Caterpillar 160H Motor Grader
The 160H has a 3306 turbocharged engine producing 180 or 200 flywheel horsepower (FWHP). It has an eight speeds forward, six reverse direct drive powershift transmission with electronic control. It comes standard with a PPPC hydraulic system, and a modified operator compartment and blade position.
The 160H was manufactured in the USA, with a 6WM, 9EJ, or 9JM serial number prefix; and in Brazil with a 2FM, 2HS, or 3GM prefix. The 2FM, 2HS, 6WM, and 9JM have engine power management. All other units have optional variable horsepower.
The 2HS, 3GM, 6WM, and 9EJ units have integrated engine compartment doors and a contour seat.
In 1996 Caterpillar made an emission-regulated after-cooled engine standard, beginning with 6WM00337 and 9EJ00254. Extended life coolant was added, beginning with 6WM00341, 9EJ00323, and 9JM00330.
Production of 6WM ended in 1996.
In 1996 and 1997 Cat added radiator cleanout access covers, larger articulation hydraulic cylinders and new battery boxes, modified the fuel-sending unit, and adjusted the drawbar to improve visibility, beginning with 2FM00350, 2HS00350, 3GM00050, 9EJ00420, and 9JM00340. At the same time the 2HS and 3GM units received emission-regulated after-cooled engines.
In 1997, scheduled oil sampling ports, a circle drive slip clutch, and an optional 12-volt power port were added, beginning with 2FM00400, 2HS00380, 3GM00080, 9EJ00510, and 9JM00350. At the same time the 2HS, 3GM, and 9EJ units had their oil filter access improved, and received optional autoshift.
In 1998 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 2FM00485, 2HS00384, 3GM00088, and 9EJ00624.
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 2FM00502, 2HS00390, 3GM00091, and 9EJ00765.
In 2000 Cat modified the lower ripper link to improve its service life, beginning with 2FM00509, 2HS00396, 3GM00095, and 9EJ00855.
In 2000 and 2001 final drive sun gear shafts were replaced, beginning with 2FM00526, 2HS00398, 3GM00095, and 9EJ00933. The fan spider was modified, beginning with 2FM00530, 2HS00398, 3GM00097, and 9EJ00929.
In 2002 Caterpillar introduced new 160H units in the USA, with an ASD prefix; and in Brazil, with a CCP prefix.
The new 160H units have a 3176 electronic engine with air-to-air aftercooling (ATAAC) producing 180 FWHP. It comes 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. It is available with three-level variable horsepower.
In 2003 steering accumulators were added, beginning with ASD00160.
In 2004 and 2005 a new final drive was added and preload was adjusted, beginning with 2FM00701, 3GM00206, 9EJ01295, and ASD00199.
In 2005 a larger transmission filter was added, beginning with CCP00311 and ASD00556.
In 2006 Cat modified the circle pinion, beginning with 2FM00900, CCP00312, and ASD00536. An AccuGrade ready option became available, beginning with ASD00603.
Based on data from the sales database of Ritchie Bros. Auctioneers, it is estimated that more than 2,700 Caterpillar 160H motor graders have been produced.
