Honda CB750 Oil Pump Rebuild Kit CNC ROTORS

(3 customer reviews)


Honda CB750 Oil Pump Rebuild Kit CNC ROTORS for FOUR SOHC 1969-1978.

This will get your oil pump to better then OEM new state and for less then what OEM rotors would cost if they were ever available.


  • CNC machined from billet 4732 steel. This steel has 30 RC of hardness(original sintered rotors have 10RC of hardness).
  • This set of CNC oil pump rotors will outlast OEM rotors because of three-time more hardness(30RC) of 4732 steel compared to OEM rotors material.
  • Tolerance between rotor tips is 0.1mm or less. Better than original OEM oil pump rotors!

    My new race engine for goodwood in 2 weeks has your rotors inside it, It is in a race against guy martin, so a proper test !!!!!

    …my race bike has too much oil pressure now, your rotors are good

  3. Per, Sweden

    The rotors have a fantastic tight fit without any metal contact when rotating the sprocket as old Honda due to scuff marks that also sat looser in the pump body.

    I have one more pump that will get a set of these nice rotors. Both my bikes will get a pump swap, upgrade of pressure when oil is hot.
