Part II
Pulled the rear wheel assembly to see if I could press the needle bearings into the wheel side of the adjuster's. The machine shop pressed the needle bearings flush to the wheel side, not allowing the insert of the grease/oil seal. I pressed it with my 6 inch vise using a 3/8 socket that would press the bearing without doing any damage. I was unsuccessful. That needle valve was really in tight, it would not move. I damaged the outer edge of the bearing making it unusable. Time to implement Plan B. I pulled the trans assembly and sanded down the entire axle. It was badly pitted toward the center with lots of rust. Upon closer inspection, I noticed that the axle on the wheel side had damage in the area where the needle bearing was. Two concentric rings, I could feel the edges with my fingers. Looks like one of the needle valves was failing and scoring the axle. See first 2 pics below. This was surprising, as the needle valves were only in a few mowings. I sanded the axle down and installed the new adjusters with bronze oillite bushings. Both ends of the bushings are sealed with the Honda grease/oil seals (epoxied). Plenty of Redline CV2 for additional lubrication. I attempted to install the shrink tubing to cover the axle, but that was a failure. The shrink tubing would not shrink to seal the 1/2" axle. The shrink tubing was 5/8", which should have been ok, but it just wouldn't shrink down. I used a hair dryer. It was a good idea, but it just didn't work out. One plus, using the 5/8" oillite bushings allowed me to insert them into the stock Honda adjusters without drilling/modification. That allowed the Honda grease/oil seals to seat very well. I epoxied them anyway. After getting everything back together, the mower offered about the same resistance on pull back (4.5- 5 lbs) as the previous needle bearings did. Got my fingers crossed, I'll report back how things go as this summer mowing season progresses. Thanks guys.
