Oil change diagram of Voith retarder

Apr 01, 2019

All Voith retarders must first unscrew the oil filler plug when draining the oil. At this time, the oil filler port acts as a vent hole, which can quickly drain the waste oil. After the oil is drained, tighten the oil drain plug. Slowly add a proper amount of engine oil to the fuel filler port, and tighten the fuel filler plug. If you accidentally add too much oil, you can only repeat the oil drain action and refill (except for 133-2).

Tools required: Oiling screw plug and oil drain screw plug-22mm outer hexagonal socket; dipstick screw plug-12mm inner hexagonal wrench

Oiling capacity: 6 liters for maintenance and oil change; if the radiator is replaced, 7.5-9 liters according to the size of the radiator

Note: The oil-water discharge screw plug should be disassembled and inspected when discharging the oil. Waste water and waste oil will be discharged; if you accidentally add more oil when refueling, you can unscrew the oil level screw plug to release the excess oil.
