Terex TA40 OCDB (A820) — Terex TA40 Articulated Dump Truck Maintenance & Service Manual (EN)

General Information - Technical Data Section 000-0000 Ratios: Torque Converter .................................................... 1.84:1 Transmission .................................... Refer to table below. BRAKES Full hydraulic braking system with enclosed, forced oil- cooled multiple discs on each wheel. Independent circuits for front and rear brake systems. Warning lights and audible alarm indicate low brake system pressure. Brake system conforms to ISO 3450, SAE J1473. Actuating Pressure ........... 138 ± 6.2 bar (2 000 ± 90 lbf/inІ) Pump Type ................................................ Triple stage gear Capacity at 2 200 rev/min ......

2.02 litre/s (32 US gal/min) combined Braking surface (tractor) .....802837 mm 2 (1244.4 in 2 )/brake Braking surface (trailer) ........ 535225 mm 2 (829.6 in 2 )/brake Parking: Spring-applied, hydraulic-released disc on rear driveline. Emergency: Automatic application of driveline brake should pressure fall in main brake hydraulic system. Service brakes may also be applied using the parking-emergency brake control. Note: During reversing operations it is recommended to reduce engine speed, use only 1st or 2nd gear and never exceed 10 km/h (6.2 mile/h). AXLES Retardation: Hydraulic retarder integral with transmission.

Three axles in permanent all-wheel drive with differential coupling between each axle to prevent driveline wind-up. Heavy duty axles with fully-floating axle shafts and outboard planetary gearing. WHEELS AND TYRES Wheels ...... Five-piece Earthmover rims with 23 Stud Fixing Size: Standard .......................25 x 25.00 in for 29.5 R25** tyres Tyres: Standard ...............................................29.5 R25** Radial Automatic limited slip differentials in each axle. Leading rear axle incorporates a through-drive differential to transmit drive to the rearmost axle. Locking of this differential is actuated simultaneously with the transmission output differential lock.

Inflation Pressures (Bridgestone): Front Rear 29.5 R25** 3.5 bar (51 lbf/inІ) 4.25 bar (62 lbf/inІ) Ratios: Differential ............................................................... 4.86:1 Planetary ................................................................. 4.94:1 Total Reduction ....................................................... 24.0:1 Inflation Pressures (Continental): Front Rear 29.5 R25** 3.5 bar (51 lbf/inІ) 4.25 bar (62 lbf/inІ) Inflation Pressures (Michelin): Front Rear 29.5 R25** 3.0 bar (44 lbf/inІ) 3.65 bar (53 lbf/inІ) SUSPENSION Front: Axle located by a leading A-frame permitting both vertical movement and oscillation.

Rubber cone suspension medium with heavy duty hydraulic dampers. Note: Tyre pressures should be regarded as nominal only. It is recommended that for tyres both listed and unlisted, the user should consult the tyre manufacturer and evaluate all job conditions in order to make the proper selection. Axle Vertical Travel .................................. 105 mm (4.2 in) Rear: Each axle is coupled to the frame by three rubber- bushed links with lateral restraint by a transverse link. Pivoting inter-axle balance beams equalise load on each rear axle. Suspension movement is cushioned by rubber/ metal laminated compression units between each axle and underside of balance beam ends.

Pivot points on rear suspension linkages are rubber-bushed and maintenance-free. HYDRAULIC SYSTEM Steering and Body Hoist The steering and body hydraulic systems are supplied with oil from a common tank by the main hydraulic gear pump. Pump is driven from power takeoff on transmission. The components are protected by advanced full flow filtration to 5 micron particle size on the return line. Axle Vertical Travel ............................± 115 mm (± 4.5 in) Axle Oscillation ............................................................± 9° Pump capacity (at 2258 rpm).......................
