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




Dual circuit system with air-hydraulic disc brakes. Comply with ISO 3450 and SAE J1473 at total machine weight. Circuit Division: One circuit 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. Load and dump brake: With the engine running, the service brake on the bogie axles is applied together with the parking brake. Compressor: Gear-driven by engine transmission. Exhaust brake: Standard. Retarder: Hydraulic, integrated in transmission as standard. Infinitely variable with the retarder pedal or full effect appliedvia the service brake pedal. For retarding capability incl. retarder, exhaust brake and engine, 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.

Diagonal lines represent total resistance (grade % plus rolling resistance %).
Charts based on 0% rolling resistance, standard tyres and gearing, unless otherwise stated.
In the retardation chart the diagonal lines represent the "total resistance" as well (here in downhill grades it is
the total extra pushing force), 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 curve.
D. Read down for vehicle speed.
