Replaced the lift pins and the reverse switch. Cleaned and oiled. Goes up great. but wont go down.

Is that cross pin in the wrong place?

Is the top lift pin in there upside down ..... I don't think they are drilled on center for the roll pins if I remember right .... but its been a while since I have had one apart and my memory may be a bit foggy on that.

the pins have a bevel on them. the bevel faces up and goes in the holes on the stand. the roll pins are in the same way yours . your picture the switch is in the raise position my picture its in the lower position

It requires a load to work right. When the handle is jacked, the head goes up a bit before it lowers again.

Big Bob tried that too. Put it under the receiver hitch on my jeep. Took it up 5-4 holes. No luck

That's what I remember also.

Turn it off and back on.

I have had some that were contrary and you would have to tap it with a hammer to get the pin to release when trying to lower it. Mostly because they were gummed up, that doesn’t seem to be an issue with yours. Never seen jacks as clean as the two pictured.

That one pin looks crooked is the only difference I can see.

Its supposed to ride up that bevel a bit law dog when the switch is in the down position. I think. It goes horizontal when when you flip it to jack up. I cant figure out how it works so well going up but wont reverse.

My pin does not tilt in either position it stays horizontal snapping the lever in and out. Looks like the bracket slopes down towards that pin like a wedge shaped drop to where the pins in place.

When I lower the switch to lower the jack that wedge moves down against the roll pin. When you pop it up to raise the jack it returns the roll pin to horizontal


raise position


lower position.

Well i figured it out after thinking about what you said Law dog. I did not have that roll pin pushed through far enough. instead of pushing the lift pin up it just turned it.

Thanks for the help

Anytime

This works. I was pretty sure it was something simple

Interesting thread to follow!

oil

Well I was going to tell you what the problem was, but you figured it out before I got to the end of the thread. lol! Mine is always gummed up from riding around strapped to the side of the flatbed, so I often have to reach and grab the lift pin and hold it out for it to slide down freely.

As I remember the instructions, You can't get away with reversing the jack by HAND, you need to smack the reverse lever with the jack handle.
