Re: DB1210 surging RPM

The 1210 Operators Manual tells that the injection pump oil shall be changed every 125 hours of operation. In your case a I suspect that there is a mixture of water and dirty/old oil in the pump governor housing. This will lead to rusting of some of the pump parts. Try to open the bottom plug on the...

Re: DB1210 surging RPM

So you got the pump from the diesel shop without oil in the pump and then you fitted the pump to the tractor without filling the pump with oil to the correct level. If this is the case, then you can have some seriuous problems with the pump after it has been run dry.

Re: DB1210 surging RPM

Have you changed the oil in the injection pump? The rack in the pump can stick if there is no or dirty oil in the pump.

Re: piston rings and bearing shells

The Operators Manual for the tractor asks for increasing the engine revs to 1000 r/min after the engine has started and then check to see if the engine oil pressure light has gone off. The low idle speed for the engine is 700 r/min (and must be no less) and it will take longer for the oil pressure t...

It is in fact the opposite, mineral oil is the oil to use in older tractors, and not synthetic oil. The use of a mineral oil with aa higher viscosity is recommended because the pumps used in the olde...

Re: Gearbox Oil

The varm up "not required with the synthetic oil", is because most syntetic oils have a larger viscosity index than a mineral oil. A mineral oil is usually at the most SAE10W-30, but a synthetic oil can easely be SAE 5W-40 or 0W-30.

Re: Gearbox Oil

We use SAE 80W/90 GL-4, mineral oil in the older DB tractor transmissions (not in Selectamatic tractors) around the year in Finland. SAE 80W gearbox oil has a viscosity near the same as a SAE 15W/20 engine oil when the temperature is below zero degrees centigrade. A hot SAE 90 gear box oil has a vis...

The numbers in the pictures are casting numbers for the parts the numbers are on. The tractor model and serial number can be found stamped on top of the front bolster (engine frame) on the right hand side, just behind the bonnet skirt and just to the rear of the radiator. The picture of the gear lev...
