When I ran my F-20 today it developed a knock.
I removed the engine side covers and the connecting rod on cylinder one is loose on the crank shaft. Is there any easy fix to this. I just finished putting a lot of work into this tractor and was ready to start enjoying working wth it and now this happens. I hope it dosen't take a lot to resolve this problem. Any comments would be appeeciated.

My suggestion would be to drop the oil pan and inspect the rod bearing connection. If it is tight, then it sounds like a worn rod bearing.

Is This a big job, or is it just a matter of getting new bearings and replacing them? The connections seemed tight on the rod when I checked them. Can this be done through the access hole or must the pan be droped? Thanks Red

If the rods seem tight from the inspection plate, then the knock is probably another problem. Have you adjusted the valves recently? If you have too much clearance, you can get quite a bit of noise.

I think the rods have shims to adjust bearing clearance. Might just luck out and be able to adjust them.

The rod is not tight on the shaft, the bolts are what are tight. There is play between the rod and the crank when you move the rod back and forth . Any suggestions are appreciated.

Your F20 has shims for adjusting the bearing. You will have to remove one or more equally from both sides of the rod. There will be thin shims sandwiched between two thick shims. The thin shims are the ones you will remove. You don't have to remove the bolts, just loosen them and pull at the shims. They don't fully surround the bolts and will come out. Try one pair at a time and then tighten the bolts and check for fit. I have done this with my F30.

I have been studying what you have said about the knock on the f-20. First of all the back and forth movement of rod on crank is normal, it is built in. You need to make sure of crant to rod bearing clearance. This would be vertical movement. You really need to check this clearance at top of stroke and then half way down or when the through you are working on is horizontal. This for checking flatness of crank. Or better yet would be to mike the shaft. Yes this can be done fron inspection hole. That was the idea of inspection hole, you can remove the piston and put in rings this way, not easy but can be done. If the rod is truly loose I would want to know why it did not get oil. Pan is not hard to remove I would pull it and see if the oil line is pointing at the dipper. Or if it has came loose and not oiling the rod at all. Also the dipper may be messed up or have something in it thus keeping rod from being oiled. My best advice at this point is check evgerything from oil pump to oil distribution and dipper. Ps clean oil pan and run water through the main tube check for leaks and where waater shoots out will give you good idea if oiler is pointed ad dipper. You can adjust rod bearing by taking out shims, three and one half thousands to five is good fit. Use plasti guage to check can be gotten at local parts store. Remember Check and find out why the problem has occurred.
