Posted by smittydog on May 02, 2013 at 11:58:01 from (188.8.131.52):
I inherited my fathers projects One of which is a Case 530 CK with 188 diesel engine. Dad had the injectors out about three years ago and never put them back in. He was also correcting valve timing. (note, the injector openings were left open-but the cover and a rubber mat were over the engine, so moisture could have made the rings stuck on the pistons)
So, this past few weeks, I have been going to farm and working on it. Had the starter rebuilt, replaced the solenoid and ran new wiring where needed, also replaced the ignition switch.
We verified the correct valve settings (per case manual), put the injectors back in with new seals, also blew out the fuel lines and put new fuel filter on. I bled the fuel line at the injector pump. We get fuel flow to that point. Now, with new battery and battery charger/starter, we are able to crank the engine over, but no luck. Very small, small puff of smoke, at one point acts like it wants to start, but no dice. We are using either (I know, it will blow a hole in the block if overused). My dad put in a small oil cup in the intake for just such cold weather starts, that you squirt the either in. His idea, not mine, but it has worked in the past.
Now, two things I didn't do...check compression and pull the injectors to verify that the fuel is going into cylinders ( I didn't have one). I now have a compression tester and adapter for 188 engine (long tube insert) so I can test compression in it this weekend. At that time I will also be able to check for fuel coming out of the injectors.
I would think that even if it was not getting fuel, it would have started briefly from the either. Correct? By the engine NOT developing compression, the engine can't start. So I am thinking that the rings are stuck or seated to the pistons? (since my dad never put anything in the injector holes for three years and moisture probably crept in and rusted the rings to the pistons)
I also want to spray in some SeaFoam Deep Creep or manifold cleaner to see if it will free the rings.
New to this diesel thing, but I got our Case 450 bulldozer going this past winter. (it also has the same engine, a 188 diesel).
Am I on the right track? Any other ideas or suggestions?
