Here is the latest update on my 955 12A project… where I try to free up the diesel that may have seized due to little or no oil pressure. Currently, the pony motor will hardly even move the diesel due to it being tight. I tried to feed it some oil using a “pipe bomb” device – party filled with oil and 40PSI of air on it – plumbed in to the header pipe where the oil gage connects. It made no difference. So, today I dropped the belly pans and got ready to drain the oil. Next I’ll remove the inspection covers on both sides of the oil pan to see if there is a sign of bearing (rods & mains) problem. I have been told that the first to fail are the rod bearings. None the less – there is a very good possibly that the pan will have to come off / down.
Please review my sequence for pan removal if you would:
1) Remove the 6 large bolts (3 each side) that connect the cross axle to the engine structure.
2) Remove the center pivot pin that connects the engine to the cross axle.
3) Jack the engine / entire tractor up (pivoting about the finals drives) and place blocks under the cross axle & engine structure connection point to hold the engine upward – probably 8”.
4) At this point I should be able to remove the oil pan and get it down out onto the ground.
5) All the while be on the look-out for another GOOD 955 12A that could be my main tractor – with the one I am working on being a parts tractor.
Has any one ever gotten into one of these machines this far?!?! My thought is that if the rod bearings (and / or main bearings) got tight from lack of oil - I can polish the crank-up and replace the bearing inserts and have a usable machine. The hope is the cam & pistons etc. haven’t sustained damage. So there you have it for today. And if you can… review my above methods please.
