Work description
Tools
The work description is general and applies to all versions of the manual gearbox.
The work description is based on a manual gearbox with retarder. There are minor
differences in working methods between the different versions depending on whether
the gearbox is combined with:
• Torque converter
• All-wheel drive
• Opticruise
• Power take-off EK 630/640
• or if the gearbox does not have a retarder
The extent to which any extra equipment such as power take-off, torsion damper, etc.
have to be removed, has to be determined from case to case.
