Pixburd- Did you shorten up the actual OEM plastic bushing or are you using something else inside the barrel adjustor on the transmission shaft?
Yes, I shortened the actual OEM plastic bushing. I extracted it and cut off a little more than an 1/8 in.
Then I ordered 2 more Honda OEM dust seals (each rear wheel now has two seals.).
The shorter bushing gave me some space on both sides to add bearing grease.
This was not the first time I had cleaned up the bearing area and added grease. Past maintenance never lasted long because one side had no seal or grease.
So far so good. I thought about this fix after some research reading about several other endeavors and contacting the local Honda repair shop. His comment was that Honda by far makes the best engines, but they failed with the rest of the mower, especially around the wheels.
I still may end up putting ball or sleeve bearings inside like others have done. I'll wait and see.
