CRANKSHAFT PULLEY

The original and best one! In STEEL !

ASK ABOUT THE NEW DUAL BELT MODEL FOR AIR CONDITIONING AND BLOWERS

FORD MODEL "A" & "B" (1928-1934)

 

  Steel, one piece, machined from billet, Single Riley Crankshaft Pulley (CP-S). "An exceptionally fine piece of equipment!" High speed design has reduced the diameter to 2-3/4" at the belt groove, which reduces water pump speed approximately 28% for today's higher road speeds. 10/20 degree timing marks as shown. Uses normal length Vee belt or our specially sized slightly shorter belt is available. Finest quality, precision, fully CNC machined and balanced.

There is no noticeable effect when used with an alternator. When used with a generator the 3rd brush can be moved to increase charge.

 

 

                       

  Back in the 1930’s George Riley, the famous race engine designer, discovered that stock Model "A" water pumps would spin too fast for the best rate of cooling, especially at higher engine RPMs, like we experience in today's traffic. So he drew up plans for this pulley and we are pleased to be able to offer this precision speed part to the community. If you drive at modern highway speeds you need this important part.  

 
 
  Additionally, these steel Riley pulleys will not explode or crack like cast iron pulleys can in high speed environments (Be safe, it’s required for hill climbs, racing, over revving). The front oil seal will last much longer with a steel pulley. Cheap aluminum pulleys aren’t good for much before the front crank oil seal will seriously cut into the pulley shank.  

 
 
  Our Riley pulley comes complete with hardened grade 8 bolt and hardened steel washer (CP-BW) to replace the ratchet bolt. Also available separately.  

 
 
   If you want a slightly tighter Vee Belt (CP-V39) we’ve got them too.  Our OPTIONAL 42" Vee belt will take up the combined slack of an alternator and speed pulley.  

 

 
 
 

 

ALSO: We have a Riley Dual Pulley with large and small belt grooves to power an air conditioner conversion. This pulley is a required necessity if you are going to run an air conditioner. The outer 5/8" belt is for the stock Ford belt that runs from the crank to the pump, to generator or alternator.

The small "modern" sized vee groove is to drive the air conditioner pump. Designed by Texans who needed cooling out west through the deserts. We were asked to produce these and have sold them steadily since 2008 with no complaints.

THEY FIT WITHOUT ALTERATIONS
