PROX Crankshaft Oil Seal 17x35x7mm (manufacturer's ref: 41.2-17067) — an essential wear part for sealing the engine casing. Made in the USA, this PROX oil seal is designed to replace worn crankshaft seals on motocross 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 casing to limit oil leaks and preserve 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 casing to ensure correct fitting. Compatible with several lightweight models: among the common applications are the YAMAHA PW 50 (2024, 2025, 2026) — check compatibility with your machine before ordering.
