DATA PLATES

When contacting the dealer concerning your bus, or when ordering stock parts, always quote the chassis type designation and the serial number. In the matter of the engine, gearbox or rear axle, the designations and serial numbers should also be stated.

The chassis type and serial number are stamped on a plate at the very front of the left-hand frame member.
The engine type designation, part number and serial number are stamped on the top of the engine block behind the injection pump.
Type description and serial number of the gearbox:
Voith automatic transmissions: on a plate attached to the upper surface of the gearbox.
ZF and Allison automatic transmissions: on the right-hand side of the gearbox
ZF manual: the type designation and serial number are stamped on a plate fixed on the left side of the gearbox.
The final drive part number, serial number and reduction ratio are stamped on a plate on the right-hand side of rear axle casing.

The plate showing the vehicle's Gross Vehicle Mass (GVM): comes with the chassis

NEW INTERNATIONAL MEASURING SYSTEM

To meet the needs of technicians, and to nationally standardize measurements a system was finally established in 1960 and was given the name SI (System International d'Unites).

The Volvo Corporation has been introducing the SI-units into its new publications since 1972. Up to the time of its exclusive use, the SI-unit will be indicated first followed by the former unit in brackets. The largest new units are:

Output is given kilowatts (kW) instead of horsepower (hp)
100 kW = 135 h.p.

Force is given in Newton (N) instead of kilograms force (kgf).
100 N = 10 kp.

Torque is given in Newtonmetres (Nm) instead of metres-kilograms (m.kg).
100 Nm = 10 kpm.

Speed is given in revs per second (r/s) instead of revs per minute (r/min).
100 r/s = 6,000 r/min.

Pressure (in fluids and gases) is given in kiloPascals (kPa) instead of bars.

To counteract parafin wax deposits and ensure good startability in very cold weather, it is recommended to use the special fuel for winter. Alternatively to counteract parafin wax deposits you can also mix a minimum of 25% kerosene (paraffin oil) and up to 40% maximum. A greater percentage than this will cause wear problems because the lubricating ability of the fuel will be reduced.

The mixture of diesel oil is forbidden by law in some countries. If this is the case with regard to your market, use the additive approved by the authorities.

LUBRICATING SCHEME FOR VOLVO B10M

Intervals

Lubrication^* and level checks: 5,000 km

Oil, grease and filter changes: See respective note after chart.

Notes to lubricating scheme

Note 1	Lubricate the moving parts on the brake valve pedal shaft with some drops of engine oil.
Note 2	Grease with 3 grammes temperature-resistant grease (e.g. SHELL Alvania 2 or SHELL Dolium R or corresponding) every 80,000 km.
Note 3	Grease sparingly with universal grease in lithium base.
Note 4	Fill the lubricator and screw it down so hard that it does not loosen.
Note 5	On buses with electric retarder, four.
Note 6	On buses with electric retarder, four.
Note 7	On buses with electric retarder, one under the retarder.
Note 8	Check that the container is half way full of fluid. Top-up if necessary by referring to Page 64.
Note 9	Change the filter every 80,000 km. When topping-up, use ATF-oil, type DEXRON II.
Note 10	Use ATF-oil.
Note 11	Change the oil every 80,000 km or once a year. Use gear oil SAE 90.
Note 12	The grease in the wheel bearings must only be replaced in connection with work on the bearings or if dirt has got in when the bearings are exposed. Clean the bearings and hub thoroughly and grease in according to the instructions in the Service Manual with a long-life grease for wheel bearings, that is so to say lubricating grease with a lithium-lead base and NLGI N^o. 2 consistency.
Note 13	Check the oil level when filling with fuel. Change the oil and filter every 10,000 km.
Note 14	Check the oil level. Change the oil every 40,000 km or at least once per year.
Note 15	Concerning oil and oil-change intervals, see Pages 64-67.
Note 16	Check the oil level. Change the oil every 40,000 km or at least once per year.

^*) Lubricating interval: 5,000 km if lubricating grease on lithium base with EP-additive and consistency NLGI No. 2, e.g., molybdenum desulphide grease is used. The interval is 2,500 km if, for example, chassis grease is used.
