Well after some research I found that my engine mounts had all failed!! So the engine was not bolted down!! I've now replaced these with new ones, and started engine again and it's still the same making a strange grinding noise, it's not the wear ring that looks good.
So I've dropped the pump off and removed the drive shaft and the engine ran ok, so problem is drive related, the pto bearing came out with the drive shaft could this be my problem???
The impeller seems to rotate freely in the pump and seems to have no excess play so I don't think the bearings are shot in the pump.
Could the drive shaft being slightly bent cause the noise? It sounds like something is binding and putting a load on the engine
Please help
