Mine knock pretty bad and I'm considering replacing. I see this can be done by just dropping the oil pan and without removing the crank or pistons. Has anyone done this and are there any things I should be aware of or also do while there, besides the engine oil pump? Thanks

Haybaker,
I hate to see you go through all of this work, only to find out that you have other troubles that should have been addressed while the engine was apart.
If your bearings are worn enough to cause the rods to knock, I have reason to believe that your rods, wrist pins, and pistons will also show signs of metal fatigue, due to work hardening.
On top of all this, your rings are probably due for replacement, as well.
All of this work can easily be accomplished when the engine is removed from the tractor. You'll also be able to inspect the valves and valve guides when you take the head off. When this work is being done, you'll be able to remove the ridge from the top of the cylinders, as well as be able to run a cylinder hone into each cylinder.
None of this work is expensive, if you do all the labor. However, by taking short cuts, I fear that you may end up doing this all over again in the near future.
Joel ....

Not really what I wanted to hear, but it's definitely what I needed to be told. Ha-ha. You're right though, no sense in doing it twice. I consider myself an unwilling mechanic, it just doesn't come naturally to me. But it's one of those necessities of life, wrenching that is. If I could afford to have someone else do it, I could probably also afford a newer tractor. Thanks again. ....
