12hp Kohler oil pan
 

I have a cub 106 with a k241 that threw a rod, finally got around to replacing it and the new rod bolts backed almost all the way out after running for 20 minutes and now the end cap is destroyed. Have a 12hp sitting in the garage but it does not fit because it has the deep oil pan. Can I trim the rod dipper on the 12hp and use my flat oil pan from the 10hp without destroying the engine? I need to get this tractor going before the snow really starts to fly. Any help is appreciated !

You can....... but I wouldn't.

What pan does the 12hp have that it won't fit? Not a CC style pan I'm assuming, because a 12HP pan that fits the CC would go in the 106. I'd find the correct pan.


As a note, in the future, don't just replace a bad rod. Rebuild the engine and grind the crank. This is the kind of failure that happens when you do a job without doing it right. Did you not torque the bolts???

I think it came off a case, bolts were torqued. Do not have the budget to afford a full rebuild, just trying to get it going to plow my driveway. I have read in other forums that rods can be shortened but isn't recommended for tractors ran frequently on slopes.

Where in Ohio are you located? I have a few good used engines sitting here. PM me if you're interested.

Cast Iron 12HP pans come up on E-bay quite often.
Find the correct pan and you are in business.

Can somebody share a picture of what the correct oil pan should look like?

Here is an example of what a correct oil pan looks like. The cast iron is desirable over the aluminum. The mounting holes and bosses are worn...this is not a great pan! This is for reference only!!

The pan on my 12hp is similar to that one. The problem is that the deepest part of the pan sits on the crossmember above the front axle

Please take a picture of this chassis and post it here...there are no additional cross members for the frame other than the axle channel and one about half way back under the dash tower.

You maybe installing the pan backwards!!!

Ok so I'm looking at the engine again and apparently I just lied about having a similar oil pan. The one I have is just has a rectangle in the center of the pan. The cross member I'm talking about is probably what you are calling the axle channel. This is my first garden tractor so I'm sorry for not being very educated about these things lol

We are patient!:beerchug:

If you are trying to install a pan like this, it will NOT work.

This is like the pan that I have

Bad link! :beerchug:

This is the style of pan that is installed on 10 hp K series Kohlers in 106/107 models Cub Cadet.

On the last engine overhaul that I did I took my chances and Heli coiled the aluminum pan. can always swap it out if need be.... the old "use what I have" thing here....

Here is another link

DelatCub the link you posted is the same pan that is on my 10hp

That's how I normally do things as well

This pan that you linked will NOT work!!!

See post# 7 for correct oil pan style for k301 for your Cub Cadet.

I noticed that. So should the deepest part of the proper pan face towards the rear, right?

Yes:beerchug:

Ok, awesome. I'll be on the look out for one, I appreciate all the help!

You are welcome...don't forget the new gasket for it too!:beerchug:

New oil pan should be here this weekend. Was wondering if I could use the head off my k241 on the k301 without running into any issues, I know that the bolts all line up and it fits good but the spark plug is in a different spot. Not sure if that will affect how it will run?

It will be fine.

Heads are the same as far as fit. They are interchangeable. Might need a longer spark plug wire, and be sure to use the engine tin for the head that fits the head. (Spark plug hole drilled in right spot.) Check the bolts also. Some heads have recessed holes and need a bushing, some need longer bolts, ect. Pretty straight forward.

The head I have for the k301 has recessed holes that's why I was wondering, didn't want to buy the spacers to be able to mount the gas tank. One more question, I was only able to find a aluminum pan so do I absolutely need to put steel threaded inserts in it or will it be fine if the current threads are in good shape ? Thanks for all the help guys

Only fix what's broken.

Ok, thank you

Ok one last thing lol. The 12hp I have did not come with the drive cup(?) and I don't think the I have will work properly on it. https://i.ebayimg.com/thumbs/images/...EGY/s-l225.jpg
This Is similar to the flywheel on the 10hp
https://m.ebay.com/itm/CASE-224-444-...28.m4335.l8656
And this is similar to the fly wheel on the 12jp. Can't find the right part anywhere so if anyone could point me in the right direction it would be greatly appreciated!

Is it a K301? Are you needing Drive Cup or Flywheel or both?

Either way:

Looks like that one would work on my k241 but need one for k301, appreciate it though

I need just a drive cup for the k301

You can get the cup new at the link provided above. Or get one used from ebay by using the part number in the link or an updated version if one has replaced the original part number. here is a link for compatibiility.

All they have is kit for 115$ and I wouldn't even know if that would be what I need for this.

If you do not have one, then you need one. And if you have a K301, this is the one you need assuming nothing has been modified/changed (highly unlikely, but if I don't put in this disclaimer then that would surely be the case). I was able to locate several on ebay from $45 used-$130 new using the part number.

Which part number did you use? There is a a lot in the one link

you're killing me brother... :biggrin2:

Go to item 41 as seen in the pic I've attached. The pic is small, but you should be able to use it as a "map" when opening the link. P/N should be 52 755 61-S

The "kit" just includes a washer (item 6 in the same link). Search for this part number on ebay, or google, and you should find several results. BUT do yourself a favor and give it a sanity check. Do the mounting holes line up as expected when you look at how it will mate up? Do you have the old one and does it look the same?

I google that number and all I found were ones that look like they would work on the k241 but not the k301. The k301 does not have a spot for that pin that's on these drive cups, looks like it should bolted to the flywheel? I'll have to look at the engine again tomorrow lol
