COMP Cams ® Special Services
A partial listing of the most common high end
treatments and special processes you can order
for your COMP Cams ® camshaft. Additional services
are available; contact us for any special needs.
Camshaft Surface Preparations
Nitriding - Part #1-111-1
This is the most effective process for extending
the life of a high performance flat tappet camshaft.
Nitriding increases the hardness of the camshaft
surface metal by physically injecting nitrogen “needles”
into the surface of the lobes and journals to
increase their resistance to wear.
Camshaft Micropolishing - Part #1-114-1
This procedure removes microscopic imperfections
in the surface of the metal. Micropolishing
can further increase the durability of the camshaft
and can be performed to just the camshaft lobes
or all wear surfaces.
Xtreme Surface Finish Enhancement -
Part #1-137-1
Our highest-quality finishing process involving considerably
more polishing than any other procedure.
This is most commonly used in steel-on-steel contact
valve train situations, such as high end circle
track flat tappet camshafts where billet materials
have repeated contact in extremely high rpm environments.
Precision Camshaft Measurement
Basic Camshaft Profiling - Part #1-126-1
Performed on two lobes of any camshaft, the component
is measured to determine its lift, duration
and lobe centerline specifications.
Adcole Camshaft Profiling - Part #1-125-1
Our highest precision camshaft measuring device,
the Adcole checks all 16 camshaft lobes to determine
that the cam meets all specifications
requested by the customer. The Adcole measures
camshaft specifications to 0.00001 of an inch.
Special Operations
Replacement of the Camshaft Dowel Pin -
Part #1-120-1
This is a process which repairs camshafts where
the current dowel pin has either been sheared off
or damaged in some manner. The old dowel pin (or
remaining part) is removed by machining and a
new dowel pin is inserted.
Installation of Dual Dowel Pins - Part #1-121-1
For certain applications, dual dowel pins can be
installed to further ensure that the camshaft and
timing gear connection are secure. This is most
commonly done with early model Ford V8’s and
classic Chrysler Hemi engines. We can also
machine the timing gear to adapt to this new configuration.
Drilling and Tapping Camshaft Nose -
Part #1-136-1
A process performed on Viper camshafts, the
nose of the camshaft is drilled and then tapped to
convert from a single timing gear bolt-up to a
three-bolt aftermarket timing chain set. This allows
for a wider selection of timing sets.
Machining a Rear Camshaft Journal Groove -
Part #1-119-1
A process commonly performed on 1965-‘66 Big
Block 396cid Chevrolet engines, which features
oiling systems that require a groove be cut into the
rear journal of the camshaft. This was a two-year
only condition, not required in all 1967 and newer
Big Block Chevrolet engines.
Machining of the Rear Pump Drive - Part #1-116-1
Allows sprint cars-style engines to run the fuel
pump from the rear of the camshaft rather than
traditional placements.
Side Cutting of Camshaft Lobes - Part #1-127-1
A process often requested when the engine’s lifter
bores have been enlarged that helps to keep the
lifters from making contact with adjacent lobes.
Sleeving of the Camshaft Journal - Part #1-132-1
Most popular with Ford Windsor engine roller
bearing camshaft applications, a sleeve is placed
around the standard rear journal to increase the
size of the journal, making it compatible with rear
roller bearing usage.
Fuel Pump Lobe Regrinding - Part #9-999-1
A refinishing process used to clean up a fuel pump
lobe which may have been damaged or is showing
excessive wear.
