K321 rod oil hole position
 

I started a new thread on this as my rebuild thread was getting pretty long. I received my new Ign. switch and it took care of the no voltage to coil at start up position. Had the engine all set to put in frame for 2 weeks. Installed engine and hooked up drive shaft and installed starter. Awoke this morning and was worrying about the rod oil hole position. I know it states that the hole must face the cam shaft. Just can't get it straight in my head. Any one have a picture of an after market 10 under rod installed showing the correct position of the oil hole in rod? I have searched and could not come up with any picture. I just know I am going to have to pull the engine and take a look. Thanks for all the help . Have a great day. :Cry1:

What's confusing?

Oil hole goes on the camshaft side of the motor..... Nothing confusing about it.

Don't start a new thread.... Unless you just want this one question answered. You should have put it in the engine section under Kohler motors. It's an engine question. I'd move it for you.... but.:RollEyes2:

Edit: I moved it. Sam Mac.:beerchug:

When you put the piston in just make sure the oil hole is pointing to the same said as the cam and you will be fine.

rod oil hole
 

Thanks J-Mech & Tim. Engine is all together and installed in tractor. I just can't remember if the oil hole was pointing to the cam shaft. I surely would have installed it that way. Just can't remember. If installed incorrectly, Will destroy the engine? Have a great day.

Yes it will.

On the side of the block there is a cover with two bolts in it, you might be able to look through the hole and see the connecting rod and hopefully see the oil hole.

you can pop the cam cover off or if it has a fuel pump plate. should be able to see it. otherwise the first time you rev it up it will start to slow down after initial speed up, its seizing then . saw it happen twice now when guys bought them over cause they couldn't figure out what was wrong. if you are lucky and catch it no harm no foul but they can get pretty expensive

I'm gonna throw some confusion your way. Those who have worked with these engines will know what I mean.

that rod has 2 holes. One has no consequence of pointing it a certain way, this is a hole in the rod beam that is only there to indicate that it is a 10 under rod. The important one will be on any Kohler k series rod , no matter whether standard or undersize
This is the important one, if you want the engine to last. It is in the rod bearing cap. That one HAS to be towards the cam. And yeah, being it (is supposed to) point that direction, you should be able to see it with the cam cover off, you might have to spin the crank it by hand to get it into such a position where it can be seen.
I know what it's like to have those 3 AM "oh, $#1t" moments where I snap up from a dead sleep because of having thoughts of " Oh man, did I do.....…......." and then not be able to fall asleep again because it eats at me...

Mr. Bob, BTDT!!

If you need it, there are very inexpensive borescopes now that plug into your smartphone and fit in a small (1/4 inch) hole. they have lights at the end and you can stick it in a small opening and see what's there on the phone's screen. This one is under $10.

As a note, you know the cap is machined to only correctly fit one way right? If it is backwards, you have to spin the whole rod around, not just unbolt and turn the cap.

To all the readers:
The rod cap must go back on the rod in the same position it was when it came out of the box. Mark it if you need to, so you put it together right.
