Identification sources and unresolved matches
The newer Polaris manual H0399500 Rev E applies to PB serial numbers with a manufacture date on or after December 1, 2011. Fluidra's archived 2024 catalog page 352 also lists a newer serial range after PB120111001 or beginning AVEH050100; confirm a complete label against the source rather than inferring a date.
The older catalog page 353 identifies pumps prior to serial M120111001 and shows a threaded-shaft motor. It does not establish fitment for every earlier/keyed-shaft version. A changed motor alone does not identify the pump generation.
GO-KIT87V is NOT recommended automatically: Aladdin's heading says PB4SQ while its model field says PB4-60. Exact pump and kit compatibility need confirmation.
This tool is for part identification, not electrical installation instructions. Use qualified service personnel and the equipment safety manual.

Before you order PB4-60 parts
How do I identify my PB4-60 generation?
Start with the pump's label, serial number and manufacture date, then compare its assembly with the matching manufacturer diagram. A replacement motor label alone does not identify the pump generation.
Can I use this parts diagram for a PB4SQ?
No. PB4SQ is a different model. Choose the PB4SQ option above for identification guidance rather than selecting PB4-60 parts.
Are older and newer PB4-60 parts interchangeable?
Do not assume interchangeability from the shared PB4-60 name. Compare the exact generation, manufacturer part number and assembly notes. Ask Benchmark for help if the label or drawing does not match.
What if the part I need has no purchase link?
Keep the manufacturer number and use the parts lookup below, or contact Benchmark with the pump-label photo and diagram reference. An unlinked reference does not establish current availability.
