Need info on DB885 or Case 380CK !!+

Hello Everyone,

Can anyone send me a picture or describe the levers and knobs that pertain to
the operation of the 3 pt lift. Mine was operational 3 years ago, but has sat
in a garage without use because of missing parts for my mower. I want to use
the 3 pt again, but have misplaced my manuals and most of the decals are so worn
it is not possible to read them. I have 4 other tractors, and have used this
the least, so I have forgotten how to work the pt. I just dropped the large
round filter on the bottom and cleaned it out and replaced the milky fluid. The
arms will not go down and I need instruction on how to operate it. I may have
to replace the manuals, so if someone knows the best place to get them , please
let me know. Any advice will be greatly appreciated.
Thanks, pj

There is a mechanical lock on the LH side (from rear). It is a cresent moon shaped lever. Rotate it so it moves outwards to the rear. If that doesn't work, check the selector lever, (a small thumb lever down below the seat on the RT side as you set on the seat) Pull the white quadrant lever all the way back against the spring and turn it to the Heigth position, (center I think). If that thumb lever is in TCU the system will raise the hitch armes when you push the white depth knob all the way down. There should be some remnances of decales on the quadrant, Blue ones at the bottom are Matched to the Blue area on the Thumb lever and will raise the arms with no load. If you are in heigth controle and the arms won't drop, you will have to get into the chest valve an free it up as described on this forum and tractor talk. Perhaps Rich will chime in with more detailed info.

I do have a part manual or service manaul for the 380CK or Operator manual for 885. e mail is [email protected]

Loren,

Thanks for the response. This tractor was repainted and all the decals are either so worn or painted over that they do not offer any guidance. I have read the FAQS and will attempt to bleed the system. I know that the pump is working because I have pressure running to my 5 ft side mower. I used this 3 point around 8 years ago, and because I normally only use this tractor as a mower, the 3 pt has never been an issue. When I dropped the bottom filter there was a fair amount of sludge cause by water in the trans/ fluid. I changed the fluid and replaced the filter and cleaned the screen. I will attempt to bleed the system as per the FAQ"a, but I believe they are for a 900 series. THe diagram looks alike my system, so it is better than nothing. I need to find a mamual , because without pictures and explicit instructions I am just shooting into the wind.

Thanks for your input and advice,

God Bless you,

pj

990 and 885 hydraulic systems are identical.

Loren,

I was trying to follow the bleeding FAQ # 5 and got fluid to come out of the hexnut that was on the plate on the clutch side. It also has the large nipple that I slackened but no fluid came out. That was with the engine running I had some one stand on the 3 pt arm and all of a sudden fluid came out like a gusher. I put it back in, but now when ever I use the hydraulics say to raise the mower fluid rushes out the nipple. I hope nothing came out with the fluid that was part of the tractor. I am planning to just put a plug in place of the nipple. Does any one have a diagram of that plate, that might show what is behind that nipple. When I first removed the nipple, it was clogged or plugged. It is now wide open. The good news is that in the whole process the arm dropped and I was able to raise the arms. RIght now the main problem is to stop the flow of fluid from the nipple. It is fine untill I use my levers to raise my mower which would be like a FEL setup,except the line run to two cylinders on my side mower. I was jusr using this mower last night and everything was fine, except for the 3 pt issue.

Thanks for all your help

That shouldn't be a hex nut, that should be a bleeder similar to what a hydraulic brake system would have, only bigger. I have one that a previous owner thought to be a grease fitting. He pumped the entire lift cylinder full of grease. That was a mess to clean up.


Nothing back there but teh lift cylinder

I bleed the system buy first loosening the hex nut until fluid flowed steadily. I tightened the bolt and moved on the the nipple. I loosened it but no fluid even when I took it out completely. I am not sure what transpired because I had friend standing on the arm and I think that he might have moved the quadrant lever. The arm dropped and a strong of fluid shot out of the nipple hole. I shut down the tractor and replaced the nipple. Now, when ever I use the hydraulics to raise the side mower, which was operational yesterday, a stream of fluid shoots out of the nipple. I am wondering if there was any part that might have been expelled with the first strong blast of fluid when the nipple was out. ANYONE have any ideas?

I was thinking of replacing the nipple with a straight plug.

Thanks for all the input,

I want to thank every one for the help on figuring out the 3pt trouble I was having.. Too sum thinks up, I now haave got the arm to drop and I know how the quadrant and the 3 pos valve works. If you read my last reply to Loren you would have seen that I removed the bleeder screw on the front side of the left axel. Sitting on the tractor, it would be rehind your left calf muscle. I have the screw, but when the fluid gushed out I believe that there was a 5/16 ball that came with it.

Does anyone know if that ball is exactly 5/16 ths?
Also, is there a spring behind it. Could I just get another steel ball and reinstall the bleeder screw. Could I also just find a screw plug for the hole or figure out a way to close up the original bleed screw? Any suggestions anyone?

I know I need a manual, just need to find out which book to buy.
Thanks,
pj

I found another 5/16s ball and pulled out the plug I had in place of the bleed screw. I got it to work. I can bleed the system properely.

The problem I am facing now is I can not get the 3 pt arms to lower with the quadrant lever. THey will fall over nite but when I start the tractor. The arms will not raise up unless I activate one of the mowers lift controls. I used this 3 pt 5 years ago and there was no conflict between my sidelift mower and the 3 pt arm operation. I did not do any thing to change hydraulic hook up since that time.

I think that I might have to take one of the valve assemblies apart and check it out for contamination. This tractor had a very milky Trans fluid and the filter on the bottom of the tractor had a lot of crud in it. I have the parts cd and operators manual but no service manual yet.

Thanks for all the advice
