Just got a nice running 1500D and after draining and replacing the jd303 fluid, I noticed there is a drain plug under the rear end case as well as under the transmission case. Do they both drain the same reservoir or are they separate systems? If the same, should I be draining both each time I change the fluid.

Is there a filter or screen for the hydraulic system, and if so, where is it?

The fluid I added meets the JD303 specificaton but was much thinner than the red stuff I drained out. Now the 3-point is sluggish and I get hydraulic squeal even when raising it empty. Filter or screen? Purge of some sort?

Also, do I need to remove the fuel tank to check the steering box oil or is there a wizzard trick to get around that?

Thanks for the great service on the parts and manual I ordered!

Yes.

Yes.

Behind the suction line. remove the plate that attachesthe line to the trans & remove the screen

Clean the screen & it should fix your problem.

They are very tough to service. it is not uncommon to have to remove the box completely & clean out the sludge.

We appreciate your business!!

Drained everything again, cleaned the screen and everything is happy in the hydraulics now.

It was very clogged with something that resembled black jelly that was kind of hard to remove the fine stuff from the mesh. I ended up taking the screen to my auto mechanic and he put it through his part washer. Did the trick.

Thank you once again.
