Default 924 016/Y VA 016/Z VB first gear synchro, 1/2/3 gear dog

I’ve just had a small run of first gear synchros and first/second/third gear dog rings made, at the request of a customer, for 924 type 016/Y code VA and 016/Z code VB transmissions. Porsche’s part number for the synchro was 931-302-301-02 (93130230102), and it has been unavailable for many years. The synchro ring has a unique chamfered profile that lets it sit into a channel in the gear without a retaining circlip. We’ve made the synchro with proper molybdenum coating to its friction surface, and a manganese phosphate coating of the rest of its surface to prevent galling of the ring against the gear.

The synchro gear teeth (“dog rings”) have never been available from Porsche or any other source, as far as I am aware. Both parts have been made for us by a well-known supplier of transmission parts for Porsches and other European vehicles.

Because the dog ring is not retained with a circlip (as it is for example in a 911 or 931 G31.01 transmission), it lacks a groove that can be used to pull the old one off the gear: it has to be cut off. I’m happy to offer removal and installation of the dog ring as a service. I can also provide instructions, but caution that it can be a bit of a challenge.

Contact me for pricing. I’ll cross-post this to the 924 forums I’m aware of, and please feel free to pass it along. This is not a profitable venture for me, but I am pleased to help keep everyone’s 924s on the road!
