    Just a note first off to thank Ollek, Mr. Karl Olof Kullburg, of the David Brown Tractor Club Forums who originally wrote the instructions for these Group 3 adjustments. All I did was re-write them a bit more read-ably. Ollek was a staple for many many years on the old forum with the best of advice. Rest in peace Ollek!
    I'm so sorry Barry, I laughed soooooo hard when I got to the part where your cylinder bleed nipple was open! It seems you can't have a Group 3 adjustment without some sort of oil spillage somewhere or the other!
    Outstanding! I was so worried about these adjustments and seeing how they'd go for you! But they went swimmingly!
    Andy's right. Later last year, I reopened the back components to inspect them after the first few uses, I greased them up. I hadn't noticed condensation or corrosion yet, but thought it wise to grease those components. When I opened up for the first time many years ago, there was grease everywhere up in there. I think some comes out from the grease nipple on top of the righthand ramshaft near the selector.
    Happy birthday Debs!
    Oh, and p.s., There is ONE advantage to having the right fender on while doing all this. It makes for a really convenient mounting for a camera that's somewhat out of the way in the back! 🙂 Only way I could have filmed what I did back there. Annnnnnd that's the only advantage I think to having the fender on...

      Hi Shane, Debs says thank you, I was even thinking about taking the wheel off toget somemore room, I did get a comment once which said "why do you think the tyres are the last thing to be fitted"re the adjustments, I wasn't looking forward to it as I thought there would have been more leaks, things not working properly, and with so much having to line up and work at the sametime like the internal oil system
      Very plesently surprised that it came together in about three hours in total and only a "little" oil leak on the floor, whats a bit of oil when your messing the old tractors.
      many thanks

    Another brilliant video Barry. The Tractor starts on the first turn and runs great, all the hydraulics and lubrication systems working fine and the new Valve Chest is superb. Happy days you are doing a fantastic job and not to forget to wish a Happy Birthday to Debs.

      Cheers Terry, I'll tell Debs after emmerdale, more then my lifes worth to go in there right now! I think we're nearly at the end of the mechanical's for now, just lots of little things to finish off and then onto the electricals.
      many thanks

    I enjoyed that Barry, bought back memories. We would put the block the draft cable goes into with the split down so water wouldn't settle in the thread and the draft can be fiddled with to get very sensitive draft for light duties. Happy Birthday Deb! At 64 I'll catch up with you in October, Judy turned 60 while we were away on holidays.

      G Day Lance, did you enjoy your hols? looking forward to seeing some video's, I know what you mean about the block and it makes a lot of sense, so I'll turn it over next time I'm fiddling with it. Been up there today running the engine for half an hour to get it warmed up found a couple of little leaks which isn't a major headache so we'll get those fixed over the next fee weeks, good news is it only leaks when it running, so if I don't run it, job fixed me thinks.
      Debs says thank you very much, very much appreciated, please pass on our best wishes to Jude on her 60th
      many thanks
      Barry

    Well done Barry, great to see such good explanations on what you are doing, that engine sounds sweet! Thank goodness for some decent weather, got one side braking system stripped out, what a mess, everything clagged up with oil. Happy birthday to Debs!

      fingers crossed I'll get some more shed work done.
      many thanks

    Barry This was a very educational video. I am currently doing the same thing. I had the problem that the lifting bars lowered very slowly.
    First I turn on the button on the front.That wasn't it.Everything was expanded and I saw that the ridge at the bottom of the valve Chest. The spool valve Not or hardly pressed upwards. There are shims where the cam and the arm are attached. I took a chance and removed two of them. Now I see the spool valve Move up and down.
    It all comes down to very precise, I'll let you know if it worked

    Another excellent video i did chuckle with regards to the oil leak we've all been there. I find all these adjustments interesting someone at some stage must have spent hr upon hr sussing and writing them all down as s blueprint. Happy birthday to Debbie 🎉

      Cheers Jon, I'll pass your regards on to Debs, as you say someone sat for hours with a cup of tea and a rich tea biscuit giggling to him/her self thinking of us having all the fun trying to set them, it's a bit like a British Leyland engineer when they designed the mini, well maybe not quite that bad.
      many thanks

    I was on the DB forum for about 10 years and 90% of the problems were covered by two topics - engine starting/running and Selectamatic hydraulics. Yours starts first crank and the hydraulics are as like new so you are making it look too easy! Great job again. You’ve probably got one already but the decal for the quadrant lever is pretty cheap and just finishes it off nicely, as does the dome nut to cover the lock nuts. Good to share a 64th with two loved ones.

      Hi Andy, I can agree with your forum topics because the viewing figures for those topics are off the map, things like gearboxes and pto to a degree fade of the end of the scale compared to the hydraulics, I also think a lot of problems with hydraulics is self induced due to the lack of oil changes, water ingress and the like, there is a lot of "if it works don't touch it" mind oil is a fortune lately, If Gemma hadn't the oil at the farm for the old tractor she replaced, then I would of had a rather large bill.
      many thanks for your continued support

      I would say the biggest problem by far for the hydraulics is water ingress as you say. So many DB’s don’t have a cab and those rubber gear lever boots perish pretty easily and if that happens then working or sitting in the rain then water goes straight into the gearbox. Once there is much water in the oil then it will sit in the valve chest. The bypass and hold valves need to slide very easily and a few weeks or months sitting in watery oil and they will seize up quite quickly. Even without water ingress I’ve found the gearbox oil goes quite a caramel quality because there is so much empty space it allows a huge amount of condensation. I’m no expert on gearboxes but I would think modern gearboxes have no space for condensation like these DB’s do. Your bleed nipple is nothing compared to one of my cock-ups. I had the bypass valve out to clean, then got distracted and did other jobs and absently mindedly fired up,the engine. The jet of oil out the valve chest would have reached 100ft in the air if my garage ceiling hadn’t intercepted it at 8ft. You’ve never seen any one try to shut off a tractor as fast as me that day.

      Shane took the top off his camels humps and got a similar effect, he's managed to cover him in oil. he did say he thought it would be impossible for anyone to do any hydraulic work without getting covered or having a puddle on the floor.

    Hi Barry, have you got one about stripping the 3 way valve down and resealing it. Ive been through your playlist and cant see one. Thanks,
    Alan

    • @manfromthemist1958
      @manfromthemist1958  6 місяців тому

      Hi Alan, unfortunately not, that was a job I completed before the start of the video series, however it's not a complicated task, I removed the control lever and then the retaining plate from the top of the spool and withdraw.
      hope this helps

      Hi Shane, I'll keep my eyes open for them, I'm looking to fit the seat I've got as a temp measure so I can get to the clutch and brakes.
      Many thanks

    😮what are we after a good ❤mechanic for David brown tractors 🚜 for the hardraulics so most of the time repairs are not done properly and the tractors are put the junk 😳 many of them needs repairs from Fiji operating a David brown tractor model 885 from the year 😀 1976 one the best tractors 🚜 for sugar cane farming. 😀

      Hi Narendra, I've only visited Fiji once before, unfortunately it was at 0200hrs on a refueling stop, I remember it was still extremely hot in the middle of the night, we were on our way home from NZ, if you need a good mechanic, I'll be on the next flight.
      many thanks

      @manfromthemist1958 Hi most of my friends are in need for good hardraulic mechanics but if there is a affordable price range. We are also after some parts especially hardraulic like valve and filters ,Engine overhaul kits and the price range is very high in Fiji 🇫🇯 👌.

    • @manfromthemist1958

      Hi Narendra try Stuart at Barclel Williams in the UK you'll find him on google, he supplied the valvechest for me as well as other parts for the hyraulics.
