PROX Crankshaft Oil Seal 25x35x7 mm — Manufacturer part number: 41.6-253570
Sold individually, this PROX oil seal is intended for replacing the crankshaft side sealing ring. Designed to ensure the sealing of the engine bearing when properly installed, it limits oil leaks between the crankcase and the primary shaft. A simple and precise replacement part, essential during engine intervention or wear revision.
This seal is suitable for many engine displacements, particularly the common 300 cc engines in enduro and cross. Examples of compatible motorcycles: KTM 300 EXC TPI SIX DAYS (2022), HUSQVARNA TE 300 I (2022), GAS GAS EC 300 (2022). Replace the worn seal as soon as oil traces appear or after disassembling the crankshaft to ensure a clean reassembly and proper sealing.
Workshop advice: respect the mounting direction and check the condition of the half-shaft and housing before installation. If in doubt, entrust the operation to a professional to avoid any engine damage.
