ALL BALLS Crankshaft Oil Seal Kit (manufacturer ref. 24-2027): a kit designed to restore the sealing of the crankcase during an engine overhaul or after a crankcase replacement. Specifically designed for the motocross universe, this oil seal kit allows for the replacement of wear parts that ensure protection against oil leaks around the crankshaft.
The seals offered by ALL BALLS meet the same specifications and dimensions as the original equipment, making installation easier and helping to achieve a sealing performance that is true to the original. The kit is supplied in pairs to work on both sides of the crankshaft.
Ideal for routine maintenance operations or restoration after disassembly, this kit is aimed at motorcyclists and mechanics looking for a simple and reliable solution for engine sealing. Used on many motocross models — examples: KTM 150 SX (2025), HUSQVARNA TC 125 (2025), GAS GAS MC 125 (2022) — this kit is one of the essentials to keep in stock during a crankshaft overhaul.
