Orion Motor Tech Crankcase Splitter and Installer Kit — 15‑Piece 360° Adjustable Arms, AISI 1045 Chrome

This professional-grade kit combines a crankcase splitter, crankshaft installer, adapters, bolts and steel rods in one set to remove and fit crank assemblies without damaging case halves or bearings. Constructed from AISI 1045 steel with chrome plating and blackened finish, the tool is built for repeated garage and shop use. It supports a wide range of motorcycles, dirt bikes and ATVs while excluding a few specific models.

How does the adjustable 360° arm design improve crankcase separation?

The three pivoting arms rotate around the central hub to match different bolt patterns and pulling points, so you can apply even, controlled force across the crank assembly. That reduces twisting or uneven pressure that can crack or score case surfaces.

• Three arms with full rotation for custom bolt alignment
• Evenly distributes extraction force to avoid case distortion
• Works with multiple bolt layouts found on two- and four-stroke crankcases

What components are included and how do they help reinstall a crank?

The kit contains a crankshaft installer plus M10 and M12 screws, multiple crankshaft adapters, steel rods and additional bolts to ensure a precise, centered press of the crank into the case. Using the correct adapter and screw size eliminates hammering and reduces risk to bearings and seals.

• Crankcase splitter and crankshaft installer for removal and fitment
• Three crankshaft adapters for common journal sizes
• M6/M8 bolts and M10/M12 screws for secure threading and controlled torque
• Two steel rods to support alignment during installation

Which engines and vehicles are compatible with this crank puller installer kit?

The set is designed to work with the majority of two- and four-stroke motorcycle and ATV crankcases, including many dirt bikes and off‑road machines. Note the exclusions: it is not compatible with YMH Raptor 660, Kawasaki Tecate 250, or KTM 125/144/150 models.

• Fits most 2‑stroke and 4‑stroke motorcycle and ATV crankcases
• Ideal for dirt bikes and general motorcycle maintenance
• Check exclusions (YMH Raptor 660, Kawasaki Tecate 250, KTM 125/144/150)

How durable and serviceable is the toolset for repeated workshop use?

Forged from structural-grade AISI 1045 steel, chrome-plated and blackened for corrosion resistance, the components are sized and finished for longevity under repeated load. Replaceable bolts and adapters mean you can swap worn parts instead of discarding the whole kit.

• AISI 1045 steel construction for strength under torque
• Chrome plating and blackened finish reduce rust and wear
• Modular pieces (adapters, screws, rods) are replaceable
