Dry Sump oil pump failure - anyone seen this before?

[BioBa]

An extensive oil leak cause me to investigate. The problem is a cracked oil pump flange. Looks like I need to purchase a new one. Has anybody seen this before? Anybody has a spare one for sale?

Hi,

I have only ever seen this once previously. It was caused by the pump mounting bolt coming loose, allowing the pump to move and eventually breaking through the weakest point, the o-ring groove.

I would recommend purchasing a new one of these from RPE, as there have been a number of different versions over the years and it is always best to fit the latest item.

Radical Australia have some items being shipped to them over the next couple of weeks, so if you are not in a major hurry order it through them and this will save you on carriage costs.

Let me know if you need any further information.

Nova racing transmissions are the company who make the pumps for radical in the UK and are listed on the nova website. My pump was loose and missing a bolt when stripping for its last re fresh
I have used grade 12 socket head caps crews and loctite when re assembling the engine

Yes I discovered that the thread of one of the bolt holes was stripped.
Thanks for the tip.
