I found 11 of these small bolts while going thru extra parts, one of them had the small sleeve (red arrow) over it. There is a prominent dimple in the top of the hex head. Anyone recognize these bolts ?

QUOTE(ctc911ctc @ Jul 12 2022, 07:38 PM)  Engine Bay torsion Rod Bolts? I think the bolts there, are built in to the chassis, and sticking up so that you just slip the retaining brackets over and add the nut. Other ideas? . |

They sort of look like ring gear bolts. The ones that lock with a tab and hold the ring gear on the diff.

Remind me of flywheel bolts the one "cap" bolt looks like a plug to something? Don't think they are 914 related.

I agree with the ring gear bolts.

You know, IMHO, you have to do a "hats off" to the guy who designed & tested these things. Were these developed with FEA software?

QUOTE(windforfun @ Jul 13 2022, 08:05 PM) Were these developed with FEA software? I think 1st commercially available NASTRAN software (early FEA) wasn't available until 1969. Highly doubt it's use here since 914 and/or 901 transmission designs were already well established prior to 1969. |
