Tip: If you look closely at the yellow speed washer, you’ll notice one face is flat, and the other
has a shoulder (ridge) on it. The shoulder is designed to fit around the washers and the pitch
bushings. If you find the oarlock is hard to turn, check to see if two of these shoulders are
sitting against each other. If they are, you can move the speed washer adjacent to a regular
washer or bushing to free it up. If you find that an oarlock has a bit too much vertical play,
then moving the speed washers so the shoulder sits against the flat of another speed washer
will tighten it up a bit. If it is still loose you can have the shoulders facing each other.
