7.2 Pump distributor gears (PDG)
The pump distributor gears is directly flanged to the diesel engine and transfers
engine power to the individual hydraulic pumps.
The oil level of the pump distributor gears must indispensably be checked daily. Check
the oil level, before you start the diesel engine! When the diesel engine has been
started, checking of the oil level is no longer possible.
To read the oil level, the machine must be standing on even and level ground and the
engine must have been shut off for at least 5 minutes. When the oil level rises or falls
without evident reason, indispensably call in a customer service mechanic.
The oil level can be read at the inspection glass (2). It must be within the inspection
glass range (in no case above the top edge of the inspection glass!). The inspection
glass is located on the left side of the pump distributor gears.
The gear oil is cooled by its individual oil cooler (see page 330).
