Replies: 5

While olleks explanation of the engine designation is correct for the 4600 model, the 3800 is different. My understanding is that the 3800 engine is a gasoline version of the white 770 diesel engine (ie 3/49 100 mm bore x 4 inches stroke) so a capacity of 3.4 litres (147 cubic inches) is approximate...

If you go to a Case IH dealer & specify you want a genuine Case IH K68073 & not a equivalent, then it will be correct. I realise a Case IH dealer may be some distance away.

I note from the log book it is only 2200 cc capacity which is smaller than any other David Brown 4 cylinder engine. However i believe the 750 model tractor for the German market had a similar sized engine, so there may be a connection there?

RE: 770 - Linkage levelling components

Unfortunately K913845 Levelling lever assy, K913170 Bevel pinion & K913224 Levelling screw are no longer available from Case IH & as case-ih1594 suggests used linkage parts in good condition are difficult to find.

770 Hydraulic bypass filter

I was watching a film on Facebook last night which i think was posted by Jim Cochrane. It was explaining the features & operation of the Selectamatic hydraulic system on the then recently introduced DB 770 (red) tractor. The tractor featured had what looked like a conventional hydraulic bypass filte...

RE: Re: RE: 780

The 780, 880 Selectamatic & 885 engines are mechanically the same & all share the same fuel injection pump. I remember when the 885 was introduced we were told the engine power outputs were all the same, but were measured to different standards. Something to do with the 780 & 880 being 46 BHP & the ...

RE: Re: RE: Hydraulic Filters

I always believed that all early selectamatic models had the hydraulic bypass filter on top of the axle, however i am willing to be corrected. What does interest me is what do the early tractors without bypass filters have in this position? Do they have the machined flat surface on top of the axle w...

RE: DB1212 Front Axle Extension

I am interested by Ollek's comments regarding the K prefix. I was on a parts coarse at Meltham Hall in February 1976 & the subject was talked about. The explanation we were given was that with the take over by Tennaco, & the introduction of a Case USA model (970 Agri King) to the European market, th...

RE: DB1212 Front Axle Extension

L/H & R/H front axle beam extensions are normally different as the "lock stops" are welded on in slightly different positions, hence the different part numbers. In my experience the part numbers are often stamped on them with a metal stamp but are not easy to see & often overlooked. The K prefix may...

RE: DB 990/996

I cannot see a major problem fitting a DB 995/6 AD4/55 engine into a DB990 implematic tractor. As Powerrabbit suggests you would need to fit your existing flywheel & clutch. It should be remembered that when the supply of replacement AD4/47 cylinder blocks was exhausted, DB parts dept would supply A...
