Lee It is very important and can make for ease of shifting and longevity of input bearing and other clutch and trans components. Just a good practice to check it. There are offset dowls that you install in the block to move the bellhousing. Not just Safir bellhousings but all bellhousings. Here is a link to help you understand the way it is done.Is it crucial to zero runout the SAFIR bell housing? If yes, how does one do that? thanks
Measured both. First measurement is most important! If it's not centered it will move the input shaft around and cause shifting issues and pre-mature failures.Interesting video. But I thought the runout was measured at the face of the bell housing and and how parallel it is to the flywheel. This guy is measuring the inner bore of the bellhousing. Not really following how it applies to the Safir bell. thanks
Joe, Thank you. I would say they are 1/8 to 3/16.What are your panel gaps set at? Those look great!
