The A/C condenser fan on the Pulsar NX had seen better days. The motor was shot - corroded and tired after 37 years of duty. Unfortunately, like so many parts for this car, a direct replacement doesn't exist anymore.
I grabbed a generic 12V 80W fan motor from Amazon. It was the right spec but predictably didn't match the original mounting pattern on the fan support bracket. No surprise there - when has anything bolted right up to this car?
I designed an adapter bracket to mate the new motor to the existing mounting hardware and printed it in MatterHackers CarbonX - a carbon-fiber-infused nylon. It's rigid, heat-resistant, and more than up to the task of living near a condenser. One of the advantages of having a printer dialed in for engineering materials is that problems like this become an afternoon instead of a dead end.
The old assembly next to the new one tells the whole story. Thirty-seven years of heat on the original versus a fresh motor with a bracket that'll probably outlast the car.
Another discontinued part problem solved with a spool of filament and a couple hours of CAD work. The Pulsar's A/C system is back in business.
