M-6316-C351 Crankshaft Check Direction Piece
The M-6316-C351 crankshaft damper has a bolt in counterweight to grasp the 28.2 oz.-in. craze required for outwardly balanced 302 engines produced before to 1981 and all externally balanced 289 and 351 V-8s. For internally balanced engines.
INSTALLATION INSTRUCTIONS:
Step 1: Engine must be completely cold.
Step 2: Mislay h2o pump. Stagger engine by hand until timing pointer indicates 0° TDC.
Step 3: Remove strange check delicately using the puller or removal tool.
Step 4: A 289, 302, 351 engine family has used multiform different timing pointer locations. Most applications will have the timing pointer at a 10 o’clock, 11 o’clock or 2 o’clock pointers. A Ford Racing damper has dual sets of timing outlines for possibly 11 o’clock or 2 o’clock positions; 10 o’clock timing pointers should be transposed with an F1TZ-6023-A. With a crankshaft keyway at the 12 o’clock onallsides, a #1 piston is at TDC. In this onallsides, a timing pointer should indicate to asingle of a 0° outlines upon a check. For a discerning check before to designation, review a timing outlines on the original damper with the marks upon the Ford Racing damper to establish if one of these is the scold timing marks for your application. If it looks like the pointer will not line up with either 0° line, call the Ford Racing Performance Tools Tech “Hot Line.”
Step 5: After you have identified which set of timing outlines are correct for your engine, highlight the grade mark for your initial timing environment with paint or douse pencil (white or yellow have been easiest to see) for future timing location marker.
Step 6: Inspect a crankshaft post to safeguard there have been no burrs or rust. If required, polish with Scotchbrite or really fine emery paper.
Step 7: Measure a crank muzzle OD as well as a Check ID (at a minimum territory. Correct measurements with both tools during a same temp are essential. Subtract the damper ID from a crank muzzle OD to establish the interference fit. Recommended fit is .0002? to .0012?. If the interference is excessive Aswell tight) have the check heart ID honed to bring the fit to spec. Most automotive appurtenance shops.
