S4Q, S4Q2, S4Q-2, S4QT and S4Q2-T all appear as build names, and S3Q and S3Q2 are the three cylinder versions. One listing carries eight designations on a single line, naming S4Q2, S4S, 4M50, 4D36, 4D33, 4M42, 4AT2 and S3Q2, repeated word for word by a second supplier at an identical price.
Figures include 28 kW and 30 kW at 2500 rpm on forklift sheets, 32.7 kW or 44.5 hp for the construction machine build, and market listings quoting 34.6 kW at 2400 rpm and 37 kW at 1600 rpm. The rating belongs to the build and has to be fixed before the quotation.
The engine appears in forklift specification sheets for the 1.5 to 3.5 tonne trucks, is sold as a construction machine engine, and the indirect injection head is listed for compact tractors. The machine it comes out of decides the build.
The glow plug 32A66-03102 is listed for S4L, S4L2, S4Q-2, S4S, S4Q2 and the K4N and K4A to K4F engines in one line. A shared small part does not make the complete engines interchangeable.
Complete assemblies here are advertised mostly between about USD 1,450 and 5,400, with figures near 490 that cannot describe a complete engine and a pair of listings near 9,000. Prices are quoted per piece, per set and per bag.
Petrol car engines such as the 4A15, 4A92, 4G15S, 4G18, 4G63T, 4G64, 4B12, 6B31 and 6G73 appear in the same search, as does the 4D56T. They are unrelated, and the capacity has to be checked against the 2.5 L industrial unit.
