560 Diesel won't start

nisse · Aug 29, 2012

I am helping a friend try to get his 560 diesel going. It ran fine last fall, but has always started hard. Here is what we have tried, replaced the fuel filter(it is an aftermarket filter)cleaned sediment bowl,drained the fuel and filled with new, checked for power at the glow plugs which they all had. We have had the block heater warming it for about an hour before trying it and had the glow plugs going for over a minute. There is smoke almost immediately and it almost catches right away but after that it just cranks with no sign of life. Any ideas what to check next?
Thanks,
John

Twice on my 560D I have the rubber fuel line collaspe between the final fuel filter and the fuel pump. Replaced that line and engine started and ran good. Hose looked good on outside. When you are bleeding fuel filters it is not enough to have fuel seep out! Open filter bleeders and hose connections and let fuel FLOW for at least a minute or 2! Keep us updated as to what does on does not work. Armand

It catch's immediately and then never tries again. I will ask you, are you continuing to hold the glow plugs while you are trying to start it. You must on a hard starter. That first couple shots of fuel will cool them glow plugs off and then you are done. Of course poor cranking speed will lower the voltage so glow plugs are not effective. I would resort to a pull, fifth gear, ta ahead, fuel shut off pulled out so no fuel is injected until it has cleaned it self out and warmed cylinders, glow plugs held on, then fuel shut off pushed in , full throttle and fire it up.

I know it may be stupid on my part to ask, but did you bleed the injectors? Bleeding the injectors is a necessry step on those old Disels.

I did crack the lines at the injectors and got fuel, yes we are keeping the glow plugs going as long as it cranks, and it doesn"t have a fast hitch. We also took off the return line and it flows good from the tank, saw on here that was a common problem. Thanks for all the responses.

Take a 15/16 boxend wrench and give the top of the inj. pump a couple of sharp raps.

oops never mind i read all the threads and you are getting fuel.

After reading your post, I think that your glow plugs are not working. You said that you checked for power to the glow plugs. Did you check if the plugs are heating? The service manual tells how to use the glow plug meter on the dash to check each plug. You can also use an ohm meter and check each plug with wires disconnected. Some people just remove the plugs and check to see if they get hot when electric power is applied. Let us know what you find. charlie

Have enough battery and large enough cables and a decent enough starter to spin her fast enough? I run 2 1000cca batteries in parallel with 2/0 cable and it was a world of difference in starting compared to a single and #1 cable... especially on my worn out old 282

Hey!!! I just started my 560D for the first time in 4 years. I have been trying everything to get it to run. Finnaly pulled it about a half mile before it started. The trick is to pull the fuel shut off untill everything is wormed up and moving. Mine had lost prime and wont turn over fast enough to suck fuel through the filters. Pull it !!

A good flow of fuel from the tank on the return line only indicates that the return check valve is missing from the bottom of the tank and that the line is clear.

What you need to check is that you have a flow of fuel coming from the return fitting on the top of the pump while the engine is cranking. Your description of almost starting one time and then nothing is what you could expect if you had a plugged return fitting on the pump.

We did get the tractor to start today using a little ether, it ran very good after it was running. I am thinking it is probably the glow plugs. Tried to remove one today, is there a trick to removing them? Couldn't get it out, snd didn't want to break something by forcing it.
Thanks,
John

Hope you didn't use ether and glow plugs at same time. You can blow that manifold , air clearer and more right off that tractor. No trick to getting glow plugs out. They get carboned in from not sealing properly on the bottom end. The threads do not seal the glow plugs. They have a tapered seat at the bottom so bore must be clean when installing them. Anti-sieze on them help. Don't get too rough with them because if you twist them off they are hell to get out if you can get them out. If you check each glow plug individually, by unhooking all but one, meter should read about half on gauge. I like to get at least one out, ground it and with all glow plugs hooked up normally it should get red hot in about 20 seconds. This will prove you have good enough electrical connections through system to make them light up, but all have to be working for this to be a good test.
