Thanks Dave.

They are quite slack, I’ve just changed mine when doing an engine refurb and even the new one isn’t that tight. It’s always surprised me that there is no tensioner considering it runs both oil and water pump. New one costs about £40 so it depends on your budget if you change it.

Hi Gary, can you change the chain while engine in frame? Does the oil pump chain split? Thanks for your help Fry

Hi fry, yes you can change chain with engine in frame. Drain the oil, remove clutch case and clutch and the sprockets are behind the clutch. The chain does not split but the sprocket comes off easily allowing you to fit chain.

Thanks Gary I may do this as the chain seems quite slack with no obvious tensioner.
