L3540 leaking at hyd pump

[rodwood]

Does anyone recognise this fittinging?
It developed a small leak quickly getting worse. i believe its the hydrolic Pump main pressure line but?
How difficult if its a seal to replace??
See the round plate at the bottom. Leaks there

It's just an o-ring there and I can see it extruded out. Wondering if the bolts got loose.

Anyway, just pull those 2 bolts out, pull the line a little bit down and pull the o-ring out. Go to an parts store and get a pack of them for a couple of dollars. Then reverse the process.

Get some quality o-ring rated to handle oils though, NBR or Viton. Not that cheap stuff often sold on Amazon that can't handle oils.

Part #070.
