Tailored Support for High-Value Assets
From 777-series trucks operating in mid-tier applications through to 793F models driving high-production output, DGI supports a broad spectrum of Caterpillar platforms. Our experience spans multiple generations of assets, including the 777C, 777D, 777E, 785B, 785C, 789C, 793C, 793D and 793F.
We also support 769C, 769D, and 785D models in use across diverse mining regions.
Component Coverage That Aligns with Operational Strategy
We maintain availability across major component groups essential to Caterpillar truck operation, with dedicated inventory streams and supply capability for:
- Powertrain systems – transmissions, torque converters, differentials and final drives for 777E, 785C, 789C, 793D and 793F models. Each component is selected and verified for platform compatibility, performance integrity and operating hour targets.
- Suspension and structural assemblies – including A-frames and front suspensions for 785 and 789 trucks. We maintain interchangeable inventory to service both early- and late-model fleets, reducing delays associated with engineering revisions and supply shortfalls.
- Hydraulic and braking systems – including steering cylinders, brake calipers, accumulators and suspension struts. These are supplied to suit fleet configurations across the 777D, 785B and 793C, ensuring compliance with OEM performance benchmarks and safety parameters.
- Tray assemblies and wheel groups – DGI supports tray supply and rear wheel group options for 789C and 793D machines, including EL (Extended Life) wheel groups that offer reduced service intervals and extended wear cycles in abrasive haul conditions.
- Engines and cooling modules – Our support extends to Cat C27 and C32 engines used across the 777 and 785 platforms, along with radiator cores and fan assemblies configured to suit differing site altitude and temperature ranges.
Applied Expertise That Reduces Operational Risk
DGI Trading is not just a supplier — we are a strategic partner in equipment lifecycle management. Our technical advisors assist customers in identifying correct parts across truck variants, such as confirming interchangeability between 785C and 785D component groups, or assessing the operational impact of transitioning from a 793C to a 793F fleet.
Where multiple truck generations are operated within a single asset base, this level of technical clarity reduces misallocation risk and supports maintenance standardisation. We also offer insight into component updates and engineering changes that may affect service compatibility across legacy fleets.
Through a global procurement network and responsive local warehousing, DGI ensures that critical Caterpillar truck components are ready for dispatch — reducing downtime and increasing certainty for your maintenance program.
