Volvo suspension system. Totally maintenance-free. Front axle: One rubber spring with bottoming absorption on each side. Stabilizer. Two shock absorbers on each side. The front axle is suspended at three points, allowing oscillating in rough terrain. Bogie: Volvo´s unique rough terrain bogie, which permits individual oscillation between the axles.




Fully hydraulic disc brakes on all axles. Two circuits. Well protected components. Complies with ISO 3450 and SAE J1473 at total machine weight. Service brakes: Dry disc brakes on all wheels. Circuit division: One for front axle and one for bogie axles. Parking brake: Spring-applied, air-released disc brake on the propeller shaft, designed to hold a loaded machine on a grade up to 18%. When the parking brake is applied, the longitudinal differential is locked. Compressor: Gear-driven by engine. Retarder: Hydraulic, infinitely variable, integral with transmission. Total retarding capability includes transmission retarder and VEB, see graph. Volvo Engine Brake: Standard. Operator selectable application
together with service brakes or when accelerator pedal is released. Always engaged together with retarder. Total retarding capability including transmission retarder and engine brake, VEB, see graph on page 4.



Pumps: Three engine-dependent, variable piston pumps mounted on flywheel power take-offs. One unused power take-off available. Ground-dependent hydraulic pump for supplementary steering mounted on the drop box. Filtration: Through two paper filters with magnetic cores.

Volvo cab, designed for high operator visibilty, ergonomics and comfort. Wide threshold-free door opening and ergonomic instep. Isolation rubber pads to reduce vibrations.Tilt/ telescopic steering wheel. Overhead console for radio and storage. Dash-mounted Operator's Communication System. Storage bins. Standard: ROPS/FOPS tested and approved. (ISO 3471, SAE J1040) /(ISO 3449, SAE J231) standards. Heater and defroster: Filtered fresh air, four speed fan and pressurized cab to maintain a clean operating environment. Multi-level air outlets and separate defroster vents for all windows. Operator's seat: Adjustable air supension operator´s seat with flameproof upholstery. Retractable seat belt. Trainer seat: Standard, with seat belt and back rest.

Hydro-mechanical self-compensating articulated steering for safe and accurate high speed hauling. Fast acting, low effort steering with 3,4 lock-to-lock turns for low speed manuverability. Cylinders: Two double-acting steering cylinders. Supplementary steering: Complies with ISO 5010 at total machine weight. Steering angle: ± 45°




Load and dump brake: With the engine running, the service brakes on bogie axles are applied and transmission shifted to neutral. Body: Hardened and tempered steel body with high impact strength. Cylinders: Two single stage, double-acting.

Diagonal lines represent total resistance (grade % plus rolling resistance %).
Charts based on 0% rolling resistance, standard tires and gearing, unless otherwise stated.
In the retardation chart the diagonal lines represent the "total resistance" as well, which is the grade in % minus the rolling
resistance in %.
A. Find the diagonal line with the appropriate total resistance on the right-hand edge of the chart.
B. Follow the diagonal line downward until it intersects the actual machine weight line, NMW or GMW.
C. Draw a new line horizontally to the left from the point of intersection until the new line intersects the rimpull or retardation
D. Read down for vehicle speed.
