DGI Australia’s ongoing component guide series outlines how to quickly and accurately identify or upgrade major OEM components.
This month, we’re highlighting how to easily and effectively modify a Caterpillar 777B transmission to suit a later-model 777C or 777D model truck. We’ll also shine a light on the similarities and differences between the differential and bevel gear, which are able to spec up to an E series truck with further modification.
A testament to the sound design and engineering implemented across Caterpillar’s range of trucks, the modification involved in this upgrade is relatively simple.
A 777B contains transmission 9W-9303, while and 777C and 777D run the 8E-9035 transmission. To update the 9W-9303 to the 8E-9305, simply install the updated hydraulic control valve.
A Caterpillar 9D-2315 777B differential and bevel gear contains the diff centre 6G-7506. Similarly, 777C, D and E model trucks contain the same 6G-7506 diff centre within their differential and bevel gear assembly, with the part number 104-9410.
The major point of difference here, among smaller necessary modifications required to upgrade, is the main housing.
