Re: DB 780 Selectamatic radiator leak

Unless you know what you're doing it isn't a job that I suggest doing yourself. Too much heat can melt solder further down and cause big issues - though I know some people fill the radiator with water to act as a heatsink, stopping short of the filler neck.
Personally I take them to a specialist.

Re: Injection Pump Inlet Filter

I had a piece of rubber fuel hose between the fuel filters and injector pump (the original pipe leaked so rubber hose became a quick repair), this meant I could easily Tee into it with a pressure/vacuum gauge. I'm not sure what would be practical for checking the pressure without butchering the meta...

Re: Injection Pump Inlet Filter

It's surprising how well they can run when there is an issue with the lift pump or the pushrod. My 995 used to conk out sometimes and you'd have to bleed air out of it to get it to go, then it might do it again five minutes later or it might go two years without missing a beat! Drove me nuts checkin...

Re: Case 1494 Alternator

At that voltage it isn't charging, you should be seeing 14v or at least pretty close. Nothing special about a DB alternator as far as I know. Before condemning it make sure it has a good earth connection - best way is with the engine running with a few revs put your multimeter onto the alternator bo...

Re: Use of Gasket compound or not ?

Hylomar universal blue is excellent for coating paper gaskets to ensure a good seal, I don't install paper gaskets dry unless there's a specific reason to. Well seal is another tried and tested product. There are various sealants available to replace gaskets - I think it's Loctite 515 that DB starte...

Re: Power Steer Filters

I recall there being an issue with seals on a replacement power steering filter, I think it didn't have any. I think I ended up gluing some seals on (maybe from the old one?) as metal to metal didn't seem appropriate. I had to have the tractor back in use that same day so there was no option of spea...

Re: What is this implement?

Thanks for your thoughts, looks like its exact purpose is still a mystery! It must be either missing something or needs to be used in conjunction with something else as far as I can figure.

What is this implement?

Probably not anything to do with David Brown equipment, but does anybody know what this device is?

Re: Injection Pump Inlet Filter

I used silver steel as it's good quality material but unhardened. It's not going to cause excessive wear in its soft state, and is ground to the exact size with a good surface finish so only needs making to length. Cam wear is certainly an issue and I would never use anything hard - my 995 has a wor...

Re: Injection Pump Inlet Filter

It does sound possible that there's a problem between the filter and injector pump, though it is rare. As said, pay attention when you undo the fitting on the pump, make sure everything is very clean and you should be fine. Worth checking as you've made no mention of it is the lift pump push rod and...

Re: 90 series power steering problem

If it was my machine I'd be draining out all the ATF from the system (including emptying the ram) and running it on the same oil as the engine uses so that no harm will be done if it ends up in the engine.

Re: david brown 900

You can get oil coming out of the exhaust when it hasn't bedded in, the other possibility is that an inlet seal or oil ring has been fitted wrong. Give the tractor some hard work - a heavy trailer on hills is good, use engine braking to slow it down when going down hill. Avoid very high revs and avo...

Re: Manifold flange removal.

Left handed drill bits and stud extractors are useless on seized items. If it's rusted in place tight enough to snap in the first place then the extractor will also snap. Once this happens you're in trouble, a broken extractor in a hole is difficult to deal with. Where they are effective is when the...

Re: Manifold flange removal.

It's impossible to say whether they'll come off without breaking. Sometimes it's obvious that they're too corroded, often you can't tell until you've tried it. Every now and then things like this can come apart with ease, against all expectations. If you get any movement on the nuts work them back a...

Re: Where to order loader ram seal kit from (UK)?

For ram seals I always take them apart and go to a place which supplies bearings, seals etc. A decent place usually has them on the shelf, or there the next day if they're an unusual size.
