Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Ive got a 67 d12 series 3 that im have troubles with. Wondering if anybody has experienced low hydrolic pressure to the 3 pt and rear outlets. At 1600 rpm im only getting 1100 psi of hydrolic pressure at the outlets and 3 pt makeing it difficult to lift implements. Wondering if anybody can lead me in the right direction as to what the problem could be. I have tried adjusting the inlet releif velve on the spool velve with no change and also tried a different hydrolic pump with same resaults. My other series 3 has 1850 psi at an idol so im running out of options. Any help is greatly appreciated thanks

	Does the PTO run an implement like a mower OK? Any unusual noise in the clutch area?
