Connecting Rod, Engine

Mounting specification for connecting-rod bolts

Caution
When working on the engine, absolute cleanliness is essential. An engine cover should be used on the engine assembly support. Lay removed engine parts on a clean base and cover them without fail. Even the smallest particles of dirt can block up oil bores.

Caution
Connecting-rod bolts must not be re-used after unscrewing because they could cause damage to the engine.
- New connecting-rod bolts must not be screwed on more than 4 times during mounting.
