Our Mini OldHam wobblers support 16mm hole layouts for AntiBacklash or regular leadscrew nuts. No need to replace your yokes, or even affect your alignment, simply bolt these in between your nut, and your yoke. The oldham takes care of the rest for you. We have designed these to work with 16mm leadscrew nuts. The oldhams are held together with silicone orings rated for 200C. Note: These items ship with m3x8 cap head screws to hold on the nut and 4 of these screws come with each oldham in the kit. For example, if you order a set of 3, you get 12 m3x8 screws. Installation is pretty easy and you can tailor it to your needs, but here is a guide that should help. See the picture and stack information below: You use the holes in the oldhams however you need to use them. Sometimes leadscrew nuts are tapped, sometimes they are not. It all depends on what you have.The orientation is as follows (if the leadscrew nut is tapped):- Bed arm - 1/2 of the Oldham with through holes attached to bed arm, attach the O-rings before you tighten them down - Slider (white plastic part) - Other 1/2 of Oldham - Connect the O-rings - Leadscrew nut - facing down away from Oldham - Screw leadscrew nut to 1/2 of Oldham If orientation is different, change it up so that you use the hardware in whatever configuration allows it to work, but the general stack should help. We include a small T shaped tool which is stored in the lid of the OldHam box that can help install the O-rings. Fingernails can cut them, but we did include spares! If you need replacement orings, you can order them from Amazon: https://a.co/d/gax23oE Installation into the printer is pretty easy too. Here are some basic instructions for that process: 1) Remove the bed from the yokes or arms and set it down inside the printer. (Yes you may have to clean out the bottom of the printer. :) 2) Detatch your Z Yoke from the Z slider making sure to hold on to the slider, and secure it with some masking tape so it does not slide off the rail. You do not want to repack bearings.3) Loosen the coupler holding the leadscrew too the stepper motor.4) Slide the leadscrew with attached Yoke and A/B Nut out of the printer.5) Remove the O-rings from the Oldham using the provided tool. Put each side of the T under a part of the O-ring that has the little round cutouts on it. Then push up and the T will push the O-ring off. Using fingernails can break the O-rings.6) Install the Oldham with thru holes to the A/B nut7) Reassemble the Oldham with the O-rings. You can use the tool and hook the O-ring on it and gently pull it up till the top of the O-ring holds onto the pin in the top of the Oldham. Angle the tool so it is flat with the top of the Oldham, and slide it out thereby seating the O-ring.8) Attach the other side of the Oldham to the yoke. (See the 3rd image in the photo gallery).9) Reinstall your yoke and leadscrew into your printer.
