I am about to do that with mine. I don’t have any of the original engine bay tins though so I don’t know how that would would work out, thinking most of them are not needed. For the exhaust I’ll make a new set of factory type pipes to hook to the stock muffler to the newer engine. Let me know I can always build a couple sets. The pump is not the same size so you might need some bracket fixing there.

No, unfortunately I don't have a paper pattern, (typically flew by seat of pants) I would have drawn that on a flat square plate, drilled the holes to match to the tractor frame, I then would have left that plate on the tractor frame and over top the plate, stuck my motor onto is,, I would have positioned the motor, clutch end, centered to where a v belt would in theory come down to say mount a mower,, once centered to that, squared to tractor frame, I marked the motor mount holes. Now, having 8 holes in that square plate, I just shaped the plate in the above picture, making it kind of pretty,, I subsequently, elongated the 4 motor mount holes, so I could slide the motor further back by roughly 3/8 inch,,
The motor adapter plate is easy to do, the more difficult part is to match to a decent exhaust. What I did start with was,, I did have an old 646 OEM muffler. From there, I ended up purchasing 2 pipes off a 6018? and a tiny bit smaller 3 ft strait OD pipe, (bought new, from online source, I needed this to join the 4 pieces of pipes together,, )(3" piece of smaller OD pipe, inside 2 pieces of pipes,) welded it all up together and called it done.
Above, I mentioned is 3/8 plate, it was a 1/4" plate.
Have a browse through this thread,, in there, you can see my trials and tribulations,,,
Just skip to the parts of motor and pipes,, and whatever else you might prefer,, Exhaust, honestly turned out OEM looking, and not as much as a challenge as I originally thought. You have a pump mount? if not, you can see how I did mine,,
Any reason you didn’t just bolt the motor to the frame?No, unfortunately I don't have a paper pattern, (typically flew by seat of pants) I would have drawn that on a flat square plate, drilled the holes to match to the tractor frame, I then would have left that plate on the tractor frame and over top the plate, stuck my motor onto is,, I would have positioned the motor, clutch end, centered to where a v belt would in theory come down to say mount a mower,, once centered to that, squared to tractor frame, I marked the motor mount holes.

Lionel, Thanks, I am trying to have as much in order as possible b4 I begin this swap as I use this machine frequently and want to have as little down time as possible. I will review the thread as I am sure there is valuable information in it for me.

So,
This is a bit difficult to explain, hopefully a partial view with pictures will help,,
So, for starters, I did not have a pump mount to start with. I made my own using a standard pump mount off a 446. and I orientated the pump, coming out from the motor so that the fittings going in and out the pump sat horizontally. The high pressure line coming from the pump, which went to the rear PTO valve on mine, had a pretty bad kink in the line, approx sitting above the holding valve, (corner of tube, where it travels from left side to right side of frame).
I took that tube to a hydraulic shop. We cut the front part of the tube, from the middle section viewed in this picture, (you can see where the hydr hose connects to the hard tube line,) The shop flared the hard line for me. So, the front piece of the tube, was thrown off, and a partial hard line remained, which was connected to the pump high pressure fitting.

As far as the inlet to the pump,, that's relatively low pressure, so I used a piece of tube off a 446,
From tank, piece of hose, to a piece of tube that went beside the motor, and to connect it back up to pump,
A piece of hose again, and slipped it over a fitting that I'd mounted on the pump. Special hose clamps,, and called it done.
All hoses, and hose clamps came from the same hydraulic shop. (They were like 5 minutes from me, so that was very convenient)
