Well Isabel's still in a state of woe

as I had to work on the digger
rebuilt the engine isuzu 3kc1 3 cylinder diesel. Then all day Sunday putting it in. Still not finished but 3 hours spent trying to get the beeper started.
still not happening so going to look at diesel timing not nice on a Bosch style injector pump but shouldn't take long
famous last words. Plenty of fuel and now compression and black smoke from the exhaust. So fuel is black usually Indicates too advanced timing white is retarded. but I am hoping not other wise it's engine out and strip of the front cover again. Agggr.
Any one a diesel pump repairer. Cos if I can't get the timing right or it is right then it's pump repair time ouch.

It's a beeper to set and very messy plus you have to order shims to put under the pump body.
I am a bit scared of finding a horrible thing ie duff pump cos I am def out of cash and it's going to hurt.

If the digger was a horse I would have shot it by now.

Black smoke also indicates overfuelling

Hi it also can be very advanced timing on the pump it's currently about 26 deg advanced which should be 12 deg advance I have lifted the pump effectively retarding the ignition and managed white smoke (incomplete burn) but still no go I have pump being looked at they say worn out . I say yes right . Will be collecting it back unfixed sat am. I am going to look for the pump veins and delivery nozzles on the net then get it set up but I will be checking out the possibility of hydraulic. System over loading the engine so full rack open over fuelling by 50 present for start as it fires during turning over the load ie hydraulics load up then as the engine fires the govner kicks in and reduces fuel by 50 present for idle but engine loaded up over and above the slow speed amount of fuel. Causing black smoke as in over fuel as you suggest.

Thanks for the suggestion you know what it's like eventually you doubt yourself.

Off to get the pump in a bit so when I get back it's an hour each way. I will probably have to re assemble it then I want to try and rule out the hydraulics over loading the starting of the engine or at least force the pump to go max fuel. If it doesn't work I have the rest of the day and a bit of tomorrow morning with Isabel. Mabel an mot will be looming yippee

Hi ya all got the old nag sore of running ye ha ridem cowboy but alas not properly. It was a case of messing with the pump timing to get her to fire and then just keep it running by over coming the govner with finger power to overcome the govner. I also wound in the rack stop idle until there was enough fuel to run a fighter jet. Everything fitted back to normal and set to correct settings with exception to the fuel pump. The timing is about 15-20 degs advanced because to retard the timing you add shims 0.1 mm is equal to I deg the problem is the pumps so worn that it stops pumping enough to over come the new injector springs in the injectors.
The pump is now out again and I an looking for pump parts on the net . I can then rebuild it but will have to pay for its set up.

Any one got a set of pump elements and delivery valves for a diesel Kiki 43011 pump. They were bought out by zexel pumps who were bought out by bosh but luckily the bits are available.
