Now that I have finally had time to test this stupid thing again, I'm convinced that one of these frames is tweaked.
A few things have happened since my last post.
Quickjack sent me new hydraulic fittings made by a company called SABE manufacturing. They don't work with the fitting that came with the unit - they will NOT snap together, no matter what. Now I have a mish-mash of hydraulic fitting that don't want to cooperate, some that work, and some whose center "plungers" stick open, which Quickjack says isn't right. In order to test it today, I replaced a power unit fitting with the original that was sticking open.
They sent the new cam to replace the gouged cam. That worked, and that frame no longer binds while lowering.
They sent a new locking arm to replace the locking arm that skipped out of the channel, on the other frame. Along with the long bolt to mount it. The bolt they sent? It was visibly bent... and much different from the original bolt.
They advised using the original bolt with the new arm. Ok, cool.
They sent a new hose with two fittings... that don't fit the fittings they're supposed to snap into. Because they're SABE.
The new arm has the same problem. It skips out of the channel and want to ride of the frame itself, the cam drops, and won't lock. Even manually lifting the cam, the arm doesn't want to drop into place unless it's forced. This frame is tweaked somehow. It has to be.
Due to my frustration and the issues I've had, they also sent a "gift" -- a complimentary cross-beam adapter. Upon delivery, the box was split open on both ends. And parts were missing...
I'm about done with this thing.
To my surprise, they also sent a JackPack lithium jumper pack/air compressor unit. Wasn't expecting that, but I'm expecting it to blow up the first time it's used.
