Features

Waste Handling Track-TypeTractors

● Center hole track shoes (optional) help minimize the effects of track packing during machine operation. ● Blade trash racks (optional) prevent blade spill-over and damage to cylinders or radiator guard. Increase productivity in waste handling. ● Ducted alternator available on D6T, D8T, D9T insures adequate current is available to maintain battery and operate accessories. Not required on D7E. ● Elevated prescreener to remove engine air inlet from debris environment. Larger surface area to resist plugging. ● Precleaner removes large particulates from incoming air before they reach the air filter, helps extend filter life. (Optional on D6T through D9T.) ● ROPS mounted air conditioning helps prevent con- denser core plugging. Provides full utilization of jacket water cooling system by avoiding additional heat load from radiator mounted condenser. ● Laminated thermal shields cover the CEM inside the engine compartment, hot-side of the turbocharger, and the exhaust manifold. These shields reduce sur- face temperatures below the flash point of most com- mon combustibles encountered. ● Chassis Guards. ● Sealed belly guards . ● Perforated engine enclosures standard on D6T, D7E, D8T, and D9T. This configuration is unavailable when Sound Suppression is ordered. ● Carrier rollers not recommended on elevated sprocket machines.

Cat Waste Handling Track-Type Tractor modifi- cations are purpose built and installed at the original manufacturing facility prior to shipment. Features: ● Hinged heavy duty radiator doors are guarded to pre- vent excessive trash build-up. Quick release handles allow easy access for cleaning. ● Final drive, pivot shaft, and idler seal guarding helps prevent wire, cable and similar material from wind- ing around components and damaging seals. ● Striker bars for front, rear and ripper (all optional) keep trash from damaging fenders, fuel and hydraulic tanks or other sheet metal. ● Lighting protection. Front lights are mounted on top of bulldozer lift cylinders. Rear lights are ROPS mounted. ● Waste Handling Arrangement radiator with 6 fins/inch. ● Elevated sprocket removes final drives from wear envi- ronment and eliminates impact loading for extended power train life. D7E includes D10-size bearings to ensure long life. ● Sheet metal guarding near track and on dozer tilt hoses. ● Fuel tank guards keep trash from damaging fuel and hydraulic tanks or other sheet metal. ● Final drive guards — guard installed over the final drives to help prevent wire wrap. Guards include inspection plates, not available for D6N. ● Reversible hydraulic demand fan required for D6T, D7E, D8T, D9T, not available for D6N. ● Heavy duty steps and grab handles resist damage from landfill debris.
