S&S Cycle Oil Pump for T-Series Engines and Harley-Davidson Twin Cam 88 Engines, Including Standard and Easy Start Camshafts - Manual (Page 5)

On either stock or S&S® cases, verify that locating dowels have not been pushed in all the way. See picture 4, below left. If they have, you will need
to thread an appropriate sized screw into it and pull the dowel out to measure .100" -.125". Once the dowel is at the proper depth, thread the S&S
thread adapter into it. See picture 5, below right. Note that the thread adapter needs blue 243 Loctite® and you MUST NOT use a lot of pressure
when installing. Just a bit more than hand tight is all that is required.
Unpack the S&S reed valve and spring. Install the reed valve over the pinion shaft ensuring that the O-ring is seated fully in the case - there is no
specific orientation to worry about. See picture 6, below left. Next, simply slide the spring into the machined groove on the reed valve and allow it
to rest on the pinion shaft. See picture 7, below right.
NOTE: Engines built with S&S SA cases will require the installation of a spring adapter PN 31-2103 to support the spring. The large end of the adapter goes
into the breather as shown in Picture 6a center below.
Open the O-ring pack included with the kit and install them around the S&S case perimeter. Harley-Davidson® cases will require only 3 O-rings (early
1999 H-D® uses only 2). Be sure not to forget the large O-ring pointed out in the Picture 8 below.
