After making a small cut so the trim piece can seat properly. The bulge along the top curve will get fixed later.

And then after about an hour of pushing and prying and squeezing, I had the left side done.

That was a pretty easy install, with some care to trim the ends at the correct angle.

I decided to get back to some engine work, hoping to have my heads by the end of next week.
Today was ring gap day, so I opened the set of P&C from Aircooled.net, with 96 mm JE pistons and biral cylinders. I had them balance the pistons and pins. Attached thumbnail(s)

I measured the ring gaps in the cylinders. All were within spec.

I would bet Bob understands "fit" very well. I am a bit envious of his work, but still working full time.
Keep up the good work Bob and thanks for posting |

Thanks, guys. Sure is more fun without worrying about real work. Though I am supposed to be supervising some student research. And getting my own done. And writing a research paper or two. And writing a new edition of a college text.
But working on the 914 is always more fun. |

Another diversion today: I got out the trunk lock. This is a used replacement, since the car came with a non-functional electric lock release.

But that means re-keying the lock to match the rest of the car. Here is the lock partly disassembled.

And the cylinder with all the original pins. I did not get a shot of the misalignment with the key installed, but most pins were too high or low.

After some pin swapping, and just a bit of filing, I got the alignment looking good.

And then got the lock itself back together. (Yes, that is a vintage key ring from the shop of my old friend Ed Mayo, in Texas. It came with the car.)

The new rubber gasket from 914Rubber needed one notch enlarged.
