Assembly instructions

Sealing the oil pan






Only "Drei Bond" silicone type 1209, part No. 000.043.203.73 (30-gram tube) should be used as the surface seal. After application of surface seal (silicone bead), screw together within five minutes.


Application of silicone bead

1. At the processing nozzle, cut off the first metering step.





2. Apply a uniform bead approximately 1.5 mm wide to the cleaned sealing surface of the oil pan.
3. Place the oil pan in the correct position carefully so that the sealing bead is not damaged. Screw two studs or centering pins into the corners of the crankcase housing halves as centering aids.
