-- Cut off the nozzle on the tube of sealant at the front mark (diameter of nozzle approximately 3 mm).
The sealing compound bead must not be thicker than 2 to 3 mm, otherwise excess sealing compound could enter the oil pan and may block the oil suction pipe strainer. Likewise, it could drip onto the sealing surface of the crankshaft seal.
Before applying the bead of sealant, cover the sealing surface of the seal with a clean rag.
-- Apply silicone sealing compound bead -arrow- as illustrated to clean sealing surface of sealing flange.
-- Install sealing flange immediately and tighten all bolts lightly.
To position sealing flange with sealing ring installed, use guide sleeve T10053/1.
