Need some suggestions

Did the hydraulic hose to the loader become disconnected? It will be hard to turn over with the hydraulic dead heading.

Will have time to mess with things a little bit later today. I haven't checked any QD's yet but will later today. I did move the joystick and 3PT hitch control levers around in an attempt to relieve any hydraulic pressure on the system. Thank you for bringing this up Len. You got me a rod when my son hydrolocked this same engine by taking it for a swim in the pond 4-5 yrs ago, but I pray to God you're not getting me new parts for a major overhaul soon. I don't mind throwing you business from time to time but I always thought this issue would be at least 1500 hrs later than this.

Took valve cover off and push rods don't appear bent, valves can be pushed by stems freely and everything else looks right. Dropped oil pan and from the limited amount that I can see of:

Cam and lobes- appears OK
Rods/pistons/cylinder walls-appears OK
Crank-appears OK

Loosened the 4 crankshaft bearing caps thinking that if bearings were seized this might possibly allow me to turn crank by hand- crank still wont budge.

Haven't taken head off because I still want to try the easy stuff and I suspect a new head gasket is going to be pricey and might be hard to get.

I guess next thing will be to take timing cover off and make sure gears are OK and take hydro pump off and make sure it hasn't somehow imploded. I did post in parts and repair forum for a little more detailed explanation of what I've done. Hopefully I'll get a few more hits and more advice on the easy stuff.

You could try loosening the rod caps too, at this point. I don't know of anything else that could reasonably be at fault. If the transmission is free, it's the not the flywheel side bound up. If the glow plugs have been removed, there is not incompressible liquid locking up the cylinders. If the hydraulic pump is free, it isn't binding there.

The remaining suspects seem to be the rod bearings and/or reciprocating parts, or the gears on the camshaft. If it's easy, check the cam gears. If it were mine, at this point I'd just pull the rod caps and, with a wooden dowel, see if I could drive each piston up any in the cylinder. Once all three were free, the crankshaft either has to turn, or is the culprit.

Stupid thought, here, but there isn't possibly a belt-drive accessory seized up like the alternator or water pump? And the belt isn't slipping?

Haven't had time to get back out in the shop due to work schedule. I've gotten some good advice here at TBN. I think I'll be doing exactly what you suggested, as well as checking crank and rod end play. I think between taking the timing cover off to check the gears, seeing if there is any end play in crank and rods and trying to move the pistons in the bores, I'll be able to figure out what the problem is without having to remove the head..... of course depending upon what I find, I may be removing the head anyway. Hope to have it figured out by this weekend at latest.

I've ruled out those possibilities and unfortunately it appears to be a bigger issue.

I had a generator that was running fine, shut it off and then it seemed froze up. Turnrd out to be carbon build up in the head. Cleaned it out and it ran fine. The long idling period makes me suspicious. if nothing else it's easy to pull the head.

Diesels will run at idle forever and never get ruined unlike a gas engine.

I posted this in parts and repair too. Finally got in garage today and first I checked the crank for end play and it was good. Checked rods for lateral play and #1 and #2 were fine, get to #3 and doesn't budge regardless of how I try. The piston was sitting right at TDC so I felt forced to pull the head. Got it off and with some persuasion was able to get the rod cap off then knock #3 piston up and out of the top and presto...crank spins free. You can see that there was a heat issue. I haven't seen 360* on the journal yet but I didn't see any gouging....just bluing from heat. Not sure why this end wasn't getting oil? I am surprised after seeing this as there is no question that this was the issue but wouldn't have thought that it could seize.....and remain seized without more signs of damage. What course of action is advised from here?

Well, It's been a long time since I posted about this and thought I'd put this one to bed. Projects move slowly around here....I worked approx. 1700 hrs. of O.T. last year ( 2012) and '13 is on that same track. Add in family time, church, rental business etc. and the tractor comes way down my to-do list.

Turned out that a rod bearing had spun. Sometime early in '12 I had the crank turned....... and everything sat idle.

In Oct '12 I had a little vacation time to use, so....I went through the entire engine. Although they looked pretty good, I reground the valves and seats and put in new stem seals, put a fresh crosshatch on the cylinders, installed new rings, obviously put in new crank and rod bearings and buttoned it up with new gaskets. Test fired it...... and everything sat idle.

In march '13 I took an afternoon and put the engine in frame....and there it sat.

Two weeks ago, I decided enough was enough. I put the halves back together, put the loader back on, solder a hole in the radiator and was finally "finished", only to discover it ran like crap! It didn't start easy, seemed to have about 75% power at WOT and sputtered/cut out some. I was bummed. After several hours of running, I decided it could be the fuel but was doubtful since I've heard a million stories about people using much older diesel than the 18 month old stuff in my tank. I drained the tank, cleaned the sediment bowl and filled it with fresh diesel...... she fired off immediately and runs awesome! We've since put about 5-6 hrs on it and she truly runs/starts better than I ever remember since I've owned it ( ten years/800 hrs).
