I am trying to bring an old AQ140 / AQ 270 combo back to life. When I took the dipstick out of the top of the 270 drive it was way too short. About 3 inches long. If this stick broke off somehow inside the housing where would the other piece end up? I don't want to just replace the stick if there is a chunk of the old one floating around in a gear case somewhere. Right now I am trying to verify if this drive is worth putting money into or if it needs to be replaced. This drive train has not been used since 2006. Everything shifts and spins as expected but I have not started the engine yet.
