How to Repair a Table Saw Blade Lifting Mechanism
Вставка
- Опубліковано 5 бер 2021
- The elevator on my Ridgid R4512 table saw all of the sudden broke on me. It turns out that the gears needed a little cleaning, sure, but the main problem was that the turn crank slipped out of alignment and wasn't making contact with the gear that drove the elevator. I found a lock washer that had popped off, put that back where it was supposed to go, and removed an old washer that had warped out of shape.

From experience, I would expect there to be a flat washer between the original e-clip and the stationary boss that the shaft goes through. The purpose of a flat washer, aside from filling the obvious gap between the circlip and the boss, is to insulate the turning of the shaft from the stationary boss. Without the flat washer, as the shaft turns and the clip with it, the clip can stick or snag on the fixed boss (especially if insufficiently lubricated) and pop off the groove. If the e-clip has "self-ejected" and needs replacement, a circlip - not an e-clip - with a nearly full-circle inside and the "eyes" outside of the circle, can be a better choice here. Just measure the shaft's small diameter inside the circlip's groove.
This expert comment just earned the top spot as the pinned comment. It will definitely help others. Thanks!

So boss-flat washer-circlip-flat washer- nut?
@@dawylan1 Put the flat washer on first, then the circlip.
Just wanted to reply and say that this does indeed work. For the R4520 (which is what I have, it's basically the same thing as the R4512) and R4512 the groove on the shaft is 14mm, and the shaft itself is 16mm. I got some 14mm snap rings and they work but they don't stick out of the groove that far so you need washer that is really tight to the shaft. I had to buy one with an inside diameter slightly smaller than 16mm and sand it until it fit. They didn't have metric washers over 12mm at HD, so I got a spacer washer sized for 1/2" bolts IIRC (the actual inner diameter was ~15.5mm).
If you want the actual e-clip on there, which is quite a bit beefier than the snap rings, you have to order it either from the manufacturer or a website that sells Ridgid replacement parts. It's not a standard size metric e-clip that you can get from a hardware store either (the common metric sizes step from 12mm to 15mm so either way too small or too loose). On the parts diagram for the R4520 and R4512 it's called '14mm retaining ring'. I didn't bother for now because it's a $2 part but they wanted $25 for shipping, but in case anyone else is trying to fix their table saw I thought I'd mention it.
While it was not a complete solution there was enough info in your vid to get me going in the right direction! Just needed to add a second snap ring on the other side of the Boss!!! Thanks for posting it!!!!
I can't begin to tell you how much I appreciate finding this video. Thank you.
Just found your video. I purchased multiple clips and secured them one at a time into the groove on the height adjustment, rod but none of them stayed on the shaft. They would all pop off after a few turns at best. Instead, I pulled the rod out, clamped it on my drill press, and drilled a hole through it where the clip would normally go. Then, I re-inserted it and ran a paperclip through it. I was going to use a cotter pin but what for? Now, it works perfectly. I just don't think the table saw was made very well to begin with but at least this way, I don't have to buy a new one. Score one for the drill press!
NICE FIX!
Kristopher - thank you so much for making this video. I have a completely different saw, but this is really helpful. My saw blade is rocking back and forth when I raise and lower it which I discovered when I was trying to put in a faux fence for a jointer jig. I noticed that the blade pivots about 1/16 of an inch - and as your video points out, it may be caused by a few things. I already put on some WD-40, but I think it needs a good cleaning and I also need to look at the 3D diagram that the replacement parts store has on its website to see if there may be a missing or loose part that needs attention. My saw is a Skilsaw SPT70 by the way. It is the first Worm Drive table saw built by Skil. Thanks again.
0:31 Did you just say little bit of sawdust? 😂
lol, yup! 😅
Dude you saved me thanks the video was everything I needed to find out.
Love the channel!!! New subscriber!!🔥🔥🔥🔥
Thanks for the video. Exactly my problem. Happy working.
Oh my god I've sat with my table saw not used for almost 2 years now because those washers fell off, and Ridgid support only told me to go and bring the whole tablesaw to a certified maintenance shop...and I have no truck. This is the entire issue?! ...God damn it! Thank you SO MUCH.
Hey man, you're welcome! I hope it's as simple a fix as this for you. Good luck. There are some helpful comments here from other guys who had the same problem, so be sure to check them all out for some other pearls of wisdom.
Great video, I have to clean the sawdust out every once in a while just so it moves smoothly.
Outstanding video and should fix my saw! I very much appreciate the effort to create the video and help folks fix their saws. You could put Rigid R4512 and R4520 in the title and get more views. I found you by accident.
Even though I have a Grizzly Table Saw, my blade vertical movement has failed and the adjusting wheel just turns but produces no action on the blade. Your video gives me some direction on what to look for. Thanks very much. This was a well-made video and very helpful. Thanks very much.
Same here! Great video that has me headed in the right direction.
Thank you!
Hi Kris, great to see you in this video! My Powermatic has a similar problem but I think in my case it’s a worn worm gear. It’s an old saw so I’m afraid the part’s not available anymore. Yes, there’s very little info about tilt arbors out there. DW
Thanks Dave! Hope you find a creative solution to your Powermatic problem. Happy woodworking :)
Thanks for the video. Same type of thing happened on my 22 year old Ridgid. Lucky that I had not vacuumed the snap ring thing. Thanks for this video.
I'm glad it helped. Happy woodworking!
Thank you very much, well done! Hope my 4513 looks in the same in there:-)))
You just saved the makerspace table saw. Thank you!
Nah man, I just provided some inspiration - YOU are going to save it! Makerspaces are awesome. Thanks for supporting one.

Thank you! I think lock rings are a common hardware store item.
Thank you for this ! I have a ryobi and there is no pictures or diagrams that can show me exactly how it should be set up . I know it’s lost the c ring washer, might have to check my sawdust bags ! I ordered a new one anyways but have no idea how to properly place it, the set up on the ryobi is different than yours 😫
I had same issue with my Grizzly hybrid tablesaw. I replaced both rhe spacer and e-clip but i think the lifting mechanism is so dirty that I have to exert too much pressure on the screw that it popped off again. Not sure how to clean it well however.
I have a Jet ProShop that has a very similar setup. My retaining clip also fell off and made raising and lowering the blade very difficult. Because I couldn’t raise the blade all the way up, it also affected the arbor lock button that allows you to easily remove the blade. I put the retajning clip back on and all is well. Might be an area to clean once in awhile. Also, on the Jet you need to tilt the blade all the way to be able to even see the clip which is in the middle of the shaft instead of the end like the Rigid you show. Manual was zero hell in this issue. I have no idea why it would pop off in the first place. I know I’ll check it every time I vlezz as n the sawdust out.
That clip is also called a snap ring. You can find them in the specialty hardware drawers at big box home improvement stores.
Excellent video, a question I see that you have used the saw for a long time, would you recommend buying the R4512 Circular Saw? Do these types of Circular Saws use Belt or Transmission Belt?
My bosch gts saw lift mechanism got so stiff that the spinning handle wore out and is spinning free. Have you got any idea if the threaded rod should be lubricated or dry?
Hi Kristopher - Thanks for the video. I have had my 4512 for a number of years and really like it. The one thing that I have run into is the mechanism to raise and lower the blade works fine (have not run into your issue - yet) but it is not as smooth as I would like. Do you still own and use the saw? Did you ever figure out how to clean and lubricate the mechanism?
Thanks Again
Hi Bob! Glad you enjoyed the content. Yes, I still use this as my primary saw. I love it. For lubrication I grease the threaded rods once a year now. That does the job perfectly. Make sure to clean out the sawdust first, of course. Happy building.
It's a bit late and you putting already fixed it. But I grew up Cain that piece a snap ring, but I'm in south central Oklahoma and different places can it by different names. But you should be able to get them at hardware stores, just bed to know the size of that rod. Should be able to pick up a couple for pretty cheap. Hope you got it taken care of. Mine has a bit of a different problem I think tho. I had turned it to 45 to make a chamfer on the corners for a picture frame I was making and had lifted the blade up to check I was at 45 and then I couldn't get it to go back down.. I feel like the rid of jammed on the teeth that shut in the screw part. But tried a few things and ended up waking away before I ended up needing something up cuz I was a bit irritated.
Hey I’m having this exact same issue with my r4520 but I can’t seem to get the rod to back out far enough to even show that groove the lock washer clips Into. What would you suggest I do? I have video and pics if needed. Let me know please thanks ! There’s literally no videos or any info online about this issue other then your video sadly.
I have the same issue, any luck?
I had this issue with my R4520. To be able to spin it far enough to get the E-clip into the groove on the shaft you need to take off part of the handle for adjusting the height. On the front of the saw there's the knob, a small washer, and the wheel/handle to adjust the blade height. Remove the knob and washer. I think there's a spring that pulls the rod tight towards the front when the knob is tightened. Once you remove the knob it'll be able to go all the way towards the back of the saw. Just push on the wheel so it engages with the pins and crank it counter-clockwise until the groove on the shaft is sticking out enough for you to put the washer + E-clip back on.
I appreciate your video. Now I will attack the same problem on my Grizzly.
That c-clip seems pretty loose on that shaft. Get a new one and put a flat washer on first to bear against the c-clip.
He is definitely not mechanically inclined!
hey at 0:59 the blade elevator bar is right out of the hole. That is what I'm currently dealing with. How did you get it aligned so that it would fit back into the hole? Right now it's missing it by a small amount because the teeth of the gear is pushing it slightly out of alignment. Thanks so much!
Well, I used force. Ha! Seriously, I had to push forward while turning the wheel clockwise. Good luck with your fix. You can do it!
I just ran into this problem and can't figure out how to put it back? Did you manage to fix yours and how?
@@marciodebarros Hey I did! Kristopher said to really force it, push forward while turning the wheel clockwise. Thanks for reminding me with your comment I forgot to thank him. Good Luck!
@@MidwestManMountain Got it Forgot to say thanks!
the washer is called a circlip
That thing is called a Snap Ring, it snaps onto the shaft.
or Circlip
overhaul i want you to overhaul, i'm updating my machine please
It's called a "C" clip.
THATS A SNAP RING MADE OUT OF SPRING STEEL, USE A WASHER BEFORE YOU PUT THE SNAP RING BACK ON , WASHER WOULD HELP REDUCE ROTATING FRICTION ON THE RING. MAYBE THAT LOOSE WASHER IN THE BACK WAS WHAT IT IS FOR ?? MAYBE THIS WAS APART BEFORE YOU GOT THE MACHINE/SAW !! BEST OF LUCK, STAY SAFE MATE , WATCH YOUR HANDS/FINGERS AT ALL TIMES !!
Circlip
it’s an E clip not a lock washer
Some people call them Jesus clips because every time you go to put them back on they fly off and you lose them. Hence you start cussing and use the Lord's name In vain. Super glue?
lol, I've heard of this term before
I learned to avoid Rigid brand.
