Title: CB400/4 oil pump
Post by: Bloggs on November 07, 2024, 05:53:24 PM
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.

Michael

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.

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.
