Volkswagen Golf / Golf GTI / Golf Variant. Manual - part 659

– Lubricate the balance shaft mountings -arrows- with engine

oil.

– Install the intake side balance shaft and tighten the bolt -2-.

– Replace the O-ring -1- and coat with engine oil.
– Coat the mounting pin with engine oil and insert it. The align‐

ment pin -arrow- for the mounting pin must engage in the hole

in the cylinder block.

Note

♦

Always replace the intermediate sprocket. Otherwise the

backlash will not adjust itself and it could result in engine dam‐

age.

♦

The new intermediate sprocket has an anti-friction coating that

wears off after a short period of use, which automatically ad‐

justs the backlash.

– Mark the tooth face on the intermediate sprocket -arrows-.
– Install the intermediate sprocket; the marking on the balance

shaft must be between the markings on the tooth faces.

– Tighten the bolt -1- for the intermediate sprocket: tightening

sequence. Refer to

⇒ Fig. ““Intermediate Sprocket Tightening Sequence”“ ,

page 118

 .

– Check the markings on the intermediate sprocket/balance

shaft -arrow-.
