S&S Cycle Oil Pump for T-Series Engines and Harley-Davidson Twin Cam 88 Engines, Including Standard and Easy Start Camshafts - Manual (Page 8)

Apply a coating of assembly lube to the back of the divider plate and use the two 10-24 x 1⁄2-inch flat head socket screws (60-75 in/lbs) to secure
it. See picture 19, below left. Do not use any threadlock on the screws. Make sure not to apply any weight or pressure on the cams until the cam
cover is installed—do not install the tappets or pushrods until the cam cover case is in place. Screw heads must be flush or below the divider plate
surface. See picture 20, below right.
Before you can install the rear cam drive gear, you MUST install the gear spacer. It slides on the rear camshaft over the keyway. See picture 21,
below left. Install the cam drive gear (timing mark faces out) by sliding a socket larger than the camshaft (typically a 11⁄4" 12-point shallow socket)
over it. Use a 3⁄8-18 x 2-inch bolt with a washer, slide it through the socket drive opening and thread it into the shaft. Tighten the bolt until it presses
the gear on deep enough for it to bottom. See picture 22, below left.
Rotate the rear cam until the cam drive gear timing mark is facing down. Lubricate the idler gear with assembly lube and install it so one of its
timing marks align with the rear cam and the other faces the three o’clock position. See picture 23, below.
