Voith DIWA.5 Transmission Technical Manual (2007) – 824.5 854.5 864.5 PDF

Description

Voith DIWA.5 Transmission Technical Manual (2007) – Complete Reference for the 824.5, 854.5 and 864.5

This Voith DIWA.5 Transmission Technical Manual is the full 2007 factory reference for the Voith DIWA.5 automatic transmission range built for city and suburban buses. Issued by Voith Turbo GmbH & Co. KG (document 150.00368910_ENX), it covers the 824.5, 854.5 and 864.5 transmission generations in complete technical depth – configuration, function, control logic, technical limits and installation. If you support, specify, or maintain DIWA.5-equipped buses, this manual is the single document that explains how the whole system is built and how it behaves.

IMAGES PREVIEW

Together, these chapters give a technician or installer everything needed to correctly configure, mount, wire and understand a DIWA.5 transmission from the moment it arrives on the shop floor to full commissioning on the vehicle.

Technical Data You Can Use Immediately

The Voith DIWA.5 Technical Manual tabulates hard numbers for every model in the range: input power up to 290 kW, input torque figures from 650 Nm up to 1750 Nm depending on control mode, operating pressures of 8.5 and 9.5 bar, transmission dry weights of 295-305 kg, oil quantities of 25-28 litres, axle ratio ranges of 4.5-7.5, and full cooling-system parameters including thermostat, flow rate, and coolant chemistry limits. Braking torque values for stages B1-B3, allowed input speeds for converter brake engagement, and cardan shaft angle and length limits are all laid out by dataset (T0R0, T0R2, T2R0, T2R2). The type-plate and model-code diagrams let you decode any DIWA.5 nameplate on sight – reading off the differential ratio, pump/turbine diameters, angle drive code, and operating pressure straight from the stamped model number.

The DIWA.5 control unit section is equally detailed, walking through CAN communication, the early warning system, event memory, forced downshifting during braking, retarder integration, and the BASP shift program logic that governs how the transmission actually shifts on the road.

Why Technicians and Fleet Engineers Need the DIWA.5 Technical Manual

This Voith DIWA.5 Transmission Technical Manual gives you the ability to correctly specify, install, wire and diagnose a DIWA.5 automatic transmission without guessing at torque limits, pressure settings, or cable routing. Getting these values wrong on a bus transmission risks premature wear, control faults, or drivetrain damage – this manual puts the correct Voith-published figures directly in your hands. Because it’s delivered as an instant PDF download, you can have the complete Voith DIWA.5 Transmission Technical Manual open on a laptop, tablet, or phone in the shop within minutes of purchase – no shipping wait, no printed manual to misplace, and it prints cleanly on any home or shop printer if you prefer paper in hand while you work.
