   Your going to love the Yanmar. The ones I have start much easier than the Kubota's I have and are much quieter and smoother. You should be OK without the rubber mounts if you can't use them. I've seen applications where they are mounted solid and seem to hold up just fine. 

  Enjoy your day off with the wife.

What are you intentions for the Onan? I have an FF that needs one!

This will be a sweet GT when you are done with this!

Not really sure yet, but whatever I do, I need to give it a good tuneup.  There was a LOT of vibration due to the driveshaft, so that was likely causing a lot of issues, and when I say vibes, I mean huge shaking of the engine.  I thought of getting it in top shape & selling, as this has the large crankshaft output as it came out of an earlier JD318.  Doesn't burn any oil as I rebuilt it before putting it on this Massey.  Gotta change out the oil pan as one of the feet are broken, but I had a bolted on steel foot to take it's place.  I already have another oil pan for it.  40psi oil pressure when cold, 15psi when hot at slow idle.  I could have replaced the driveshaft & left it in the Massey, but why when I have a diesel waiting!  :thumbs:

Yep, quicker starters for sure except for my Kubota D1005 as it starts equally well!  This will be my 3rd Yanny as I have the JD935 & JD340 both with 3TN72 diesels and I love em!   I am trying to get away from gas for all my "worker GT's".  The 2 JD's are my mowing machines, my Bush Hog JB diesel is my plowing tractor, and this Massey FEL tractor will be diesel as well.  The Bush Hog diesel will end up with added rear pto so it can serve as my tilling tractor also.  I am going to attempt building my own reversing gearbox for my rear pto on it.  Already got a set of gears, bearings, and seals.  Just need to round up some more 1" shafting.  Also have thick plate and heavy wall round tube to hold the bearings & seals.  Just a matter of having time to start that.  Diesel is SO much more dependable, and with limited time for problems, diesel all the way for me except for my collecting side.

Me too. I have the CC dumpster to do yet and the golf cart. Then I think I'm just going to enjoy them, as if I'm not doing that now  :D

Just trying to figure exactly where I want the engine.  The stub that came with this engine is long enough to bolt the pulley that drives the hydraulics right onto it, but I think I'd rather scoot the engine rearward.  That would require making a short stub extension, which would be easy enough, so I think I'll go that route.  The stock engine mount ears aren't in a good place to use the rubber stock mounts from the Gator, so looks like I'll go with solid bolt mounts, which I don't think will matter that much.  These 3 cylinders run so smooth there isn't much vibe or shake.

It's looking like I'll have room for an automotive battery & the air cleaner unit in front of the dash.  My current auto size battery is too large though, so I'll have to buy a new smaller size.  I can use the current battery in my dozer as it's battery went south a while back.  Will have to build a new battery box, and the air filter unit will also bolt to it's side.  I won't start the battery box until I get the engine mounts done & engine bolted in it's permanent place.  I'll have to build a fuel tank to sit either behind the seat or under the seat where the toolbox is now.  Under the seat may not hold enough fuel, so I'll have to take some measurements to see.

I'm sure you'll find the right spot for that engine, they usually set just in front of the dash and behind the grille!

No, not quite 2 years.  I dug out the pics when it was still in my truck July 29th 2011.

Got the motor mounts built & engine bolted solid.  Hooked up the wiring harness, dropped the fuel lines into a jug of diesel.....she fired right up!  :dancingbanana:  

Now to see if the radiator I have can be fitted well.  If not, I'll have to buy a new one.  This one is 4" thick + 3" for the fan sticking out, which isn't a good thing.  The one Mike linked to in another thread would likely only be 3 1/2" thick with the fan mounted, 4" max.  That would cut out 3" of extension to the front of my tractor.
