D6R XW serial number low production run

Bullcat · Dec 12, 2015

I recently purchased a D6R XW serial #DMP00200. My other tractors are 9G 66A, 8H 46A, 7G 92V, 4H 9DB, so I'm learning all I can on this machine. I looked the serial number up on ironrecord.com and it shows that it is a XL machine but mine is badged XW and has the wider shoes and XW blade, was it born an XL or is the info on ironrecord.com just in general to the different arrangements. Also it shows a total production run of 214 machines from 2001 -2002. Why were there so few of these produced?

Your particular tractor Serial Number is listed on the system as a D6R XW (all DMP-prefix machines are). It was built on 8th October 2001 with a 4Z-0642 Semi-U bulldozer arrangement S/N 1WP-02823. You should find the S/N plate on the back side of the blade in the top RH corner. If the plate is missing the S/N should be stamped in the same location. As a a 2nd possibility some smaller bulldozer blades had the S/N plate lower down in the centre of the blade.

Track Groups are 1Q-4736 Sealed & Lubricated Heavy Duty Link Groups fitted with 30"-wide 6Y-8973 Moderate Service track shoes. For Field Replacement complete track groups order 2 x 385-5433.

Engine S/N - 6NC29352
Transmission S/N - 8KY01458

I ran a D6RXW with a "Special Product" badge, I don't know much about it, but it WAS the "Pushingest" dozer over EVER RAN, pound for pound!

Do you mean "Custom Product" badge..?

This dates from years ago when the Cat Custom Shop would produce a machine for any application by taking a standard model and modifying it to produce a machine that satisfied the customer's needs. All the modified attachments used on the machine were given Custom Shop Part Numbers that always used the letters Q & Z. No other Cat departments use those letters. The fact that that D6R in the OP has a 4Z Blade Arrangement and a 1Q undercarriage makes it a Custom Product therefore it will be fitted with the badges to prove it - unless someone has removed them to fit on a toolbox that is. They used to be very popular toolbox adornments.

Nige, thank you for the information. I checked the numbers on the blade and they match the number you listed. So is this tractor different in some way compared to other tractors? Where would the custom badges be and what do they look like? I have had a chance to run it building some terraces and have to say that I am very impressed with what it can do. Its very tied to the ground and the 3306 wants to push full blades while cutting in 2nd without sweating. It puts my D7g to shame. I've never ran another 6h or 6r for comparison but I'm seriously impressed with this one.

I had to look in my archives to find a photo showing the Custom Product badge. It's about 4" long by 3" high and on a dozer it should be mounted either above the fenders or maybe even on the sides of the hood. As I said before they were at one time prized possessions to put on mechanics' toolboxes and very few of them last long in the field.

We have a d10r that used to have them and I ran a d6r XW that had it too was an interesting machine. The 10 is also a real strong pusher.

Hello Bullcat,
I'm quite sure that most of the people on here are more knowledgeable than I, but I have encountered one of these machines before. The "XW" arrangement means that they track frames are pushed out wider to accept wider shoes, but not quite so wide as an LGP dozer. It's a sort of middle ground between a normal D6 and a D6LGP.
Other than that I believe they are the same as a normal D6.

I don't remember ever seeing an XW machine with and SU blade. All I've seen had PAT blades. Maybe this was a custom set up?

I ran a 6T XW this spring. Thought it pushed pretty good, but quite a step down in pushing power from the 7H. But, not nearly as big a gap as there is between a 8R and the 7H obviously.

So could it be that these 214 serial #DMP****** tractors were the first run of the XW machines and it basically consisted of shoe size between XL and LGP, and a wider blade than XL and higher hp. And that is what made it a custom product until the XW series II came out. Thanks for everyone's input, I've learned something new.

Desertwheeler · Dec 14, 2015

The XW we had also had vertical lift cylinders and a 6 way blade what they call that?

oldirt · Dec 14, 2015

the tractor I was referring to had a 12' blade and wider push blocks installed on the roller frame to accommodate the wider blade. Denny told me he worked next to a 7G on occasion and noticed there was little difference of output between the two. it also was badged "XW".

Far be it from me to throw cold water over these ideas, but ponder this ........ LGP machines have 30" wide shoes, so does the DMP-prefix machine. LGP machines have a wider track gauge to accomodate the 30"wide shoes and so does the DMP-prefix machine. What makes the machine a Custom Product is the 4Z-xxxx Blade Gp, and the 1Q-xxxx track group. both of these numbers are Custom Shop arrangements but they are standard on this machine.

This will make you laugh. The 789C in the photo in post #7 above got the Custom Product badges for one reason only - the footrest in the LH side of the cab was a 4Z-xxxx Part Number. That small thing made the truck qualify for CP badges .......... go figure.

Yes, Nige you're correct, it was a Custom Product not Special Product.
