Clutch Plate Bolt question

[JohninKuranda]

I have a 1928 35A which has a 3 fingered V8 pressure plate with a machined flywheel. I have just replaced the pilot bearing and have started to re-assemble.

Of the six bolts that attach the pressure plate, five tighten as they should. One however just turns. Taking the bolt out, the thread is intact but there are pieces of metals shavings attached.

Of the possibilities, I have thought that this is waste left over from the machining. I would not have thought that a bolt could normally strip metal from the flywheel itself, but it is possible that in the tightening and torquing this has occurred. I have also considered that the hole was not drilled deep enough. I have cleaned out what I can but still I cannot tighten to torque the bolt.

The options as I see it are:

• Just tighten to specs the other five and don't worry about it too much,
• Use thread tape and Thread Lock,
• Tap the hole a tad deeper and use a longer bolt, or
• Something else I haven't thought of as yet!

I guess the question that I have is this. If this was your car, what would you do; preferably something that does not involved taking off the pressure plate itself?

Thanks
