When you replace a hydraulic hose are you supposed to bleed the ram/hose ? If so whats the procedure ?

On my 1967 JD350 theres a pin on the top of the hydraulic reservoir that sticks
up when the engine is running - I remember seeing a post about this but cant remember what it is - maybe the hydraulic pressure relief / filter bypass doo-dah?

If it is - should it be up and go down when
I put load on (thats what happens) - or should it just be down and only go up if the filters in the hydraulic reservoir are blocked ?

Cheers

Andy

I had one of those on a JD 450 that jiggled up and down a bit too many times. One cold winter day here in Alaska way the heck out on a Power Line job it just blew right out and the hyd. oil followed and hit the canopy and showered me in good shape. Nothing like being drenched with Hy Guard on a winters day.

If the temperature is below 40-50 degrees F, that filter restriction indicator will go up and down until the oil gets hot - even if the filter is clean. Deere had problems with it and jerked around for a while with filters of different micron ratings. Finally, Deere recommended that you use "winter grade" hydraulic oil if the indicator keeps jumping around during colder weather startups. If you wind up pulling the top cover off your hydraulic revservoir - #1 be sure the spacer is inside the filter that the long bolt goes through. If it's not, it almost impossible to keep the bolt tight enough to keep the filter on. That spacer tends to get lost. #2 - many 350s have a second filter on the bottom of the tank that is held in by a spring loaded clip. You can't see it since it's under the oil. Just stick you hand down to the bottom and feel for it.

All hydraulics are self bleeding. Fill the reservoir, cycle the hydraulics , refill reservoir. That little pin that pops up is a filter relief valve. Remove the top cover , There you will find a filter hanging from top cover. There are 2 styles . One with a cover on one end with only a hole for thru bolt. The other is a filter shell without an end cover. When that filter relief valve goes off , it's telling you either your oil is too thick or filter is plugged. Do your self a favor, when you have that top cover off, change the small roll pin that keeps that relief valve from falling thru incase it breaks, [ which they do often ]
