My David Brown 996 project

Post by bean » Sun Jan 16, 2022 11:18 am

Hi everyone, this is my first tractor. I picked it up as a bit of a project. I have been keeping an eye out for a David Brown locally and i had hoped i could pick up a 995/996 or a 1210 at some point. Any that came up that were well priced and had a loader seemed to sell within a day or two. Eventaully i found this 996 and went to see it straght away.

It has sat for a long time and not done much work for years other than some PTO powered log splitting. Fast forward a week and it got delivered. I was told the starter was dead so tow starting it was the only option for now. It started really easy with a short tow.

First job was to get it all blasted off with a pressure washer and a degrease also using a heavy duty degreaser in a snow foam lance.

Next job was to remove the starter and get the battery on charge. I thens tripped the starter motor down, cleaned everything up then tested it with a battery and it seemed to be working fine.

Image20220115_120418 by Bean Beano, on Flickr

I refitted it to the tractor

Image20220115_165615 by Bean Beano, on Flickr

It wouldnt start of the key (whihc looks like someone has been at this before) but it started with a spanner across the starter without much trouble so hopefully it will be a good starter.

I then thought i best check the air filter if ive now just about got a running tractor.

It was discusting and the wire mesh filter was covered in old grass and dirt also, im noit sure if the wire mesh filter will be salvagable, ive had a look for a new one but they dont seem to be easy to find like other items. The oil bath needs a good clean out and i plan to remove the full air box setup and give it a really good clean and degrease then its right.

Parked up where it will be living. Hoping to extend the roof sheets over it before long which will help keep the rain off.

ImageIMG-20220114-WA0006 by Bean Beano, on Flickr

Image20220114_150650 by Bean Beano, on Flickr

Looks like it had a wasp nest in it at some point

Image20220114_163358 by Bean Beano, on Flickr

When the tractor arrived it was missing the side window on the right side of the tractor as you sit in it which is a bit of a shame as it was not missing when we went to view it, so it looks like it fell out in transit. So i need to source one of those. So far ive ive ordered alot of service items for the machine from Agriline which seems to arrive wuickly and there website is easy to use. Ive ordered a few parts off ebay also. I will have to get to know all the places where to get parts for these.

I thought i would try and keep this thread updated as i go as it will be a nice record of what work has been completed as i work through the tractor.
Anything you guys can spot in the pictures or any expert knowledge will be much apopreciated as i am certainly not an expert on tractors. I have a copy of the manual so i have been gonig through that which will be a good help.

I best get back to it.

Thanks Moose, i will keep the updates coming. Im off work this week so ive got plenty time to work on it.

I had the bonnet off yesterday so i could remove the air box to clean it out.

Image20220116_164545 by Bean Beano, on Flickr

The oil bath had fibre glass on the bottom of it, as it has some pin holes in it. I might have to replace this, ive looked for a new one but cant see any available so second hand might be an option if it doesnt weld up ok.

Image20220116_121323 by Bean Beano, on Flickr

I also got most of the grease points done. I couldnt see one of the clutch cross shafts points on the near side. One on the back end was blocked up which i couldnt get and one i couldnt reach with the grease gun.

one side has this odd tyre on and the wheel is very badly cracked, so im going to replace the rime and tyre. Agriline seem to have the best price i can find for a wheel and tyre already fitted in 7.50 x16 at £106.80 so i will order one of those shortly.

Today im going to continue cleaning out the air box and the oil bath. It looks like two of the wire mesh filters had been fitted, one in the oil bath and one in the bottom of the air box. I thought only one should be fitted, is this right? The one in the air box seems in tight, i left it soaking in hot deagreaser over night so im hoping it will come out easier now.

This was the state of the pipe to the air box after soaking in degreaser all night.

Image20220117_105702 by Bean Beano, on Flickr

The oil bath bowl after a clean up. you can see the small holes in it.

Image20220117_113338 by Bean Beano, on Flickr

Welded the holes up

Image20220117_142538 by Bean Beano, on Flickr

and a quick spray just to tidy it up a bit for now.

Image20220117_144532 by Bean Beano, on Flickr

The air box was cleaned and cleaned until it was as good as i could get it. then i gavce it a quick spray, nothing fancy but it will do for now.

Image20220117_144512 by Bean Beano, on Flickr

The exhaust had seen better days.

Image20220117_123041 by Bean Beano, on Flickr

Image20220117_123106 by Bean Beano, on Flickr

Image20220117_123101 by Bean Beano, on Flickr

I got this cleaned up then welded the holes up and gave it a coat of high temp paint to tidy it up a bit.

Tomorrows job will be refitting the air box and oil bath, filling with oil and maybe removing the power steering pump to make a start on replacing the seals in it, but theres plenty other bits to do. I was about to order the new wheels and tyre i need but its out of stock now so that will have to wait.

I believe the upper wire mesh filter is not removable so only the bottom one can be removed.

Have you also checked out Barclay Williams and David Brown Parts for your replacement parts? If they can't help then there are a number of breakers to try, e.g. Richard Pocock.

Keep up the good work!

David

Thanks David. I have heard people mention them and reconmend them and ive checked out their websites. I like the convienence of ordering online as i am often ordering things late at night. If im struggeling for anything i will give them a ring. At some point i will probably rebuild the rams on the loader and ive not seen those seal kits listed anywhere so i will give one of those places a ring when the time comes.

Ive been tinkering away most of the week on the 996 doing bits and bobs amoungst some other jobs.

Oil bath refilled and back on the tractor.

Image20220118_111430 by Bean Beano, on Flickr

Image20220118_112956 by Bean Beano, on Flickr

The lift pump needed a good clean out.

Image20220118_115041 by Bean Beano, on Flickr

This sludge was waiting inside it.

Image20220118_115131 by Bean Beano, on Flickr

Next was the fuel filters.

Image20220118_120538 by Bean Beano, on Flickr

and in the bottom of them.

Image20220118_120813 by Bean Beano, on Flickr

and the new ones fitted.

Image2022-01-22_08-56-03 by Bean Beano, on Flickr

I thought i would check the oil pressure while i was working on the wiring behind the dash incase the sensor wasnt working right.

Image2022-01-20_09-31-12 by Bean Beano, on Flickr

Great oil pressure so that was good news.

My new wheel and tyre turned up

Image20220121_155811 by Bean Beano, on Flickr

after a quick clean up, light sand and some epoxy primer.

Image20220121_165057 by Bean Beano, on Flickr

Then after a few coats.

Image20220121_172901 by Bean Beano, on Flickr

I noticed this the other day, a hydraulic fitting fitted onto the oil filler pipe.

Image20220121_152034 by Bean Beano, on Flickr

I also put a flap on the exhaust as i didnt want rain getting in before the roof sheets are extended to cover the tractor up.

Image2022-01-22_09-09-28 by Bean Beano, on Flickr

Ive ordered a heap of bits and bobs to get some of the wiring sorted for headlights and for things like the washer bottle, horn, rear number plate light. I also need to replace the brown wire coming from the starter motor as someone has done this in the past behind the dash but the wire isnt thick enough so i plan to get that out and do it right.

Today my plan is to get the welded out and fix a big wheel barrow frame with some box section and then try to weld some nuts onto the snapped off wheel bolts in the front hub on the side im replacing the wheel.

Given the state of the fuel and air filters are you planning to change the transmission/hydraulic oil and filter? For the sake of a filter and a few gallons of oil it would definitely be worth doing in my opinion. It could well prevent hydraulic issues later on.

By the way, the hydraulic fitting on the PTO housing is an oil return to the shared transmission/hydraulic oil volume. Normally, return oil should be piped back into the tractors internal lubrication system via the ‘camels hump’ to ensure lubrication of the transmission and PTO gears but your loader is probably using this connection. Hence why this fitting has been added.

For expert advice on DB hydraulics please post in the General Discussion.

Yes i plan on continuing going over the full machine servicing everything. I have alot of the parts already and i have bought 25L of 10w30 for the back end. I just havent got to the transmission filter yet, ive only had the tractor a week so far.
Your right the loader returns into the return on the camels hump. I have read through the manual and understand there is another return on the 3 way valve which should be used rather than this setup on the oil filler. My plan at some point would be to add some sort of connection to this return behind the 3 way valve but i would want it mounted onto a plate not just flopping around, then i would have the option to hook it up to the log splitter or anything else in the future. Thanks for the reply :)

Not many more updates really. I got a new rad cap fitted as the old one was in poor condition

Image2022-01-25_07-32-58 by Bean Beano, on Flickr

My new tacho arrived so i fitted that and now have a working rpm gauge.

Part number below for VQ cab tractor

A few more updates.

The 2 snapped off wheels bolts were drilled into

Image20220128_153624 by Bean Beano, on Flickr

then nuts were welded onto them with the welder cranked up to get everything nice and hot.

Image20220128_154712 by Bean Beano, on Flickr

I left them to cool and gave them a spray from the back side and they ran straight out with the impact gun.

Image20220128_155558 by Bean Beano, on Flickr

New wheel fitted

Image20220128_165723 by Bean Beano, on Flickr

Image20220128_165709 by Bean Beano, on Flickr

The next job was draining the gearbox oil

Image20220129_154709 by Bean Beano, on Flickr

I also drained it from the big nut further back, i couldnt find any other points to drain it from.
The oil that came out didnt look too bad, certainly not as bad as i was expecting.

There was this gunge in the bottom of the filter bowl though.

Image20220129_160056 by Bean Beano, on Flickr

There was no filter fitted however so i am also missing the strainer / bypass valve.

This bolt was also wedged next to the pick up pipe.

Image20220129_160329 by Bean Beano, on Flickr

I loosened the pipe off and got the bolt out

Image20220129_160506 by Bean Beano, on Flickr

Image20220129_160502 by Bean Beano, on Flickr

The bolt must have been dropped in when someone had the selector cover off. Someone had cut this access hole in the past.

Image2022-02-02_08-59-20 by Bean Beano, on Flickr

I had another go at adjusting the clutch but i think it is sticking a bit when disengaging. So i took the inspection cover off for a look. I wasnt really sure what i was looking for as ive no experience with tractor clutches previously, just cars. Heres a few pictures anyway

Image20220128_134906 by Bean Beano, on Flickr

Image20220128_135023 by Bean Beano, on Flickr

Image20220128_135037 by Bean Beano, on Flickr

I spotted this on the lift pump side of the tractor, i had recently greased the grease fitting but im guessing there should be a small tube which goes to the clutch cross shaft here?

Image20220128_135048 by Bean Beano, on Flickr

I did seem to get the clutch going into gear and ranges better but im not convinced its quite right. I was told the tractor had sat for long periods so maybe this has made the clutch sticky. Im just going to carry on fixing everything up and maybe i can find someone local who can see what they think of the clutch at some point. I did drain the old clutch fluid out and refill with LHM+ then bled it through. I have also sucked the old brake fluid out and replaced with LHM as it was low, ive not bled the brakes yet but i will do shortly.

Cheers DRM i had spotted that. A local guy down the road from me should have one for me, hes just been too busy to get at it yet. Im hoping tomorrow or Friday he will have it for me fingers crossed. If he doesnt get round to it i may order that one. The new ones are almost £200 and that seems far too much money to me for what it is. Also ive managed to track down a rear panel complete with all glass so i should be getting that on Friday and hopefully a few other bits. It will likely need a bit of welding but i dont mind remaking some smaller sections of it.

Ive not got much else done really.

I straightened part of the front panel up a bit. Not sure how good i will be able to get this but it still needs plenty of the dented areas knocked out.

Image20220205_151052 by Bean Beano, on Flickr

Image20220205_151056 by Bean Beano, on Flickr

I got new headlight rubber mountings and a pair of headlights with H4 bulbs rather than the sealed beam units. I got these both fitted, everything takes longer with seized bolts and things snapping off.

Image2022-02-09_09-59-45 by Bean Beano, on Flickr

I still need to remake the loom for the headlights and test if the horn wiring is still decent as i connected it up and it doesnt seem to be working. I ordered the right colour and size wire from a seller on ebay called incardesignltd he sells all the right coloured wire if anyone wants to repair their loom with the correct colours.

Ive started removing part of the heater console in the roof. Ive cleaned up the piece on the right side and the vents.

Image20220205_163322 by Bean Beano, on Flickr

It was ready for a good clean out.

On the other side i havent worked out how to remove the heater control knob to the left of the switch so i havent managed to get this off yet.

Image20220205_163317 by Bean Beano, on Flickr

I have tried to drop the full panel down from the roof and i removed all the screws but it didnt want to release so i decided to leave it for now rather than risk snapping it.

Also cleaned the interior light up and found a LED bulb which ive managed to fit, i wasnt sure what bulb it took as there wasnt an old one inside the light and i couldnt find it in the electrical manual. I found a loose black wire which looked in really bad condition behind these panels but i am unsure what it should have been connected to yet without getting a better look.

I have been taking the switchs apart as they had very bad connections in them. They were full of dirt, and the copper parts were corroded. After a good clean up i put them in a hot Bilt hamber deox C sollution and it eats away at the corrosion.

Image20220213_121037 by Bean Beano, on Flickr

Image20220213_123615 by Bean Beano, on Flickr

Ive done this with the leveling arm and other parts too but i havent painted them up yet.

I managed to get hold of a gear oil filter screen with bypass valve from a local guy.

Image20220217_163404 by Bean Beano, on Flickr

and in the new filter.

Image20220217_163435 by Bean Beano, on Flickr

I removed the feed and return line for the loader to get as much of the old oil out as i could, i also shortened the return as it was hanging down and too long. The feed was also ran poorly hanging down so i ran it over the draw bar frame so it doesnt hang down.

I put some Neodymium Disc Magnets at the base of the filter bowl just to help keep anything magnetic at the bottom away from the pickup and installed a new gasket.

I made a start getting the hydraulic pump off. i ended up removing the alternator to get at the rear bolt and removing the bolts on the lift pump to get enough access.

Image20220225_155703 by Bean Beano, on Flickr

The pump stripped down and starting to replace all the seals

Image20220227_125002 by Bean Beano, on Flickr

The bearing sleaves didnt look in very good condition, but the power steering was still working great. I looked into replacing them but this doesnt seem possible due to the clearances involved which is a shame. So i will just have to see how it goes and replace it in the future if i get any issues. Unless anyone rebuilds them?

Cleaning the reservoir cover up

Image20220227_185201 by Bean Beano, on Flickr

A bit of paint to tidy it up.

Image20220228_162651 by Bean Beano, on Flickr

Image20220228_221832 by Bean Beano, on Flickr

I realised that the gasket was missing when i removed the pump but i managed to find one on ebay from SPSParts

Image20220304_144210 by Bean Beano, on Flickr

And the pump refitted with the new o rings and seals fitted. I also fitted a filter as it was missing which i pretty much expected at this point. The filter did come with some O rings but i couldnt see where they would go. I checked the workshop manual and the exploded diagram showed all the seals which i fitted so i just assumed they were maybe for a difference tractor which uses the same filter setup.

Image20220304_163448 by Bean Beano, on Flickr

I got it filled up with 15w40 engine oil. I also fitted a new paper gasket to the lift pump. Next job is refit the alternator but i might give it a clean out first.

This is the rear panel i managed to get hold of.

Image20220228_162734 by Bean Beano, on Flickr

Behind it is the side window i was missing and also some door glass i was given as spares.
