CAMSHAFT

REMOVAL−ENGINE REMOVED FROM VEHICLE

Remove intake manifold, cylinder head covers, cylinder heads, timing chain case cover and timing chain.

(1)Remove rocker arm and shaft assemblies.

(2)Remove push rods and tappets; identify so each part will be replaced in its original location.

(3)Remove camshaft thrust plate (Fig 10).

(4)Install a long bolt into front of camshaft to facilitate removal of the camshaft; remove camshaft, being careful not to damage cam bearing with the cam lobes.

Fig. 11 Camshaft and Sprocket Assembly

Whenever an engine has been rebuilt or a new camshaft or tappets have been installed, add one pint of Chrysler Crankcase Conditioner or equivalent to engine oil to aid in break in. The oil mixture should be left in engine for a minimum of 805km (500 miles) and drained at the next normal oil change.

(2)Install camshaft thrust plate with two screws as shown in (Fig. 10). Tighten to 12 Nzm (105 in. lbs.) torque.

(3)Place both camshaft sprocket and crankshaft sprocket on the bench with timing marks on exact imaginary center line through both camshaft and crankshaft bores.

(4)Place timing chain around both sprockets.

(5)Turn crankshaft and camshaft to line up with keyway location in crankshaft sprocket and in camshaft sprocket.

(6)Lift sprockets and chain keep sprockets tight against the chain in position as described.

(7)Slide both sprockets evenly over their respective shafts use a straightedge to check alignment of timing marks (Fig. 12).

(8)Install the camshaft bolt. Tighten bolt to 54 Nzm (40 ft. lbs.).

(9)Rotate crankshaft 2 revolutions. Timing marks should line up. If timing marks do not line up, remove cam sprocket and realign.
