13- Mechanical drive gear unit – 2550
13.1  General
This type of truck is equipped with a drive gear unit mounted on the 
chassis with 6 bolts.
The transmission is integrated with the motor, brakes, and sensor 
measuring speed, steering wheel direction and direction of travel, as a 
complete drive assembly. The drive assembly is equipped with 360° 
steering.
The transmission in this truck is a two-stage angle transmission with 
conical roller bearings on the drive shaft and pinion. The bearings are 
pre-tensioned approximately 5/100ths of a mm to minimise the risk of 
play in the bearings.
This service instruction includes directions for dismantling and assem-
bling the drive transmission, filling and changing the oil and measures 
in the event of leakage. A complete renovation of the drive transmission 
is so extensive that specially trained personnel must do this in the work
-
shop.
