Hi Tom, The photo is The Old, or Original filter I took out of the TO20 to replace. Yes, it has a dome type top. It is identicle in all measures & specs to the bottom side as well.This original filter is about 4-1/8" at it highest points. & 4" wide. Outside of the tappered top & bottom, I am primarily trying to show that the hole in center is set down about 1 inch on top, & bottom, in addition to having more steel bowl type clearance outside the hole. The replacement NAPA gave me, 1107 WIX, is a symmetrical canister type. Same in height at its highest points, but less in wigth, (Mabe 3-1/2") dont know , as it is installed in the tractor. I wasent aware Jason had experiance with this so I will reply to him again. The spec diagram helped a bit, but mostly to confirm I put it all back together correctly. 1 thing on the spec diagram though, is that spring . That may go down in the top of the oil filter to keep a small nylon ring or something against the inner resesed hole., "when I get the correct 1, or put my old 1 back in I will check it out.") My smoke & poor running issue that happened after this darn simple oil & filter change, is likely due either to the wrong filter, Or the loose inner housing I have been describing, or mabe both. (Picture a paint can with no top, no bottom, that is what the screen & filter go inside of. Mine is loose. Mentioned earlier, but I pulled out 2 tiny pieces of metal that were laying loose. 1 Mangled, 1 not. They may be tabs to hold this "paint can" housing tight. Thanks again for the Part #s & description .
Think I will try again, to order the original Fram C153 I mentioned in 1st post. THAT, I saw a photo of, and it is exactly what came out of the tractor, what is in the photo above. Jason said stay away from Fram for some reason. Im simply trying to find New, exactly what I took out. Well??? I best get back to it. best regards, Jerry
