Boxer flywheel studs

The testing of the TR was put on hold, due to the above project. It seems to run fine, but I do agree with you.....it can use some fine tuning. I bought a spark tester, from OTC......measures the kv needed to start the plug, kv while the plug is firing, and the lenght of time of fire in ms. I need to get two vacuum gauges. I will use the spark tester, to isolate any bad plug firing, then use the new ohm meter to test ohms in the plug wires, connectors, etc. I have 12 new plugs.

I will send some more pictures when I have it assembled on the table, and also when in the car.

Thanks for your help.....it is nice to get one good response vs many varied ones......and these are from people who should know!!!!

I think I told you once, that I will retire in Texas, and work for you!!!!!!HAHA

Sounds like you have all the right tools lined up to dial the TR in.

As soon as I saw the Nuts the whole set-up made sense and the reason the short threads went into the flywheel, Trick Set-Up, and pics really help alot of the time fully understanding things.

Yea you're welcome in Texas anytime..;-). 11 months driving season down here..;-).

The flywheel Bolt Torque Mele was pretty humorous. So Ferrari made more mistakes in 5 books in series, what else is new...haha...itwouldn't surprise me if many mistakes and ommisions were on purpose to trip up the unwary.

I took out my depth gauge and did some calculations: Bottom line; the aligning nut will thread 13.44 mm onto the 33 mm stud. Since the long threaded portion is 15.5 mm, the nut will bottom, when the clutch casting meets the flywheel, and still have 2 mm of thread left.

Interesting, this would NOT work of the stud was placed into the flywheel as original.....long threaded side into the flywheel. The short side is only 12 mm long...1.5 mm too short.

They never told me to reverse the studs.....I just figured it out by myself. Apparently someone HAD to reverse the stud at AP Racing. They did state that these where the original studs.

I wanted to do the measurements above, so that I didn't have to install the 6 studs, and find out later, that this wouldn't work.

I will go over my calculations one more time......just to be sure, prior to final install....I still plan to install the clutch onto the flywheel, on the table first.....JUST in case soemthing else goes wrong.....like finding out that 11 ft-lbs isn't enough to overcome the tension.
