is this the gear/shaft set for a Permco 257 pump with the SAE C-keyed shaft configuration?

Question by: Todd M on Jan 19, 2026, 10:48 AM

For a Permco 257-series pump requiring an SAE C-keyed shaft, this is the correct gear and shaft set to match that configuration. The part number 024-00842-10 corresponds to the Set 1 designation, so as long as your pump calls for Set 1 specs on the SAE C mount, this is what you need for that replacement.
