Renault Ares 556rz free flow oil return?

[gav0994]

Anyone able to help on where you would fit a free flow return on the above tractor? Will probably be needing one fitted to run a post knocker fairly soon. I can see a blanking plug to the right of the oil fill plug, but not sure if this would be the right place to fit a free flow to, and what size thread it will be.

Any help much appreciated.

That blanking plug is deceptive, it's a small hole! Official method is T into the return pipe from the valve block on the back end. Unofficial method, drill and tap the filler plug to take a fitting
