Flywheel bolt pattern change
 

Hi everyone and greetings from Finland!

It is possible to change 11" 143 teeth flywheel bolt pattern to same as 10.5" 130 teeth use? Okay, machining new bolt holes should be able to do in the right place. But should I need take into consideration something else?


That question, because here is very poorly on offer these parts, example bellhousings.

Welcome. If you mean the bolts that hold the pressure plate, yes. There are some manufacturers that build flywheels with multiple patterns for different clutches to bolt on.

If you are going to do it go to a good machine shop with the right equipment to index it accurately.
