Hey guys. I had to replace the oil seal on the left wing gearbox output shaft. From the bottom I pushed the seal in far enough to pass a slight groove cut into the housing, almost something like an inner snap-ring would go in. But instead there is a metal protective washer with an outer lip ring that seems to go into the groove. However, I don't see how I can get it up to the groove without force which would bend the metal protective washer. Imagine it is like placing an inner snap-ring in with a rigid snap-ring.
My description makes paints a perfect picture for me, but I'm guessing it's not the same for you. Just for description, imagine looking straight at the bottom of the gearbox. Think of it as a 4" piece of pipe with 1/16" wall thickness at the very end. Then going deeper into the pipe just a slight distance, the wall thickness increases to 3/16" with the extra thickness to the inside of the pipe. So if it was 4" O.D. pipe, the end would be 3-7/8" I.D. due to the 1/16" wall thickness. Then slightly farther into the pipe, the I.D. decreases to 3-1/2". So the decreased I.D. leaves a shoulder/lip inside the pipe. The inside of the pipe remains 3-1/2" the rest of the way except for the "snap-ring groove" that is cut 1/16" deep around the inside of the pipe. This groove is 1/2" deeper into the pipe than the first lip.
Now the protective washer measures 3-5/8" O.D. including the outer loop ring. It will easily fit in the end of the pipe that measures 3-7/8". But it hits a brick wall where the pipe reduces to 3-1/2". I need to get this ring another 1/2" deeper into the pipe so that the outer ring will fit into the 1/16" groove where again the inside measures 3-5/8". So how do I get it in?
It may be easier for someone to disassemble theirs rather than imagine my description. Hopefully someone is familiar enough with this to help.
TIA
