Lubricating the Drive Coupler (Rotary Drive Coupler) in your Bread Machine.
Unplug your bread machine. Turn it upside-down. Remove the bottom cover plate. Once the bottom plate is removed you’ll see two wheels. Remove the large one. If there’s a retaining clip holding the shaft in place, remove it too. Once removed, the hardware (or “coupler”) connected to the large wheel should fall out on its own. If not, use a philips screwdriver to force it through the oil-lite bearing. Once removed, clean the shaft and bearing hole with super-fine sandpaper or "0000" steel wool. Once cleaned, lubricate the shaft and bearing hole with liquid graphite lock lubricant. NAPA Lock-Ease Graphited Lock Fluid (item 765-1382) can be found at your local NAPA Auto Parts Store or their Online Store. Allow lube to air-dry, then re-assemble your bread machine in reverse order. Before placing the large wheel back onto the shaft apply more lubricant. Enough to flow down the shaft and into the bearing assembly. Then place the wheel back onto the shaft. If your breadmaker is extremely difficult to disassemble, try this instead: Unplug your bread machine. Place cardboard, shop towels, or several sheets of paper towels under your bread machine. Open the bread machine’s lid. Remove and set aside your bread machine’s bread pan. Shake liquid graphite lock lubricant well. Generously apply the lubricant over the coupler (located at the bottom-center of the baking chamber), allowing the lube to flow up and over the coupler and down into the shaft assembly underneath it. Allow the pooled lube to sit and penetrate for at least one hour. Afterwards, soak up any excess liquid remaining. To insure that all the liquid has evaporated, please wait an additional 24 hours, with the lid open, before using your bread machine.
