RE: DB770 Gold Louvre Plate

The very early White/Brown 770 tractors to which I refer in my original question are the tractors from Ser No. 582001 (first white/brown model manufactured Oct 1965), to Ser No. 583183 (manufactured Feb/March 1966 – assuming tractors were produced at a consistant rate throughout the year). These t...

DB770 Gold Louvre Plate

On the front cover of Anthony Heath’s book “David Brown Tractors 1965 – 1988â€￾ is a farmyard scene showing the 770, 880 & 990 Selectamatic models. Text inside explains this is a photograph taken in the summer of 1965 prior to the public launch of the new white & chocolate brown colour scheme. I note that all three models are fitted with gold louvre plates in the upper part of the bonnet, however I have seen several 770 models from late 1965 which do not have & have never had the gold louvre plate. Is anyone able to explain?

RE: 2WD axle sizes.

If the stub axles vary in angle of camber as Powerrabbit suggests, why is the part number of the stub axle the same for all 2 WD models from 1200 to 1690/1594, ie K962019?

RE: 1290 piston size......

John. The sizes on the attached link are scanned from a DB brochure & are correct for early 1290 models. The 101.6mm (4") dimension is the stroke, not the bore.

Please be aware that later 1290 tractors were fitted with a de-rated 1390 engine of 3594cc, 3.94" (100mm) bore x 4.5" (114.3mm) stroke.

RE: Carbon Thrust Bearing

Question for JamesF. Do you know a source for the replacement carbon thrust bearing to fit a DB 850 with single clutch? I have seen the early type as fitted cropmaster/25/30 series tractors advertised but not seen the type as fitted to the Implematics? These were a heavy cast tube with a recess mach...

RE: Early vs late 995

The 990, 995, 996 Synchromesh range of tractors was introduced by David Brown in 1971 to replace the 990 Selectamatic model.

The 990 & 995 had the traditional two stage “livedriveâ€￾ clutch similar to that fitted to the old 990 Selectamatic tractor.

The 996 had an independent clutch with the PTO section operated independently by a hand lever, similar to that fitted to the 1200, 1210 (at that time) & 1212 models.
However as the independent clutch is thicker there was insufficient space within the original 990 chassis to accommodate it. To overcome this a 80 mm thick spacer was installed on the 996 between the front & rear main frames. This resulted in the 996 initially having a longer wheelbase than the 990 & 995 models.

In early 1976 the wheelbase of the 990 & 995 was increased to that of the 996. At the same time a new single piece longer front main frame was introduced to replace the former short front main frame & 80 mm spacer.

In the late 1970’s the independent clutch was also fitted as standard to the 990 4WD model & became an option on the 990 2WD tractor.

In recent years I have seen reference in the tractor magazines to a 995 4WD. I would be interested to know if anyone has any knowledge of this model, as I can find no mention of it in any UK brochures or sales literature. If a 995 4WD had been manufactured I assume it would have also had the independent clutch like its siblings which would have made it the same specification as a 996 4WD.

The above applies to UK specification tractors. I realise in the North American market the model designations are slightly different.

So far as I am aware the "older style" water pump pictured above was never produced with a threaded hole for the connection of a heater hose. This was because this type of pump was fitted up to approx. 1974 while heaters were not introduced until approx. 1976 with the introduction of the quiet cab.

RE: DB 1210 4WD is this a Kramer front axle?

As other contributors have identified the axle pictured on the DB 1210 tractor is a Kramer axle. So far as I am aware the David Brown axle was never fitted to the 1210 & 1410 tractors for the UK market. The DB axle was used on the 990 & 996 models for the UK market & then carried over to the 1290, 1...

RE: 1690 crank price

I checked with Case IH yesterday & the crankshaft has been no longer available from them worldwide since 2009. I suppose it is possible that an independent Case IH dealership in the USA still has stock, but I feel it is unlikely. It would be nice to know?

Are 6 cylinder crankshafts, part number K914788 still available in the USA?

As far as I am aware they are no longer available from Case IH in Europe, & have not been available for several years.

RE: hydraulic filter pressure switch DB780

The part you require is K921214 Switch adaptor which is still available from any Case IH dealer, although they may need to order. The usual cause of breakage is when the PTO unit is removed without first removing the switch adaptor, which is hidden out of sight under the PTO unit.

RE: Locating plate in oil filter

I have not heard of Powerrabbit's explanation before. I always assumed it was there to keep the filter element horizontal & parallel to the bolt, while the bolt is screwed into the cylinder block. If not fitted the inner end of the filter tends to hang down & probably would not seal correctly agains...
