Draining the Hydraulics

CHUCKWAGON · Jun 4, 2005

Need Help & Advice.. /forums/images/graemlins/confused.gif
I drained the Hydraulic oil out of the 3 point system no problem. Replaced all of that Hydraulic oil with NAPA's green label Hydraulic oil. But when I attempted to drain the power steering and front end loader Hydraulics, I only got very little out. I opened the lines in different places still nothing. Maybe 2 qts or so. Can some one please tell me what I'm doing wrong? /forums/images/graemlins/frown.gif Thanks..
BTW I have a 2430 4X4 Farm Pro, w/ a Koyker - 160 Front End Loader

Most of (the majority anyway) the hydraulic oil is in the resevoir. I doubt you will get any more out than you did. The only thing different I did was jack up front end and turn steering wheel with the hoses off the front cylinder. I didn't get much, maybe what you got. There will always be some oil in the FEL cylinders that you will not get out, unless you took them apart which is entirely unnecessary.
As long as you got most I'd say you are fine.
Some may suggest to flush with kerosene. I didn't but thats my choice. You have your choice.
Did you pull filter(screen) thats under seat and clean & inspect? That I did do and all was fine but some guys found debris.

Like Harry, I only drained the tank and called it good after cleaning the screen under the seat. My hydraulics started working smoother and quicker in cold weather- immediately. That Chinese fluid was nasty and has a flashpoint lower that gasoline. (I used it to ignite brush piles) The engine oil was the nastiest crap that I have ever seen used as a lubricant. My dealer told me that he didn't reccommend changing any of the fluids but I strongly disagree!!

Wheww I'm good to go then, /forums/images/graemlins/laugh.gif Thanks guys at least I know everything I did was normal ( but truthfully I did think more should of drained out ) Yes I did do the screen also, mine is located on the left side of my machine, it was clean from gunk & junk. I did notice the controls responding better, smoother, & faster. Now to put it to work, time to hay the fields, just watching the weather for a few good days.
One less thing to worry about. /forums/images/graemlins/grin.gif Thanks again

I drained my system much the same way you did yours, drained the tank with the FEL and 3PT in the fully raised position, and then lowered the FEL and 3pt fully down with the reservoir drain still open. I was very pleasantly surprised that hydraulic fluid that was in the tractor was good looking oil about 40W but clean and water free. Took the screen out and cleaned (very little dirt / crud a few specks at most). And sucked out about a quart with a turkey baster that remained in the reservoir after it had finished draining. Refilled the system with AW32 and the system works great.

Next time you drain the Hydraulic fluid remove the suction strainer again then remove the end cap of the strainer and take a look at the "Glue" that holds it together.
Mine was dissolving and falling apart - Brand new tractor with 10 hours on it. I removed mine and are installing an external spin on suction filter from northern tool.

My filter did not have any "glue" holding it together. It was made up of three main parts a cap with a thick rubber washer on it, a cylinder with holes in it wrapped with a very fine brass screen and the bottom assembly with a tube passing through a flat plate with a rubber washer on it. Basically the cylinder with holes in it wrapped with a very fine brass screen is clamped between two plates with rubber washers on them; a bolt clamps the assembly together. Honestly it is not a bad design very service able and sturdy. But my Jinma is new made 12-2004, I have noted a lot of design differences between mine and earlier Jinma’s such as a different oil filter, the filter mentioned above, permanently sealed bearings on the water pump, Ect. Also for reasons I cannot explain I do not seem to have very many metric bolts on my Jinma. I am a very experienced Volkswagen mechanic and of course most of my tools are metric , However most the bolts on the Jima that I have worked with were in inches (American ) I really cannot explain this as most manufactures are going the opposite way. Any one have any thoughts.
