David Brown Part 1 Oil, Air and Fuel check up 

Best David Brown instruction on RU-vid! I have had my 1974 DB 990 for twelve years and love it. I have learned so much from your videos that I could never find anywhere else, especially hydraulics. I have much respect for heavy British metal and engineering from that era. Ga zo door!

My 990 just stopped working during some job. It is probably an issue with the fuel filters that are clogged. Thanks a lot for the video, now I can try fixing it !

What a great video. My trusty David Brown 990 is in for an overdue and proper service treat very shortly. Many thanks.

Darn, I don't even own a tractor, but I watched the whole thing! You are such a perfectionist Steve, just like me. How many of you viewers said out loud, stop pumping Steve! Lol. Cheers from Michigan USA

I have a 1967 David Brown 990. Your videos have been an incredible help since it is extremely difficult to find someone to do the maintenance for you. Please keep it up! Blessings.

Never seen such dirty fuel filters before, this tractor also needs cleaning of the fuel tank! Great video as always.

You have a good trusty old friend in that David Brown 🚜👍

Epic, chief! I just bought an 880/A Selectamatic that has been criminally abused. But thanks to your videos and my dogged determination, she will survive.

Good engineering on that tractor. For comparison, my new MB car has the fuel filter combined with the electric fuel pump and the fuel level sensor all combined and installed INSIDE the fuel tank. When the pump died last spring my regular mechanic couldn't change it since he's not privy to MB's secret diagnostic codes and the car had to be towed a second time to a dealer. The warranty had expired the prior year so the bill was all on me. The fuel pump unit was priced at just over $1000 and by the book required 7 hours of shop time to replace (the fuel tank needs to be removed from the car), at his shop rate this added another 1300 dollars to the job on a six year old car with 80k miles on the clock. The car was out of service for almost two weeks. On my '99 MB the fuel filter and pump are both outside the tank, filter is like yours and replaced every 50k miles. The car has some 160k miles and has had only one repair, that for the 'electronic' fuel cutoff solenoid, cost about $200. The aren't better but they're way more expensive. My tractor is a newer Kubota that is engineered much like yours, all mechanical.

Lovely old tractor 🚜.. Thanx enjoyable video. 👍

That is a thorough maintenance service. If everyone did this periodically their cars and machinery would last forever. We like Shell Rotella for Diesel motors and older flat tappet motors. Great video as always. Thank you Steve!

no wonder this is such a well built machine..the tie in to AM and David Brown was new to me..thx..

This and your hydraulic service videos are of great use to me. Thank you so much 👍

Very nice video, as always.

I’ve just bought the same tractor, but an earlier model with the smaller metal rear mudguards, and know nothing about it, so I’m glad I can use your vids as a tutorial on how to service it. Looking forward to more on the DB990, thanks.

Wonderful job you are very through class job i have 995 its 50 years old but works well go forever BEST OF LUCK AND GOOD WISHES FROM WEST OF IRELAND

I was watching you Work on a David Brown Tractor ..while eating Mary Brown Chicken and James Brown was playng in the background on the Radio!!!...

A great video, I enjoyed watching it. I was taught by my father when a young teenage girl, how to service the 990. However, changing the hydraulic filter I do not like. I always feel as if it's never complete before replacing it's cover.. When on my own to prime the fuel, I made a cord with a hook and slung in over the cover and attached to the levee hole. Pull and release repeatedly listening to the tank flow until I could see the air was gone. Yes, it is an amazing tractor to work with and under rated. Thank you

Thank you for these great videos! As a pretty new DB 990 owner these are truly a treasure chest! I should be changing a leaking frond end crankshaft sealing before it gets too cold here in the Nordics for these kind of operations.

Great work on that old tractor😎👍

Ghoeie middagh Steve. David Brown tractor with a John Deere baseball cap lol 😆 Hope you and all your family are well. Back in England things are returning to some sort of normality and hopefully Belgium and the rest of Europe will follow soon. Really interesting and informative video as always. Take care cheers Stevie.

Great to have such wonderful “toys” to play with!

Well done on your great engine service video,I also have a 1966 990. I will also look forward to the next part Thankyou 👍

Fuel filter #2 was also full of gunk, so I think the injection pump fine strainer (if there is one) needs to be checked and cleaned/replaced. And the shape of the fuel tank would let a lot of fine atmospheric dust collect at the bottom and over time form the gunk - diesel has properties of attracting water and dust. So, I think the tank also needs to be inspected and cleaned. Thanks for posting.

I have a 1973 or so 885. I am learning a lot from you! Many thanks.

I have one the same David Brown 990 selectamatic 12 speed 1971. I like your videos, just subscribed.👍

Another great video Steve, keep them coming!

G'Day Mate, I own a David Brown 990. Afterwatch this very informative video, I'm thinking the fuel tank and the lift pump would need cleaning. Going by the condition of the filters. It would be very good to see a video on putting in a new lift pump kit. Thanks again. Regards Bruce

Beautiful love it I want David brown tractor

I have a 1985 Case 1294 the engine is made in the way the David Brown tractors engines are i will change the fluids on it next year, the people dad and i bought the tractor from did the service on it, changed the starter, lift pump and tires on it 😄

The early Land Rovers have those oil based air filters. You’d never think that oil would be used to filter air in a vehicle!

David Brown made tractors which are some of the slowest of vehicles but he also made Aston Martins which were amongst some of the fastest at the time. They made the iconic DB4 Aston but sold the company in 1972. DB came from the owners name. I think you definitely need one of these cars alongside the tractor !

high respect 👍🏼 very good explanation and video editing. Best regards 🇩🇪

Very useful and informative information. This is just like my Grandfather's 885N that l need to change the fuel filters in. This video will make it easy for me.

At 7:30 I have seen factory holes in a tractor radiator to allow the steering shaft to pass through.

Oh Yea! Old iron! Electronics are good for some stuff (RU-vid?) but then again just steel and gears do it for me. One of my favorite things to see is an older Diesel engine sitting on the ground with no wire except to the starter, no radiator, no electronics, and it fires right up and keeps chugging. The simplicity is just great. I'm just fighting now with the EGR system on my 90s truck and (ironically, cuz they suck) the vacuum diaphragms and all are fine but the ECM-controlled solenoid valve is likely the intermittent culprit... geez... And I need to pass a smog test...

Just cleaned the air filter on my 990 selectamatic,took the complete unit off the tractor . The "oil" in the bottom was black sludge with lumps of ?. There's a second filter above the the oil bath filter which I think is fixed into the housing.

Great work and video,and i 100% agree with you that David Brown tractors are the best one ever made in my opinion, we got 885 just like you said starts every time any time and will never let you down.

The tractors from these days were very much alike. Massey Ferguson and Ford tractors from the 1970s are also nearly indestructible. Those things keep running even with very bad maintenance. And a big plus is no electronics at all. Can be started with a screwdriver between the contact points.

Sir, you deserve more subs. Can't understand why on earth you don't have at least a 100k.... Jeez. Keep up the content.

Great video, You should name the part Specs so I can find them here in Colombia, south América

Hi I am from Sweden and have a similar DB 990 selectamatic from 1971. I have some experience of doing service and renovation. What I want to convey is your calm and methodical and informative way how to change oil + filter on this David Brown. And you have a new follower! And besides what you did here. Do I have a bigger job on mine when the left brake stopped working. Pedal / link system completely fixed😱😬😬

Awesome video..thank you

Very Very good quality 👌 of work

Very.thorough.

Thank you so much for this video. It's exactly what I needed to see. I'm doing all of that to my 1967 990. One question....there is no fuel shut-off valve? I couldn't locate one on my tractor.

Thank you for the great information you give us on our DAVID BROWN tractors. Can you what color red you use on your tractors? The contrast it gives to the white tractor. I want to use it on the air cleaner, muffler, grill, and filler caps. I look forward to all your shows. Thanks so much. Utah Jim

hi, a lot of vehicles had oil bath air cleaners in the good old days. including cars and lorries, usual made by AC- Delco or Burgess.

Hi Steve. Was the black stuff in the fuel filters like jelly? It could be what's commonly known as 'diesel bug'. This actually grows in the diesel. It's an organism, and can be treated with a biocide additive in the fuel. Modern diesel suffers more with it as a result of ethanol being added to diesel.

Excellent video, very informative!

The fixing of the sump plug is a plan made by the previous owner. We call that in Afrikaans 'n boer maak 'n plan!

Those oil bath air filters are supposed to be very good. They were expensive to produce, which is perhaps why the manufacturers began using paper elements.

Amazing vídeo thanks for the help keep on the good work

Nice service job. Such an easy access to work. How's Old Rusty doing? Thanks for you videos and looking forward for the next one.

Very nice, ordered and calm. Thanks so much for the time to video & edit this down. Some 990s (most?) have no stop-tap on the diesel tank, so diesel flowing whilst changing the diesel filters expected? Also, the oil-bath air filter has two mesh filters closely connected (on mine) - mine wouldn't separate and they're very tight - so after cleaning it, it went back in. I was curious to see if you also cleaned/changed the lifting handpump gauze filter on the other side, or is that an unusual activity rather than annual maintenance. Thanks again, great sequence of videos. Jeff, UK.

Great video - FYI BOLD should be BOLT :-)

I remember my father's '50 Chevrolet, it had an oil bath filter just like on your tractor, I believe this was common before the paper filters came on the market. Some farm ops might clog up a filter rather quickly. I was surprised that each of the fuel filters had the same element, practice I know is usually a 10 micron filter first followed by a 3 micron secondary, yours were very dirty, either you didn't change as often as you said or you are getting really crappy fuel. Was there no gasket on the engine oil pan, that would be strange? My Kubota has only a single stage filter but with a clear case so you can see any trouble brewing. The air filter on the Kubota has 'turbine' blades to spin the incoming air so that dirt particles fall into a collecting pan rather that into the filter. I fully agree that a low stress mechanical diesel, probably an OHV design, is a great low speed tractor engine, I see a lot of old tractors still earning their keep 40 and 50 years later and a lot of folks rebuilding them to run like new again. Keep up the good work and please keep the videos coming. What is your day job, not asking you to be too specific but what type of work do you do?

Absolutely brilliant video,very helpful.is there a sump gasket.

I have same traktor IMT 558! It’s licensed from Masey Ferguson,engine it’s originally called Perkins engine!

Hi and may I say you are excellent and making this very clear, just one question, I’m new on tractors and very little knowledge in any Machanic’s but just purchased and being delivered 26th Jan 2022 so very excited it’s a DB990 and I believe 1960, my question is are these 990s all the same, the from my 1969 to your 1970 i.e. body and filter sizes etc… I’m hoping to totally follow your video instructions 🤞 keep the brilliant work up 👍

14:20 Was that a Wax On Wax Off moment?? You told us to blow reverse direction to air flow...then flipped it like Mr. Miyagi did !!! 😉

Absolutely fantastic machines, ran on free air compared to a ford.

I have a DB , Allis WD45 x2, IH farmall model A and a Cub!!

Fijn zo'n opfrisbeurtje :D

That's a lot of dirt in the fuel filters, need to do mine now...

thanks

they need to make david brown tractors again like the 990

What do you reccomend oil grade for the power steering on these old gals?

First of all let me say, thank you. I just found you today while looking for info on my David Brown. Already I am a huge fan. It is very easy to get pulled into the lesson (for a lack of a better term) and excited about getting back to Betsy (sorry, I name my tractors) and trying out what I've just learned from you. I have a renewed confidence in my ability. So again thank you. I have a question . I totally understand if you cant answer it as I realize you probably get thousands of questions but just in case.... there is an "extra" fuel type filter between the seat and fender on my Betsy. What does it filter? It is a 551309 filter. I had originally believed it to be for the hydraulic system however, after watching your videos today I think not.

Great video. When do you plan to go on with OldRusty?

Hi we have a David Brown 990 tractor but we don't know where to put in the hydraulic oil. Please help urgently. We are stuck.

Steve, I have a 1210 Selectomatic and the 3 point sector selector (ECT TRACTION CONTROLL etc) won't come go into the normal raise and lower position. Would you please explain how to check if it is adjusted correctly ? If you have not done that yet.

Hi there I have a old 990 David Brown which has a fuel injection problem. The diesel comes out around the injector when it is revving. Can you please help me in solving this problem I replaced the copper washers but it still is coming out around the injectors when high revving. Can you please help solve this problem.

Hi Steve I enjoy your videos very much, you explane the details so excelent. I have a question: where do you get the gasket for the valvecover from? I need one for a 990. That one we have, doesn't fit. Its about 5mm to long. I dont know how that can be happen? thanks a lot for your answer. Roger

My David Brown 885 cranked but won’t start, any suggestion?

Can you tell me where can i find the torque specs for this tractor mine is a 990 also but the engine is the ad4/47 its the 3.0cc i AM changing the internals on the engine but cant find the torque specs thanks

Queremos noticias de old rusty...

Where’d you get those coveralls!! They look great, would stop me from ruining my nice clothes lol

what oil should be in the air filter?

Hi, how did you get the diesel pumping through when bleeding, what manual lever were you using? The throttle? Cheers

Hi Steve, would you please tell me why you never purchased a good used high quality Turner or Bomford bandit hedge trimmer flail mower instead of that junk .

Hi Steve, I think you may have put the wrong date on your oil filter, shouldn't it be 17/04 (unless of course you made this video in March). Cheers, Stephen.

Do you run NON detergent or detergent oil?

Those filters are the WORST i've ever seen. how it even managed to run is amazing... I'm sad they went away with the Oil bath filters those were Great!

What’s the bleeding time ? 5 to 9

What crops do you grow?

👍

What's with the one down vote..

Hah! 990th like on this video!

Thanks for the video - I have my eye on a 880 Selectamatic so it was particularly interesting. Google “Form A Funnel” a simple but useful tool, especially for these jobs. M@

Hi my friend STEVE please have a look at this video, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OEqY7PfvN5U.html there is an other one more for tools equipment accessories et...... I am sure you go there and will come out with a low bed truck FULL just an ENORMOUS place full full full of very interesting staff !!! I know it is far from you but one never knows .....Warm regards my friend !!! Let me know your comment !!!

where can i get parta fore My 990
