oldhudson Posted July 28, 2015 Report Share Posted July 28, 2015 My scroll saw is a Delta 40-540. Today I decided to put oil on the moving parts for the first time in a long while. On this unit the lower arm is driven by the motor through a short link and the movement is transferred to the upper are through another link at the ends of the arms. I discovered there is quite a lot of play 1/4" or a bit more in that connection. I'm sure that's not the way it's supposed to be. Has anyone replaced this part on their Delta? And if so is there info you could share? Thanks for reading. Quote Link to comment Share on other sites More sharing options...
Lucky2 Posted July 29, 2015 Report Share Posted July 29, 2015 (edited) It should be just a matter of removing two special screws, and then install a new connector link. After that is done, just install two new screws, or, use the ones that came off of it. I highly recommend getting new screws for it, the old ones probably have a ridge in them from all of the use the saw has seen. While your at it, you should also check the pivot screws to see what kind of shape they are in. If they show much wear, now is the time to change them while the saw is apart. Plus they should be removed to grease them. The grease I use is called Red & Tacky#2, it is red, and it is very tacky which you want it to be. It comes in a tube the same as other grease does, and to apply it, I use a large sringe with a dull needle. I hope this helps. Oh yeah, all of the parts that you need shouldn't be very expensive, at least they weren't when I bought them a few years ago.

heppnerguy Posted July 29, 2015 Report Share Posted July 29, 2015 You can go to the Napa auto store and buy some synthetic grease and also a needle tip for your grease gun and grease all the bearings and moving parts inside the case of your saw. This is supposed to deca superior job of lubing that is supposed to out last any other method you can do. Dick heppnerguy Quote Link to comment Share on other sites More sharing options...

Dick heppnerguy The manual that came with my Delta calls for lubricating with "light weight oil", I've been using 3 in 1. It seemed crazy to use something like that but I'm just following their directions??? Quote Link to comment Share on other sites More sharing options...
amazingkevin Posted July 30, 2015 Report Share Posted July 30, 2015 my dw788 is wore out bad from my abuse .I took it apart as much as i could and cleaned out the old lube in the needle bearing and repacked them with Valvoline synthetic grease (heat seeking car bearing grease) There was two bearings in the front of the saw that needed it worse than the rest i greased but i think you need to press them out.I Would have tried but can't stand down time away from scrolling .So i put it all back together and i am amazed I snugged up all the play the saw had and my tension dial says 1.5 when tight on the blade.I highly recommend this to all dw788 owners.Using light weight oil just runs right back out..Maybe for a new saw when things are close tolerences but a wore out one needs grease that will stay there.Over packing the bearings with grease is a lifetime fix Quote Link to comment Share on other sites More sharing options...
heppnerguy Posted July 30, 2015 Report Share Posted July 30, 2015 I agree with Kevin. I too need to take my saw apart and do this but I also hate down time even though it really only takes a couple of hours so no real excuse here Dick heppnerguy Quote Link to comment Share on other sites More sharing options...
