S&S Cycle 106 Stroker Hot Set Up Kit For Victory Freedom Engines - Manual (Page 7)

3- Observing previous warning, check for a minimum of .050” travel to coil bind as follows:
A- Place spring in a vise with soft jaws or spring checking device and carefully compress to coil bind and record spring height.
B- Determine distance to coil bind by subtracting coil bind height from installed height. If coil bind was .990”, for example, and
installed height is 1.550, then 1.550”- .990” yields .560” travel to coil bind. Subtracting .050” from the .560” travel will allow
a .510” lift cam to be installed with acceptable clearance to coil bind.
C- Repeat procedure for each spring assembly.
4- Install valves and valve springs in heads. Be sure valve guide seals are in place. Install all S&S beehive springs with smaller OD toward
top collar. Install each spring followed by top collar and keepers.
NOTE: Installed height should be the same for each spring assembly.
5- Confirm valve spring to rocker support clearance.
A- Mock install rocker supports without cam or rocker arms. Note that valve spring-to-rocker support clearancing will be required
in four locations . Clearance can be checked using feeler gauges or lead solder. Minimum spring to rocker support clearance
to be .060”. See Picture 10.
Small metal chips and pieces can damage machined surfaces and block passageways. Thoroughly clean all metal chips and
pieces from components.
Always wear eye protection while grinding and cleaning surfaces.
B- Determine and mark each location for clearance operation with a permanent marker, remove the rocker support and perform
clearance operation with a die grinder.
C- Recheck spring to rocker support clearance to achieve a minimum of .060” clearance. Repeat step B if necessary.
NOTE: Remove minimum amount of material needed to obtain .060" clearance. Care must be taken not to break through rocker
supports or affect heat treatment by overheating while grinding. Oil is supplied to Victory
® top end through rocker support, so it is also
important not to disturb oil passages.
6- Assemble heads to engine according to Cylinder Head and Valvetrain section of appropriate Victory service manual. Do not install
camshafts at this time.
