Note: Use caution throughout this process to avoid damaging the camshaft lobes, camshaft plate bearings and the gasket surfaces.
CAMS- Standard and Easy Start
The S&S® X-Wedge® is a three-cam design engine. It features a common intake and two separate exhaust cams. The intake cam is located in the
center and has two lobes. The exhaust cams feature one lobe and compression releases. The front exhaust cam has its lobe located closed to
the cam plate (outward). The rear exhaust cam has its lobe located the furthest from the cam plate (inward).
Easy Start Cams
S&S has developed a unique product to assist with starting with a compression release cam. The premise is simple, at cranking RPM, a spring
loaded lever holds the exhaust valve open slightly while the engine turns over, lowering compression. Once the engine fires and RPM exceeds 500
RPM, centrifugal force takes over and sends the lever to a retracted position, allowing the exhaust valve to seat fully.
There is no service required on these cams. If you have the cams out of the bike for any reason, verify that the lever operates smoothly and do a
visual inspection or any debris that may prohibit smooth operation.
Note: With the S&S Easy Start cams in your bike the measured compression will be lower than standard engines. If you have any concerns with cylinder
pressure perform a standard leakdown test.
CAM BEARING REMOVAL
1- Remove the cam bearing seals.
2- To remove the cam bearing use and arbor press and appropriate size tool. Be sure to support the intermediate cam cover evenly to prevent
distortion during the pressing out stage. Be sure that you are pressing the bearings out from the cam chest side of the plate.
3- Inspect the bearing surface of the intermediate cam cover after removal of the bearings. If bores are damaged cam plate replacement is
required.
CAM BEARING INSTALLATION
1- Be sure the bearing surfaces of the intermediate cam cover are clean and free of gouges or scratches. An arbor press is required for this
procedure.
2- Clean all cam bearings to remove rust preventative before installation.
3- Be sure to press from number side of bearing from the cam chest side of the plate.
4- Align bearing to ensure straight installation into bore and press until they are .035” - .045” below the bore surface.
5- Verify the needle bearings rolls smoothly. Apply assembly lube to all bearings and seal surfaces.
6- Install the seals flush with the face of the intermediate cam cover.
