For just a little more info.  I bought this tractor as is about 3 weeks ago out of South Central Indiana.  The guy had apparently had it blow up a week or so before I bought it.  He was not a PK collector, just a guy who mowed with it and said he had owned it since 1982.  I think it is a '77 model.  He had a video of it running on his cell phone with the damage.  He responded to a want ad I had posted for PK parts and transmissions and made me a good deal on the whole tractor.  It has the dual transmissions.  He had no idea what caused the damage, I deduced it from the missing balance gear and the other things I saw.  I pulled the head and it had a standard piston and good bore, so from what he said and what I saw, I am fairly certain it had never been taken down or rebuilt.

Hmmm the 16 Auto has these still intact, guess I better take them out.  The Gravely walkbehind with the K301 never had them, so I guess not all K series Kohler came with them.

I have a k341 from a genset. It didn't have them.

 

Does anyone know what makes them come apart? They're a pretty good chunk of iron. Is it the keeper that holds them on???

I have seen the keeper clips come off, bearings go bad causing teeth to not mesh proper, and in a few cases, the pins come loose in the block.

Makes me glad that I listened to the advice given by many here on the site to remove them from my K341 when I had it apart to fix the governor.

I asked this back earlier in the thread but don't believe anyone answered... For those of just that don't know, how can you tell if the balance gear is in there without taking the enging apart? Are there certain spec' numbers that that do and don't? certain OEM's that had them and didn't? I'm up to 5 K engines now ranging from 1972 Wheel Horse to a 1996 replacement engine... and have no idea if any of them have this gear.

The cool thing is that it still ran. Nothing like a K series Kohler!!!

There is no way to tell if an engine has them with out removing the oil pan.. Some applications had them, other applications didn't.

I don't know if there would be enough room to see by taking the cam cover off and shining a light in. Kind of has me curious now to see if you can tell that way.

If you look at the crank side of the engine, you will be able to see the holes for the pins that the gears are on. I went and took a picture of a k321 I have apart right now. I also drew two arrows on the block, pointing to the holes for the balance gears. If it has these holes, then it has (or had at one time) the balance gears. If the holes are not there, then it never had the balance gears.

This is only from my own detective work, and is not official in any way.

What is involved with taking them out?  I know my K321 has them.  I saw them when I was working on my ford LGT145.

thanks

You have to pull the crankcase cover off and remove those pesky buggers before they bite you..  It is possible now to have the crankshaft ground to balance the engine and make it run smoooooth!  PM me for info..
