Hiball: a quick status on the HF 1-1/2 ton rapid pump jack. I removed the ram and reservoir, but I was not able to remove the cylinder, I was hesitant to push too hard on the pipe wrench over fears of warping it. I think I will leave it as is. The inside of the cylinder looks good to me. I...

yep, each drive pump had a copper washer (held on by the cylinder), and a 0.195" dia ball below the copper washer. Also another hole or channel in each of these. There were no observed issues with any of the pump piston parts. No worries Hiball, appreciate all the comments so far. As I...

yep, the internal screw, not the cap. I have had the caps out since the start (surprisingly no o-rings on those). Thanks.

ahh, I was thinking the 2 valves were both safety valves, I forgot about the rapid pump function, and that valve is not safety, but part of the rapid functionality. I understand better now. Some of my earlier statements are inaccurate. Thanks much. So any ideas why the rapid pump valve ball...

I have both safety valve screws set tight down right now (though I am hesitant to tighten too much, and I wonder if I am really compressing the springs). I know this is not correct for use, and I will set to proper turns once the jack is working. Thanks again Hiball. I know this jack is not...

Yeah, everything is back in proper place, and I think are all seated ok. Note that the safety valve leaks when I open the release valve, but not when the ram is holding a small load. That is the part that has me confused. Thanks again.

Thanks for the reply Hiball. The 2 piston pumps are the same size. I tried both purge methods, no change to jack functionality. How difficult should it be to lift the lift arm, it seemed to resist quite a bit. When I had the pump removed, I could cycle the ram piston fairly easily by hand, and...

Thanks Hiball for all of the info here, very informative. I decided to try to repair a free HF jack I got from a neighbor. It is a 1-1/2 ton quick pump aluminum racing jack, model 60569. The right side piston got stuck half way on him, and he left it that way for a few years. I removed the...

Yep. The one part that I wanted from this "donor" machine, and it is different/modified. Guess I gotta find another machine ....

Thanks for response FrankLee: the diameter of the new spindle is 5/8", with very litte to no taper. That spindle is also 1/4" shorter than my original one. Yes on the thick washer, see new pics. And I do not see any provision for a screw through the chuck into the spindle. The chuck was...

So I am continuing work on the parts machine, got the chuck off and saw this on the spindle end. Is this OEM, or modified? The end of the spindle is much shorter, no noticeable taper, and a milled flat. The newer to me spindle is on the left on the 1st pic, and bottom on 2nd. The other...

read through this thread. Its alot, but FrankLee and others have done a great job presenting all the info. https://www.garagejournal.com/forum/showthread.php?t=227480&highlight=craftsman+drill+press

FrankLee: thanks again for your assistance. - yes the chuck is a Supreme 6T33C. - there is old grease everywhere, the quill cavity was packed with grease. The quill lock spring was filled with grease. The set screws on the spindle bearings were replaced with more grease zerks, and that cavity...

and here is the earlier refurbished machine for reference, thanks to this forum and especially FrankLee. .

As I had mentioned last fall, my CMan 80 works well except for the run-out. I found another drill press that I am hoping to remove the spindle and try in the refurbished machine. It is a 103.23120. I have not found the manual yet for this exact model. - overall good shape, the PO ran it...

Jim: nice work on the 80/100. The pipe WTF is too funny.

My view is that there is nothing inherently wrong with "making more money". We all do that. Businesses need to make money. And quite often they can make lower quality products because that is what most people will buy. The consumer (for the most part) sets the market, not the producer. And...

anyone need any parts from a 103.25400 Dunlap tilting table saw? The table and fence are off in these pics.

forgot I had these sockets. anyone need?

picked these up recently, in pretty good shape. .
