300U: Hyd filter?

redtom · Dec 4, 2014

Is there only the screen in the top cover under the seat? Or is there another hyd filter? I just want to get the hyd fluids changed so I can send this one down the road.

That should be the only one,becareful lifting on the seatframe/hydtank,its awkward and heavy...
have you priced a new screen,recently???? YIPES!!!!

It is made of bronze. You can fix the old one if you have a little tallent and it is not crushed too bad. You should see when somebody wraps all of the pipe fittings with that new fangled tefelon tape.!! The filter looked like it had been run over by a tank!

I'm way off on this one. Isn't the top cover/hyd all part of the rear end sump? I'm draining rear end and that aint hyd oil. I thought it was all one common sump like a 340. If not how do you drain the hyd "tank" under the seat?

Top cover is two piece with hydraulic reservoir in upper section. I don't remember where the drain port is but should be along the side of reservoir.

No the hyd tank is a seperate sump from the trans sump,it has its own check and fill plug along with its own drain,if I remember right the drain is on the left side??? of the square hyd tank,look for the lowest port or hose or plug on the tank and have a drain pan ready...
A 340 is in the family of the 460/560 and thats when they officialy went with the common sump design..

This ones decent old girl my dad and I picked up to restore some years ago with a bad valve. I started with eagerness and did the typical: head, water pump, rad, belts, straightened the tin and cleaned the tank and carb. I even collected all the stainless emblems. It has a front pump and power steering which was working good then got intermittent. I am going to check the orifice in the hyd next. Hey, whats the little plunger looking thing in the top of the block that has the orifice in it? Is that the check for the fast hitch? Dad went to assisted living now and I need to downsize the collection so I am cleaning up a few to sell.

The fill plug is under the seat, I just pull the top cover and then get the old oil out.(a hoist or cherry picker is needed) that cover is heavy.

redtom- the filter is the screen under the seat. Lift it "STRAIGHT UP" when removing. Pull one bolt, buy 3 extras about 10-12 inches long. Grind off the heads. Takes out all the bolts (3 lengths)and number as to which hole they came out of. Use 2 short ones to mount a hunk of scrap chain across the holes in the center to make a handle. Not the res. mounting holes, the other ones in there, (you have the seat removed right?) Now get the young strong guy with no back problems to hop up and lift the thing straight up while you get some blocking under it, opposite corners. Look it over ( and under)and it all becomes obvious. That screen is about $160
Clean and reassemble. The new gasket is about $20. Don't use any gasket in a tube stuff. You will use to much and it will get sucked into that screen. No teflon tape either. Install the 3 bolts with the heads ground off finger tight on the corners, then the new gasket, now the resivour. The headless bolts will keep it all lined up nice. Now put the real bolts back in, you did number them right?
email me if you need the bolt pattern
