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.
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.
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.
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.
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???
