinyl tape
is wrapped carefully so that there is no stepped por-
tion.
Coat the inside surface of the new cvlinder end
with power steering fluid.
Install the cylinder end seal onto the steering rack
with its grooved side toward the piston. When
installing the cylinder end seal, be careful not dam-
age the sealing lip face of the seal with the edges or
teeth of the steering rack.
CYLINDER END SEAL
Make sure thespring is in lhe cylindereno seal
Remove the vinyl tape from the steering rack, then
remove any residue from the tape adhesive.
