• Air cleaner cover

Note:

If the cover screws are loosened or tightened with a power tool the lower part of the thread can be damaged. Therefore the use of a power tool is only permissible when:

• ◆ The power tool speed is max. 200 rpm
• ◆ The tightening torque is set to max. 3 Nm

• Filter element
• Air cleaner lower part

• Gasket
• ◆ Renew if damaged
• Crankcase breather hose
• Warm air intake
• Air intake housing with regulating flap
• ◆ Check intake air preheating => Page 24-74

→ Fig. 1     Resistance graph

The diagram is valid for coolant temperature sender (G62) and intake air sender (G42).

The diagram is divided into two temperature ranges:

•      A -     From 0...50 °C
•      B -     From 50...105 °C

Examples:

• ◆ 30 °C is in range A and corresponds to a resistance of 1.5...2.0 kω
• ◆ 80 °C is in range B and corresponds to a resistance of 275...375 ω

→ Fig. 2     Removing air cleaner

• ‒ Loosen air cleaner at securing screws marked by arrows.

Note:

If the securing screws are loosened or tightened with a power tool the thread in the intake pipe can be damaged. Therefore the use of a power tool is only permissible when:
