CAT 259D

[Nour Vachon]

Im working (service) on this unit and am having issues with power (none) at my 2 pin connector for electric fuel pump and fuel pump is toast. Gave the pump 12V and nothing. Fuses are fine. Changed screen filter to pump and secondary filter (clear plastic container). Secondary wasn't full when unit came in and was starting/running fine. I've read these units can still run if the electric pump isn't working since the system is under suction. Can anyone help me with what relay I can check to see why I dont have 12v to my pump? It cranks but can't get pump to prime.

I've sent you a copy of the schematic. Check your messages.

On my 248B, the priming pump is activated by leaving the seat bar up, turning to CRANK momentarily, then leaving the key in RUN. Ironically, this is not what's in the operator's manual.

Similar issue with my 259d currently, any chance I could get a copy of the wiring? FTL01098

I'm having a similar issue. Any chance I can get a copy of the wiring?

Certainly, if you supply a Serial Number.

Unfortunately I can't. All the plates have been removed bought at auction, listed as 2017 by the engine.
Thanks for the reply.

Got an engine serial number?

8HG5584
MODEL C3.3B

Did you check the location where the plate is supposed to be.? The machine Serial Number should be stamped on the machine frame right underneath where the plate was. If that number has been ground off, IMHO somebody had something to hide. Just because a machine has been through an auction is no reason to remove the S/No plates.

8HG prefix comes up as a generator, and by that I mean the electrical part not the engine. Got a photo of the plate.?

 

[river's roost]

I've looked there and didn't see anything stamped or that there was any grinding done.

 

[Nige]

What about a photo of the engine S/N plate.?

 

[river's roost]

This is the plate.

 

[Nige]

This is the plate.

Gotcha........!!
Machine S/N is FTL13164. Built 10th July 2017.
I'll send you the correct electrical schematic. Keep an eye on your messages.

 

[river's roost]

Thank you sir!

 

[Nige]

If you really wanted to you could visit your local Cat dealer and order a replacement (duplicate) Serial Number plate. There will be paperwork to go through but I'm reasonably sure it could be done.

 

[Cmark]

How did you get to there Nige?

How did you get to there Nige?

Yes sir. Do tell. I can't seem to work backwards from that particular engine serial number either.
