1960 David Brown 880 3-cylinder engine

Post by Ray Waldron » Mon Sep 30, 2019 4:39 pm

Can anyone help me? I am a 75 year old new member and new to tractor renovation. I have rescued the above tractor from a field where it has been stationary for 15 years. After many hours work I have got to the stage where the engine turns over but will not start. The oil filler cap blows off when cranking over so I think pressure is getting past the pistons to the crank case so I want to remove the cylinder head to find out why. Are there any manuals etc. on removing the cylinder head or can anyone guide me on the pitfalls of this job?

Manuals are available from various outlets. Try davidbrownparts.com
It would be very helpful if you could supply the tractor engine and serial numbers. This would enable identification of the type of engine in your early model.

After 15 years no go it is possible the excess crankcase pressure is due to seized piston rings in piston ring grooves.Before removing the head I would suggest removing the injectors and injecting 8 squirts of clean engine oil into each cylinder with an oil can.Replace the injectors and crank the engine on the starter only. The injected oil may then restore some cylinder compression. Then set stop control to engine run .This may,repeat may start your engine without the need to remove the head.If not ,then head removal is the next logical step.Hope this helps, AJK.
