Well, I got the blown Kohler KT19 out of my Ariens GT19 tractor tonight.  I'm not sure where the hole is in it, but it leaked oil all over my trailer from above the starter...

So, here's some before pictures...

and the tractor sans engine:

Looks like I need to find a fan for it--OEM is probably NLA, so maybe one for a Case 444 hydraulic cooler will work...

I plan to put a Ruggerini RD200 2 cylinder air cooled diesel in it if it will fit. Lombardini bought out Ruggerini and still uses their designs in some of L's tractors (and the Kohler/Lombardinis as well).

Here's the back of the engine compartment, with the drive shaft flange and Ross steering gear box:

Here's the distance from the driveshaft flange to the middle of the first pulley on the idler (electric clutch has two pulleys on it) Note the rear engine mounting holes are keyholed... I wish the front ones were--they're right above the front axle--in both cases you have to put a wrench through a slot in the frame to hold the top of the bolt while you unscrew the nut underneath.

 

Ariens GT19 Engine Compt Length.jpg

 

Here's the length of the engine from the back to the edge of the blower housing. There's a round 7 3/4" inch diameter by 1 1/2 inch round extension to the blower housing past that.The stub end of the crankshaft extends 1 1/4" further to the rear of the engine.

 

Ariens GT19 Ruggerini Length.jpg

 

The engine is 12 3/4 inches at the widest part of the blower housing; the block is 9 inches wide at the rear (which would face forward on this install) and 10 inches wide at the front--due to some tabs on the sides of the block.

 

The inside of the frame measures........ 12 3/4 inches.

 

Ariens GT19 Engine Compt Width.jpg

 

The Ariens GT18D engine had a Ruggerini RD180 in it--same block, same crank, same heads, same external dimensions as my RD200, just a smaller bore... HOWEVER, it has a 4 inch longer wheelbase.  Also, the dash support has filters on either side of it for the air intake for the engine... that's probably doable on this machine.  Fortunately the bottom screen is still intact as well...

So, do you think it will fit????

I have an 18 hp B&S Flat Twin that I may put in it temporarily to make sure the hydro works okay... though the PO said he was driving it up the ramp to his trailer when the engine blew.

 

IMG_20150130_172704_846.jpg

 

I need to get Pager450 over to lay another set of eyes on it and see what he thinks... he just shoehorned a 3 cylinder Mitsubishi L3E engine into a JD 400 tractor... this should be a piece of cake, right???

How's the height comparison?

Smitty, that Ariens looks to be in pretty nice shape. Does it have the Dana rear end. The Dana back cover looks like a big round pumpkin on the back side. Some of the Ariens have them.

Smitty, looks like it will be close, but  Ithink we can squeeze it on in.  I need to head over there and take a look.  Hows the rotation on it?

 

Id be happy to help you out any time

The diesel is about 4" higher than the gas engine, but the frame is relieved and gusseted so the engine sits low in the frame...

I measured it once, but forgot what it was, but there's room height wise...

My biggest concern is the blower housing--the engine is installed with the fan to the rear...

Yes it has the Dana axle--big aluminum pumpkin--I have a Toro mower with the same axle.

Thanks, Ryan, I figured between the 2 of us we could figure it out. You can come by anytime it's convenient--I get home about 5, and have an hour or so before my evening commitments this week--

The engine will have to go in backwards a'la your JD400. I've got it sitting at the end of my driveway, the engine is on a furniture dolly next to the gate to my backyard.

Okay, so I got my engine hoist out--pulled the skid from under the Ruggerini diesel, pulled off the blower housing,IMG_20150207_103314_564.jpg

 

then hoisted it so I could set it down into the Ariens frame.  IMG_20150207_102727_262.jpg     Will it fit??? 

One of my concerns is the steering gear box (the vertical silver cylinder under the dash) would be right up against the fan housing.

IMG_20150207_103941_888.jpg  

 

The crankshaft centerline on the diesel is about 1" higher than the Kohler KT19...The driveline (seen on the right side of the console in the picture below) just has a couple of flex disks on each end... would probably need a couple universal joints.

IMG_20150207_104305_661.jpg

 

Actually, it sets down in pretty good,  IMG_20150207_105327_869.jpg IMG_20150207_105314_582.jpg IMG_20150207_105417_044.jpg

 

except....  IMG_20150207_105303_508.jpg

I could probably remote mount the oil filter... it takes the same filter as many Briggs & Stratton and Kohler engines with pressure lube systems.

 

IMG_20150207_111059_805.jpg

 

                                                               IMG_20150207_110934_159.jpg

 

I would need to notch a little of the front grill support and the hood for the exhaust manifold, unless I had a custom header built.

 

The hood will fit fine on the left side, though.

IMG_20150207_111223_495.jpg

 

I'm thinking this might fit better in my Case 444... and I'll put my Mitsubishi L3E in here... there's more room in the front of the hood, above the idler pulley at pivot shaft, for a radiator.  The engine will have to be put in backwards, like Pager 450 did on his JD400, but I don't think that's unsolvable.  My Ariens GT19 is about the same width as the JD400, but the hood is higher--leaves more room to work with.

 

I'll just have to get Pager over here to give me his expert opinion--seeing as he has sucessfully repowered a tractor with a diesel, and I haven't.

So is the Lombardini 10LD400-2 in my 920 a relative of the old Ruggrinni design or an original Lombardini design?  It does closely resemble your engine.  I think that diesel would look good in that old Ariens, and IMHO it has more room under the hood than the Case 444.  I put a 10hp air cooled single cylinder diesel into a 444 and it was a tight fit.  Cant wait to see what you do end up doing.   Mike

The starter and carb are good--sheet metal, manifolds, too. I think they may fit the twin Magnums... PM me with what parts you need.

I'm pretty sufe your engine is a Ruggerini design. The diesel Ariens had a stretched frame--4 inches longer... would rather not stretch it if I can help it.
