Absolutely amazing videos! My father passed away before we had a chance to talk about his David Brown 990, and thanks to these vids, it will run on now! You have no idea how much I appreciate your work! Thanks a lot!
Grew Up in Ireland. My Father had nothing only DBs. 990 & 1200. I’m now Living in Pennsylvania. I have two DBs. A 770A. And a 1212. Memories of the Nest I Flew From. I’m Hoping to Restore Them to Full Glory. Someday. But I need to Learn From this Gentleman
Thanks for the nice comments, I guess its up to me to make it better and get more interest. But then again its a channel with content that not so many might like
I’m sure you’re sick of hearing this but man I can’t thank you enough for making these videos. I feel I have an actual shot at restoring my grandfathers 885 because of you.
Hi Steve flemish. This was one of your most simple straight forward video. When I first saw the title of your video I paused and have a bath so that I will have time to listen attentively to you. The title said gearbox and hydraulics. I am disappointed that you did not open the gearbox. I thought there will be a necessity for you to dismantle and explain the gearbox. I understand well when things and said by you Mbs moshitoa (south Africa
Great videos. Am doing my 885, according to the parts catalogue there should be a magnet inside the spring in the screen attached with a BA2 nyloc nut, yours seems to be missing.
I have a lot of David Browns. I always remove a gear shift lever to fill directly from a 20 litre pail. I empty the transmission with a hose plugged into an external coupler. This just leaves a few litres to drain underneath.
My wife and I just purchased a David Brown 990 tractor as our first and only tractor on our farm and I must just say thank you so much for your videos. I have never worked on any sort of vehicle before outside of changing tires and your videos are so helpful. I'm changing all of the filters and oils and I'd be pretty lost without you. So thanks and keep up the great work.
My 880 David brown has the mesh filter ,where can I buy a new one cause mine has detereated.all i see online is the one your showing but my cover will not go over it.
I am not very familiar with these tractors but I was under the impression that the transmission oil serviced all the hydraulics and the axles. You only drained the oil in the transmission. Does that leave residual dirty oil in the axles and loader hydraulic lines which will contaminate your clean oil? Are you sure you don’t have to drain pto , axles and all locations not just the filter sump?
Yes you are right, it servers all those...there will be some residual oil indeed that is why I make sure the pistons are down... I should have stated that . I will do a check on what you stated, and you might be right.
I HAVE AN 885 WITH HYDRAULIC ISSUES. MY LOADER LIFT IS SLOW AND NEEDS THROTTLE TO LIFT AND WHEN IT IS HOT IT WON'T LIFT. COULD IT BE THE FILTER, I HAVE NEVER CHANGED IT IN 3 YEARS. I HAVE SWITCHED THE LINES ON THE CONTROL VALVE BUT NO CHANGE.
Hi Steve, I've a 1394, which is similar to your tractor. A lot of people use super universal oil in the engine and hydraulics. Seems strange not to use hydraulic oil when you could be mixing implements with modern tractors. I think that the rear lift needs to be up or down to empty the cylinder, so you might have some litres there... Thanks, need to do mine now.
Fantastic videos!!! Well done, methodical and great explanations. Not sure you take requests, but I have a David Brown 885 and noticed just today the radiator was low on coolant and seemed to have a lot of junk/scale on the fins. Any chance you will be performing a coolant flush on your 990?? Keep up the great work and I look forward to your next video.
Great suggestion! I hope that yours will work out. I typical replace the core of radiator as flushing is not helping a lot when the radiator is already clogged... count for 200- 250 euro for a new core
you could use a piece of hydraulic tube to attatch to your rear external hydraulic line to empty most of the hydraulic oil before you unscrew the plug in the bottom, that way it's less of a mess. (je kan eens tuk olieleiding in de achterste pries de force steken en het merendeel van de oil zo aflaten voordat je de stop losdraaid, dat werkt properder)
Mr. Steve, I have a question. My father has a David Brown 990 but the PTO keeps slipping out of gear when engaged. The PTO works and spins the brushcutter however it quickly slips out of gear after a while and disengages. Do you have any suggestions on how we can fix it? In addition can you go over the operation and schematic of the PTO on the David Brown 990 in a future video?
This can happen with most any tractor. When I am bushogging with my DB 990, I pull the PTO lever forward to engage it, then I hook one end of a strong bungee cord to the lever, and hook the other end on whatever other part of the tractor that will keep a firm tension on the lever. Works perfectly. Just remember to remove the bungee cord and disengage the lever before shutting off the tractor so the momentum of the bushog blades don't continue to turn the PTO gears when the motor is no longer supplying power to the PTO.
Hoe de retourleiding nu aangesloten is is juist NIET goed bij deze selectamatic modellen. De retour wil je altijd aansluiten op de aangewezen plek bij deze trekkers en dat is op het 'kamelenbultje' rechts naast de stoel(staat er ook op ingegoten) dit geldt ook voor een extra aansluiting zoals een ventielen blok of gewoon een enkelwerkende snelkoppeling. De versnellingsbak wordt als je hem dus goed aansluit gesmeerd met druk vanuit het hydraulische systeem en niet door dit drukloos te dumpen door de vuldop.
Bedankt, en ja met deze tractor is er geknoeid in het verleden... deze kwam zo toen ik deze kocht. Er is trouwens nog wel het een en ander dat niet correct is ... zal het bij de volgende video wanneer ik de haagschaar monteer even aanhalen.
I don't speak Dutch but seemingly this is exactly what I was going to comment. Implement's free return shouldn't be through fill plug, but as above said, to the "camel's hump" front plug. There's also another "official" return, on axle casing left of the seat is a plug for this purpose. Just wondering could this above comment be translated into English for wider audience. Otherwise this video is excellent like your others too.
I am so happy i found this sight!!!!!!! I am the owner of a David Brown 990 diesel I have all the appropriate manuals but sometimes run into problems. You make everything so easy and understanding. You helped me out with the explanation of the hydraulic system like no other. You went through the operation A to Z and helped me out . Even standing on the arms to drop them . I will be watching your videos religiously learning things i never even thought of Thanks a million
Just doing this on my Case 1290. I discovered that someone has left out the strainer and valve assembly so I had to find a new one. I have put it all back together but I cannot find the fill point. It is not the same as this one. Any suggestions?
I heard you explaining 15w40. Is so strange that the hotter the engine becomes the thicker the oil becomes. Wouldn't it be difficult for it to reach parts in time and lubricate them. Or did you do tangue mistake Mbs moshitoa south africa
When referencing motor oil weight, you are actually referring to the viscosity grade or the tendency of a liquid to flow slowly or quickly. The Society of Automotive Engineers (SAE) developed a grading system to designate the viscosity level of single grade and multigrade motor oils. In single grade oils, the lower the number, the better it flows at cold temperatures. Likewise, the higher the number, the thicker the oil. In regard to multigrade oils, the first number in the code, such as 10W in SAE 10W-30, means that the oil can still be pumped by the engine at a temperature as low as a single grade 10W oil.
Bonjour je suis français et j'ai un tracteur david brown selecmatic 990 je doit changer le filtre d'huile hydraulique. Connais tu le couple de serrage du couvercle ? Merci
Hola soy de Chile me gustaria que mandara los sub titulo en español Me gustaria ¿ si el aceite hidraulico del tractor DAVID BRAWN 995 Es 15w-40 al igual que el motor o es diferente .y aceite hidraulico es el mismo de la caja y diferencial porfavor digame en ESPAÑOL .
Hi Steve, thank you for your videos! I recently bought a 990 selectamatic and the lift doesn't work. I'm going to try to change all the hydraulic fluid and filters. Greetings from Uruguay.
i have a david brown 880, i live in america. the local Case Dealership said i can use a fluid called Hydratrans oil. i am worried it may be only for new tractors. what do you recommend i should use for my hydraulic and gearbox oil?
Well I use general all round TracOil as they call it. It goes in the hydraulic system and engine... I think that Hydratrans will be OK the hydraulci part
One thing I've never liked about our David brown 1412 is the draw bar Is it just me that has trouble with lynch pins breaking? That hold it in place this is tractor dealer bought ones not cheap off the Internet
Great videos im only new to your videos I have a question maybe it's in one of your other videos we have two 995 n both hydraulic oil is contaminated by water a milky colour ive been told to drain oil n flush with diesel have you ever done this n any info would be great thanks n keep up the great work
Good questions, if you look careful you will see gearbox safe on the dipstick. meaning that there is enough oil for the gearbox. However that does not mean that there is enough for the hydraulics to drive pistons and ancillary elements. In other words , that little bit of oil ( 17-18 ltr) is enough for the gearbix
Thanks for the comment, we just enjoy it the way it is, Living Apart Together (LAT) is great. its always party time when we meet and lots of me-time when we don't meet...
After changing the transmission oil the tractor seems to struggle on even the slightest grade and has to go into the lowest gear. This never happened with the watery sludge that was in it. I hate to impose but you are pretty much a mechanical guru...do you have any idea what is now going on, is it the clutch or what do you think...thanks in advance
Thanks for the comments, that is very strange.. does the engine rev up and the tractor picks up speed slowly ? if so that could be a clutch problem. But that would not explain why it would be affected by the oil change. What does it do in neutral ? does it rev ok ? does the lift works properly on idle ? Are you sure you don't have the manual brake on ?
Everything seems to work well, loader, 3 point hitch, engine purrs like a woodchuck and it travels well on level ground. No I’m gonna sound like a real clown... but I have no knowledge of a manual brake 😊 where would I find that? I have to confess this is a tractor I got for my son’s hobby farm and the whole thing is a puzzle to me, so many knobs and dials and levers and none of the tags are readable... I’m gonna need to buy a manual on line... thanks you’re an amazing young fellow!
@@oldcrowe no problem, normally when sitting in the seat you will find a handle on righthand floor next to the bottom of the fender ( RH) .. that is the brake and make sure its in the down position.
@@D3Sshooter I don't mean to be a pest, but what attachment ? I have a similar tractor, is that a factory installation ? Also are most of the implements 3 point attached, Are there trailer type equipment that hook to a draw bar, and depth is controlled by a hydraulic cylinder raising and lowering the tires? I really enjoy watching you work on your projects. Thanks
Hello Steve and thank you for the informations you provide. I have the DB 990 implematic the red one 1964 model. Suddenly while i was working, the lift arms didn't work. I pulled the lever up without any load, and the arms worked and went up but when you put weight they don't. I'm assuming that might be the hydraulic pump or it needs changing the hydraulic oil filter and the oil itself because it might have some dirt in it and blocks the good flowing of the oil, so the hydraulics can work correctly. Notice that when i am revving the arms move better but again can't lift weight. What do you think it is the problem?
Well they should lift with weight , have a look on the video that explains the entire hydraulics system... I am sure that you will be able to diagnose your issue after watching it as it could be so many things. Most likely mis adjusted or possible a pump issue ... measure the pressure of the pump if in doubt.
Very nice videos. Fine with oil change at engine and hyd, filter change too, but renember the final drives at the DB's-they are under a hard load and often running in old worn oil with condence water in it.
