It's probably a wobble pump and doing what it's supposed to do. :bigrofl:

Sorry, I couldn't resist. I hope the rest of your week goes better.

Gonna attempt hauling manure tomorrow, being the pit is almost full, and we have one field just dry enough. Just hope we have no problems with this task. More rain coming Wednesday. No time to mend broken stuff right now. We have enough tractors to lose 2 or 3 & still get by.

Daniel, This is the tank I told you, you could have. It measures 25" X 20" X 10.5". Here are a couple pictures of it..

You can cut it down however you need it.


That would make a heck of a tank, once cut down to size a bit. Looks stout!

Well, good news & bad news......the bad: the repower is on hold. The good: the Onan is purring again. Had a wiring & carb issue strike at the same time. I really don't have time to get into the repower at the moment, and would like to get a radiator mount built ahead of time, as well as a few other things, so that when I do start the conversion, it will go easier with the smalls already dealt with.

Sounds like a good plan, Daniel. Glad you got the Onan running well again.

The Onan was having issues with this stuff they call gasoline again, I think mostly vapor locking as it did before.  But the time has come to take the burden of gasoline & all it's inherent problems these days off my back & put in my Yanmar 3TN66, a 16hp 3 cylinder into the Massey.  So it will return to it's OE life as a 1655, but better!  She'll be a MF1655D when completed.  

  The funny part was when I went out after lunch to find Dad wrenching on my Massey!  It was raining & he was bored.  I had told him I'd taken the loader off to swap engines.  The Onan was running decent & I had intended to drive it to the milk parlor to blast it clean with hot water, but I can still do it, only have to pull her down there.  I hate working on filthy dirty stuff.  I took over & got the engine off and the battery & fuel tank trays cut off.  I want plenty of room to instal the engine, and whatever is left I can then decide what will or won't go back in that area.  I know for sure the fuel tank won't go back in, and there may be room for fashioning a new battery tray, but for a GT size battery sitting sideways.  I'll get the 420 amp GT version though.

I think I can leave the hydraulic pump exactly where it is & just mount the engine to align.

Here's the Yanmar 3TN66 that I bought from david (aka BairleaFarm) maybe 2+ years ago.  I think John Deere called the Gator it came out of as `18hp, but I converted the 11.3kw figure on it's tag and that makes it a 16hp, which is plenty of power, and way more torque than I had with the 18hp Onan.

Liable to be a few weeks till completed unless it rains a lot.

It's my day off tomorrow, but Teresa & I will be away most of the day.  When we get home, I may pull it to the barn & clean it up, but that'll be about it.  Been down to the shop with a tape measure doing some general checks, and looks like it'll fit in there real nice.  I hope to retain the rubber engine mounts, but may have to go solid if it's too tight due to the rubber isolators being kind of wide.  I have a driveshaft off an MF14 which looks like it'll need shortened about an inch, which is better than stretching.  It's a simple job of cutting to length part way down the tube, then slipping in a solid pin that fits snug to align & strengthen the joint, then welding up.  I've already machined a crankshaft adapter for the driveshaft to bolt to the engine.

The radiator is a boxed affair that will require building a steel frame & lining with rubber to protect it.  If I have trouble with this radiator, I'll switch to a std type.  But the electric fan works after taking it apart (not made to take apart) and repairing a broken wire, so it'll have to do for now.  There should be plenty of room for a battery tray in front of the dash once all the engine fitting is finished.  I will mount a fuel tank behind the seat above the rear weights.

Glad to see you have a good start on the conversion. It will be a whole different loader/tractor when you get it finished.

I still find it funny & a compliment that Dad was down there working on one of my GT's.  But then he's seen countless times what great work this little tractor can do with the FEL.  It cleaned 14 calf stalls & a section of the group calf pens just yesterday, and done the old way, with pitchfork & sore back, it would have taken at least 3 whole days!  And then my back would have been shot as well.  Wish I'd had a camera to take a pic of Dad working on it!  He'll be tinkering on it some more I'm sure, so I'll keep a camera handy!

Edited the title as the project has officially begun!  Used to read "Possible MF1855 Diesel Conversion".

Yes, I think it's great that he sees how valuable it is and wants to get it up and running. :thumbs:
