Part of the Yanmar Operator Manuals.
An air pocket in the fuel line will keep a 4TNE cranking all morning without a single fire, and the troubleshooting chart in this book exists for exactly that kind of day. Around it sit the chapters that keep the engine out of trouble: fuel oil, lube oil and cooling water requirements, starting and stopping procedure, and periodic inspections from the first 50 hours out to every 2000.
The book is Yanmar publication 49961-101301, written for the 4TNE94, 4TNE98, 4TNE106 and turbocharged 4TNE106T four-cylinder industrial diesels, whatever equipment yours happens to power. Engine specifications, part names, instruments and alarm devices are laid out for each model.
A guessed filter torque strips a thread or weeps diesel down the block; this manual gives Yanmar's own figures, plus the spare part numbers worth ordering before the next service. The 48 page PDF prints cleanly, so the copy that lives by the engine can get dirty.
