Hein-Werner Jack Wheel Question

[Junkman]

I picked up a 1 1/4 ton Hein-Werner jack this weekend at a swap meet, and this one has a good cylinder in it. That is where the good news ends. The wheels are severely worn, and I have pulled them off, in anticipation of installing new ball bearings. In order to get them off, I had to first remove the wire retaining ring that goes around the end of the axle. What is the proper term for this "ring or clip", and where can I purchase them?
The next question concerns the wheels. The hole where the axle goes through is extremely worn, and I was thinking of drilling it out to 9/16", and installing a 9/16" x 7/16" x 1 1/4" hard bronze bushing. Do you think that this will work out satisfactory? My thoughts are to turn the axles over, so the bushing will be riding on an original surface, and the worn surface will be on the top.

Have you tried PMing Hiball yet? He seems to be the know it all on jacks around here........

Fairly common for the Wheels/Axle shaft to wear on these models, More so when they didn't receive any lube via the zerk as I don't think they utilized bearings. I believe the Ring you are referencing is a style of Circlip similar to the picture below. Note: HW used those clips on just about all there models from that era, there are more current clips that can be used as replacements if you clean up the edge a bit.



IMO the only way to really fix your jack "Based" off your description is to resize/bushing or Make a New shaft, which would require some Modification to the Front Axle or the Swivel Caster axle as you never really specified what end we are dealing with, but regardless the process would be similar. If you do decide to go with Bushings, I would drill a Grease hole to allow "some" lube to make its way to the shaft.

Thanks for your input. It is my intention to have the original holes bored out to allow a press fit of the hard bronze bushing, and drill a hole in the bushing to allow grease to get to the axle. Since replacement axles are not available, and I can't find anyone that will knurl the ends like the originals, I decided that turning them over so the pressure will be on the surface that was originally at the top of the axle, is the next best thing. I will be doing the same thing with the front wheels, turning the axle, and bushing the wheels themselves. This jack appears to have lead a hard life, however, I believe that the hydraulics were rebuilt, since there is what appears to be an invoice number stamped into the jack near the handle.

Moving it around without wheels is a real drag....

Should have the casters used/maybe new. the little clips are all over. Voris hyd Springfield Mo 417-869-7933

Very similar to my Model F, with some of the same challenges.

1. Replacing the caster axles was easier than bushing the wheels. I just got a length of 9/16" steel rod, reamed the caster wheels and mounting ears to fit, cut to length, cut grooves for the circlips, drilled for a zerk, done and done.

2. The bearings for the entire caster pivot were more work. I bought a bag of 100 loose1/4" ball bearings. There were semi-circles where the leverage of the offset caster had worn deeper. I ground them flat, cleaned up the top half where the retaining groove is, used heavy boat trailer waterproof grease and reassembled.

My hydraulics are leaking, so the next step is to rebuild the pump and cylinder.
