Bought this HD-12 from member sascr (Scott) with intent to put in a Perkins/Shibaura twin cylinder 13.7hp diesel.  Had the tractor since 9/21 and hadn't gotten to start on anything till I took a little time for it yesterday.  Below is a pic while still at Scott's place.  Seat pan is off in the pic.

 I have the motor mounts built in 2 pieces for each side to help align everything for a good fit.  When I get the time, I'll roll it to the shop & weld the 2 haves together on each side.  

  I will use this fuel tank behind the engine.  It should run it a long time on a fill up for sure!  Tank came from my Massey 1655 when I repowered it & wasn't room for this large tank.

  I may also have to make a cutout in the frame side to allow oil filter changes.  I haven't checked, but there "may" be room for the filter to screw off without making the cut.

There is plenty room for the radiator.  Not made up my mind if I will use a fan on the engine, or the electric unit that came with the new radiator.  If I go with fan, I'll have to fit another to the engine, as the fans that come with these engines are "pusher" fans, and I'll need a "puller".  If I used my current fan, then there's a danger of the fan sending something into the easy to damage aluminum radiator.  Plus I couldn't add a screen to keep crud out of the radiator cores.  If I go electric, I may have it pull from the front, helping keep heat off the driver.  I would have plenty room for a screen between the radiator & engine.

Below is a copy of Scott's post when he first bought this HD-12.  True to his word, he gave me first dibs!  Thanks buddy!  :thumbs:

Daniel I did think about you when I found this one, but when I saw the grill, rear pto, and that good tail light, (and I did not have any of those items), I decided I better keep this one. But I am still on the hunt for the next one. :-) since the first one I bought came from Kentucky, I had already decided if I found one your way that I did not want, you should have first dibs on it. (Plus you restoration of the D4-10 was the starting point for me collecting bush hogs)

That looks at home in there, Daniel! Nice fuel tank, too! Just a thought. You say these came with a pusher fan. Put a screen between it and the radiator that you can remove easily to clean when you open the hood. Might build some other screened pieces to go along the outside of the fan area to keep something from getting in there to break a blade off!

With a smaller fuel tank, one could easily fit a smaller 3 cylinder in there with no problem.  I forgot to mention, the battery tray was where this fuel tank is sitting.  I will have enough room in the rear to place a GT size battery.  It will fit close to the rear of the hydro pump, and extend just past the back of the frame rails.  There is no back panel, so I'll fab one to come behind & around the battery, then bolt to the frame rails.  Everything I do, I am trying to make so it can fairly easily be put back to OE if ever desired.

After feeding silage, I rolled the HD down to the farm shop & got the motor mount halves welded together.  Likely that will be it for a few days with dad's surgery tomorrow & all.  But it's a start!  Now that that is welded, the next step will be to pull the engine back out to remove & finish welding the motor mounts, and adding gusseting to them.

Can you use a remote oil filter instead of cutting the frame?

That would solve the issue, but I'd have to make the remote adapter.  Would take some time to figure out how, then to do.  I've got plenty of time to figure out which way I want to go.  If I did cut, I planned to add a plate to strengthen the cutout area.

It earned the spot, as it lifted the engine into the HD-12.   :D

Almost zero time for myself, but I did steal an hour just before this post and got the reinforcement welded into the engine mounts.  Mounts are bolted to engine & lowered back into frame.  All the time I have for now.
