My old air / vacuum pump failed on the RV-9A O-320. I have replaced it but now have my old pump in hand. Overhaul kits are available from ACS for about $100. I would like to rebuild it and keep it around for when I need another.
Has anyone rebuilt their own air pump? It it relatively straightforward? Would you do it again? Do I need any special equipment?
