John Deere's component technical manual CTM93 for the 6076AFD dual fuel engine, covering the natural gas and diesel fuel system that sets this engine apart from a standard diesel 6076. It explains the ECU, link controller and governor theory of operation, system diagnostics, repair and adjustment, and is meant to be used alongside the general 6076 engine manual, CTM6.

This component manual (CTM93, dated 26SEP94) is written for the 6076, 7.6 L (466 cu in) dual fuel engine, built by John Deere in Waterloo, Iowa, and set up to run on either natural gas or diesel. It is a component manual, meaning it covers only the systems specific to this engine's dual fuel setup rather than general engine teardown.
John Deere directs technicians to pair this book with three others: CTM6 for general engine repair, CTM68 for electronic fuel injection diagnostics, and CTM77 for the charging and starter systems. That division keeps this manual focused entirely on the parts unique to dual fuel operation - the ECU, the natural gas governor, pressure regulator, metering valve, rotary actuator, shutoff solenoid, link controller and the sensors and wiring that tie them together.
Crankshaft rotation in this manual is referenced from the flywheel end looking toward the front, with the fan drive end as the front of the engine. Clean and mount the engine on a repair stand before beginning teardown, per Group 03 of CTM6. 100 pages.
