I think there are stickers on mine. You likely have 4600 like I do. I think those are the only model with quick release levers.
My 2002 4100's have a quick release lever.

IMHO, I am not a fan of WD40 for other than applying to unimportant places, i.e. lawn mower wheel axles... or, better yet, for coating bass lures (great for catching fish!). I carry a couple cans in the boat all the time. I wouldn't use it on a HJ, the stuff has a tendency to gum up after a while and, frankly, I don't think it has all that good lubrication properties. If you want to use a light weight oil, I'd recommend something like TriFlow or Lubriplate spray oils. WD40 does work great as a lubricant when machining aluminum.

Stevenal,
I used a 3 or 4" piece of R45 welding rod - may be a bit stiffer than a coat hanger. Don't put much of a hook on it - mine is just a straight 90 deg bend and is not very long - it fits between the vertical shaft and the bevel gear. I also put another hook at the top end and either grip it with a folded rag or a pair of needlenose. Popped all 4 off at least once easy as pie. And be careful where you do it, because they can go flying.

Have you tried holding constant pressure up on the hanger hook then tapping down on the shaft? Otherwise find something a little stiffer like bucket handle maybe?

These jacks are so well lubricated that the extension would start to extend on it's own from gravity when the quick release lever was activated.
IMHO, that's the way they should work.
Don't assume too much from the way it moves. Only one of my four jacks moves that easily right now. It's the only original one (now almost 4 years old). The other three I sent back to Happijac when they were 2 years old for a paint issue and they retubed them (free re-build for me ![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/smile.gif "smile") ). When they came back they move much harder manually. My theory is there is more grease in the rebuilt ones than the original one. I'd be willing to bet the used jacks you got will need refreshing sooner than you think.
A couple of years ago my brother rebuilt his and had the same thing happen. More grease meant harder to move when released. I don't think that's a bad thing.

MTBob,
I took apart the clutch in the motor that was popping and could see that it had indeed been recently slipping. Mine is a bit different than yours. It has 6 ball bearings that are smaller than yours. Also, I tested the torque on the clutch nut of a different motor and it looked to be about 30 - 35 inch-pounds, so that's what I set the one I took apart to.
