RE: Connecting an LQ 12 loader

Hi, the threaded fitting would normally be the pressure fitting (connected to threaded high pressure pipes) connected to the tractor as ollek describes. The smooth brass fitting being the return, fitted to wider low pressure pipe and usually secured with a 'Jubilee clip'. I think the brass fitting h...

RE: LS9 loader for 990, paint and emblam

There seemed to have been a few version of what was fitted to these loaders. Anything that says David Brown would be fine, although many do not have anything.

RE: Re: RE: 1394 injectors removal

Pouring oil in is probably a waste of time (and oil), as it would just sit on top of the water that is already there.

RE: Re: RE: 1394 injectors removal

Hi, 1000 posts but probably little useful information said ! If there was an easy way then you would be told. I'd suggest you look at this link: http://www.dbtc.co.uk/index.php?name=PNphpBB2&file=viewtopic&p=7182773 It is worth doing the job properly. I'd consider fitting new rings, big end shells a...

RE: Re: RE: 1394 injectors removal

Hi, if it is genuinely seized then the only way is to remove the cylinder head. If you try to tow it will probably be a waste of time and you will possibly break something. The cylinder head will then still have to be removed. Gently towing could be worth a try but will only be successful if the eng...

RE: Re: RE: 1394 injectors removal

Hi, turning the PTO will be a waste of time. The pressure needs to be direct on the pistons, or via the starter motor. Removing the cylinder head and tapping the pistons is the most effective way.

RE: 1394 injectors removal

Hi, I meant sort of rotating them slightly, but only a fraction of a degree as they will be limited by the studs. The best thing may be to lever up with a crowbar whilst tapping the shoulder at the same time to free them. They will not be as stuck as you may imagine.

RE: 1394 injectors removal

Hi, giving the shoulders of the injectors a good clout with a hammer may help to 'break' the seal. Ideally using a copper hammer (possibly). Obviously don't tap them too far.

RE: 1983 david brown 1190.

Hi, yes I think it is above the 3-way valve situated under the cab (assuming it has one). It will probably thus be hard to get to and may snap off / get rounded if you try to remove.

RE: 990 implematic battery tray

Most of the DB's I have seen have had the battery sat on a piece of rubber mat, about the size of the battery base, or at least a piece of wood (about 1/4" thick). This would stabilise the battery and prevent it rubbing against the casting. The clamp would prevent the battery rocking into the radiat...

RE: Re: RE: HAND BRAKE 990 Selectamatic

Hi, some of the DB handbrakes have a hole that allows a small punch to be inserted, allowing the pawl to be pushed out. Such a hole could be (retro) drilled. Other type may have a grease nipple fitted to prevent sticking. The diesel may help but WD40 may be better. What you may have to do is use a p...

RE: Re: RE: HAND BRAKE 990 Selectamatic

In many situations of DB repair you may have to improvise by cutting down and/or bending a spanner in order to make it fit the awkward bolt or nut in question.

RE: Pump

This could be a good video to watch:

It apparently explains the full strip down and re-seal of a CAV pump (1hr long).

RE: 25D Paint

Hi, I certainly wasn't around in the 1950's but I don't think the DB company would employ people to polish newly painted tractors that were destined to work on a farm. The same goes for the nuts and brass parts. The priority would be to get them painted to a high standard, but no more. Some tractors...
