Cat Pistons, Rings, Liners, and Rods
New Caterpillar Pistons, Rings, Liners, and Rods are designed and
manufactured using quality materials and controlled processes for
maximum performance and durability.
Quality materials and controlled processes ensure top performance and long life
Improved structural capability of the
single piece forged steel piston
simplifies assembly and eliminates
the number of parts.
New oil jet with higher oil velocity
provides more concentrated cooling.
Reduces thermal expansion and
allows piston fit to be tighter for a
reduction in cavitation.
Reduction in surface area provides
less friction and helps improve fuel
consumption.
Precise plasma or chrome plating guarantees
exceptionally long wear life.
Proper surface finish provides smooth
operation and long wear life.
Barrel-faced top ring maintains the proper
oil film thickness on the cylinder liner for
reduced liner damage and oil consumption.
Durable heat-treated ductile iron constructionresists breaking and impact loading.
Precise fit with grooves ensures proper oil
control and sealing between the crankcase and
combustion chamber for efficient operation,
long wear life and reduced blow-by.
One Piece Pistons
Inside surfaces feature a uniform cross hatch
pattern for faster ring seating, proper ring
seal, uniform oil distribution, and long life.
Flanges are roll burnished in the radius for
increased strength and resistance to cracking. Heat-treated high-grade gray iron construction
provides exceptional strength and long life.
Controlled flange head thickness guarantees a
precise match with the block and head.
Precise manufacturing tolerances ensure
perfectly round bores for efficient oil control
and proper fit in Cat engine blocks.
Cat Liners
Cat Rings
Fractured Rod Perfectly matched joint surfaces allow rods toaccept higher loads.
Fractured uneven surface helps locate rod end
and cap, eliminating the need for locating
dowel.
Automatic bolt insertion and fastening
equipment ensures cap and rod stay together,
eliminating possibility of mismatched cap and
rod during material handling.
Two Piece Piston Two piece articulted design forreduced piston slap, better combustion
and reduced emissions due to rings
located closer to the top of the piston.
Steel crown for heat resistance, and
higher cylinder pressure. Aluminum skirt for weight reduction.
Chrome
Ceramic Ring
Coating of several layers of hard chromium
for higher scuffing resistance.
A network of tiny micro-cracks on each layer
for better thermal fatique properties.
Ceramic particles embedded into each layer
of chrome improves consistancy propertiesover the entire coating depth.
Normal chromium wear exposes new ceram-
ic particles resulting in less surface crack-
ing/ring flaking, reduced wear of both ring
and cylinder bore, significant life improve-
ment, and better spalling resistance.

Reman Cylinder Packs reduce downtime and costs
Remanufacturing transforms used Cat
components to new parts standards. When you
need repairs, Cat Reman Cylinder Packs will get
you back to work quickly, reliably, and
affordably. Completely remanufactured to
include all critical engineering updates and
design improvements, Cat Reman Cylinder
Packs provide same-as-new performance and
long life.
Strict remanufacturing processes
New articulated piston bushings are installed
using correct installation methods to ensure
retention of bushing in bore.
New liners and rings are installed for exact
fit and smooth operation.
All components are extensively tested
and inspected for conformance to factory
specifications.
Fast, easy installation
Cat Reman Cylinder Packs contain the cylinder
liner, piston, rings, pin, retainers, connecting
rod, and all necessary seals. They comepreassembled and ready for installation as a
unit, reducing your turn-around time.
Plus, our special tooling and repair technique
can save up to an hour per cylinder during
installation, so its possible to complete an
entire in-frame overhaul in one day. No other
engine manufacturer offers this kind of service.
Fully warranted, low-cost repair
options
Cat Reman Cylinder Packs are priced at 45-50%
of the cost of new parts and offer the samefactory-fresh performance. To prove i t,
Caterpillar backs Reman Cylinder Packs
with a same-as-new parts warranty.
Caterpillar randomly tests competitive
parts to determine quality differences.
These comparisons consistently reveal
the following shortcomings about
competitive pistons, rings, and liners.
Competitive pistons Imprecise fit can cause liner scuffing
and piston seizure.
Partially disbonded ring bands andout-of-spec ring grooves can cause
blowby and cylinder damage.
Competitive rings Thin chrome plating can reduce
wear life.
Soft, gray iron construction can
reduce durability and lead to failure.
Competitive liners Lack of heat treating and roll
burnishing can lead to flange cracksand breaks.
Random cross hatch pattern can result
in poor oil control and increased oil
consumption.
