S&S Cycle 106 Stroker Hot Set Up Kit For Victory Freedom Engines - Manual (Page 8)

CAMSHAFT CLEARANCING ON EXHAUST ROCKER ARM
1- Front and rear exhaust rocker arms must be clearanced on the bottom side to accommodate the S&S ® .495" cams. Follow Rocker
Arm Removal section of your Victory ® Service Manual to remove exhaust rocker arms.
2- When grinding on the rocker arms it is recommended to cover or tape up hydraulic lifters, oil holes, bearing roller that rides on
the cam lobe, and each end of the rocker arm where shaft runs through to keep debris out of these areas.
3- Remove excess casting material on the bottom side of the rocker arms with a file or belt sander. You should only need to remove
a maximum of .040". See Picture 11.
Failure to clearance exhaust rocker arms will result in intake lobes contacting rocker arms.
Small metal chips and pieces can damage machined surfaces and block passageways. Be sure to thoroughly clean all metal chips
and pieces out to prevent premature failures.
Always wear eye protection while grinding and cleaning surfaces.
4- Once both front and rear exhaust rocker arms are clearanced, wash them clean, and install valve train in motor with S&S .495"
cams. Follow the Camshaft & Rocker Arm Installation procedure in your Victory service manual to install the S&S .495” lift cams.
Rotate the motor in the direction of operation to ensure intake lobes on the cams clear the exhaust rocker arms. Using a feeler
gauge, verify that there is no less than .035” clearance to the tip of the intake lobe. See Picture 12.
5- Finish assemble the engine and install in chassis per Victory service manual. Refer to S&S instruction 51-1204 to install S&S air
cleaner kit 41-0021. These instructions are enclosed in the air cleaner kit packaging. The calibration authorization card is also
enclosed in the S&S air cleaner kit.
