How do I Grease This Jack?

The jack on my Anderson utility trailer is getting really difficult to operate. I don't see any grease zerks.

Is there a way to lube this (other than spraying something at the crank)?

Drill a hole and add a zerk. That is what I plan to do to mine.

Re: How do I Grease This Jack?

For my trailer jack (a larger 5K square weld-on drop leg), I used another jack to get the front end of the trailer up, then unbolted the handle, and then the inner part of the jack dropped out of the tube (the part the slides in the outer tube, along with the screw in the center). Then I spun out the screw a bit and greased it, along with greasing the thrust bearing mounted on the top of the screw. Reassembled and it works much smoother. I'm also looking for another bearing for the top, as I found it was completely dry and rusty when I took it apart, so it likely had little or no grease on it to begin with, while the screw itself still was pretty greasy/oily.

Re: How do I Grease This Jack?

If it is anything like mine once you remove the handle you can remove the lower section from the jack. Cleaning and lubing with anti-seize has kept it working smooth ever since.




Social media is a cesspool of questionable human behavior.

Even duct tape can't fix stupid, but it can muffle the sound!

The biggest lie I tell myself is "I don't need to write that down, I'll remember it."

Logic is most useful. If only more humans would learn it and embrace it.

Re: How do I Grease This Jack?

Thanks guys. Found this video, looks like what you're describing:


Interestingly, there are a few comments saying to clean and paint it, but adding grease attracts dirt?

Re: How do I Grease This Jack?

This one is shorter and more to the point. Also talks about bearings (not yet sure if mine has those).

Re: How do I Grease This Jack?

Started surgery on the patient today...

Put a jack stand under the trailer, and removed the jack from the trailer so I could get a better look at things.

As seen in one of the videos, my screw shaft was squared off a bit and wouldn't slide out of the outer tube, so I filed it a bit and it popped right out.

The screw unwound fairly easily, until it hung up at the end (won't come out of the inner tube). Looking up inside, it appears that the screw shaft has a head, and it isn't meant to come out that way, so I'm not forcing it. The jack will probably never be extended far enough to worry about it.

At the top of the screw shaft is a bushing (thick washer), and bearing (a really, really thick washer, not a ball bearing setup).

Picked up new (Grade 8) hardware on the way to my son's Little League game, working on it now while cheering along. Was able to find everything but the bearing, will clean and lube the old one.

Gave everything a quick wire brushing (by hand), will reassemble with anti-sieze and call it good. Don't have time to paint it, just want to see if I can get it functional again before worrying about cosmetics.

Pics of the progress so far...

Mike

Re: How do I Grease This Jack?

It's all back together, I'll get it back onto the trailer tomorrow.

More pics, but I stopped once the lube started and my hands got nasty. In the back of my head, I kept hearing: "Goober it up!"

Anyway, that bearing is a little puzzling. It has an inner recess on one of the flat sides. I didn't notice that when I took it apart, so I have no idea if the recess is meant to face up or down. I left it facing down when I reassembled.

Re: How do I Grease This Jack?

Does the bearing still work as it looks like it's rusted together?

Anyway, I would put the "inner" race down, so it rotates with the shaft going through the bearing.

Re: How do I Grease This Jack?

I don't know what you mean by inner race in this case.

The bearing appears to be a solid piece of steel. It doesn't look like a ball bearing that fused itself together. It was tough to remove, bit wasn't rusted to the bushing.

In the two videos I posted above, my bearing looks more like the first, which the (DIY) guy refers to as a washer. The second (Dutton-Lainson) video shows a ball bearing. I looked at their website, and they do sell a thrust bearing as a replacement part, but I don't know if it will fit my jack.

I haven't tried it under load yet.

Re: How do I Grease This Jack?

OK, it's back on the trailer and working perfectly. Nice and easy to turn and no squeaking!

A thrust bearing (with balls or rollers) would be a nice upgrade, but this should be good for quite a while.

Another improvement would be some flat washers and split washers on the mounting bolts, but that's surely overkill.

Now that I know how easy this is, I'll be less tempted to try spraying lube into the shaft opening on top, which really solves nothing.

I did find a label on the jack, but apparently it was painted or powder coated over when they originally did the whole trailer.
