Outer crank sprocket 17 tooth

FEULING machined steel, stock replacement roller chain drive sprockets fit 17-25 M8 and 07-17 Twin Cam engines as direct replacements. Also used on early 99-06 engines when converting from spring tensioners to the hydraulic cam chain tensioners using the late style roller chain.

FEULING crank sprockets are designed with a tighter tolerance on the ID for better fit to the pinionshaft which aids in eliminating cam timing variance due to poor crank sprocket fit. Our testing has shown as much as 4 degree timing variance with the loose fit factory sprockets.

Due to the tighter fit, we recommend to complete the camchain alignment using the factory pinion sprocket, then install our #1091 sprocket and double check the alignment. This will save you from having to use a puller on our sprocket multiple times while adjusting the cam chain alignment.
