Crankcase Splitter and Installer Tool Kit - 15pc Complete Set

In this review of the 15 piece crankcase splitter and installer tool kit the bottom line is simple: it is a practical, all-in-one solution for hobbyists and home mechanics who work on motorcycle, dirt bike and ATV crankcases. The kit's biggest advantage is that it combines a crankcase splitter, crankshaft installer and multiple adapters into a single pack so routine disassembly and reassembly becomes far less fiddly. For anyone who wants a dedicated set that covers most 2-stroke and 4-stroke crankcases, this kit saves time and reduces the chance of damaging case halves during service.

Key Features

• 15pc Complete Set: Includes a crankcase splitter, crankshaft installer, three M6 and M8 bolts, two steel rods, three crankshaft adapters and M10 and M12 screws to handle a broad range of jobs.
• Adjustable 3-Arm Splitter: The splitter has 360 degree adjustable arms to match different bolt patterns and to gently separate crankcase halves without prying on internal parts.
• Secure Installation: The crankshaft installer uses supplied M10 and M12 screws with adapters so the crank can be aligned and pulled into the case cleanly during reassembly.
• Universal Compatibility: Works with most motorcycle, dirt bike and ATV 2-stroke and 4-stroke crankcases, making it a flexible choice for multi-vehicle garages.
• Durable Materials: Machined from structural-grade AISI 1045 steel and chrome-plated with blackening for corrosion resistance and improved strength.

Who It's For

The kit is best suited to DIY mechanics, weekend wrenchers and small shops that perform regular engine work on motorcycles, ATVs and dirt bikes and need a compact set that covers both splitting and installing crank assemblies. It is especially useful when a vehicle does not require highly specialized pullers and the goal is a reliable, repeatable procedure.

Those who should look elsewhere include owners of the excluded models or technicians who need heavy industrial-grade splitters for high-volume professional service where repeated extreme loads are expected; a few customers reported weld failures under heavy strain, so this should be considered for very frequent, high-stress commercial use.

Pros & Cons

Pros

• Comprehensive 15pc kit reduces trips to multiple suppliers and covers both splitting and installing tasks.
• Adjustable three-arm design adapts to many bolt patterns and helps protect case surfaces during separation.
• Solid material choice of AISI 1045 steel with chrome plating improves longevity and corrosion resistance.
• Includes multiple adapters and screws for a secure fit on a range of crankshafts.

Cons

• Some users reported splitter welds failing under heavy loads, so the tool may not be ideal for constant commercial use.
• Not compatible with certain models such as the YMH Raptor 660, Kawasaki Tecate 250 and KTM 125/144/150, so check fitment before purchase.

Our Verdict

The 15pc crankcase splitter and installer tool kit is a practical value for the DIY mechanic or small shop that needs a single kit for both removing and reinstalling crank assemblies. It covers a wide range of crankcases with useful adapters and durable steel construction, but professionals who expect repeated extreme loads should be aware of mixed reports about weld strength and consider a heavier-duty unit for continuous commercial use.
