Re: 1412 wet brake fluid

Just looking at my supplier (Morris), they don't have a 1412 listed so I looked at a 1690 which I'm sure will have the same requirements. For the 'rear hubs' as they call it they list Liquimatic JDF which is basically a universal transmission oil, used on a huge variety of modern tractors. If tempte...

Re: Db 1210 air locking

Lift pump plunger being worn is one of the first things I would check, common issue and does cause them to die. If you're unlucky the cam lobe can be worn as well. The other big suspect is the fuel line coming from the tank to the lift pump, and blockage or bad joint that allows air to be sucked in ...

Re: Third service

There is a 'modern' way to resolve this, but it does mean spending money on a valve block. You can attach a valve to the loader that's piped into the crowd function, and with a switch fitted to the lever in the cab when you press the button it diverts oil away from the crowd function to the third se...

Re: Fitting a simple oil gauge.

Hi All When I fitted the gauge to my 1973 990 I did consider fitting a dashboard gauge. My tractor has a fuel gauge that stopped working years ago and it would have been easy to replace that with an oil pressure gauge. I decided to stick with the easier option because I need access to the rear of t...

Re: 950 compression testing

Using a scrap injector is the standard approach when people don't have the right adaptor (cheap compression testers don't always have the right dummy injectors to clamp in), you just remove the internals and find a way to get your gauge to fit - usually by welding a suitable fitting on.

Re: David Brown 1200 fluids and gearbox filler

Another method of getting the right adaptors is to weld them together, very useful when you can't get to a hydraulic supplier or they don't have what you need. Can be useful to either blank off a port - e.g for your oil filler if you can't get a proper blanking plug with the right threads, or to use...

Re: DB 1190 - Problem with Clutch Slave....no spare part

If you take the cylinder apart and use a brake hone to clean up the bore you will be able to see if it's in good condition. If it is I would just buy the seals for it then you don't need to worry about getting a cylinder or rod. If you're unlucky it might need a new cylinder but often they can be fi...

Re: Recommended Professional DB refurbisher? Advice please

Be aware, to properly refurbish a tractor (or pretty much anything of its kind) takes a huge amount of time and therefore anybody doing this as a professional will need to charge a lot of money, it will not be cheap. Don't be fooled by the ones that have had a coat of paint and the oil leaks stopped...

Re: best way to attach trailer?

Practice makes it easy.
Are you taking it on the road, or travelling long distances? If you can make the holes bigger that the pin goes through you'll gain some room for error.

Re: 950 white smoke

The place that overhauled the pump wouldn't be able to do anything about the fine adjustment of the pump to the engine, that's normally set by the person who fits it who normally puts it back where it was when it came off. In this case it's quite possible that it was not in the right place when it w...

Re: 880 Selectamatic Dynamo

I rarely mess with dynamo systems, but seem to recall that connecting the D and F terminals together and starting the engine should result in a high voltage at the D/F terminal to earth. Not a good idea to run the engine much above tickover as the voltage will get very high - the dynamo is using its...

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.
