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...

Re: Injection Pump Inlet Filter

Hi Guys I thought that I would update you on the outcome of my investigation. The filter was easier to remove than feared. First removed supply pipe. Then unscrewed adapter from pump. It has a copper washer for sealing. Carefully lift out the spring, note that it has a plug insert on the bottom end....

Re: Injection Pump Inlet Filter

Hi All Thanks for the support. I will check the fuel return pipe for blockages. Hadn't thought of that so far. The filters are bought from our local parts store who specialise in tractors and construction equipment so I have no worries on that point. Same place for the last 30 years for all the trac...

Re: Injection Pump Inlet Filter

Hi db2d. Thanks for the feedback on removing the filter. My concern is that when I pull the filter out, there will be other bits that come with it or fall back inside misaligned. I agree with what you say about the filter being unlikely to be the fault but after replacing the pump, filters and seals...

Injection Pump Inlet Filter

Hi DB990 has a problem with fuel starvation. Difficult to start, it needs bleeding which in itself takes longer than usual. The tractor only runs idle for about 15 minutes before the fuel runs out and needs bleeding again. I have narrowed this down to a problem in the injection pump. There is I beli...

Re: VAT Receipt for parts

Hi Guys Thanks for your feedback. I had thought of creating a receipt (I'm in the UK) but as you suggest including a line stating that it was 'Based on Quote and Bank Payment'. I would then have kept the emails and other evidence for an inspection if required. I don't think I would have claimed the ...

Re: VAT Receipt for parts

Happy to say that the supplier has now emailed a copy of the receipt so alls well that ends well.
It did take a little persistance butI guess we all have bad days.

As they would say on Ebay

VAT Receipt for parts

Hi I have a DB 990 for working on the small farm. I recently bought spare parts for the Hydraulic Control lever and brake pawl. Phone up the supplier, passed over card details and promptly received the parts. Great so far, would happily use this supplier again except! There was no receipt or Invoice...

Re: Hydraulic Control Lever Broken

Hi Thanks for the information. I finished reassembly today and it all went well. Disassembly was helped by knowing there were three bolts to find. The hard to get at one isn't obvious. In my case the control lever was broken so I just too the control panel off which made it easier to get to. Same wh...
