Good day,

The story begins again for a lucky... or not so lucky Case 220.

Started out as a not running package deal with a 220, K341 implant, mower, Allis Chalmers converted to Case snowblower, chains, home made rear wheel weights, and home made blade.  $200 was a deal for me...

Got a new 30 over piston and rebuilt kit and kept it going for several years punishing it mostly with snowblowing duty.  The piston slap was getting pretty obvious so decided to park while I did my Magnum 16 into a 444 project (a different topic in here).  Works great.

But now to turn my attention back to this hulk after trading a Ford tractor K341 for a K241 from a Case tractor and a K361...

You are definitely thinking what I am thinking - K341 guts into connecting rod grenaded K361 with a great condition head!  Or maybe not.

The project starts....IMG_1464.JPG IMG_1465.JPG

The frame was already converted for a wide base to bolt right in...IMG_1468.JPG No idea how exhaust will config but everything else should be a bolt in.IMG_1470.JPG

I'll post now and then on the build.IMG_1467.JPG

Don't expect a beauty queen but 18hp on a small wheeled frame - the snow will be flying again!

Here is the head - seats are good and tight in headIMG_1469.JPG

Is this a 6 amp charging circuit?IMG_1472.JPG

Am installing working circuit that was in the 341 - always kept battery charged and started great. This is the installed rectifier which checks out as a 15amp unit...IMG_1474.JPG

A bit confused on that one.

I picked up a Case 220 parts tractor yesterday. With luck it will help me get 2 non-running 220s, running. I'll be left with the hydraulics and transaxle when I'm done. The hood and hydraulic cooler were trashed when a tree fell on it. Good Luck, Rick.

Sometimes picking up more tractors is simplest way to get the things you need to fix yours...

I'll need some pieces to get this going as I stole a few pieces for the 444 project (seat pivot/mount) - hood - need steering wheel for the 224...

Fun to collect xtra tractors - just get the urge to get them going too...  Brian  wpgjetfan

I think you have a 3 amp stator. Had to look it up never seen split stator before. Seen lot of different ones with coil post without windings hear and there. Did that come from tractor seems that would be battery tender for in between starts?

The stator is as attached to the K361 as I got it.  It has the 15Amp rectifier but a 3/6 Amp (I believe) stator.  Engine is silver too so am not sure what it is out of.  I'll get the engine code off of it as I printed out the parts manual to look into it.

The K341 internals are all dimensionally correct to work so I'll be having fun - connecting rod took out crankshaft on the K361 with some serious damage...  Brian  wpgjetfan

Some research progress... the dipstick was only used on one specification of Kohler K361s - all the rest used vertical dipsticks.  It is from a Simplicity tractor and am assuming it is a 1969 or 1970 model as it is the first specification on the list after a general application K361... anyone know the 1969/1970/1971 Simplicity model that would have used this engine?  Brian  wpgjetfan

Successful decode... with alot of research and very few pictures to verify.  The 1978 7018 Simplicity is the only one with the 18hp K361 - and found the evidence to back it... on this site hidden in Simplicity manuals:

 

Model   Hp          Mfr Number      Engine Model    Engine Type

7018H    18           1690366                K361QS                 23107A**

7018H    18           1690431                K361QS                 23107A

7018H    18           1690433                K361QS                 23107A**

** Kohler Engine

The series is indeed the 23107 but third on the list of the 10 or 12 builds they released - making me think it was an early release.  The picture of a 7018 will verify the short angular dipstick of this unique series.  Was hoping to see a tractor in person but a one year release... not likely.  Am hoping to wrench some more tomorrow on this.   Brian  wpgjetfan

That is the correct dipstick for Simplicity 7018/Allis Chalmers 718. All the spec numbers I have seen on these for the Simplicity /Allis application were 23107a. I'll have to check my motors and verify.

Would like to see the configuration - post some pics please.  This block is grey but am pretty sure she is black underneath. And the build code matches - will post pics when I have a chance.  Also grabbed a pic of the flywheel.  Looks like a magnet is missing or is the proper config for the 3amp charging system... Brian

Here's the build sticker:IMG_1482.JPG

I guess that cements the fact it's from a Simplicity 7018.  Although the 'a' that should be at the end is obliterated...

How is the exhaust configured?  The Case has the motor installed the other direction and not much room for an exhaust over hydro pump and close to battery... towards the operator

I have a chopped up hood that will work if I mod the sheet metal. for a rear exhaust stack type exhaust.

One thing I notice about Kohler is that stamped numbers don't mean much.IMG_1475.JPG This intake has a clear Kohler-like number on it but doesn't jive with any intake pipe for this engine... yet it is on the engine and clearly fits the engine and mounts the carb in the correct orientation.  Google the number and another dead end.

Another good example - although the flywheel being a more universal fit from K301 to K361 - of an item not having a Kohler number stamped into itIMG_1484.JPG - the flywheel has a random number...

I would venture to guess without the 6th magnet this is toast anywaysIMG_1483.JPG

I'll need to inspect the windings for damage from debris if magnet let looseIMG_1471.JPG IMG_1472.JPG

That's about it for now till I pull flywheel off of the donor K341.

A bit of work: IMG_1542.JPG

Got the flywheel off and the windings look good on the donor - and hey - all magnets in place!IMG_1541.JPG

Eventually I'll need to pull the crank and piston and begin the swap over!

Not much else new.

Good day,

Almost forgot to add the puller method used - impact wrench rattling the puller and hammering in between to loosen up the connection.

Key came out in the pulley so that will assist reinstall.  Looking good so far.

A little more disassembly of the donor K341

IMG_1546.JPG IMG_1547.JPG IMG_1548.JPG IMG_1549.JPG

Rotating assembly looks great - 30 over piston looks pretty good too and rod still snug on the crank - which is also nice and clean.  The top of the K361 piston is a bit dingered up but she fits snug in her block... am considering just tapping those back into place or filing off... not sure yet.

The balance gears will be a true pain the butt to get timed again in the K361 - but I'm all for the smoothening out of the vibrations - if the K361 shafts and gears are in good enough shape.

All for now.

Good day,

Pulled the K361 crank:

IMG_1550.JPG A pretty need fuel pump on this one with a primer are built right into the pump - am gonna like that to start it if sitting for a while.

IMG_1551.JPG

The pull went fairly well - the crank end didn't slide out the easiest but otherwise ok.  The balance gears are in and snug on there shafts - lots of particles from the camshaft explosion to clean up but don't want to pull the cam and governor... got my small compressor working all of the debris outta the block.

Printing the timing hints from the pulling website dude - nice clear pics:

A Kohler pub so should be good to add here or in the publication section... the moderator can edit this as needed.

Slowly and methodically - Brian.  wpgjetfan
