CB400/4 oil pump

[Bloggs]

Hi,

As I am stripping the engine to get the cam chain tensioner to work. So one of the first steps, now I have a parts washer, was to strip the oil pump.
The rotor clearances are all well within limits, but the rotor is showing its age (46K miles) and has some scratches / marks. The parts book only shows a complete pump, does anyone know if the rotors ever available separately?
I know they were  / are for the 1000cc Goldwings.

I've never seen them for the 400/4 Michael. We managed to get some for a 750/4 about 5-6 years ago, made by a chap in Italy but he only made them for the 750. I know Honda make them for a few of the newer models. If the pump was working OK, I would use what you have. I had a few scratches on my pump, the roters were within spec, and it worked just fine.

Thanks Bryan. Michael bought parts from me previously, including the oil pump  O ring kit.

My oil pump had about the same mileage as yours when it got pulled out during a wider rebuild and had all it's seals changed ( courtesy Julie) it works fine.
