 |
|
I was torquing on my clutch pressure plate to 17 lbs and I snapped a bolt. What size are the bolts that attaches the pressure plate to a 12 volt flywheel ? There are 6 of them.
I was able to turn it through to the other side of the flywheel, and what was left fell out. I would rather know the bolt size before I go to the hardware store as I have been burned with wrong bolts before.
Thanks ! |

| 8X 1.25 The Hardware Store usually has a Sample Nut and Bolt display so people like you and I can just show up with a Bolt and thread it into the display to find out what size it is. |

| I don't have one in front of me, but I would guess the thread portion is around 20mm long. Can you take one of the other Bolt's with you to the Store? |

It was 20mm. They fit great. Thank you for you help. For the record, if someone searches this site. Pressure plate bolt size: M8x1.25x20mm |

According to Volksbolts Air-Cooled clutch bolts are M8x20mm
Std thread which is 1.25pitch.
You need a High Tensile part so go for a 10:9 or 12:9 grade.
Some Type4 engines use an unusual M7 bolt. Volksbolts stock these in 12:9 grade. |
