Re: Spun bearing on 990

To test the clearance between the crank and new bearings feeling for play isn't suitable, plastigauge isn't expensive and tells you what's what. Check in a couple of different positions where possible to check for being out of round. https://www.ebay.co.uk/i/173609836432?chn=ps[url] [/url] I too wou...

Re: Leak in catch knob/ramshaft cover- 880 Implematic

Metal spraying is a very, very useful process that can repair many kinds of worn parts to new (if not better) condition. However, on a pin like this I wouldn't be doing that, it's such a straightforward machining job that it would be quicker and easier to make it from fresh material. Welding produce...

Re: DB 1200

The stop may be easy enough to fix, but if the pump isn't delivering fuel to each injector then I think your best bet is to find somewhere that repairs injector pumps, they're specialist equipment - one of the few things on a DB that isn't a straightforward DIY job. While you're at it send the injec...

Re: 885 draw bar

Looks like those used on many other models (including the 995) - I recently had to replace one which snapped and found that there's usually a few available on eBay, though some of the prices are on the high side but they are available. It may be a little harder getting one to your location, but you ...

Re: 1967 990 engine block

There are different methods available to weld or braze cast iron. One method - which most seem to think is the only method - is to heat it up, weld it and cool slowly which is obviously a lot of hassle, particularly with an engine block. It can be welded cold with a stick welder using the correct ro...

Re: Front loader stuck

You are going to have to give a lot more information...

How is the loader plumbed in, does it have its own valve block? What model tractor is it on? Is the linkage that controls the loader working correctly?

Some photos showing the system would be a starting point.

Re: 1394 steering fluid change

I'd certainly be changing the filter, they're a bit of a nuisance which means that it probably won't have been done for twenty years. I've seen them collapse through old age.

Re: Hydraulic take off on db 25

Presumably it would be OK to flush these old machines out with a cheap, thin and easily available mineral oil. Nowhere near as extreme as diesel but probably more effective than 90 weight oil?

Re: Spun bearing on 990

Obviously your crank is not very healthy. If you can see rings round any of the journals it should be reground to make things right. However, for an engine that's only doing fairly easy work on a small scale you can sometimes get away with spending some time with strips of very fine emery to polish ...

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.
