[tank driver]

Hi All i am having problems with my diesel pump since the big freeze

got diesel going to the pump but the rail is not opening up to allow flow

the drive pedal is not doing anything all though everything is free i can

start her up if i manually push the rail across from the inside at the right

hand side of the pump does anyone have any ideas or any pump diagrams

that may help it would be very much appreaciated

Not being an expert on the 432, but living in an artic climate, what you are describing is a common occurence every year in the transition from Autumn to Winter.

 

Your fuel system has water in it somewhere and has frozen.

 

Over here we have diesel fuel system "fix in a bottle" thawing liquids.

 

Poor housekeeping has caused your problem, low fuel tank levels through the year promote condensation, lack of pre winter fuel treatment has failed to rectify any existing problems you have.

 

Sorry to bear bad news. If you can drag / shunt it indoors it will be easier to resolve, if not see what any heavy duty truck repair shop has for "fix in a bottle" material.

 

Alternate is tarp + heat vehicle, not a fun gig.

Hi Robin

 

thank you for your reply we have had it covered and has a gas blow

heater in the back for a day so it is all defrosted i can start it and run

the engine fine but have to do it by manually pushing the rail in from the

back of the pump i am sure you are correct and it had frozen up but i am

now at a loss as to why it wont start normally and tick over

 

kind regards

Check the fuel system carefully, do a filter job and add lots of new clean fuel. It is a fuel supply issue somewhere, crud is the cause somewhere, that is my suspicion.

 

I doubt you have sufficient heat to the engine bay to thoroughly thaw everything or get the heat under the floor to all the lines.

 

Can't develop any theories further as I dont know the machine enough to diagnose it remotely.

Hi Robin,

 

Thanks for all your help but after a phone call with Baz we are going to strip the front of the governer down.

 

Fingers crossed :nut:

I'm confused about "the pedal doesn't do anything" bit. Are you saying the pedal isn't moving the governor linkage, or it's moving but it isn't doing anything? You might also like to check that the emergency stop cable isn't stuck?

Carl,

 

Is it the fuel shut off soleniod (in the red circle) which you are having to push in to start the engine?

Has your pump starter/cut off solenoid failed, or have you taken it off...ah you just beat me to it...

That must be the first time I've seen one with the cover on! :cool2:
