Daniel, This sounds like a great project. With the planned re-power of the 4855 I am considering a similar project. I think I can have a very well powered 2 wheel and use the larger motor where it will will be needed. In the 4855.

I kinda figured you'd be upgrading the powerplant in the 4855, but you had to use what you had at the time. With a larger diesel in that thing, it's gonna be a monster worker!

Would one of you enlighten me as to what a 4855 would be? Is that the articulated one that ducky built? Now if you two keep building bigger and bigger tractors we are going to have to move you over to the CUT forum :smilewink:

Yep, that be the articulated Massey! I'm just repowering, not building. I'm gonna leave that to ducky!

I have a 3 cyl Kubota diesel in a 1655 so leave me know if you need any pics or ideas for your build.I didn't do the conversion,I did it the easy way and bought it this way.It also has power steering.

I remember the pics of your tractor. Nice repower job someone did! I will be going for function, with looks secondary.

For what it's worth, in my opinion either the MF 1655/1855 are SCUTs, or the MF GC2310 is a GT. I have both and there's not really that much differance in capability for loader work. The GC is a little faster and sips fuel and the 1655 will lift heavier payloads.

Fuel consumption between them favours the diesel by a wide margin. The 1655 (actually 2055) will burn a 3 gal. tank in 3 - 4 hours doing snow removal and the GC will drain it's 4.5 gal. tank in 8 - 10 hours doing the same job.

The weak point on the 1655 front axle is the kingpin knuckles on the ends of the axle. I've broken both of them off, the right one twice. There's now enough bubble gum applied that even a 1400 lb lift doesn't hurt them. The spindles themselves are fine after 2500 hours of abuse. Has anyone heard of even a 3/4" spindle breaking or bending? I know that the ones on my MF12H survived the same loader that is now on the 1655 for 700 hours with no spindle problems. The amount of counter weight that can be applied to tractors with 3/4" spindles is limited by the lighter rear ends, so they can not lift as much as the heavier tractors in the first place.

Daniel, there is no stop for the swash plate in my Sunstrand. It has full deflection in both directions. The limiter for reverse speed is in the pedal linkage movement. It does no good to flip the swash plate, the machined surfaces are symetrical. I just checked my spare.

Yes Bob, my 2 pumps on my bench both have full deflection both ways. Still not time to do my6 conversion, especially since I need to clean the entire calf barn as soon as I can, so can't take the loader tractor out of service.
As to 3/4" spindles, yes, I've broken 2 of them when my loader was on my modified MF1650. I ended up reaming the axle beam & installing 1" spindles....problem solved. I do work that loader hard, and it shows by my breaking spindles. But the loader is on the 55 series now, and the front end handles it well.

Here are some fuel usage numbers for some John Deere tractors.The Yanmar diesels are the 330,332,430 and 455.Those extra HP on the 455 sure do increase the fuel usage.

The conversion may be getting close. I was just using my Massey loader to clean under the bull calf hutches, and all of a sudden she just died. No spark. I just put a brand new coil on this between 1 & 2 years ago. May be a points issue, but either way, it makes me want that diesel in there! Came in for a cup of coffeE to chill a minute, then drag tools down to see what's up. :wallbanging:

Gets better......while going with 4 wheeler & chain to pull the Massey to the shop, my son is walking from the cow lot where he was scraping manure. An almost brand new rear tire blew it's inside sidewall out! At least a 5" long split. When it rains, it pours!

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.

It never ends....just feeding silage. As I walked by the Massey 285 on the mixer wagon, I thought to myself..."Did I see that fan pulley wobble?" So when I parked it, I checked, and sure enough, the water pump bearings are going out! Dang, Dang, double-dang!
And Chris.....I'd end up shooting someone if I moved to town! LOL

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

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