Couple years ago I replaced the bearings in the spindle on my ancient 1950's yazoo. Well this morning I noticed a little play, but didnt think whole lot about it. At least not until the casting broke apart. Took shaft out of spindle and found bottom bearing was seized with lot grass wound in around it. Bearing had really wallared out housing and created vibration which destroyed the aluminum casting altogether.
Ok, new spindle even if it was available for this application would be too pricey. Looking in my scrap pile think I can make a new housing out of some thick wall steel tubing and weld a flange to it so I can bolt it to deck. Have to replace the seized bearing of course.
This is all fine and good, but I am wondering how to make it so grass cant wind in between blade flange and bearing. Would a little collar welded on outside of housing made to go around blade flange (its round) flush to blade do the job? If not then anybody have better suggestion?
