Fitting
– Lubricate bearing points of balance shaft -arrows- with engine
oil.
– Install balance shaft (inlet side) and tighten bolt -2-.
– Renew O-ring -1- and lubricate with engine oil.
– Lubricate bearing mounting with engine oil and install; dowel
pin -arrow- for bearing mounting must engage in bore in cyl‐
inder block.
Note
Always renew idler gear. Otherwise, the play between the gear
♦
teeth is not ensured, which causes the engine to become
damaged.
The new idler gear has a special lubricant coating which wears
♦
off after a short running period and thus automatically creates
the specified backlash.
– Mark faces of gear teeth of idler gear with paint marker
-arrow-.
– Insert idler gear; marking on balance shaft must be positioned
between markings on faces of gear teeth.
