idosubaru Posted June 5, 2010 Share Posted June 5, 2010 trying to disassemble a seized EJ25, down to the last two 12mm 12 point bolts before my socket cracked. i can't rotate the crank because it's seized so i can't remove the pistons to split the block. once all the bolts are out will i be able to separate the block just a bit to free the crank up and spin? how hard will it be to get the motor to budge a 1/4" or something with the pistons still in it? am i going to need to chain one end to a tree and chain the other end to my Kubota in order to split it? (please say yes!). Link to comment Share on other sites More sharing options...
davebugs Posted June 5, 2010 Share Posted June 5, 2010 No idea. But the world is littered with 2.5 blocks w/bad bearings. Why play with this particular one? I mean we all like a challange, but..... If you're up for a drive I can probably get you a long block with bad bearings (really bad but still ran a little) that I have stolen throttle body, sensors, etc from. A 97 w/180k. BTW I bought a gently used Kubota BX23. Everyone needs a little hoe! Small but effective if I take my time. Sure beats the method I was using prior to getting the machine. Haven't done any car "work" with it yet. Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 5, 2010 Share Posted June 5, 2010 If you do it make a video and put it on Youtube please!!!! Doesn't seem to me like it should be that bad, but it depends on the reason the motor seized in the first place I guess. Link to comment Share on other sites More sharing options...
idosubaru Posted June 5, 2010 Author Share Posted June 5, 2010 But the world is littered with 2.5 blocks w/bad bearings. Why play with this particular one. you're right normally i'd scrap it and i should have this time too. but i mainly wanted to salvage the torque converter still attached to it. i was thinking zip the bolts real quick and it wouldn't take long. wasn't planning on my only 12 point socket cracking. congrats on the kubota, not sure how you'll do but i'm sold for life. thing is awesome, can't believe i waited so long to get one, i just never knew any different. no carburetor is awesome, starts every time even after sitting for months. and it's all metric bolts so don't need new tools :lol: mine doesn't have a hoe - is yours for rent!??!

davebugs Posted June 5, 2010 Share Posted June 5, 2010 Hoe was mandatory. Hoe and front loader. 4x4, locking diff, etc. 450 hours now. Basically made crates for the car hauler so it didn't fall into the middle. Friends have pointed out more of my redneck qualities with my Kubota on the modified trailer. Hey, whatever it takes. Plan is to keep it until I'm done with this foreclosed house, another day in the mountains with it, and landscape around the pole building (finally) then sell it. Hopefully in the fall, or keep until spring when it may be more valuable. We'll see. I'm outta room, but nice to have around. I just hope to get all my work done with it then have no need for it. That's why I bought used. They are kinda hard to find decent used ones. Still wasn't cheap 6 years old w/424 hours on it. But the offer stands for the junk block. I think I've thrown out all my TC's.

idosubaru Posted June 5, 2010 Author Share Posted June 5, 2010 i'll be around the inwood/martinsburg area next week, you're not close to there at your new place are you? i'll be busy with wedding stuff, but could grab a coffee in the morning or something maybe to chill.

ShawnW Posted June 5, 2010 Share Posted June 5, 2010 Did the piston shatter that is on the seized rod? If so shatter it enough to get at it. If you can work the block to be open at the top or bottom like a V you can take the rods apart with a wrench one at a time till its not so frozen up. Done a lot of them unfortunately.

idosubaru Posted June 5, 2010 Author Share Posted June 5, 2010 Did the piston shatter that is on the seized rod? with heads removed the pistons looked like every other one i've pulled apart so i assume they're fine? Link to comment Share on other sites More sharing options...
idosubaru Posted June 8, 2010 Author Share Posted June 8, 2010 (edited) okay it worked. i thought i was going to be hosed since the flexplate is still holding the halves together and there's one more bolt underneath the flexplate that i forgot about. but i used a chisel and hammer to open the top and front of the block and it came open a good bit - 1/2" at least. when i started pounding the piston tops it SLOWLY started to walk and i got the TC bolts out. got my torque converter back. SCORE! Edited June 8, 2010 by grossgary Link to comment Share on other sites More sharing options...

idosubaru Posted June 8, 2010 Author Share Posted June 8, 2010 i thought about it just because i kind of wanted to tear it down and maybe see what was going on/what happened. but then thought better of it thanks goodness. are those actual numbers, i'll give it to a buddy of mine that doesn't have a job! oh - and when i removed the pan there was a rather nicely sized gob of sealant up in the screen for the sump/oil pump supply. headgaskets were replaced 20,000 miles ago on it, so who knows i guess it either overheated too bad or something got in the oil supply.

bheinen74 Posted June 8, 2010 Share Posted June 8, 2010 \ wasn't planning on my only 12 point socket cracking. \l: I stick to 6 pointers......its my secret and i am sticking to it anyhow, did you fix your socket yet. How was the flexplate holding the block together? It is only attached to the crank, not the block. Link to comment Share on other sites More sharing options...
idosubaru Posted June 8, 2010 Author Share Posted June 8, 2010 I stick to 6 pointers......its my secret and i am sticking to it.they must indeed be secret 6 point sockets if they fit 12 point bolts holding the block and heads! How was the flexplate holding the block together? It is only attached to the crank, not the block. yeah right, duh flexplate bolted to block, that's awesome. it was only the one bolt behind the flexplate holding it together. the splitting of the block with a hammer and chisel began to crack all around that one bolt though so it would have eventually just sheared off completely.

bheinen74 Posted June 8, 2010 Share Posted June 8, 2010 (edited) thats all clear now thanks what did you do with the boat anchor? did you bury it using the kubota i guess bolting the flexplate to the engine would seize it up if you wanted to do that. alright, done on this thread. glad you save a torque converter.

idosubaru Posted June 8, 2010 Author Share Posted June 8, 2010 dumping it in an XT6 headed to the scrap yard. i didn't even use the kubota, the block split easier than i thought it would. the pistons handled much solid wailing with a hammer. anywone want some pistons?!
