The 4BTA3.9-C130 is a complete four-cylinder diesel engine assembly from the Cummins B series, rated at 130 hp (approximately 97 kW). Built on the 3.9 litre (239 cu in) platform with a 102 mm bore and 120 mm stroke, it is turbocharged and jacket-water aftercooled, making it a proven powerplant for excavators, drilling rigs, agricultural machinery, trucks and generator drive applications.

It is the rating code, and it stands for 130 horsepower rather than for a displacement or a build number. The same 3.9 litre block is also sold as C100, C110 and C125, so the code tells a buyer how hard the engine is rated, while the CPL and the plate tell them how it is built.
Because the governed speed belongs to the CPL, not to the rating code. One C130-II sheet carries CPL 2093 at 2200 rpm while another build is quoted at 2500 rpm, which matters when the engine drives a pump, a drilling rig or a generator that has to hold a fixed speed.
No. The displacement and the rating may read the same, but the QSB version is electronically controlled with an ECM and a common rail system, while the 4BTA3.9 is mechanically injected. Pumps, injectors, harnesses and governors are not interchangeable between them.
3921393 is the head gasket for the eight valve 4B, 4BT3.9 and 4BTA3.9, 3804896 the gasket kit, and 3919357 the head assembly.
3802982, 3971965 and 4948366 are listed across 4B and 6B applications.
