    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.
