Re: 950 implematic exactor coupling

I can't help on why you keep getting the wrong size, but I also question why not change to the regular, modern quick coupler? It's a good system that's also compatible with almost every other implement you're likely to find and probably easiest and cheapest. Of course, if you're running a show machi...

Re: Compression test

Yes, injectors can be adapted for this purpose - though if your injectors have been reconditioned I'd not be messing around with them! It sounds like you need a better compression test kit. The cheaper (and much more common ones) are for attaching into the glow plug holes which most engines have, bu...

Re: New radiator

That price is quite reasonable for a re-core - certainly a lot cheaper than I've ever had one done in my area. I've no experience of the cheap ones that are available for David Browns but unless the cost of a re-core was very high I would choose that option over getting a radiator of unknown quality...

Re: David Brown/Case 995 Starting Problem

It sounds like your solenoid is tired, the contacts inside will be burnt and corroded. When the terminal was turning as you tried to remove the nut it'll have moved things enough to make it work again, at least for now. Normally it's possible to take the solenoid apart if you are prepared to unsolde...

Re: Nylon Filter in the By-pass Valve Plunger

It's down as a maintenance/service task in the manual for my 995 as well. Always thought that the paper suction filter should do enough and to leave well enough alone, but it is certainly in the manual as part of the service routine.

Re: David Brown 770

You've a good chance that the engine is seized from having water standing in it. With the gearbox in neutral put a socket and breaker bar on the crankshaft pulley nut and see if you can get the engine to turn by working it back and forth, you may be lucky. Another method to get them moving is to put...

Re: Pulling power

'95 Ford 7840 SLE with about 7000 hours, a great little tractor that pulls 12t grain/muck trailers all day as well as brand new 140/175hp fords do, great tractors that seem to be underrated by many. But DB's are also very capable and again I think people under estimate what they're capable of doing ...

Re: Oil prerssure

I had an engine apart a couple of years ago and it wouldn't develop any oil pressure when cranking. The solution was simply that it needed priming by putting oil into the gallery/filter housing (at the pressure switch or blanking plug as I recall) using an oil can. It can happen when an engine is sa...

Re: Pulling power

I think it would manage it fine provided you aren't on very steep or wet land, I've done tanking with a 2000g tanker behind a 100hp Ford which was within its capabilities.

Re: Engine rebuild

Your breathing from the crankcase does not sound to be excessive so isn't a reason to rebuild. Tell me more about the starting problems. If the compression is suspected to be low I suggest doing a compression test before pulling anything apart - you don't want to strip the whole engine to find that ...

Re: 900 front axle surprise

An engineering shop would not charge too much to do the machining work if your lathe is too small. Depends where you are! I know a couple of places locally, the one that's any good were charging £50 per hour a while ago and I'm sure it's increased since then. And they're not greedy, various running...

Re: 1594 Hydra starting problems - smoke but no fire.

I have thought for years about building an injector tester, I wonder if a grease gun would produce enough pressure? I would need to make an adapter to the injector, pressure gauge and perhaps valve. A quick google search shows you can get a tester for around $100 usd so that is tempting. The local ...

Re: Snapped drawbar - anyone ever seen this before?

the fact that you run on the short setting would mean less springy and more ridgid plus the fact it had been welded! i have just purchased a 1690t and the draw bar was snapped off, not been welded but i would guess it may have been abused! I find it surprising that any amount of abuse will cause th...

Re: 1594 Hydra starting problems - smoke but no fire.

Lapping is making parts fit together properly by removing very small amounts of material so you get a good seal. As you don't sound to have anyone decent in your area I think I'd be talking to injector places which aren't local and posting them each way, it would add a little time but means you can ...

Re: Front tyres for loader

My disliking of the four wheeled, turntable trailers is partly due to not being easy to reverse and also because they don't apply any weight to the tractor. No drawbar weight does of course help hitching them up when a pickup hitch isn't on the tractor, but sometimes it is nice to have some of the w...
