Oil in Belly

[JAG]

Gents,
Had a similar event with oil on the floor, last month. It had been a few days after flying, there was a small puddle (2" diameter) on my hangar floor. (NOTE: I have resealed all my actuators, hand pump and replaced all flexible hydraulic hoses last year.)Oil had come out of drain holes in front of, and aft of, the handpump. I pulled up center floor board to note that the whole area was wet, and could not quite trace it to anything. started going upstream, and noticed it may be coming from pilot side forward. Looking at brakes, brake lines, etc, and did not see anything. Looked at power pack and did not notice anything major, but one line and a little fluid on it (not good). Looked in little drip tray under power pack, and there was a bit of fluid. Ran some mineral spirits down that tray drain tube, and voila - that confirmed the source. That drain tube does not drain overboard, but rather into your belly underneath the pilot's rudder pedals.
I ended up removing and overhauling my power pack - there was a hairline crack on the manifold at the "gear down" fitting.

Thanks for the advice and suggestions! We will investigate further and I’ll report back to the group.

Well, it’s the main gear actuator. Any suggestions on sources for overhaul or replacement?
