Re: 880 Selectamatic Possible Overheat

Your temperatures sound fine for an engine that isn't working, your problem is electrical. Could be a faulty gauge, faulty sender or that the two aren't correct for each other.

Re: Witch david brown engine have i got

Bit of a tricky one unless someone happens to recognise the numbers. It's probably a Case engine - it's possible that they used their 188 diesel for the backhoes, I'm not sure - but David Brown engines were used in some of their crawlers. I know a 4WD 580 that has a turbo engine, it's a Case one. I ...

Re: Tyre Swap

The angle iron is just that, a piece of angle iron. Approximately 2 x 2" and about 3 inches long with the corners rounded off so they can't dig into the tyre, set it with one edge going between the rim and tyre and hit it hard to push it between the tyre and rim and it will push the tyre back. May t...

Re: Tyre Swap

Oh I would never remove the wheel of a tractor to change a tyre. Even a DB rear wheel and tyre is a heavy item that you would not want to have to pick up if laid on the floor, and many of the ones I change are much bigger. Often the tyre itself is too much for one person to stand up, but I can fit t...

Re: Tyre Swap

It's simple when you know and understand what you're doing - I fit a lot of tyres. But the first ones you do are going to be a bit struggle as you will not have the right technique or full understanding of how it needs to be done and something simple like not having the tyre in the well will make it...

Re: 1967 David brown 990 very slow to tip trailer.

I would first plug a pressure gauge into the trailer tipping port and check that you have full pressure. To lift the trailer with a full load requires high pressure, as you are having to shovel some of the muck off first it's quite possible that your tractor is not generating enough oil pressure. Oi...

Re: 1200 brakes

I'm not sure if it's practical to only slide it out partway as I'd not want to leave it hanging like that, but if you did the whole thing would try to spin round so the heaviest part was at the bottom so you'd still have a struggle. There's a good chance that you'll want to replace the oil seals on ...

Re: 1200 brakes

Have you tied the diff lock pedal down? It won't stop them coming off but will make it very hard to get back together if you don't do it. You might have 3 bolts to remove for the cab mount, I assume these are out? With the brake shoes backed off and all the bolts out there's nothing left to hold it ...

Re: piston rings and bearing shells

I've a DB engine that takes a good 6 seconds to build oil pressure, but the pressure it has is good and it does not concern me. Putting a pressure gauge on your engine to see what the pressure is is the first thing to do, if it has good pressure when hot then I'd not be worried. If the pressure is o...

Re: Help if possible please.

David, Here you go. Looks like five bolts each side. Two back near the cab, one near the front of the tractor also holding the piece that protects the front end of the tractor, and two a little further back. IMG_1372.JPG IMG_1373.JPG IMG_1374.JPG IMG_1375.JPG IMG_1376.JPG IMG_1377.jpeg

Re: flushing out transmission/Hydraulics

Cleaning out loader rams. If they're single acting just have them all the way in - loader sat on the ground. For double acting you want to work it through the full stroke to get both sides empty. I usually lift the loader all the way up, drain the oil and use gravity to lower the loader. You suck ai...

Re: flushing out transmission/Hydraulics

Use the diesel flush. It's a pretty cheap method and is very effective, far better at removing filth than oil. You could do it twice if you wanted, but it would have to be very, very bad to need that. I've seen where clean oil gets instantly contaminated and looked like used engine oil, one diesel f...

Re: Help if possible please.

That was very kind of you to post those photos. Thank you. But I am certain that the loader fitted to the 990 I am talking about was originally for an 885. According to my spares books the frame for the loader of an 800 series tractor was quite a bit different from all the others. It was shorter (o...
