Schlegel Farms, Hagerstown Indiana | My 1460 has an occasional miss and has just totally lost power a couple times (just like you turned the key off and right back on).
The first time it did this I thought I'd slugged it, got out and looked everything over and found nothing....started it back up and everything was fine.
After this I ran a whole day with no problem. Later the next day I noticed that it didn't sound quite right (had a miss at times), then it lost power a couple times but came right back.
Finally, it died when I pulled out of the ends of the row...... at first, it cranked but would not fire, I waited maybe 30 seconds and it started right back up so I took it back to the shop.
So far: changed all fuel filters and checked tank vent with no change, checked the fuel supply from the hand pump (it was good) (runs ok, but halfway back to field I hear the miss again).
I've been on the phone with my service guy and he keeps talking about a lift pump. He sent me some pictures (which I also found online) of a lift pump on the rear left right above the water separator filter.....my machine does not have one.
This combine is one of the very last 1460's built, when I went to the parts book, mine looks exactly like the early 1660 fuel set up (this is not the first 1660 parts we found on this machine).
Anyway, is there a lift pump somewhere on an early 1660, if so where? If not, does the injection pump just suck fuel up from the tank?
My serviceman is going to be here in the morning, just wondering what I may be looking at.
Ideas?

Center of the Universe, Huron County, Ontario. Can | Hi Mark
I had the EXACT same thing!!
My 1460 is late model but no red cab.
No lift pump either.
It turned out to be wheat that was sucked in the vent line on fuel tank.
It would STOP fuel supply completely at the little needle valve above your fuel filter on rear lower left of combine.
Exactly the same.
I thought engine or pump was pooched.
Drained fuel out of tank a couple times.
Caught more wheat grains.
It never happened again.
Hope yours is the same.
So diss assemble line that goes INTO fuel shut of FROM TANK.
let it drain.
I actually put rag around fuel filler and used air compressor to blow it out.
Best of luck.
I now have a small lawn - garden fuel filter on vent line.

NC IA | Some bean counter decided it would be a good idea to delete the electric lift pump for a few years. Very stupid idea. If any question of fuel supply, add in the electric lift pump (I even think its already wired for it.)
And as said above, check fuel tank vent. And of course all three fuel filters. |

There is a wire right back there that is hot when the key is on that is not hooked to anything.
I spent a lot of time today trying to figure out what that was for.

Somerville, Indiana | oughta be a federal law to have an electric fuel pump in line of every machine.
Edit: the hot when key is on is for the fuel pump...We had an old 1460 that had electric fuel pump at a water separator left of the fuel tank...Same deal-but different looks on a 1688 many years later.
Be sure the breather line is clear
If the fuel tank is full, there isn't much more than 2 feet? to draw from the engine fuel pump, bean counters thought that wasn't anything to warrant an electric pump...Nice job sitting in an office out of the dust, hot, and cold...Wouldn't trade places for anything though.

When it loses power , stop and remove the fuel cap. If air rushes into the tank with a woosh, the vent tube on the filler is clogged. It was enough of a problem with our 1480's that we had a bit of electric fence wire attached by the filler neck to rod out the clogged vent tube . Also might be dirt in the tank clogging the in tank screen. Remove that bottom tank fitting to remove the screen. shut the combine off and the dirt settles off the screen, run it for 30 minutes and it clogs again. May need to totally drain the tank to get it clean. |

Centralia, MO | I had a similar experience but mine turned out to be the fuel shut off solenoid on the injection pump. The plastic broke down on the end of the solenoid and stopped making a good connection. It would die dead as a hammer. |

| I dealt with this issue on my 1460 on tuesday. Turned out it was the screen in the bottom of the fuel tank like the poster above mentioned. There was a ton of black gunk on the filter. Haven't had any problems since I cleaned the screen.
Let us know what you come up with on your machine. |

| Did you take the fuel line apart between the water separator and the fuel tank?
Did you have lots of flow?
Your symptoms sound nearly identical to what our 1640 was doing when we had algae in our fuel. It was black slimy crap that was plugging everything up including the screen in the tank and all of the filters.
If you cut the water separator apart and its full of black slimy crap that is what you have and you'll have to use a chemical treatment to kill it and get rid of it.

| What chemical did you get to put into your tank to kill the algae? |

I think this is the product that we used. We got it from our fuel supplier.

New York, east end of Lake Ontario | Had same problem with my 1460 a couple years ago, was some crap on screen at bottom of fuel tank. Would float off but when it called for more fuel it would suck down to screen and kill it. Suction stopped would start right up and run fine until it got in right spot to plug screen again. Took apart and took screen out and got some crap out, problem solved. Good luck, I feel your frustration |

Cen IL | i took the brass screen out of the bottom of my 1460 fuel tank and threaded in a sediment bowl for a IH M. Should have been put there from factory. Mark, I got a Mr. Gasket electric fuel pump at Oreilly auto parts to replace the lift pump on mine. Fit up was perfect. Don't figure on getting over 750 hours out of it however. |

Adrian,MO | Check the valve just ahead of the water separator, we had a early 1660 it was almost plugged with bean fuzz |

west central Iowa | My 1660 with the lift pump would run out of fuel and die and I would have to bleed it to get going again. I took the line loose by the lift pump and blew air back up into the tank. It's been going at least four years since I did that, but it will probably quit tomorrow now that I talked about it. |

| Have done this also.. take fuel line apart by shutoff valve by filter an look in valve an blow some air thru make sure cap is off tho.. we had a corn kernal... In1688 |
