It's a knock off brideport...elevation pinion gear for the knee is out of it. I want to know how to put it back in. It is being delivered in a week so I can send pictures then. Definitely appreciate any help. Thank you

around the knee crank, there is a pattern of 4 bolts.
remove these bolts and the cover they hold and out will come the shaft to which the gear (should be) attached.
reverse process to install gear.
suggest you check the mating gear and replace as needed.
block knee with cribbing to hold in place since you will probably have to manually turn the knee screw DOWN to get the gear(s) in / out and don't want the knee dropping on you during the process.
