Hi. Brand new to the forum.
I have recently purchased a MF 35 Serial # SNMY 328509 which dates it 1963, dual clutch and diff lock with the Perkins 3cyl Diesel engine.
Engine has done 1660 hours, and i believe this to be accurate given the condition of the tractor.
I am having some trouble with it starting. While it will start and run fine, while cranking over from cold it produces a lot of white smoke and when it first fires a decent puff of black smoke comes out.
After cranking for around 20 secs it will start and run on 2 cylinders. Running at 1200 RPM for another 10-15 secs the third cylinder will kick in and the black smoke reduces to very little.
When it is running, at a constant idle little or no black smoke it noticeable. When revved a typical small puff of black smoke is seen (though not very thick) that then dissipates.
I obviously want to repair this. After extensive google forum searches and talking to various people, I'm after other opinions.
Further to this, the coolant appears fine and the level seems to stay the same. No bubbles are present so I feel the head gasket is ok.
Engine oil is down slightly but I haven't done enough hours to see if it is using any oil or whether the lower level is due to normal consumption. The exhaust is not oily, just the normal diesel black. Oil is not watery or discolored in any way. No blue smoke has ever been seen by me.
The only thing left that seems obvious is the injectors. I doubt very much they have ever been serviced, and the manual states every 500 hours (I think) for this.
What do people think? Should I look elsewhere? Compression test?
If the rings were gone the engine oil should give me some indication. I have not removed the dipstick while running to feel for pressure buildup in the block. Would this be an indicator anyway?
I am yet to do a full service including filters, so the fuel filter may be fairly blocked up, but this should only affect performance and generally starve then engine.
Feel free to address anything I have said.
