THE KEY TO LONGER WEAR LIFE IS BALANCE

CAT HDXLFOR D9-D11DOZERS
High-load, high-impact conditions. That’s the mining industry.
You and your dozers have tough jobs to tackle. And to get thework done right, you need equipment that takes heavy duty one
step further. Rigorously innovating. Constantly improving.
That’s what “Cat® Heavy Duty Extended Life” is about.
And all that pays off when it comes to the performance,
profits and productivity that come out of it.

HDXL UNDERCARRIAGE WITH DURALINK+ High-quality materials and carefully controlled manufacturing
processes deliver reliable, durable components that wear ata balanced rate.

You can’t just change one component of a track and expect
everything to work out. So, aside from the crowned link design,
this track is engineered with larger bushing to balance thebushing-to-link life, and to enhance oil retention, it’s with coatedwith XL Sealing technology.

THE SLEEVE BEARING TRACKDESIGN MAXIMIZES LIFE AND
MINIMIZES DOWNTIME
With more than two decades of proven performance in the field,
the patented Cat Sleeve Bearing Track design has demonstrated
its ability to eliminate galling, improve joint performance andkeep your machines working when you need them.
+ STANDARD and only available on D11 Track-Type Tractors+ DESIGNED to operate at higher speeds and greater loads+ ELIMINATES galling between pin and bushing+ INCREASES track reseal point to 8,000 hours on HDXL
Because it extends undercarriage life, the need for service before
normal bushing turn time is also reduced — reducing maintenancecosts and unscheduled downtime. Like all Cat tracks, it’s built tolast. Longer life and predictable wear mean you get maximum
performance at the lowest possible operating cost.

+ Longer life and predictable, manageable wear mean you getmaximum undercarriage performance at the lowest possible
operating cost, with planned downtime instead of surprises.
+ Larger diameter bushing with XL coating that significantly
improves corrosion resistance, extending the reseal point to8,000 hours.

D9-D11POSITIVE PIN RETENTION (PPR)ON YOUR HDXL TRACK KEEPS THOSE
HIGH IMPACT APPLICATIONS ON LOCKThe PPR design on the HDXL track features specially machined links
and pins that allow for the use of a metal retaining ring. This ring ispressed into the groove between the pin and link, locking the joint in place.
This prevents the outward movement of the links on the pin — which isespecially important in high-impact applications.

THE CATERPILLAR EXCLUSIVE CROWNEDDURALINK DESIGN IS A GAME CHANGER+ By design, it reduces the rate of scalloping by 50%.
+ The crowned link places additional steel where it’s mostneeded to extend wear life.
+ This crowned link delivers thousands of operating hours
before wearing to the starting point of competitor tall links— delivering unmatched results.

This exclusive Caterpillar design is recommended for applications
that generate high impact loading such as mining, heavy construction,
demolition and waste disposal. Machines equipped with wider shoes,Extreme Service shoes or Super Extreme Service shoes should also
consider PPR track.

MATCHED FOR HDXL UNDERCARRIAGE
Balanced wear on components
MORE MATERIAL ON TREAD+ Up to 40% more material added to the roller
diameter1+ 2 5% more material added to the idler diameter 2A large dozer taking on tough conditions needs a large roller and idler
built to match. It just makes sense. And that’s why Cat Heavy Duty
Extended Life (HDXL) rollers and idlers were created.
With more wear material, you’ll literally get an “extended life” out of yourundercarriage. And we all know that means less machine downtime andmore time in the work.

+ LONGER wear life
+ LOWER cost per hour

CAT SUPER EXTREME SERVICE(SES) TRACK SHOES
A big dozer working in hard rock generates extreme stresses on track shoes.
To take the punishment, the shoes need more wear material and beefier
construction. That’s exactly what you get with Super Extreme Service (SES) shoes.
Exclusive to Caterpillar, SES shoes feature up to 30% more wear material andspecial construction features — delivering maximum uptime and extended track
life, while reducing service needs.
