rhasler Posted March 31, 2011 Share Posted March 31, 2011 You'll need to remove it from the engine first, remove the end caps, then push the core out. I usually place a wood block under the end without the flange, set the assembly vertically and bump it against the ground so that the core is pushed upwards. You can build a couple of plates and gaskets to bolt onto the oil inlet and outlet ports on top of the housing, one blank, and one with a tapped hole, so that you can pressurize the assembly to check for leaks.

This is an index mark, it should be pointing up. Quote "Mebbe I'm too ugly and stupid to give up!"
