TIMING CHAIN

Note. The crankshaft timing mark (3) or (5) can be in one of two locations depending on whether the engine is early production (5), late production (3) or assembled with service parts (3). In all cases the keyway (2) will always be in the 9:00 position, in line with the ladder frame mounting surface (1) when the engine is at TDC.

  1. Verify that the engine is still set to TDC.
  2. Align camshaft timing marks (3) so they are facing each other and in line with the cylinder head cover sealing surface (2).
  3. Install timing chain so plated (or marked) links on chain align with timing marks on camshaft sprockets (1).
  4. Align timing mark on the crankshaft sprocket (3) or (5) with the plated (or marked) link (4) on the timing chain. Position chain so slack will be on the tensioner side. NOTE: Keep the slack in the timing chain on the tensioner side.
  5. Install the timing chain tensioner (5). Refer to «TENSIONER, Engine Timing , Installation»(ref-462490-S18212064152012040500000) . Rotate the crankshaft CLOCKWISE two complete revolutions until the crankshaft is repositioned at the TDC position with the key way at the 9 o'clock position.
  6. Verify that the camshafts timing marks (3) are in the proper position and in line with the cylinder head cover sealing surface. If the marks do not line up, the timing chain is not correctly installed.
  7. Install front timing chain cover. Refer to «COVER(S), Engine Timing , Installation»(ref-462490-S08463944992012040500000) .
  8. Connect negative battery cable.
  9. Operate engine until it reaches normal operating temperature. Check oil and cooling systems for correct fluid levels.
