LC Pro Distributor
-----------------------------------------------------------------------
The 4 Main Causes of Premature Camshaft Failure
 

  
 
   
  LC Pro Distributor
   
 

An often forgotten component, but extremely important one for performance!

The distributor handles several jobs.  It’s first job is to distribute the high voltage from the coil to the correct cylinder.  This is done by the cap and rotor.  The coil is connected to the rotor, which spins inside the cap.  The rotor spins past a series of contacts, one contact per cylinder.  As the tip of the rotor passes each contact, a high-voltage pulse comes from the coil.  The pulse arcs across the small gap between the rotor and the contact (they don’t actually touch) and then continues down the spark plug wire to the spark plug on the appropriate cylinder.

When you do a tune-up, one of the things you replace on your engine is the cap (Part#17-901) and rotor (Part#17-902) – these eventually wear out because of arcing.  Also, the spark-plug wires (Part#17-104 or#17-103) eventually wear out and lose some of their electrical insulation.

  Spark timing is so critical to an engine’s performance, and the timing can either be advanced or retarded

depending on conditions.  The time that the fuel takes to burn is roughly constant.  But the speed of the pistons increases as the engine speed increases.  This means that the faster the engine goes, the earlier the spark has to occur.  This is called spark advance: the faster the engine speed, the more advance is required typically.
 
LC Engineering Pro Distributor’s (Part#17-100 & #17-100V) provide an increase in horsepower and acceleration do to a performance ignition curve.  However, in order to achieve top performance, it is imperative that the installation and timing be set correctly.  The Pro Distributors are set with a 20° @ 2000 rpm curve.  The best way to time these units is to find TDC on the #1 piston and install the distributor at 10° initial timing.  You will then have 30° to 32° total degrees of timing @ 2000 rpm’s.  Street engines with lower compression ratios can increase total timing between 36° and 38°, beware of pre-detonation!
Inside the LC Pro Distributor
 
   
  Some users will like to advance or retard timing, as each motor is different (i.e. compression ratio, head milling, etc…).  Please call our Technical Department for specific applications at 928-505-2501.
 
The 4 Main Causes of Premature Camshaft Failure
   

The key parts of any camshaft are the lobes.  As the camshaft spins, the lobes open and close the intake and exhaust valves in time with the motion of the piston.  It turns out there is a direct relationship between the shape of the cam lobes and the way the engine performs in different speed ranges. 

It is highly recommended that you change the rocker arms with every cam change and keep them together as a package or kit.  The reason is, rocker arms burnish themselves to each cam lobe.  As we know, each cam is ground on a different angle and each rocker arm wears at a different angle.  If you use rocker arms from one camshaft to another, they will most likely trough into the new cam lobes.
   
Here are the four most common causes of premature camshaft failure:
 
  1. Improper break in procedure.  Excessive or long cranking on initial start up.  Engine must start immediately and run at 1600-1800 rpm’s for 20-30 minutes
  2. Improper rocker geometry, changed by: increased camshaft lobe lift, valve tip height and rocker stand height.
  3. Improper valve springs.  Inadequate clearance between coils (coil bind), spring pressure too high or spring pressure too light.
  4. Reground camshafts with reduced base circle diameters will cause premature
    lobe and rocker wear.
   
 
Rocker Arm Burnish   Camshaft Burnish
   

Note:  To correct rocker arm contact pattern, mark the rocker arm with a black ink marker, rotate engine two (2) complete revolutions, inspect contact pattern.  If ink is wiped off nose or heel of rocker arm, you will need to adjust the rocker shaft stands. 

Usually milling the stands .015” / .020” will center the pattern.

Always check valve to piston clearance.  The minimum clearance should be .100”, if using an adjustable cam gear, check with full advance and retard to assure adequate clearance.
