Just been doing some hunting on why my hydraulic steering is notchy and pushes oil out of the steering resevoir.
The UK importers for Lecombe & Schmitt told me it was probbably air in the lines
Was told to remove the ram from the outdrive unit and get it above the helm unit to aid in bleeding also on these helm units (30 HB CAR pump 2200950) there should be an air gap of 15-20mm in the top of the resevoir when the ram is out to compensate for the fact I've got an unballanced ram.
So here's to Dextron II every where as I'm sure to make a mess!
Hope it helps
