Starting procedure for 3005/790

[Fred Deere]

Hello

My new 3005 JD has me confused on starting procedure. It`s working fine, just that I do not understand the manual starting procedure on one point.

I understand pre heat etc, just that manual says "hold key in until engine runs smoothly, to keep glow plugs activated on initial startup"

I am holding key in but there does not seem to be a way to push it in? I push in there is no spring motion or anything?? Just trying to make sure I am not doing something wrong?

This is just in manual. On tractor itself it does not say, "hold in key"

Does the key actually push in and out, because I can`t feel anything happening when I push key in....

Maybe its just bad translation from Japanese language?? ANYBODY

I'm at work now, but from memory the glow plug activation is by turning the key to the icon next to the key. The key does not push in. One direction (clockwise) starts the tractor and the other is the glow plug (counterclockwise). It is like cars that have an accessory switch on the key start. Go look at all the little icons.

First off, the 3005/790 does not have glow plugs... just an air heater. My experience is that you don't need to bother with this unless it is down near freezing. What you do is turn the key counter-clockwise for about 20 seconds. This heats the air in the intake manifold. Then so the engine will get a big gulp of this warm air, you advance the throttle a lot. Then turn the key to the starting position and as soon as it catches bring the throttle back to about 1400 rpm.

Try starting the engine normally first though. If it starts don't bother with the cold start procedure.

On my 790, at 8600 ft. I use a block heater except for the warmest summer months. With it I never need the intake heater. If I don't have the block heater plugged in I have to use the intake heat most of the time, below about 70 deg or so, I assume because of the altitude and it smokes a good bit until it warms up.

Muxster is correct. The 790 merely has a pre heater, which essentially serves the same function as glow plugs. The icon on the dash shows a little heater coil as the picture. It is printed at approx the 5 o'clock position. The bottom edge of the key needs to be turned towards the icon (counterclockwise)

In the old 790 owners manual, it was on page 16-Operating section. Your manual should be the same page or within a page or two.

My 790 has always started without the pre heater down to about 20 degrees. It will "rattle" louder and differently for up to a minute until it warms up. The sound will then quiet down and sound normal. The sounds from the first minute are scary until you get used to them.

Thankyou all for your input

If I could just show you the exact paragraph in manual of my new 3005...here it is, I actually got this off John Deere web site, I am pasting the exact language...

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

See that last line hold key in etc, and that is the exact line in my manual and on jd web site.

I am sure you guys are right, but you can see what my concern was.

Unless they have put a new engine in the 3005 that is a major error. This is what my 790 manual says.

1. Place gear shift lever and range shift levers in the N (neutral) position.

2. Depress clutch pedal all the way down.

3. Push hand throttle lever completely forward.

4. Activate the intake air heater system by rotating the ignition key switch to the preheat position (B), and hold it there for 20 seconds.

5. Rotate key switch clockwise to the start position (C) and start engine.

6. When engine starts, immediately reduce engine speed to 1200 - 1500 rpm.

7. If engine runs rough, repeat this procedure until engine runs smoothly.

and pictures of the key labeling attached. Is this what yours looks like?

Fred: that's how my starting procedure works. If I turn my key to "on", I can push it in to glow. It will also push in when it is in "run" (and running). However, it's very obvious as it's spring loaded. Maybe they just misprinted your manual? (I have no 3000 series knowledge )

 

[RobS]

I'll concur with what the others have said on the 790. Only when it's around freezing or below will I turn the key "left" for 10 seconds or so before starting normally. All other times, I just let 'er rip and all is well.

It's either a misprint or there is an entirely different arrangement on the 3005. Does your key actually push in and is it labeled as such on the dash? Glow plugs ought to be pretty obvious on the engine, if you knew what to look for.

Might be worth a call to the dealer, though they may have to call tech support for clarification.

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?
