Honda FK2/FK8 Crankshaft 13310-RPY-G10

Honda Crankshaft Component part number 13310 RPY G10 is a genuine Honda crankshaft used in Honda inline four engines. Simple job, big responsibility. It turns piston up and down motion into rotation that drives your flywheel and transmission. In the Civic Type R K series turbo layout, this crank rides on the main bearings and carries the rod journals that your connecting rods clamp onto.

You buy this when you want OEM spec, not an aftermarket forged unit and not a mystery used core. Common reasons include bringing factory geometry back after a spun bearing, fixing journal scoring, or replacing a crank that measures out of spec after you mic it. Because it’s an OEM Honda crankshaft FK2 and OEM Honda crankshaft FK8 style part, it keeps the original stroke and journal geometry. No displacement changes, no rotating assembly surprises, just back to baseline.

Honda lists this as a direct replacement and notes the supersession from 13310 RPY G00 to Honda crankshaft 13310-RPY-G10. You’ll see it cataloged for Civic Type R applications and sometimes certain Accord 2.0T listings, so do yourself a favor and confirm with VIN and engine code before you order. We run OEM rotating parts like this on our own cars because nothing ruins a build faster than guessing on core condition.

Installer considerations This isn’t a Saturday afternoon bolt on. You’ll fully tear the engine down to get to the crank and main bearing bed, then you’ll measure main and rod bearing clearances and inspect the block and rod big ends. If you’re here because a bearing failed, fix the cause, not just the symptom. Clean the oiling system like your new crank depends on it, because it does. Fitment varies across models and engine variants, so verify through an OE catalog with your year, trim, and VIN before checkout.
