**Engine Performance** is corrected to inlet air standard

conditions of 99 kPa (29.31 in. Hg) dry barometer and

25°C (77°F) temperature. These values correspond to

the standard atmospheric pressure and temperature as

shown in SAE J1995.

Performance measured using a standard fuel with fuel
gravity of 35 degrees API having a lower heating value of

42,780 kJ/kg (18,390 BTU/lb) when used at 29°C (84.2°F)

where the density is 838.9 g/L (7.001 lb/U.S. gal). The corrected performance values shown for Cat engines

**52 in.**The Cat 3406 is an in-line, six-cylinder diesel built to last, with major components offering an exceptionally high strength-to-weight ratio. With power ratings from 199–392 bkW (267–525 bhp), this hard-working powerhouse offers reliable power for a wide range of heavy-duty applications.

Lasting Performance is Built In The one-piece cylinder heads resist twisting and flexing that can cause head gasket problems and coolant leaks. A steel spacer between the head

and block eliminates the need for liner counterbores, greatly enhancing the strength and fatigue life of the block.

The forged steel crankshaft is uniquely heat-treated in a process developed and patented by Caterpillar. Then it is dynamically balanced and super-finished. The crankshaft’s high fatigue strength means it can be reground up to three times.

Hard-faced intake and exhaust valves resist wear at high heat, while the chrome-plated stems help guard against seizure. Valves rotate three degrees each lift, assuring good seating and uniform temperature distribution.

Simplified Service and MaintenanceThe direct injection fuel system uses adjustmentfree injection nozzles. Spin-off fuel and lube filters and clamp-on air filters speed routine maintenance procedures.
