Crankcase by Can-Am

Can-Am UTV / ATV and Side by Side Original Equipment Manufacturer OEM Crankcase & Components - Available at buywitchdoctors.com

Product Specifications: Genuine OEM Can-Am Crankcase, Part # 420686556.

When you are pushing your high-output Rotax engine to its absolute limits through bottomless mud holes, treacherous rock gardens, or high-speed desert whoops, the structural integrity of your engine block is your ultimate defense. Maintain factory performance, absolute internal alignment, and maximum oil containment with premium Can-Am UTV/ATV OEM Crankcase & Components. Engineered specifically to accommodate your vehicle's rotating assembly and oiling system loops, these genuine Original Equipment Manufacturer engine blocks and case halves restore the exact structural rigidity, thermal expansion profiles, and precision tolerances your machine had straight off the assembly line. Do not risk a catastrophic engine failure or an oil-starvation lockup by trusting cheap, poorly machined aftermarket substitutes.

Every genuine Can-Am engine case block, split housing, and internal oil passageway provides unmatched durability and seamless drivetrain integration. These heavy-duty components undergo rigorous metallurgical analysis and stress-load factory testing to ensure they do not crack under massive torque spikes, heavy cargo payloads, or intense trail vibrations. Whether you are building a fresh short block after a thrown connecting rod or refreshing weathered oil seals and dowel pins during a seasonal overhaul, choosing official OEM parts ensures your side-by-side or quad performs flawlessly under the most punishing off-road scenarios.

Why Choose Factory-Direct Can-Am OEM Crankcase Assemblies?

The internal environment of your off-road machine's motor handles intense physical strain. Continuous high-RPM torque, high thermal stress cycles, and sub-zero winter temperatures can easily warp or ruin lower-grade aftermarket metal castings, causing misaligned internal bearings and severe oil leaks. Upgrading or replacing your internal engine core with a genuine factory engine block delivers explicit engineering advantages that protect your powertrain longevity.

• Premium Hardened Aluminum Alloys: Cast and machined from automotive-grade aluminum blocks designed to resist hairline fracturing, thermal distortion, and structural fatigue.
• Precision-Line Bored Bores: Features micro-exact internal diameters for main crankshaft journals and transmission input shafts, preventing dangerous internal gear binding.
• Flawless Oil Passage Routing: Internally engineered channels ensure maximum fluid flow velocity and instant oil pressure response to feed your vital upper valvetrain.
• Perfect Dowel Pin Alignment: Sized precisely to guarantee exact case half mating clearances, completely eliminating the uneven pressure loads that blow oil seals.
• Built-In Accessory Mounting Tabs: Provides factory-threaded bosses that line up exactly with original oil pumps, starter motors, and external frame mounts without modification.

Frequently Asked Questions

Why is an OEM crankcase safer than a budget aftermarket short block assembly?

Original Equipment Manufacturer (OEM) crankcase components are metallurgy-tested and line-bored alongside your factory crankshaft and transmission gears. This guarantees absolute axial alignment under heavy loads. Aftermarket alternatives are often cast using lower-grade aluminum scrap with off-spec clearance dimensions, which can ruin main bearings and cause catastrophic engine lockups within hours of a rebuild.

What are the common warning signs that my crankcase body is failing?

The most immediate signs include persistent oil leaks pooling beneath the engine center line, low engine oil pressure warnings on your speedo gauge, a sweet chemical smell from burning oil on exhaust pipes, or thick structural weeping at the case seams. If you notice structural hairline cracks or stripped mounting holes during a routine engine teardown, the case must be replaced immediately.

Do these replacement case halves come as a matched pair?

Yes, to ensure absolute measurement tolerances and smooth bearing surfaces, factory engine cases are line-bored together at the production facility. Installing mismatched individual case halves is highly discouraged, as minor alignment variances can cause severe internal drag, premature bearing wear, and ultimate powertrain failure.
