Burks 22105-C Aluminum Bronze Impeller Washer 0.38 by 1.31 by 0.25 in
This is the aluminum bronze impeller washer Burks lists as part 22105-C at 0.38 by 1.31 by 0.25 in, on G6 and G9 series pumps. It is the bearing surface the impeller fastener tightens against, and it is what keeps that clamping load distributed and consistent.
Washers dish, gall and corrode under the clamping load. A dished washer no longer holds the fastener tight, the impeller works loose on the shaft, and what follows is damage to the impeller bore, the key and sometimes the shaft itself.
Fit it as part of the wider job. The part is listed for G6 and G9 series pumps, at 0.38 by 1.31 by 0.25 in. Whenever the impeller or the seal is off, this is the moment to renew the small items around them rather than to judge them by eye.

Frequently Asked Questions
Q: Does this need replacing every time?
Inspect it and renew it whenever the part it works with is being replaced. It is inexpensive, it is inside the pump, and a second strip-down to fit a small part is an expensive way to learn the lesson.
Q: What happens if it is left out at reassembly?
That depends what it does. A missing load-spreading washer lets the fastener bite into softer material and work loose, while a missing slinger lets escaping liquid run along the shaft into the motor. Neither is worth the risk.
Q: How do I fit it the right way round?
Note the orientation of the old one before it comes off, and follow the Burks assembly sequence. Some of these parts have a chamfer or a dished face that belongs against a specific component.
Q: How do I tell if the old one is worn?
Lay it on a flat surface and look for rocking, which shows it has dished under load. Pitting, a witness mark from a fastener head, or corrosion that has eaten into the face are all reasons to fit a new one.
