Title: 2.5TD FAULT CODE
Post by: Seth on 03 April 2008, 23:28:02
Hi all,
Have just had my tractor diagnosed with fault-code 64.
Overall, it's performance is pretty good, but revs seem slow to pick up, particularly after a gear-change.
Then, when the power does kick in, away we damn well go!
The garage, (in my presence, and good friends of mine) said the fault lies within the injection pump - crikey that's around a grand to sort!
I still reckon there could be a tank-pump problem, or even crud around the tank pick-up strainer - anyone got any ideas to help a fellow tractor-lover?
PS - other than this niggle, the BM lump is running well at 140k miles.

I don't think your tank pick up problems should affect the performance of the car once started - as mine has a dead tank pump too...

Would I be correct in saying that Code 64 is "Fuel Quantity Control Out of Range" ? If so then this could be a pump problem, but my knowledge of these is not a lot at best.

Does it always feel a bit flat after gear changes or just occasionally?

The best thing to do next is remove the fuel filter, empty it, refill with neat Diesel Magic, refit, then start the engine (may run like a sack of spuds for a few mins).  This helps to clean out the conatcts in the injection pump, which is the most likely cause of a 64.

Thanks fellas,
I've already done the business to the fuel filter - so we'll see how it goes.
Other than this, I'm reluctant to shell-out mega dosh on a 10 year-old tractor, so I'm thinking it's going to be a case of living with it. I've found that judicious gear-changing, (to keep the lump revving), definitely helps - so it'll also be a change of driving technique!
Incidentally, there was an intermittent rough idling problem a few thousand miles ago. I cured this by dismantling the complete fuel filter assembly, then reseated and retightened the pre-heat block to the filter case. Then added a new filter and filled with Forte. Next came new copper washers - result is perfect tick-over!
If anyone has further ideas, then please post them - thanks again.

The diesel magic normally improves situation.  If not, it is possible to remove top of pump, and iirc, the wiper is then visible.  Do any damage in there, though, and its bye-bye injection pump, so be mega careful if you go down that route.
