Re: Thread pitches on early DB 800 series

So when did they stop using BSW threads on most parts, I have a 1965 990 implematic. I have used unified thread bolts from the local hardware store and they seem to fit but don't think I have looked close enough to see the difference, is it the angle of the threads that is different?

Re: 990 oil in coolant

I also had the experience of coolant in the oil (faulty oil/water pump on a motorcycle). I agree with a previous post that it is very difficult to get the coolant system really clean, I flushed cooling system every few days for months, I suspect if I opened the system there would still be some scumm...

Re: 1965 David Brown 990 Backhoe loader lost all drive

I know what you mean, I hate it when I cannot find anything wrong, even if it works when back togather. Did you say there was a circlip out of place when you first took it apart?

Re: 1965 David Brown 990 Backhoe loader lost all drive

I might be missing something but I think those nuts are supposed to get loose and fall out as the bolts around the perimeter are tightened down.

Re: 1965 David Brown 990 Backhoe loader lost all drive

From an earlier post it seems like the transmission is working at least to some extent "turning the Muff shaft rotates the rear wheels" The clutch plates are intact I am no expert but I wonder if the problem could be someplace between the clutch pedal and throw out bearing. The actual movement at th...

Re: Fuel Tank problems 990

I had a similar issue, In my case it was the fuel shutoff valve, which I bypassed, never have gotten around to replacing it

Re: Is power steering needed for a front loader?

When I needed a loader for my 990, I put a "loader wanted" ad in the local Ag paper and found one on a farm 1/2 hr away. It needed a little work but the price was right. I leave it on most of the time but do like the extra space in the tight stuff. I have gotten used to how it protects the front tin...

RE: 880 Lift strength

I don'y know much about the selectamatic but agree with bedwards1966 and erkki, it seems if there is pressure it must be a problem in the 3 way valve, any chance the 3rd tipping valve is a little open? Perhaps a bad seal in there?

RE: 995 play between spindle and steering arm

Jazo, That is interesting, if I understand you correctly that must be a pretty tricky job of welding and grinding inside the steering arm to get it to fit back together. Beyond my skills with a welder I am afraid.

RE: 995 play between spindle and steering arm

Thanks for the comments on your experience. You are correct about the loctite, the #660 for large gaps only goes up to 0.5 mm, they publish a strength of 2490 psi. I also looked up JB weld they claim 3960 psi and it is a steel filled epoxy so will cure in any width of gap. Both these materials are p...

RE: 995 play between spindle and steering arm

I have nothing against welding as bedwards1966 suggests, I have seen it done. I would be be tempted to try a slightly less permanent fix, basically a glue that can removed with some gentle heat. Locktite makes some adhesive for large gaps or a high strength epoxy like J-B weld. If there was enough r...

RE: 990 front axle spindle play

In my case it was wheel bearings, obvious when hub cap number 32 was removed, also the bushings #11 were worn, guess I was lucky the splines were OK.

LS9 loader for 990, paint and emblam

I had to take the loader arms off for some welding and decided to paint them, they had been brown but I had some white paint left from the tractor so that is what went on them. Anybody have any suggestion on a suitable David Brown emblam? I guess I could buy a tractor emblam and cut off the tractor ...

You could try your local case dealer but I have often had better luck bringing the old parts to a local hydraulic repair shop

I have a 990 that breathed so much that would lift the dipstick out of the tractor when running, about 10 years ago I made the mistake of wiring it closed resulting in an oil soaked clutch. After replacing the clutch I have a 1" piece of tubing running from a temporary cap thru the chassis and point...
