5 ton multifuel engine cuts out

[Bchantler]

Hi Guys,

I'm in the UK and have a problem with my 5 ton dump truck, the multifuel engine will start on the button after being stood for months, I then take it for a run, after 10-15 miles if I drive around a roundabout (clockwise) the engine cuts, just like someones turned off a switch, once its done that a few times the same fault can happen on a straight road, might drive another 5 miles or cut out every 50 yards.

The turbo whistle goes silent, sometimes it will bump start before stopping if I'm in a low gear, if not it rolls to a stop, I crank the engine for 5-10 secs and it fires up like nothings happened, no hesitataion, all 6 cylinders fire at once.

Fuel tank is full, I've wired the fuel pump direct, changed the fuel filters and checked the tank is vented. The stop lever is fully in and doesn't seem to move whislt in motion.

I have noticed lately that it's not so smooth on tickover, if anyones in the UK the truck is down at the War & Peace Show, pop in for a cup of tea and slice of cake.

Could there be water in the fuel tank?

You may want to pull the in tank pump and check the inlet screens. Recently had one that was 90%+ blocked with spooge.

You may want to look for an air leak along the fuel lines. Bleed the lines/filters using the "bleeder screw" on top of the secondary/final filter bracket to check for this.
Another possibility is the fuel cut-off lever, that may be sticking. It has no solid mechanical connection to the fuel cut-off lever, it just pushes it to the stop (fuel off) position.

All are possible solutions but I think you got something in the tank that is getting sucked up on the lift pump screen. I would pull it over to the FSB and pull the tank pump and take a peek inside!!!!

Have a good time on the farm, tell Stuart and the boys that Jeff in VT says HI!!!!

Max Levell still party with you guys anymore???

One of these days Ive got to get over there.
