Troubleshooting left track clutch on my dozer

[Bull's EYE]

My dozer has 1400 hours, and the left track won't disengage. I removed the hydraulic solenoid and clutch fork, fork moves about 3/8 inch. Can the clutch still be locked? Can I rotate the sprocket to free it? Any tips on solenoid push length or freeing the pressure plate?

Oh no. Be really careful rotating the sprocket without fully understanding the lockup. Maybe double-check the solenoid push and try tapping the pressure plate gently to see if you can free it or something.
