Hello I have a 1840 thats decided to stop raising the bucket. If your lucky it will raise about halfway slowly then stop. I just paid $300 for 10 oring kit from case installed it in control valve and no change. All looked good in control valve nothing scarred. Fluids good. Am I missing something else here? Thought I would ask before I have to spend the $2800 that the Case dealer here wants for a new one. Any help would be greatly appreciated. Thank you
