#10254 Ford Modular V8 Camshaft Gear Set
Thank you for choosing COMP Cams® products; we are proud to be your manufacturer of choice.
Please read this instruction sheet carefully before beginning installation, and also take a moment to
review the included limited warranty information.
Note: Installation is identical to the Ford factory procedure with the following exceptions:
1. Installation – Rotate the crankshaft until the timing mark is facing the 6 o’clock position,
and the keyway is in the 11 o’clock position, making sure that the timing marks on the
camshaft gears are pointing above the cylinder head. This will put the #1 piston at Top
Dead Center (TDC). Remove the factory camshaft gears, and replace them with your new
COMP Cams® Adjustable Gear Set. Be sure to verify that the adjusters are set to 0º
before reinstalling the timing chains. To install the timing chains, line up the colored
links on the chains with the timing marks on the crank and cam gears, and then install and
release the timing chain tensioners. COMP Cams® strongly recommends that you degree
the left and right cams in order to verify that the chains are installed correctly before
proceeding with any further adjustments. Important: be sure to use the factory cam gear
spacers (Ford PN F3AZ-6265-A). Refer to a factory engine manual for torque specs and
assembly/disassembly procedures. Note: The left hand (driver side) features the cam
sensor pickup. The right hand (passenger side) has two locations for using your
adjusting tool and no cam sensor pickup.
