Hi guys,the PD clutch seems to be slipping in both Hi & Low range @ low rpm. If I rev the engine up to 800 - 1000 rpm it works ok. I&T book says to check pressure at 2000 rpm & it should be 290 psi. What pressure should it be @ idle. And can I check psi with gauge @ either A or B socket head plugs on the pto control valve showen in pic. Thanks Dave. |

| Regulating valve in the PD valve is stuck, remove and polish up and I bet it won't slip any more. You can check pressure at those ports. |
