I just changed he bearings on my 1642. I did it because you could grab the end of the shaft and physically move it to make a clunk. I changed the bearings to the Japanese sealed bearings. All went well. Unless I tighten the jam nut very tight I still get the clunk. Does this mean I need a new wave washer. Also the front bearing seems to get hot. When I put in a drive center it is very warm to the touch when I take it out. I would appreciate any help from anyone who has changed the bearings in a Jet 1642.
PS: Took it apart again this morning. I seem to be running out of threads with the jam nut. hmmm.
Too bad I don't have a service station near here.
