This new "Heavy Duty Pan Seal Kit" *Kit Includes: 1 Pan Seal, 2 Stainless Steel Flat Washers, Stainless Steel Snap Rings, Explosion Diagram, and Installation Instructions. ***You will need Snap Ring Pliers to Install the Snap Rings. will fit the models listed below: Toastmaster Breadmaker's Hearth (Breadmaker Cook's Oven) Automatic Dough Bread Maker Model Numbers: 1139 1193 THANK YOU! Bread Machine Parts Finder ***Important message about removing the seal in the pan: 8MKIT-HD *(You will need Snap Ring Pliers to remove and install the Snap Rings.) *(You may need an E-clip installation tool to install the E-clip.) If the pan's shaft is still secure, then you may push the seal out by removing the Snap Ring Wing Nut Impeller from the bottom of the shaft. Then with minimal force push the shaft up and out the top of the pan. This action will push out the seal. If the shaft will not push through without using excessive force that may damage the pan, then you may want to consider shipping the pan to us to have the seal replaced. If the pan shaft has already come loose and fell out the bottom of the pan, then you will need to follow the directions below in paragraph 2 3. ***If the shaft has already fallen out the bottom, then you will need to pry out the old seal using an old double ended can opener / bottle opener. Place a business card or credit card in the bottom of the pan to prevent scratching when using the can opener to pry out the old seal. Place the pointed end of the opener into the center hole of the seal and gently pry upward moving from side to side until the seal pops out. Please note that the seal has an inner steel frame. If all you have removed so far is a thin piece of rubber, then you will need to remove the rest of the seal known as the inner frame. It is important that you be very careful when removing the old seal. If the hole the seal is in becomes swelled, warped, or chipped then the new seal may not seat successfully. ***I strongly recommend that you do not install the new seal until you determine if the pan is in fact repairable. Please remove the old seal and then use a magnifying glass to inspect the hole for chipped off non-stick coating, pitting, corrosion, dings, dents, swelling, or warping. If any of the damage described is present, then please do not install the new seal. I can guarantee that it will not seat or seal correctly. In this case you will need a new pan. Also inspect the inside bottom of the pan at each rivet head for tiny cracks using a magnifier. If you find any tiny cracks, then you will know that water is leaking through those cracks, and a new seal kit will not fix the pan. ***Please be aware that each time you replace the seal it may not last as long as the previous seal, because the sleeve bearing in the bottom of the pan continues to wear, which causes more wobble that creates more stress for the seal to bear. The thin washers included in the seal kit are for replacing any Nylon, Teflon, or Fiber washers that may be within the assembly. You may re-use any metal washers found on the bottom end between the sleeve bearing and the wing nut impeller if necessary. If there is a metal spring washer found on the bottom end between the wing nut impeller and the sleeve bearing, then you will need to reuse it.
