I would guess this is what happened.
That was nice of them to put skids on them, anticipating system failure
Since Douglas hydraulics, with un-pressurized reservoirs and completely overwhelmed right side accumulators (for chriss'sakes even the Brazillia had pressurized reservoirs) a forgetful FO, or normal operation, will result in failure. (Why Douglas, with 69 lighting switches and rheostats on the flight deck could not spring for one micro-switch on the gear handle to run the aux pump, who knows? For that matter, the whole system is a DC9-10's with more reservoir capacity and hooptied up with an old aux pump off a DC-10 to blow the thing up to 3,000 PSID)
Of course line pilots will refer to the QRH and follow that guidance precisely. However, with my Doctorate in Douglas Post Certification Test and Re-Design, ... figure the right side hydraulics were already FUBAR'd and turning everything off could not hurt. After about 3 to 5 minutes for the system to burp itself I'd turn it back on and see what happened. Without the assistance of the DC-10's super hooptie'd super cooled overclocked aux pump to make air bubbles irrelevant at 3,000 PSI the system can get enough air in it to make it less of a hydraulic system and more of a 400 knot Schwinn bicycle tire.
We Douglas Line Flying Test Pilots hope to get pressurized accumulators, or a switch on the gear handle, like Boeing has had since aircraft names had "Strato" in front of them.
