David Brown Tractor Forum

I have a 1965 Implematic I bought about 20 years ago, Have rebuilt the power steering, built a ROPS, repaired almost all the tin work and most recently welded the rear rims and fitted new tires. I just recently added a Stanley Muffler, made in the USA it weighs 5 lb, I would be interested to hear ho...

Thanks for that, it makes sense. I will check the breather bolts again, its been awhile. So I should expect to see some grease coming out around the axle when the cavity is filled up? I am thinking when it warms up I will add a little more grease every hour of use until I see some oozing out. That i...

Thanks for the reply, I was wondering about that, I put a couple of shots grease in there and did not see any ooze out so I figured it must be going inward. This seal has always leaked a little oil and the grease seemed to fix it, a lot easier fix than pulling the thing apart. Its been like 20 C bel...

After owning a implimatic 990 for close to 20 years I found another grease fitting, turns out you have to drive forward until one of the holes in the right rear wheel hub is at about 7:00 position, thru that hole there is a grease fitting on the final reduction. Similar on other side. From looking t...

Some more details on the tractor, Following are some more details, Tractor is a 1965 David Brown 990 Implematic, serial number 478280, Attached below is 2 figures from the IT service manual showing the parts needed. From the auto hold figure 160, I need the right side rock shaft support housing #4 a...

I have a 1965 990 implematic with busted rockshaft supports, anyone know of used parts? Lacking that, any advise on welding cast iron? Any chance selectomatic parts would fit? I realize I would not have full function of the 3PH but think it would still raise and lower and work the bucket. I hate to ...

So is the selectomatic PTO housing different from the Implematic PTO housing? I am not too concerned with the load sensing feature, The tractor did not come with a load sensing top link anyway.

On my 1965 990 Implematic the top link of the 3 point hitch attaches to the rockshaft under the seat. When lifting some attachments the top link hits the seat. raising it. Also, I want to mount a logging winch and am concerned about the strength because there is a crack in the right side rock shaft ...

I mounted a standard hydraulic cartridge filter on the return line from the loader to the transmission, has been working good for years. Fluid pressure at the inlet to the filter is 15 psi.

Anybody know what the grill should look like on a 1965 DB 990? Mine is a implematic with white paint and Case on hood, misisng the grill. I want to build a new grill (radiator shield) and would like to have it look something like the origional. Thanks

I have a early 1965 DB 990 Implematic with 3 screw type remote valves on the operators left side. Closing the center and opening the right valve forces fluid to the front end loader (if the 3 pt lift lever is raised up). Fluid from the loader returns into the fluid fill port on the front of the tran...
