2.
Install gear spacer ring and thrust plate/retainer over end of camshaft, then seat Woodruff key in shaft keyway.
3.
Mount timing gear on shaft ensuring that keyway is aligned with Woodruff key, then press gear onto shaft until it bottoms against spacer ring.
4.
Measure clearance between thrust plate and front camshaft journal. If clearance is not .0015-.005 inch, thrust plate should be replaced.
INSTALLATION
1.
Coat camshaft journals and lobes with assembly lubricant.
2.
Insert camshaft into bearing bores, taking care not to damage bearings.
3.
Rotate crankshaft and/or camshaft as needed to ensure stamped timing marks are aligned when camshaft is fully seated in block.
4.
Install thrust plate retainer bolts, and tighten bolts to specifications.
5.
Align and install front cover assembly as outlined in FRONT COVER.
6.
Reverse remaining procedure to complete installation. With cam and crankshaft timing gear marks aligned, engine should be in number 4
cylinder firing position and distributor can be indexed to marks made during removal procedure. However, if crankshaft is rotated
during reassembly, rotate crankshaft until engine is in firing position for number 1 cylinder, with timing mark on balancer indexed at
TDC on timing pad, then install distributor with body in original position but with rotor arm pointing toward number 1 cylinder spark
plug contact in cap.
