Brand new here, hope this question has not been answered before( I couldn't find it in FAQ) I just aquired a JD 210c with the product id of *T021CA728468* and engine serial T04239D1414890 and another number on engine plate 423 (0) (i think looks like a degree symbol) DT002

Does anyone know the year, and more importantly, what is the correct procedure for checking hydralic fluid? This was a buddies grandfathers machine who recently passed away. He does nothing with equipment, and asked that I take it off his hands and add it to my farm. I have never owned a JD, could not afford any. I have a ford 5000 rc tractor, IH dozer ect. So I have not books or info on this machine and the JD dealer is closed. I drove machine off my trailer and dug a hole about 8 ft deep. All fluids looked good and level with it shut down and cold, (Hydro. fluid 1/2 up dip stick) running hydro fluid was between h and c marks. As I was driving it to my barn, hydro's started whinning like it was low on fluid. On the right side of machine, under wheel well cover it was blowing hydro fluid out from the rear most hard line. Looks like this is a feed line that goes to the (splitter) where 6 lines, 3 rubber hose, 3 hard line hoses, all split off and go different places. I shut down the machine immediatly and lowered all the front and rear buckets and lowered outriggers not putting pressure on any of them as the machine was turned off. I removed the wheel well front plate to access the hose connectors. The rear most (toward rear of machine) hard lines nut was only hand tight. I unscrewed it and checked the o ring. it was crushed on one side almost in to. I replaced it with a new o ring and re tightened nut. I could see hydro fluid it hose and checking fluid while standing on the ground on the right side under the foot plate, fluid is still 1/4 to 1/2 up dip stick. I have not started machine, wanted to insure it will not harm it to do so. Question is again, what is the correct procedure for checking hydro fluid? Where do I add it? Straight into dipstick hole? will hydro fluid I use for my dozer/tractors and other equipment work? I am a swat team member, and have to return to duty Sunday and will be on 12 hr shifts thru Saturday of the following week. Thats why I tried to include all the info I thought may be needed. Thank you all in advance for reading and hopefully answering.

That machine was delivered May 19, 1986 in Montgomery, Al. Check and fill the hydraulic at the dipstick. The hydraulic oil you have on hand will do, in a pinch. I'm sure Deere would recommend the Hy-Gard, but any good hyd oil will work. You may have enough oil in it to limp to the barn. Try starting it. If the pump whines for more than a few seconds, shut her down and add oil. Good luck. Holler back if you have problems. I will monitor for the rest of the evening.

Thank you for answering so fast. It started fine, not sound other that motor, no whinning. it will not lift any implements. Do I need to allow it to warm up and then check fluid? Does it have a bypass for air, or do I need to bleed it off? And hydro fluid I have is Hy-guard.

Go ahead and fill the hyd to the proper level and try it again. There should be no need to "prime" the system. I believe the line o-ring that you blew was on the pressure line to the loader valve. The pump should put pressure to the trans and loader functions before opening a pressure control valve that supplies oil to the backhoe. Keep me posted.

Do I need to have it running to allow the hyd fluid to move about the system? Checking it right now, with all arms,riggers down and not under pressure, the fluid is almost to the top of dip stick. C and H levels lines are at bottom of stick. So do I let it warm up and then check level? Thanks again for answering

You're welcome. The level will, almost certainly, drop once you get the air out of the system. I would not expect a drop of more than a gallon or two. If there are no angry pump noises, try your steering and loader functions. They may be sluggish at first, but should smooth out after a few cycles.

I believe I have been checking the wrong dipstick. I think I have been checking the trans fluid. The correct location of hyd dipstick is in the front right side of machine under hood above the cooling fill isn't it?

I would expect the trans/ hyd to be a shared system. Give me a few minutes to confirm.

Edit: I'm just working with the parts program here at home. No access to construction manuals. It does appear to have a forward hyd reservoir. Fill her up.

Part #13 is the dipstick for the hydraulic reservoir. I could not find the owners manual online for you.

It's from www.jdparts.com the same basic system the dealer uses at the parts counter and it's free to register there. There is a quick tutorial linked in my signature if you need help with it.

Kennyd, can not locate anything that looks like the pic. On the floor there are no dipstick checks. Under floor on right of machine there is a dipstick, but it has to be unscrewed and looks like a trans dipstick on the rest of my equipment. Can not see any hyd line going to this resevoir either. Under front hood on right of machine, there is a cap and short dipstick (6 inchs maybe). Fluid is very low on it.

I just edited my post's above and added the descriptions. That is about as much as I can help unfortunately.

I did find this picture though:

Thank you both for the info and link. I see where it shows the area I was asking about as the hyd resevoir but have yet to locate a dipstick location in the manual, but I will keep looking. Thank you both again, and a owners manual will be ordered Monday.
