Fish Posted December 31, 2020 Report Share Posted December 31, 2020 IMG_2736.MOV I got this a year or two back. It was the demo and I don’t know how much it was used. . I just noticed it starting last night and is louder today. Is the main bearing loosing grease and going bad and am I gonna have to replace it? The bearings are going in the lower front too? If I do where can I get the bearings, am I gonna have to do it all like I did with my Dewalt? Is it as easy to do as my dewalt was? I used my drill press to push old ones out. thanks for helping.

Karl S Posted December 31, 2020 Report Share Posted December 31, 2020 You can replace the bearings. Be aware that the nut on the motor is a left hand thread. Bearings can be purchased at your local bearing supplier or on line from McMaster Carr. Should not be too difficult just take tour time and if needed take pictures as you go along, I don't see you having much trouble.

P>S> the bearing that is leaking is a shielded bearing , and I would replace it this a sealed bearing if at all possible. Get the numbers from the old bearings.

kmmcrafts Posted December 31, 2020 Report Share Posted December 31, 2020 The problem I ran into with the excalibur was that the bearing sleeves couldn't be sourced.. I found the bearings but not the sleeves.. Putting new bearings with worn old sleeves might make it very short lived.. I also discovered that the whole assembly from Ray is almost the same price as all those bearings.. so even if you could source the sleeves the cost is probably more money than just buying the whole assembly and replace all of it at once. The whole assembly is really quite easy to do.. I took a lot of photos of my process and uploaded a topic about the rebuild on my saw. I'll see if I can find it and link it here. I do have the China made EX-21.. https://www.seyco.com/partspage/ OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted December 31, 2020 Report Share Posted December 31, 2020 Here is the thread of my rebuild.. you shouldn't have any issues with the front rocker assemblies if your saw is before the China made ones OCtoolguy and NC Scroller 1 1 Quote Link to comment Share on other sites More sharing options...

Fish Posted December 31, 2020 Author Report Share Posted December 31, 2020 So this is pretty much the same as the dewalt? It's older than I thought. I bought it in 2018 and it is one made in Taiwan. So it was at the wood store as the display and used a lot longer than I thought. 2017 was when it started being made in China? The replacements at Seyco should be a match for my saw- I'll check with them. Thanks for the help I really appreciate it. The only thing I'm nervous about is I replaced all of it on the Dewalt and still couldn't get it to run right. It was a type one.

Fish Posted December 31, 2020 Author Report Share Posted December 31, 2020 Sorry I uploaded that from my Iphone. I'm not sure why it didn't show the video. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted January 1, 2021 Report Share Posted January 1, 2021 Video played fine for me.. Well it is a possibility that it wont run right after rebuilding it.. I don't know your mechanical skill set.. but you can't over tighten the bolts and screws that hold the bearings and bracket or it won't run right.. you have to tighten them snug and then maybe back it off just slightly.. you don't want it loose but not so tight that it puts some strain on it. If you buy the whole assembly everything is pretty much all assembled other than one bearing at the back of the saw and then the ones at the front where the rocker assemblies connect to the link rods.. so this assembly is really kinda hard to mess up..

Fish Posted January 1, 2021 Author Report Share Posted January 1, 2021 I’m gonna look at buying the whole set. Makes more sense. kmmcrafts and tomsteve 2 Quote Link to comment Share on other sites More sharing options...
