Hi everyone, I have a K301S in my 1977 wheel horse that I bought this past summer. Supposedly rebuilt, runs good no smoke. After finishing mowing my lawn yesterday, removing my earplugs I could hear more noise than I remember hearing from my engine prior to that moment. Inspected engine more closely and determined that excessive crank play was what I was hearing, pushed on flywheel side, then on clutch side and can see a lot of movement back and forth and hear klunk when pushing. When engine is running and clutch is engaged it side loads crank so you dont hear the klunk from the slop, but as soon as you disengage that side load you start to hear it. When I came home from work today with my Magnetic base dial indicator I went straight to the pole barn and checked crank play. Cold engine and 48 degrees out I could see no movement so put dial ind on flat portion of flywheel screen ( I know its not the best spot) and it showed only 6 thousandths movement..... Thats great. Started and ran engine with tractor parked for about 5 minutes I think, shut down and pushed crank both ways and that darn klunk and slop is back again. With engine warm put dial ind back on and get 33 to 36 thous crank end play! I can push on flywheel and then slowly engage pto clutch to push crank back other direction and klunk... its a jumpy movement which is what has me pondering whats happening, If you get what im saying I smoothly apply pressure to push crank back and at one point it suddenly moves. Could the bearing not have been in the bearing plate all the way when the previous owner reinstalled, and I am having that bearing move more easily side to side when its hot? I know I want 3 to 20 thousandths end play, Can anyone here speculate what I may expect to be the problem? I was going to get gaskets and reset crank play, do you think I couldn't get a lot of movement when it was cold just because a tighter fit to the flywheel bearing or am I being dumb? Perhaps I should repeat the cold test using a brass punch on each side of the crank to see if I get the bad crank play. Sorry for the long post, any ideas appreciated.
