Mazda Rotary Underdriven Multi Rib Pulley Kit – Electric Waterpump

NO waterpump pulley or belt.
Designed and manufactured in-house using aircraft grade 6061 aluminium billet.
5PK belts have significantly more grip and less frictional loss than a Vee belt. Suitable for engines running an electric waterpump.
Two versions available:
Bolt on crank pulley (suitable for all idle speeds)
RACE one piece crank hub/pulley (suitable for idle speeds above 1600rpm)
No risk of thrown belts, as with single and double Vee pulleys. -Lightest kit available.
Machined to tight tolerances eliminating runout and wobble. -Alternator pulley fits all 15mm and 17mm shaft alternators (12A thru FD) by means of a removable sleeve (included).
35 micron semi hard black anodised for surface toughness and longevity.
55 micron hard anodised RACE one piece crank hub/pulley (crucial for preventing the front main seal cutting into the pulley).
TDC mark etched into RACE crank pulley.
