While I was away, my husband decided to replace the impellor. For some reason he also took the propellor off too along with the gears and the shaft. Two bearings fell out one looks like a small hotdog about 1.5 inches long, the other is bigger around with flat ends (like a pill). I put the "hotdog" back in the end of the shaft. But cant figure out where the "pill" goes. Any ideas? <br />Thanks.
