We are happy to announce a new sponsor to our boardtrack
cross over bike. Not only do we have Bikernet.com as a main
sponsor, but we have added Custom Cycle Engineering as a
In this tech tip, we will show an install of CCE's finned
Panhead rocker covers. We dig these covers. Designed by
Randy Smith during the "chopper period" these covers are highly
sought after in the bobber community and we are jazzed to put
them on our project.
Our project encompasses installing rockers and covers to a
set of STD heads with a custom configuration.
Laying out all of your parts on a clean bench will allow for a
clean, easy job! Everything looks like it’s there........
We started with a custom set of STD Panheads, which were
set up with Shovelhead valves (breathe better), normal Pan
exhaust spigots which fit our Boardtracker frames, and
Shovelhead intake ports which also flow better, and finally
outside oilers which add a small cooling effect for oil delivery.
First off, spray your rocker studs off with a good quality
"Anti Seize" lubricant. Notice the "Made in U.S.A." on the can!
Make sure you support your fellow American worker- it will cost
you an extra 10 cents, but you will help curb the time frame
between now and the inevitable. Either that, or bone up on your
Mandarin dialect. Let’s try to keep at least 51% of our dollars
here in the states folks!!!
I love the U.S.A. and there are far too many
dialects in China for me to learn in a short time. Enough said.
Install studs until the final thread on one side is
visible. With the anti seize compound they should thread in by
hand. If not, check your threads and make sure they are clean!
Install rocker blocks making sure to seat the block assembly
all the way down onto the head deck and fasten with locking
nuts. I oil the rocker shafts so they don’t start dry.
1) Notice the necessary intake oiler port (two of these are
needed; one on each intake side), this assures oiling of the valve
assemblies on the crown of the motor (high point).
picture shows an example of the necessity to bring the intake
studs up about a thread to make sure the lock nut gets full bite.
Note- stock oilers are thinner gauge and may not need the
Finish tightening. Always use a crossing and alternating
pattern when drawing precision surfaces together. Tighten in
small increments while crossing your pattern in exact opposite
relations, when you bottom-- you will know it without question.
Rocker assemblies installed, make sure to check all rockers
for tolerances. Some lash fore and aft is acceptable and
necessary, however no "shake" should be exhibited. The rockers
should move freely and not feel "bound" in any way.
Normally, I would run a felt gasket under the "Pans". These
were used to deaden the valve train noise on the early Panheads.
Since these covers are cast and incredibly thick, I have a hard
time anticipating any "tinny" resonance coming from the valve
train! No gasket employed. Always check for rocker clearance
under the "Pans" before installing. The CCE rocker covers had
Place new gaskets under your rocker covers between the
cover and head. Remember to cross and alternate your bolt
tightening patterns to assure even placement and alignment of
your machined surfaces. Be patient and continue to tighten
slowly and evenly around all bolts alternating front, back, side to
side in symmetrical opposites. You might use anti-seize on the
Allen treads to prevent any damage to those delicate aluminum
Pan threads. Make ‘em last. Don’t over-tighten!
Wow, everything lined up perfectly and the covers came
down perfect on the heads without the hint of binding in any of
They tightened and bottomed
Some use thread lock on these. I
have never needed thread lock on any of this stuff and we come
from the old paper gasket machines. When you put two
machined surfaces together (even with thin paper gaskets that
you wet and swell before installing), if you mate the surfaces and
draw your bolts properly, you will notice no failures of the seal.
When you tighten areas that heat and cool (like a motor &
tranny), make sure during the first heat and cool periods that
you re-torque all bolts to spec. Once this is done the bolts seat
fine and stay there! No need for thread locking this stuff!
We will follow up with a top-end install shortly. We are
placing these pretty girls on top of a ‘57 FL case set.
