 Left-handed threads on a 911 Which bolt or fastener has left-handed threads as to conventional right-handed threads on a 911 3.2? Thank you for the reply, Calilber | 
| 
 My 84 Carrera doesn't have any LH thread bolts as far as I know. | 
| 
 If anything, your main pulley. |

 No, the crankshaft pulley bolt is standard (RH) thread. Yes, tie rods – on pre-Turbo tie rods. Throttle linkage at the engine has both L & R threads. Another is on the fitting at the oil tank on the optional front cooler, 1973 only. Best, Grady |

 I believe the air pump pulley was left-hand thread on a 79. |

 Can you see why Grady won a lot of Porsche tech quizes? |

 Yeah... a wealth of info and good to know info too! I was certain my main pulley was LH, but I stand corrected as I only took it off once. |
