Morning all!
I've inherited a problem, following a clutch change by someone else on a Case IH 485, year 1987.
The tractor is located a a local livery yard, and following the clutch change it seems that the hydraulics to the front end loader and the 3 point linkage are not working.
The power steering works fine, and the priority valve is free.
I could do with identifying a valveblock just after the filter/pump/priority valve/relief valve. This valveblock appears to be operated by an 8mm? steel pipe to a slave cylinder with bleed nipple. I have no idea what this valveblock does or how it is operated! (the input from the pump does have free flow when cracked)
The second thing I could do with knowing, is which levers and in which order do I need to pull them to get the 3 point linkage to lift. Wherever I set them, there is no movement on the 3 point lift.
The front end loader is controlled by a pair of cable operated valveblocks located on the right side of the engine. The supply /return pipework derives from above the transmission somewhere and must have been disconnected for the clutch works. No pressurised fluid loss from either when cracked, just a small dribble from one of them.
I will attach a picture of the slave operated valve, in the hope someone can tell me what it is or how it is operated, and I'll attach other pictures of the levers inside the cab.
Cheers in anticipation!
Neil.
