Re: 880 hydraulic problem

Thank you for your reply. Good you got it working. A loose latching valve sleeve is not a very common fault and finding this require some in depth knowledge.

Re: DB Brakes

There is a possibility that you can free the pto clutch disc if it is stuck to the flywheel or the pressure plate. Connect a large pto driven implement to the tractor, a rotavator is a good example. Put the pto in gear, start the tractor and lift the implement out of the ground. Now push the pto clu...

Re: DB Brakes

You will need a hoist or a trolley jack for removing the final drive. The unite is very heavy. And the pto problem. You wrote "disengage when I push back the hand lever because I cannot engage PTO lever". What do you mean, is the pto selector lever stuck or will moving the lever result in a gear cla...

Re: DB 880 Selectamatic

You can not just fit a "modern" temperature gauge. The resistance (ohms) in the gauge has to work together with the temperature related resistance in the sender. The 880 Selectmatic tractor newer had a temp gauge with a background light and this tells me that the gauge you have might not work togeth...

Re: 90 series power steering problem

Disconnect the hoses at the steering cylinder end and turn the steering wheel slowly left and right several turns and times. Push and pull on the steering cylinder piston rod. Do not start the engine in doing this. Do not fill the system with new oil before you have changed the filter.

Re: 90 series power steering problem

I sdo not think that the original oil in the steering was ATF, but a engine oil or a hydraulic oil. Mixing ATF with other oils will make the oil foam.

Re: Leaking steering column DB 1210

The oil is coming from the Orbitrol steering valve. The shaft seal in the Orbitrol is leaking.

Re: 90 series power steering problem

The pump shaft axle seal can be faulty in two ways. Engine oil will get into the steering when the engine is running or oil from the steering will leak into the engine when the engine is switched off. What oil was used in the steering system when you got the tractor and what oil have you used for to...

Re: Cylinder head nuts

Well, the manufacturer found out that standard nut wouldn't do the job, so they fitted specially made one for the purpose. This is all that you have to know. If Cobbadog want to fit standard nuts, he has the right do so, but there is most likely problems around the corner in doing so.

Re: 94' series 4wd components the same?

People in US are calling the transmission power shift but the correct name for this transmission is hydrashift. Four gears without the use of the clutch in 3 forward and 1 reverse range. The 1964 was only available with hydrashift transmission.

Re: 94' series 4wd components the same?

Well, who wrote this then: "Will, say a 1494 nose and axle fit the 1594 frame/ engine housing"? And one more thing, the engine in a Maxxum (51-series tractor) is not really a Cummins, but a engine based on the Cummins engine and called CDC (Consolidated Diesel Company).

Changing the 1594 6-cylinder engine to a 1494 4-cylindrer engine will completely destroy the usability and value of the tractor.

I was almost sure that you would understand the setup by looking at the line drawing I sent in the link. The 3 pipes are going trough drillings in the rear axle and the pipes are kept in place by the locating plate and the plate is fastened to the rear axle with some screws. The location plate slide...
