Part of the Yanmar Operator Manuals.
Air trapped in the fuel lines will keep a JH series diesel cranking all day without a single fire, and the bleeding procedure that ends it lives in the Before You Operate section of this manual. Yanmar issued it as publication 0AJHM-M00201 for the 3JH5E, 4JH5E, 4JH4-TE, 4JH4-HTE1 and 4JH4-HTE marine engines built from 2009 through 2013: 168 pages, in English.
It covers what keeps these engines alive between rebuilds: diesel fuel and engine oil specifications, coolant mixing limits, marine gear and sail drive oil checks, the periodic maintenance schedule, cold weather starting, long-term storage, and a troubleshooting chart keyed to symptoms. A full set of piping and wiring diagrams closes out the book.
Guess at a coolant mix or stretch a filter interval and the price is a cooked cylinder head or a dead engine a long way from the slip. The PDF carries 131 bookmarks, so the procedure you need is two clicks from the cover.
Complete the set for your 3JH5E / 4JH5E Series
