The Caterpillar 140H motor grader was introduced in 1995 in the USA, Australia, and Brazil. Production began in China in 2005.

[edit] Features

The 140H has a 3306 turbocharged engine producing 150 or 185 flywheel horsepower (FWHP). It has an eight speeds forward, six reverse direct drive powershift transmission with electronic control.

The 140H was manufactured in the USA, with a 2ZK, 8JM, or 8KM serial number prefix; in Australia, with a 9ZN prefix; and in Brazil, with a 3AS, 5HM, or 9TN prefix. The 8JM, 8KM, 5HM, and 3AS units have engine power management. All others have variable horsepower.

The 9ZN, 3AS, 9TN, 8KM, and 2ZK units have integrated engine compartment doors and a contour seat.

[edit] Modifications

In 1996 Caterpillar made an emission-regulated engine standard on two American units, beginning with 2ZK00656 and 8KM00375. All American units received extended life coolant, beginning with 2ZK01204, 8JM00261, and 8KM00394.

Production of 8KM ended in 1996.

In 1996 and 1997 Cat added radiator cleanout access covers and new battery boxes, and modified the fuel sending unit, beginning with 9ZN00151, 3AS00400, 5HM00800, 9TN00120, 2ZK01717, and 8JM00270. At the same time, the 3AS, 5HM, 9TN, 2ZK, and 8JM units had modifications made to their drawbar to improve visibility. The 3AS and 9TN units also received emission-regulated engines.

In 1997, scheduled oil sampling ports, a circle drive slip clutch, and an optional 12-volt power port were added, beginning with 3AS00450, 5HM01150, 9TN00300, 2ZK02392, and 8JM00280. At the same time the 3AS, 9TN, and 2ZK units had their oil filter access improved, and received optional autoshift. The Australian unit modified its oil filter access, and received optional autoshift and an optional 12-volt power port, beginning with 9ZN00205.

In 1998 variable horsepower was increased to 165 or 185 FWHP, beginning with 9ZN00261, 3AS00479, 5HM01412, 9TN00801, 2ZK03446, and 8JM00291. A four-legged spider gear replaced the three-legged spider in the differential along with a single piece bearing cap to improve the differential’s service life, beginning with 9ZN00264, 3AS00474, 5HM01406, 9TN00797, 2ZK03481, and 8JM00295.

In 1999 the differential spider gear bearing material changed from aluminum bronze to manganese bronze to decrease the material transfer from the bearing to the spider leg, beginning with 9ZN00339, 3AS00508, 5HM01487, 9TN01012, and 2ZK04488.

In 2000 Cat modified the lower ripper link to improve its service life, beginning with 3AS00563, 5HM01607, 9TN01043, and 2ZK05156.

In 2001 final drive sun gear shafts were replaced, beginning with 9ZN00420, 3AS00589, 5HM01746, 9TN01054, and 2ZK05796. The fan spider was modified, beginning with 9ZN00427, 3AS00593, 9TN01054, and 2ZK05711.

In 2002 and 2003 Caterpillar introduced new 140H units in the USA, with an APM prefix; in Australia, with a 126 prefix; and in Brazil, with CCA prefix.

The new American and Brazilian 140H units have a 3176 electronic engine with air-to-air aftercooling (ATAAC) producing 165 FWHP. They come standard with a serpetine belt with automatic tensioner, a fuel water separator, enhanced vehicle styling, 500-hour oil change interval, modified remote engine oil drain, on-demand hydraulically driven “pull” fan, inside mounted air dryer, ground level fueling, left hand side centralized service access, sample ports on all systems, ground level coolant check, a “lube-for-life” pump drive shaft, EMS III (electronic monitoring system), automotive-style fuses, electronic throttle, increased cab air flow to the windshield, electronic transmission directional solenoids, and LED stop/turn lights. They are also available with three-level variable horsepower.

The Australian unit has a 3176C engine with variable horsepower, an electronic clutch pressure control (ECPC) transmission, and electronic controls.

In 2004 and 2005 a new final drive was added and preload was adjusted, beginning with 9ZN00684, 5HM02147, 9TN01568, 2ZK07850, and APM00274.

Production began in China in 2005, with a XZH prefix. It has a Cat 3306 engine producing 150 to 185 variable horsepower. It comes standard with an eight speeds forward, six reverse countershift transmission.

In 2005 a larger transmission filter was added, beginning with CCA01867.

In 2006 Cat modified the circle pinion, beginning with 5HM02915, CCA01956, XZH00243, and APM02514. An AccuGrade ready option became available, beginning with CCA01611 and APM02223.

Based on data from the sales database of Ritchie Bros. Auctioneers, it is estimated that more than 14,200 Caterpillar 140H motor graders have been produced.
