2006 D5N XL - 2 issues

Hey guys, recently bought a 2006 cat D5N xl. Just got to running her on a job. 1.) I'm new to the finger tip steering. Seems real finicky, ill ease into the paddle without much response, then ill increase pressure and itll lock up the track and mack a noticeable sound when it locks up. Both sides make the same audible sound when they are used to do a quick turn. Is this normal on these machines? I realize these controls are going to take time to learn, but concerned of a bigger issue if i ignore the signs if any. Most of my dozer time is on hydrostatic drive.

2.) Second issue i noticed was the hydraulic oil temp gauge isnt reading any increase in temp. Ran machine for 5 hours straight. Is there any way to check this? Replace sending unit? Where is sending unit located?
Thanks for any input!

G..G..G..Granville.........!! Fetch your cloth.
Couple of things ...........

1. Post a Serial Number.
2. How good are you at diagnosing electrical systems..? Do you have a digital multimeter..?
3. On the dash panel, does the SERV CODE icon stay lit after the first panel test when you turn the key on, or does it go out..?
4. The clutch disengagement and brake engagement is adjustable (fingertip control levers). I'll have to find the info but I know that it will require the use of a Click Box. I suggest that you go to the Shop Talk forum and read up about what it is and how to make one.

Nige,
I was hoping youd respond!
1.) Ill get serial number later today.
2.) Yes on MM and I should be able to handle the instructions u provide to test.
3.) That's the strange thing. Machine starts up, no error codes. I read in operations manual behind seat to check what the different symbols mean. I believe the exclaimation mark is a category 1 warning? It was on due to low voltage because of the cold and lack of use. That light and all others go out now though.
4.) Nige, i have read other threads where u and others talked about the click box. Im not so concerned about adjusting the clutches and brakes, but rather do you think what im explaining is a normal result....specifically is the audible noise normal when the brake fully engages and locks up the track.
Now maybe I'm thinking too much, but it seems like if I have the Deaccelerator pedal depressed at all, that the fingertip steering is less responsive than if I'm strictly moving forward or reverse and at full speed in 1st 2nd or 3rd gear it seems to respond better. Ill depress padle ever so slightly and itll turn in desired direction.

Thanks Nige!

I ran a D6M that was new. My first fingertip steering experience. The brakes were set too tight at the factory. A Patton Tractor Tech had to come out three times until he had it adjusted correctly. It was a really nice machine to run after that.

Here's the Electrical Schematic. Go to Grid J-4 on Page 14. There you'll find the Powertrain temp sensor 145-7028. I suggest that you check continuity on the 443 yellow wire up to the dash panel and also make sure that you have a good ground on wire 201 Black.

When the paddle steering nubs are adjusted correctly you have a very nice machine to run. When they are sudden you get the tracks slapping hard whenever you go to steer the machine. The machines without a top roller are worse.

Is it your opionion they are possibly just out of adjustment? I love running the machine! Its a beast and fast as hell! I try to be attentive to my equipment, they all give you a sign or sound thats something is not just right!

That's what Nige was talking about with the Clicker box. I've only seen them adjusted using the laptop and the software but I'm sure there is something in there for the Clicker box. At any rate it has something to do with gain on the controls which is adjustable.

Once we got his powertrain temp sensor sorted out the next thing i was planning on sorting was correct track tension and whether or not it was equipped with track carrier rollers.

On a sidebar I note that it was originally built in 2005 with SystemOne undercarriage. Does it still have that style or has it been converted to heavy-duty undercarriage at some point in time..?

I've had a look at the Test & Adjust and the steering clutches/brakes can be set up using a Clicker Box.

Plan is to check sensor on monday. Earlier if possible. Machine definitely has a carrier roller. While operating i noticed the right hand or passenger side track looked looser than the left side. Track tension might very well be a cause.
I know when i bought the machine, the undercarriage was like new. Only had 300hrs on it and they changed everything. I think the aftermarket undercarriage was itr parts.

Do you have an operator manual..? If not you should get one ASAP - less than $50 to download from Cat.
It has the specs for correct track tension.

You'll never get the track to hang exactly even as shown in the diagram. The average of measurements #3 and 4 should be 2.25" +/- 0.25".

Also if the undercarriage is aftermarket ITR then what exactly is it, their version of SystemOne or "conventional" heavy-duty undercarriage..?
I don't have all the information to hand but from what I recall there is a fair amount of work involved to change a machine from SystemOne to heavy-duty undercarriage, including changes to the track guiding guard arrangement. If not all these changes were made then there is a possibility that mismatched undercarriage components could be affecting steering clutch/brake performance (noise, harshness..?) during operation.

I do have operators manual. I'll try to retrieve the part numbers off the chains and rollers.
Is there any way to know by looking at the tracks visually if they are HD or system one? What's the difference between the 2?

Nige,
Thanks for all the help, you were 100 percent right with the adjustment of the tracks. The right track was at least an inch and a quarter out, left was 3/4 inch out. We adjusted accordingly and the machine operated completely different! Feels much better and normal. I don't hear the knocking or roughness i felt before.
I ordered the sensor and Cat is telling me it's on order till early March? I hope the worst is the sensor is bad.
I still haven't had a chance to check the continuity, will keep posted on results.
Thanks again to all the guys on here, lots of respect to you!
