It is designed for a 1-3/4 SAE C-keyed connection.

Got a Permco 257 pump and need to know if this gear/shaft set matches up with the 1-3/4 SAE C-keyed configuration mine came with originally.

For a Permco 257 series pump with a 1-3/4 SAE C-keyed shaft, this is the correct gear and shaft set. The SKU 024-00842-17 is the Permco-supplied replacement set built specifically for that shaft size and keyway spec, so it should drop right into your existing 257 housing without modification.

i keep seeing “SAE C-keyed” in the name, what does that tell me about this set?

Question by: Dustin B on Sep 8, 2025, 4:16 PM

“SAE C-keyed” is the drive style and mounting designation called out for the set, and “1-3/4” is the size noted right in the product name. It is basically identifying the configuration so you can match it to the same SAE C keyed setup you are replacing or building around.
