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 |
