INTRODUCTION

S&S

rocker arm rebuild kit will rebuild a complete set of

S&S rocker arms for 1984-up big twin and 1986-up
Harley-Davidson

Sportster

models.

The bushings in this kit also fit stock Harley-Davidson

rocker arms, but they are not a direct replacement for
stock bushings. S&S rocker arm bushings are wider
than stock.

KIT CONTENTS:

●

8 Bushings

●

4 Rollers

●

4 Pins

●

10 Retaining Clips (Two extra clips included.)

INSTALLATION

A. Remove, install and machine bushings

NOTE: Rocker arm service tools, including bushing
pullers and installers, are available from specialty tool
suppliers. They should be used according to the
manufacturers instructions.

NOTE: The instructions S&S provides are for the
experienced mechanic with access to an arbor press and
bench vise for the removal and installation operations.

Important: Read before bushing removal.

●

Bushings must be finish machined after installation.
The method used to finish size the rocker arm ID
determines the order of disassembly/assembly.

●

If using a line hone to finish size the bushings,
remove and install bushings on both sides of rocker
(per bushing removal and installation instructions
below) then finish machine both bushings at the
same time using the appropriate sized hone.

●

If using a reamer (H-D

#94804-57 or equivalent) to

finish size the bushings, remove and install bushing
on one side only (per bushing removal and
installation instructions below,) then ream to size
using the bushing on the other end to align the
reamer.

NOTE: Some aftermarket reamers allow both new
bushings to be reamed at the same time. If using an
aftermarket reamer, follow manufacturer’s
instructions.

NOTE: All reference to Harley-Davidson part numbers is
for identification purposes only. We in no way are
implying that any of S&S

Cycle’s products are original

equipment parts or that they are equivalent to the
corresponding Harley-Davidson

part number shown.

Bushing removal.

Remove old bushing using an arbor press.
Turn a

⁄

-18 tap into the bushing. Press out

the bushing and tap from opposite side of
rocker arm. See Picture 1.

2. Bushing installation and machining.

NOTE: use assembly lube on bushing and rocker arm
bore during the press procedure.

One end of each bushing has a lead-in
chamfer.

Position new bushing with

chamfered end to bore of rocker arm. Align
rocker arm and bushing in arbor press, then
press in the bushing so the outside edge of
the bushing is .005"-.015" recessed into the
end of the rocker arm. A socket with a
slightly smaller O.D. than the bushing will
work as a driver. See Picture 2.
