@@JFFarviewFarm good to hear. We got 990 with lift problems slow lifting sometimes lifts ok. . Over 2000 psi on pump. Spool valve seems to be seating down . Cleaned bypass and hold valve. There is the small ball bearing missing in hold valve. Plenty oil flowing in back inspection plate. Flow stops when lift arms are rising. Any ideas ?? Thanks dave.

Hello sir. I'm having a problem with my Case 380 CK the 3 point isn't working properly. It raises when started but won't go down. But if you shut the engine off you can force the 3 point down by hand. I surely would appreciate your advice. Thank you

Too much oil flow building the pressure up and not allowing it to go down . When you cut the engine and it’s not pumping it allows the pressure to drop down and allow it to lower .

Hi, good vid very educational, I'm trying to remove the spool on mine(990, same chest) do you have to remove the small screw from the side of the chest to allow the spool to be removed, if your looking from the front it's on the left side (two of them) many thanks

The spool valve is the piece on top of the valve bolt with the two nuts . If this is what you are after you just remove the nuts , I’ll attach a interesting read with a lot of info on for you , give this a read the diagrams are very useful to understand how it all works . vieux.tracteurs.free.fr/pdf/David_Brown_selectamatichydraulics.pdf

How precise does the adjustment need to be on the spool valve? I have a 996 with the hydraulic arms not going down im pretty sure the spool valve is the problem although I don't have a manual to tell me the settings and im scared if i take it out the I could mess with the adjustment.
@JFFarviewFarm
@JFFarviewFarm 2 жыл бұрын
Yes a manual is needed to tell you the clearance of the valves and a dial indicator to measure the clearances as they need to be with a very small tolerance

I really can't tell what this guy is trying to do. I'd suggest going through the DB material before you start tearing into things. My 990 needs the outboard valve cleaned a couple times a year. All it takes is a tiny bit of crap in the passage. A lot of the info can be found here- sites.google.com/site/deerebrown/

Greetings from the French speaking part of Belgium. Congratulations for the beautiful restoration. I own a 3/45 since June 1970,it still running but I got a lot of problems with the original engine, I had to replace it by a renew engine of 3/42 :the original was mouthing but a mess, anyway the hydraulic and the frame were quite good for working with a fork. The Carrosserie is still good looking, this machine is my companion since 51 years. Bonne chance avec le 3/45 et encore toutes mes félicitations pour la magnifique restauratio !!!
