NOTES:

The S&S M8 cam support plate is machined from high strength billet aluminum. This material and manufacturing method provide strength and dimensional stability over aluminum castings. In addition, billet aluminum does not have voids, inclusions and other structural defects associated with aluminum castings.
Variations in color of the anodized finish is not considered a defect. Despite the variations in color, the ability of the anodized coating to protect the part is unchanged. You may install these products with confidence, knowing that they will function as they are intended.
Possible failure may result if thread locking compound is not applied to the cam drive sprocket flange bolts. Always prepare threads according to the instructions on the container.
All reference to Harley-Davidson® part numbers is for identification purposes only. In no way is it implied that any S&S Cycle products are original equipment parts or that they are equivalent to corresponding Harley-Davidson® part numbers.
Installation of the S&S Cycle cam support plate requires the use of special tools and repair manuals for the model of bike you will be working on. Attempting the installation without the proper tools and manuals will be difficult. Damage can result which will not be covered under warranty.
SPECIAL TOOLS REQUIRED (only needed if inner cam bearing will be replaced)
Camshaft Needle Bearing Remover/ Installer, HD® Part Number: 42325-4
Crankshaft/Camshaft Sprocket Locking Tool, HD Part Number 42314 Pre-Cautions:
Clean and flush the oil pan and oil lines to prevent foreign material from being sucked through the oil pump and through the new cam support plate. The oil filter should also be changed when installation is complete.
NOTE: If debris is suspected in the oil pan, It is highly recommended to remove the oil pan in order to thoroughly clean it out.

Installation

Unpackaged the cam support plate kit and verify the all the threaded plugs have been installed. Confirm that the kit contains a new o-ring kit and hydraulic tensioner block off plate kit.
Prepare the cam support plate for assembly by cleaning the plate with soap and water or parts cleaner. Be sure to thoroughly dry the internal passages.
Before starting work on the motorcycle, disconnect the negative terminal of the battery to eliminate the potential for sparks and inadvertent engagement of the starter while working on the motorcycle.
Refer to the HD® service manual for the model of bike you will be working on for proper removal of all components. Save the original fasteners to be reused when the the S&S cam support plate is installed.
Remove the cam support plate and oil pump from the engine according to the HD® service manual and measure flywheel pinion shaft run out. Refer to the manual for proper procedure. S&S recommends no more than 0.005” of total indicated runout on the pinion shaft while checked in the cases.
If you intend to reuse the existing oil pump, it must be thoroughly cleaned and inspected to ensure that it is serviceable. Refer to the manufacturer service wear limits for the gears and pump body bores. If the areas under the pump gears are scored this will adversely affect the ability of the pump to supply and/or return oil.
Inspect the inner cam bearing, now is the time to replace this bearing while the engine is apart. It is highly recommended to replace the bearing with a full complement bearing, S&S Cycle pn 31-4199-S. Refer to the service manual for proper procedure to replace this bearing. B
- NOTE: Use as much of the provided assembly lube as possible on all of the oil pump rotors during assembly. This will aid in priming the oil pump upon start up.
Install a new o-ring on the flywheel cavity suction side of the oil pump and re-install the pump into the cam chest. Use a straight edge to confirm that the outer face of the oil pump is recessed slightly from the cam plate mounting surface. (See Picture 1). This is done to ensure that there will be no binding in the oil pump when it is tightened to the cam plate.
Install a new o-ring into the oil supply port of the engine case. See Picture 2.
Apply assembly lube to the rollers of the inner cam bearing and to the cam bearing surface and lobes of the camshaft. Insert the camshaft into the inner cam bearing.
Apply assembly lube to the outer cam bearing surface of the camshaft and to the pinion shaft.
Install the cam support plate onto the pinion shaft and camshaft. Make sure the support plate fully contacts the mounting surfaces of the engine case and the dowel is engaged into the mounting hole.
- NOTE: The oil supply passage o-ring will hold the plate slightly off the mounting surface until the support plates screws are fully tightened.
Turn the crankshaft so that the flat on the pinion shaft is facing straight up (12 o’clock position).
Apply a small amount of blue threadlocker to the cam support screws and the new oil pump screws. Make sure the flat washers are installed on the oil pump screws.
Steps 16 thru 22 are critical to proper final assembly.
Make sure the flat on the pinion shaft is facing straight up. See Picture 3 for correct orientation of pinion shaft.
Loosely install all cam support plate and oil pump screws but do not apply any torque.
Snug the oil pump screws A, B, C and D but do not torque.
Snug the cam support plate screws 1, 2, 3, 4, 5, and 6 but do not torque.
Torque screws 1, 2, 3, 4, 5, and 6 in order to 90-120 in*lbs. See picture 3a.
Rotate the crankshaft two complete revolutions with the flat on the pinion shaft facing straight up (12 o’clock position) when done.
Torque the oil pump screws A, B, C, and D in that order to 90-120 in*lbs.
Rotate the crankshaft to make sure binding does not occur in the oil pump. If binding occurs, loosen the oil pump and cam support plate screws and go through the installation procedure starting at step 17.
Install the cam drive components (chain or gear) according to the manufacturer’s installation procedures.
Apply blue thread locker to the cam cover screws, and install the cam cover, gasket, and screws. Tighten the cam cover screws to 120 in-lbs in the sequence shown
(See Picture 4).
Reinstall the pushrods according to the manufacturer’s installation procedure.
Reinstall the exhaust system and right side floorboard or foot peg.
