PROX Crankshaft Oil Seal 17x35x7mm (manufacturer part number: 41.2-17067) — an essential wear part for sealing the engine crankcase. Made in the USA, this PROX oil seal is designed to replace worn crankshaft seals on motocross bikes and small displacement machines. It features the exact dimensions of 17 x 35 x 7 mm for a clean and precise restoration.
The oil seal ensures sealing between the crankshaft and the crankcase to limit oil leaks and maintain engine lubrication. Ideal during a service or restoration after engine disassembly, it replaces the original seal when it shows signs of wear, cracking, or leaking.
Always check the dimensions before installation and the condition of the surfaces on the crankshaft and crankcase to ensure proper fitting. Compatible with several lightweight models: among common applications are the YAMAHA PW 50 (2024, 2025, 2026) — verify compatibility with your machine before ordering.
