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 th...

Fitting a simple oil gauge.

Hi GuysBack in February I got involved in a debate relating to engine oil pressure and came to the conclusion that I needed to monitor the oil pressure with a simple gauge. It seemed like a good idea to share my experience of fitting the gauge. A simple 20minute job, finding the bits took longer. Pl...

Re: Tyre Swap

Hi Guys Thanks for the feedback. Cobbadog you are obviously working towards a higher standard than I do. Those wheels look show quality which I am sure is no accident. My trouble is that my 990 is most definitely a working tractor and the farm budget cannot justify shot blasting and such fine paintw...

Re: Tyre Swap

Hi and thanks for all the useful information. I have seen it done before but didn't ask questions. You have mentioned 'angle iron' a couple of times to remove the tyre. For me angle iron is that L shaped piece of structural steel. I suspect that is not what you mean. I have crow bars, and other clea...

Tyre Swap

Hi Having seen rear tyre swaps on U Tube where they make it look relatively easy, I was thinking for swapping over my bald DB990 rear tyres. The old tyres have more crevices than an Iceland glacier. The newer tyres are merely worn down to 30% tread. Have any of you swapped tyres. Where do you get ty...

Re: piston rings and bearing shells

Hi Next step is to find and fit the pressure gauge. Davidbrownparts.com couldn't supply the parts, they only supply standard parts and the add on gauge was never a standard fit. So what have others done. I wanted something mounted onto the engine block so that I could remove the dash to do other wor...

Re: piston rings and bearing shells

Hi All Thanks for the comments. Pressure Gauge is a good next step. See where that leads. As for replacing the crankshaft bearings, your replies are pretty much as I had expected. I'm not to keen on spending to much money on the engine because the gearbox has a problem in second gear where it someti...

piston rings and bearing shells

Hi I have a 990 Selectamatic 1973. The engine works well enough for the age and hours worked, about 14K varied and often not that hard hours. However I notice that the oil pressure takes about 6 seconds to switch out the light when the engine starts from cold. Second the engine always smokes noticab...

Re: Voltage Regulator / Dynamo

Hi Voltage Regulator now working as it should. Regulates the voltage to 13.4volts when running over 1100 rmp, and about 13.2V with all lights on. Not sure where the fault was but something must have been wrong in the wiring or maybe the regulator components were just sticky from sitting in a box on ...

Re: Voltage Regulator / Dynamo

Thanks everybody for your ideas. The online manuals for the electrical system is very useful. It's pretty easy to follow and doesn't need any test gear other than a multimeter. Basically they are looking for electrical wiring faults. Checking my wiring was the next step in the plan. The supplier has...

Re: Voltage Regulator / Dynamo

Hi Gard Thanks for the offer of a set up manual. I'll PM you for that. Phil, thanks for the pointer to the manual. Cobbadog Faulty unit was my thought too and I have contacted the supplier. I suspect as a supplier they will either say return it or not our fault. I don't expect that much technical su...

Voltage Regulator / Dynamo

Hi 1973 David Brown 990 fitted with Dynamo. My problem is that I noticed the battery wasn't being charged and I had to pop it on the charger from time to time. Measured the voltage on the battery with the engine running, typically 12.2V and that didn't seem to rise with engine speed. In the past it ...

Re: Bullet Crimp Size

Hi Thanks to all for your good ideas. I was looking for the original items because they can be plugged and unplugged which can be convenient, also where I am looking to refit the wires the existing bullet crimps were still in good condition so it would be nice to replace like for like. I had seen th...

Re: 885 metal-parts found in the hydralic filter

Hi Lasse You have exactly the same problem I my 990 (1973). I had to drain the oil about 4 or 5 years ago and found the same bits in the filter bowl. I think I found 5 or 6 of those brass wear strips. The gear box has had a problem with engaging 2nd gear for at least 10 years so I assume that the ci...

Bullet Crimp Size

Hi The wiring on my 1973 DB 990 uses the standard Bullet Crimps that push fit into the steel and rubber coated joints. I know they aren't all that type or size but many are. Where can I get alternatives to repair the wiring as I am in the process of refitting head lamps and a ploughing light. I coul...
