Part of the Yanmar Parts Manuals.
Strip the injection pump off a 4TNE94 and you are holding a stack of small parts that must go back on in order, each with its own number when one turns out worn. This catalog, Yanmar publication Y00R4570, identifies every one of them for the 4TNE94-SA and 4TNE94-G1A, whatever machine, genset, or pump the engine came out of.
Nineteen sections break the whole engine into numbered drawings and part lists: cylinder block, cylinder head and bonnet, crankshaft and piston, camshaft and driving gear, the lubricating oil and cooling water systems, injection pump, injection valves, fuel lines, feed pump, governor, starting motor, generator, and a complete gasket set.
Ordering by guesswork costs twice, once for the part that does not fit and again for the days the engine sits apart waiting on the right one. This PDF downloads instantly and puts the correct number against the drawing before you pick up the phone.
