Massey 1855 to a 4855

That's what I used for my 1" dia. rear PTO shaft to engine coupling. Mine is made by Docap.

When all was done it looks like we will have to rebuild a couple of the fuel nozzles and give it another run.
Looking at this engine configuration it appears it will be quite a challenge to slide this puppy into the 4855. Bear with me I have not given up yet.
I'll throw some pics when I get back on Firefox.

How do I spell "impressive"? ducky
That is the look that I have envisioned for an articulated version of a MF1655/1855! Love it!!
For your hydro woes; turning the charge pump cover 180* reverses the input rotation, turning the motor section 180* changes the output rotation. There's no need to change anything internally.
You can use a lighter oil in your chaincase if you want to use this critter in cold weather. The high speed of the chain will sling the oil all over for lubing. Fill level is just below the lower shaft. Chains don't need much lube. My 35 year old snowblower uses the same thing for chaincases.
Thanks, Doug, for pointing out this thread. I would have missed it entirely!
Thanks for the get back you just saved me a bunch of work for nothing. I was going to pull the rear hydro an turn that swash plate. I would have really had to kick myself around the shop when I got that think open and not found a stop.
Thanks again Tudor

Let take a look inside.
Ok If we look at this pic it seems to me that that the pintle valve is stuck open.
Tell me if I am wrong but I think that the Valve (Little hat ) should sit done and seat of the nozzle end correct? I can not move the pintle that I have my index finger on and I believe the should move up during injection and back down to allow the hat to seat and terminate injection.
Just want to be sure before I screw thing up.

Diesels are definately the most neglected, no valve adjustments, no fuel filter changes, same injectors after 200k, oil never changed, esp on those older dirty engines

Those things look like they ran home brew bio-diesel through it... Yuck! Might need to send them out, they need to be perfect on those 'Benz diesels.
Yes they sure do not look like they got any high quality fuel. Being a spare and in such bad shape I am going to use this as a training tool. Not much to loose.

Well I have an update on the 4855 project. The drop case failed due to lack of lub so we have to remove it and rebuild it. Also upgrading to #50 roller chain due to the scheduled re power.
This is what we are going after.
The drive shaft you see comes from the engine.
First we remove the seat and its holder.
Then we go after the rear hydro drive cable, Rear drive shaft and the steer cylinders and related hydraulic lines.
Then there are 8 ea. 3/8" bolts that hold the dropcase into the frame.
Now the dropcase will slide back off of the front drives splined drive shaft. Do not have a pic of the front drive but it is the same as the stock hydro unit.
Then you have it on the bench.
This is what I found. Chain off sprocket and badly worn. What happened is I only tack welded the lower sprocket to the hub and it let go.
Took everything out of the drop case and picked up new bearings and and sprockets to upgrade to #50 chain.
Here it is with the lower shaft installed with the chain fitted. Then install the upper sprocket and slide the shaft into place.
Then we use RTV to seal the bearing housings and adjusting slots.
Then we installed it with some lub this time and we are good to go.

Had another issue with the drawbar mount. I originally had it hooked to the center pivot.
This did not allow the tractor to articulate the way it was suppose to. I machined up a bushing for the draw bar and shorten it and mounted it to the rear of the articulation point.
One more design issue solved. The drawbar came off of a 350 IH and is mounted on the 4855 to have clevis type drawbar common on the larger 4 wheel drive tractors
The iron holding the drawbar are there to incorporate a 3 point hitch down the road.

Ducky, It looks to me that you lost lubrication from all the shavings.

Good to see an update. Projects like these take a while to work out the kinks, but you have things in order now. When you get more HP bolted in there, multiple plows will be a piece of cake!
