Perkins Builder Brothers 140517050 Spin-On Oil Filter, Pack of 1 — Sealing Ring, Fits 100 & 400 Series

The Perkins 140517050 spin‑on oil filter is a genuine replacement designed to protect Perkins engines by trapping contaminants and maintaining correct oil flow and pressure.

Built to the tolerances required by modern Perkins powerplants, this filter helps maintain lubrication and cooling pathways that have become increasingly fine as emissions and engine efficiency standards evolved. It installs like a standard screw‑on cartridge and ships complete with a sealing ring; typical service features include an anti‑drain back valve and a bypass valve to support reliable oil delivery during start‑up and under clogged conditions.

How does this filter protect my engine during operation?

The 140517050 captures particles and wear debris before they circulate through bearings, galleries, and cooling passages, helping maintain oil cleanliness between scheduled services. Its internal media and flow‑friendly design are balanced to reduce resistance while filtering effectively.

• High‑efficiency media removes fine contaminants that can abrade precision components.
• Bypass valve prevents oil starvation if the element becomes blocked.
• Anti‑drain back valve keeps oil in the sump and filter during shutdown for immediate lubrication at start.

Will this part fit my Perkins engine model?

The 140517050 is engineered for compatibility with a wide range of Perkins 100 and 400 Series engines, matching OEM dimensions and sealing requirements for proper fit and function. Always cross‑check part numbers and reference your engine manual for service intervals and installation notes.

• Compatible with selected 100 Series models such as 102.04 and 103.11.
• Fits many 400 Series models including 403A‑15, 403D‑17, and 404F‑22T.
• Cross references: P502016, B1405, LF3874 for quick identification.

What are the physical specifications and installation details?
