4.0 with T5 - issues with thinner flywheel
I've read a few things about the 4.0 flywheel being 1/4" thinner than a 258 flywheel, which could cause issues with clutch disengagement (clutch fork running out of room, along with the throwout bearing being close to coming off the fork because of the increased throw). I know Skerr went through an ordeal and had to drill, tap, and install an adjustable pivot (and weld trusses to strengthen that area around it).
With all of the 4.0 swaps that have been done, I haven't seen much published about these issues when used with the T5, T4, T176, etc. Does this commonly cause an issue with a 4.0 swap?
I'm trying to avoid any issues by making the necessary modifications before I put everything in - cuz once I do, I will not be taking it back out anytime soon (hopefully!)
So my question is what modifications, if any, do I need to do? The pivot mod like Skerr (if so, use a pivot from what vehicle?)? I've seen the adjustable throwout bearing that Novak sells, which would easily solve the issue. Problem is, they are still in production.
Not sure what I need to do for this.
