Ford Racing Crankshaft Damper INSTRUCTION SHEET

INSTALLATION INSTRUCTIONS:

Step 1: Engine must be completely cold. Drain coolant.

Step 2: Remove water pump. The M-6316-D302 damper is larger in diameter than most production dampers and may interfere with the water pump during damper installation. Rotate engine by hand
until timing pointer indicates 0 degrees TDC.

Step 3: Remove original damper carefully using a puller or removal tool.

Step 4: The 289, 302, 351W engine family has used several different timing pointer locations. Most
applications will have a timing pointer at the 10 o’clock, 11 o’clock or 2 o’clock position. The Ford
Racing damper has two sets of timing marks for either 11 o’clock or 2 o’clock positions; 10 o’clock
timing pointers should be replaced with an F1TZ-6023-A. With the crankshaft keyway at the 12
o’clock position, the #1 piston is at TDC. In this position, the timing pointer should point to one of
the 0° marks on the damper. For a quick check prior to installation, compare the timing marks on
the original damper with the marks on the Ford Racing damper to determine if one of these is the
correct timing mark for your application. If it looks like the pointer will not line up with either 0° line,
see Step 17.

Step 5: After you have identified which set of timing marks are correct for your engine, highlight the degree
mark for your initial timing setting with paint or grease pencil (white or yellow are easiest to see) for
future timing location identification.

Step 6: Inspect the crankshaft post to ensure there are no burrs or rust. If required, polish with a very fine
emery cloth. Check leading edge of crank for appropriate chamfer. If required, chamfer as
necessary using a file and emery cloth.

Step 7: Measure the crank snout OD and the Damper ID (at the minimum section).
