Starting procedure for 3005/790

[Fred Deere]

The online manual for cold starting reads as other have described for your tractor. Here's a link to it. Seems your printed manual is different for some reason...

Your key switch looks like this, right?

...............................................

Yes just like that, and infact the directions on the tractor itself do not have the extra line"hold in key for glow plugs etc" but only in manual.

I just wanted to make sure I did not do any harm by missing a step.

Thanks to all for responding.

I emailed my dealer, I will report back, but obviously you guys know, so it is a mistake I am sure.

Position A - Preheat/Cold Start - Rotate the key to this position to allow the engine to preheat. The engine should not run.

Position B - Off - With the key in this position, all switched power is off, and the engine should not run.

Position C - Run - Rotate the key to this position and the engine oil pressure light and battery charging lights should illuminate. You will also hear a clicking noise when the engine fuel shut-off solenoid engages. Hold key in until engine runs smoothly to keep glow plugs activated on initial startup.

Position D - Start - Rotate the key to this position to allow the starter to engage the engine flywheel and start the engine. When the key is released, it will automatically return to the run position, and the engine will continue to run.

..................................................................I followed the link provided and it still shows under position 3 the exact language from my manual..last line in C..HOLD KEY IN UNTIL ENGINE RUNS SMOOTHLY??

Well, that is the strangest thing. Should be interesting to hear what the dealer has to say about it. In any event, I wouldn't worry.

 

[Fred Deere]

Not to bore you guys, BUT

Looking in my manual under engine specs, under starting aid....says GLOW PLUGS...

I have not heard back from dealer, they are probably still laughing...the guy thinks he has glow plugs

 

[RobS]

Well hey, maybe it does have glow plugs. Maybe your ignition switch does have a "push" position. Do you have a service manual or parts book to reference? I know for sure that my 790 does not have glow plugs, but I can't say for sure what the manual says. I'll check tonight.

Y'know, it's interesting too that in your description of switch position A, it mentions engine pre-heat. I seem to remember my manual being pretty specific about intake air pre-heat. Hmmm...

Indeed the 3005 may have glow plugs. The 3005 on-line parts catalog also shows glow plugs.

Fred, maybe you could look at pictorial display in the on-line parts catalog for the 790 and under the alphabetic index for heater to get an idea of how it looks, and then the 3005 glow plug pictorial. Then look at your 3005 engine and see if it has a rectangular box with an electrical connection above the intake manifold (air heater) or an electrical connection on the head near where the intake manifold is (glow plugs).

Here is a picture from my maintenance manual of the heater.

Here are some pictures of what the air heater looks like on the 790. The air heater is just below the rubber air intake hose. It has an electrical connection on it and also the coolant overflow tank is bolted to it.

I HEARD BACK FROM DEALER, maybe you guys can decipher what he said here it is....

Good Afternoon
Thank you for your note. I am glad that you now have room to park all your
vehicles. About the tractor. Your tractor should have glow plugs. it is a
manifold heater. In the new 3005 tractors (not the 790's) you turn the key
to the on position and leave it for 5 to ten seconds. The tractor should
start. On the old tractors you had to push the key "in" which means towards
the steering volume. If yours can be pushed in, then you have an ignition
from the older series, which Deere would do in the transition to the new
series. Both will work effective.
Where the confusion may be with your chat room, is the old style of glow
plug was actually in the engine and it warmed the block up. Not so with the
manifold heater, they warm the air before it is fired.
If you have any other questions or concerns please contact me.

You might want to talk to a mechanic at your dealer. Glow plugs and a manifold heater are two different things. My 790 has an intake manifold heater. On my 790 you turn the key counter clockwise to activate the heater. If attached a picture that elalexander took of a 3005, thread "3005 replacing the 790" and it looks like it has an intake manifold heater just like my 790.
