Do I have a seized engine? (GM Detroit Diesel 2-53)I bought a non-running John Deere 440 ICD crawler loader. It was said to have last run last fall. The guy I bought it from had removed the blower for rebuilding. I took the blower to a repair shop, and the mechanics there said the blower bushings were worn, and they repaired the blower. I installed the blower, and went to start it. Tranny in neutral, foot on the clutch: the starter motor gear didn't sound as if it was engaging. The battery cables were in poor condition, I replaced them with 00 guage cables. While doing this, I removed the starter to ensure that it turns fast and freely when connected to jumper cables. Now, with the starter installed, the starter motor gear engages, but the engine barely turns. So, I figure one or more of following is true:
1 - I am a chump, and the guy I bought the machine from gave a great sales pitch.
2 - Liquid of unknown origin has seeped into the cylinders, are prevents engine rotation.
3 - The hydraulic pump at the front of the engine has seized.
4 - The starter is faulty, though I can not imagine how.
5 - The clutch/tranny is faulty, though I can not imagine how.
6 - The engine itself is mechanically seized. What should I do now:
If I removed the hydraulic pump, would the engine rotate with a breaker bar and appropriate socket over the splined shaft at the engine front? (Where do I get the socket?)
Remove the head and inspect?
Remove the air box plate adjacent to the governor and inspect?
Remove the engine, and rebuild/replace?
Put the machine on Ebay? So a couple other questions:
What does a used GM 2-53 cost?
What does a rebuilt GM 2-53 cost?
What does it cost to rebuild my GM 2-53?
I wish I was crawling!
