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 (see Workshop Equipment Manual, No. 165). Lay removed engine parts on a clean base and cover them without fail. Even the smallest particles of dirt can block up oil bores.
- 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.

Information:
This mounting specification applies to all 996 engines except for the Turbo and GT3. Earlier information is no longer valid.
