The Yamaha Crankcase Separating Tool is a specialized heavy-duty puller from the MR (Mechanical Repair) Series. It is designed specifically for disassembling vertically split crankcases on Yamaha motorcycles. This tool is essential for professionals performing deep engine repairs, such as crankshaft replacement, main bearing service, or gearbox overhauls, as it allows for the safe separation of the case halves without prying or hammering.
Product Highlights
Universal Yamaha Fitment: Specifically designed for the bolt patterns found on the Yamaha RX100, RX135, R15, FZ, and MT-15 series.
Non-Destructive Separation: Uses a centered forcing bolt to push against the crankshaft end, safely "lifting" the crankcase half away. This eliminates the risk of cracking the aluminum cases or damaging the gasket surfaces.
CNC Machined Precision: Every component is manufactured to industrial standards, ensuring the M8 and M6 mounting bolts fit accurately into the factory case holes.
High-Torque Durability: Forged from hardened tool steel to handle the high pressure required to break the factory seal and overcome the friction of seated dowel pins.
