No power

[Luke Fitzpatrick]

Hi all. 

I have a case international 885xl 1990 model. The engine has recently been rebuilt and for whatever reason it struggles to start but will turn over after about half a miniute or so then it losses power straight away and will not respond to the throttle or reach the rated rpm. When turning over it produces a lot of white smoke which does clear. I have drained the fuel tank and cleaned the banjo bolts, replaced all the fuel pipe all the way to the primer pump. Replaced the fuel filters, bleed the system, the injector pump has been reconditioned and all the injectors have had new nozzles. I removed the air filters and will replace them as soon as. However I tried starting it without the air filters and the problem still persists. The only other symptom is at idle it produces a light grey/white smoke and smells of unburnt fuel. The oil is as should be and not milky in anyway and the coolant level doesn't drop at all. 

All help and advice greatly appreciated 

Regards 

Luke

Is everything timed properly? Did you do the overhaul?

[Luke Fitzpatrick]

Thanks for the reply. I have thought about the timing and that was my next step as I’m baffled what else it could be. A friend of mine has done the overhaul and I have helped out on the majority.

Another thing to check is to make sure there is no air intrusion into the fuel system. Make sure air is bled from injection pump and lines and if any part of the system is under suction ie from from fuel tank to injector pump.

What injection pump do you have a Bosch "BR" or "CR"........the over flow valve of the "BR" pumps are in the banjo bolt top center of injection pump, while the "CR" pump overflow valve is built into pump and banjo bolt is the same as one on supply at front on pump. Many times I have seen these get mixed up on "BR" pumps and with wrong banjo bolt on supply side it will majorly restrict your inlet flow.

Interesting I can’t rember if it is a BR or CR I will check and let you know the outcome. Thanks for the help.

Will do. I’ve replaced the fuel line from the tank to the primer. I even bypassed the whole lot to see if that was the problem and put the fuel line straight into the fuel tank via the filler cap. Still the same problem. I read somewhere about leaky fuel primer I.e taking air in.
