Servicing the Door Lift Assist Assembly

My door lift assist on my '77 NA G model was acting a little hinky, sticking on closing and not fully opening door, and occasionally leaking a little hydraulic fluid. A quick check of the service manual revealed a servicing checklist. As Skymaster jobs go, this one is "easy" and took about an hour to do, start to finish. Lift assist works really well now.
Attached is a PDF servicing guide, for your enjoyment.

Good info LearJetter! The instructions are pretty similar for the 1978-1980 models. Below you will find them, plus another diagram. Interesting that it calls for shop air, not nitrogen, to refill the accumulator.
