maXpeedingrods chainsaw crankcase splitter tool for Stihl & Husqvarna — hardened steel, tapered blade

maXpeedingrods crankcase splitter is a purpose-built tool for separating the two halves of chainsaw and small-engine crankcases to access the crankshaft and internal components safely and accurately.

If you service Stihl or Husqvarna chainsaws or perform rebuilds on small two-stroke engines, having a reliable crankcase splitter speeds work and reduces the risk of damaging mating surfaces. This single-piece tool is shaped to push apart crankcase shells after fasteners are removed, and it replaces several OEM part numbers used across common models. It’s designed for professional mechanics, backyard technicians and anyone who regularly repairs or restores chainsaws.

Which models and engines does this splitter work with?

The maXpeedingrods splitter is listed to fit many popular Stihl and Husqvarna chainsaw models and similar small engines. Check model compatibility against your service manual before use; while it fits a broad range, certain rare or modified housings may need an alternative tool or light modification to this splitter.

• Stihl models covered: 026, 036, 038, 044, 046, 064, 065, 066 and MS260–MS660 series.
• Husqvarna models covered: 51, 55, 61, 140B, 141B, 250 series and many 200–400 series saws.
• Replaces OEM numbers: 502 51 61-01 and 502516101 where applicable.

How do I use the crankcase splitter safely and effectively?

After removing all fasteners and separating accessory components, position the splitter between the crankcase halves and apply steady, even force to pry them apart. Use controlled taps with a soft-faced hammer if needed; avoid twisting or levering at extreme angles to prevent cracking the mating surfaces.

• Prep: drain fluids, remove bar, chain, ignition and carburetor components first.
• Placement: seat the tool in the factory joint or designated notch for even pressure.
• Action: tap gradually with a rubber mallet; alternate sides for uniform separation.
• Aftercare: clean mating surfaces and inspect for damage before reassembly.

What materials and construction should I expect from this tool?

This splitter is machined from durable steel to resist bending and edge deformation during repeated use. The profile and thickness are optimized to fit common crankcase seams and transfer force without concentrating stress in a single point.

• Material: hardened steel construction for longevity.
• Design: tapered blade geometry to enter the joint without gouging.
• Finish: corrosion-resistant coating to withstand workshop environments.

Will this tool need modification to work on my engine?

Most users will find it fits the listed Stihl and Husqvarna models out of the box, but some engines with aftermarket cases or unusual casting features may require light modification. Modifications are usually limited to minor reshaping of the blade edge or gentle filing to adapt to a particular joint.

• Typical: direct fit for many stock model crankcases.
• Occasional: slight grinding or filing for nonstandard housings.
• Not suitable: extremely thin or brittle casings that risk cracking under force.

Who is this for: The maXpeedingrods crankcase splitter is intended for chain-saw technicians, small-engine mechanics, and experienced DIYers who service Stihl and Husqvarna saws or similar two-stroke engines. It’s a practical addition to a maintenance toolbox for anyone who disassembles crankcases regularly, offering a cost-effective, sturdy solution for safe separation of crankcase halves.
