Honda B Series VTEC/C30A/C32B Cam Gear Bolt 90031-PV0-305

Honda B Series VTEC/C30A/C32B/L15A Cam Gear Bolt - 90031-PV0-305

Doing a timing belt job on your B series VTEC, NSX, or L15 Fit and you need cam gear bolts? This is the OEM bolt that secures your cam gear to your camshaft. Part number 90031-PV0-305. It threads into the end of your cam and clamps the cam gear down tight. Sure, you could probably find some random bolt in your toolbox that threads in and kinda works. But is it the right length? Right thread pitch? Right grade? Wrong bolt means your cam gear's not secured properly and your valve timing can slip. Don't guess. Use the OEM bolt and know your cam gears are torqued down right.

Here's Why the Right Bolt Matters

Cam gear bolts hold your cam gears to your camshafts. If the bolt's too short, you don't get enough thread engagement and it can back out. If it's too long, it bottoms out before the cam gear's clamped tight. Wrong thread pitch and you're stripping threads in your aluminum camshaft. Wrong grade steel and the bolt can stretch or break under load. Your cam gear slips even one tooth and your valve timing's off. Your engine runs like crap or it doesn't run at all. If the gear slips multiple teeth, your valves hit your pistons and you're rebuilding your head. The OEM bolt's the right length, right pitch, right grade. It's designed specifically for this application. Don't risk bent valves on a mystery bolt from the parts bin.

Sold Individually, All Engines Need Two

This bolt's sold individually. B18C1, B18C5, B16A2 engines all have dual overhead cams (intake and exhaust), so you need two bolts per engine. The C30Aand C32B found in the NSX will require 4 bolts and the L15 found in the Fit and Insight uses 1 bolt. 

Replace Them During Timing Belt Jobs

When you're doing a timing belt replacement, head gasket, or any job where you're pulling your cam gears, it's smart to replace these bolts. They're cheap and they're critical for keeping your valve timing correct. You're already buying a timing belt, tensioner, and water pump. Throw in fresh cam gear bolts and know everything's right. Don't reuse a bolt that's been torqued down for 100k+ miles and hope it's still good. Fresh bolts are cheap insurance on an expensive timing job.
