(Ridgid 1550 drill press)
When I turn the crank handle to lift the table up it gets stuck and doesn’t want to move,but going down is smooth,the only way I can move it up is by lifting the table with one hand and turning the handle with the other hand wiggling it back and forth(the handle).
I looked at the diagram and it looks like the parts involved are: “pin gear”,”a gear helical”,and a” worm elevation” in the lifting mechanism,I’m about to go to my shop and see which one is causing it to bind.
I was wondering if any of you has had this problem with any drill press before ?how did you fix it?
all comments are welcome and appreciated.

Sounds like a poor fit between the gears. I don’t think it’s something that can be fixed without taking it apart and replacing some parts. If new, you should send it back to Ridgid. Unless you are an expert machinist, this doesn’t sound like a diy job.

I have the same press and haven’t had any issues like that in the couple of years I’ve had it.
Take the table off so you can get a better view on what’s going on in the gear mechanism.

Two other things to look out for:
Both of the small knobs that lock the motor in place (the ones you loosen when changing speeds) broke on mine. Ridgid sent me replacements that came from gardner and they haven’t failed since. Here's a detailed review that has the same info in it, including what size to get if they fail again.

The other thing I encountered is that the center pulley shaft started to rust and became really hard to move; I noticed it when changing speeds. I was able to pry the pulley up and used a scotch brite pad to get all the rust off of the shaft and inside the hole it goes in too. Once the shaft and hole were clean I waxed both to hopefully prevent the issue again.

How ‘bout a dab of grease on the gears? They might just be a bit too dry

Loose gear connection. Maybe a pin has slipped out of place and is letting it slop around when pressure is applied to move up, there is less pressure when moving down so is is less noticable

Well,I just came back from my shop after spending 5-6 hours taking it all apart ,putting it back ,(twice) to finally make the lift mechanism “workable”,its not going to be properly fixed without replacing the worm gears(two parts).
The problem with it is ,the elevation gear and the worm gear do not mesh the way they are supposed to,I guess the last owner really abused it,the worm gear was all worn out so much that only partially engages the elevation gear.
I ended up using spacers and shims to to tighten things up ,it’s working alright going up ,but going down it still slips a bit,overall I think I can live with it.and still love it just as much lol.
Thank you all for your comments and help,it is sincerely appreciated.
Ken.

Check ereplacementparts for the necessary parts.
I just did a quick glance and if it’s the parts I’m thinking of, it’ll cost about $13 + shipping.

Thank you nite walker,I will have to look into it soon,I’m a bit hesitant about replacing cheap oem parts ,the worm gear and gear helical that I had in my hands today looked so cheap and crude.
I may still order them since they are cheap enough but I have a feeling the whole mechanism will still be sloppy and loose,even with the new parts.

If those are in fact the parts needing replacement, I can’t see the problem persisting once replaced. And since you have the press now and it hopefully won’t be abused, it should function as intended.

I had the same issue with this DP and also another one.
I took them all apart and found the gears were fine, just not aligned correctly. I greased them well and reassembled them. If you can see in the photo, there are three washers that I installed to take up the slop and align the gears properly. The other press only needed two washers. None of the gears were machined to look pretty , so if they’re not actually broken, this fix may be all that you need to do. Best wishes.

ps: I believe that the former owners forgot to loosen the table height clamp and forced the gears out of alignment when they tried to turn the crank handle.

Dusty,thank you for taking the time ,the picture helps visualise better.I will try it with a washer or two on the outside,I do have a spring washer inside ,behind the crank entry hole to take up the slop ,now the lifting action is good but when lowering the table ,there is slippage.May be I’ll remove the spring washer from inside and try it the way you have it ,I’ll probably add one or two more if need be.

Nitewalker,point well taken,if the washer spacers don’t do the trick I’ll order them and see how they perform,it is likely some slop will still be there but the washer trick should take care of that.

Thank you both,I’ll keep you posted.

You’re welcome. I hope it works for you as well as it has for me both times I needed to do it
Don’t forget the grease inside on the gears : ) Don’t make it so tight with the shims that it is hard to turn. A little play is needed for smooth operation : )
