ARMY TM 9-2815-260-24 AIR FORCE TO 38G1-126-2 MARINE CORPS TM 09244A/09245A-24 5-51 (c) Record camshaft lobe height and compare with specifications given in Table 5-3. Table 5-3.  Camshaft Lobe Height Specifications. Camshaft Lobe Height = Widest lobe point measurement - Narrowest lobe point measurement Intake Valve Camshaft Lobe Height 0.273 - 0.292 in. (6.93 - 7.42 mm) Exhaust Valve Camshaft Lobe Height 0.266 - 0.286 in. (6.76 - 7.26 mm) (d) Repeat steps a and b for all camshaft lobes.  Replace camshaft and camshaft followers if any camshaft lobes are not within specifications. (e) Measure fuel supply pump camshaft lobe diameter using micrometer.  Fuel supply pump camshaft lobe diameter should be 1.680 - 1.690 in. (42.67 - 42.93 mm).  Replace camshaft and camshaft followers if fuel supply pump camshaft lobe diameter is not within specification. (6) Position camshaft thrust plate on camshaft and check clearance using a feeler gage.  Camshaft thrust plate clearance should be 0.003 - 0.009 in. (0.08 - 0.23 mm).  Replace camshaft thrust plate, camshaft, or both if clearance is not within specification. (7) Install camshaft, refer to step f. e.     Replacement. (1) Remove camshaft, refer to step c. (2) Perform test procedures, refer to step d.  Replace camshaft if it fails any portion of test. (3) Install camshaft, refer to step f. f.   Installation. (1) Remove all covering installed during step c (18). (2) Ensure that engine is locked with No. 1 piston at TDC compression stroke using Timing Pin (JDE81-4). (3) If camshaft is being replaced, remove cylinder head and replace camshaft followers, refer to paragraph 4.7.4. (4) If necessary, install camshaft gear on camshaft as follows: (a) Support camshaft (1, Figure 5-61) under first bearing journal in hydraulic press. (b) Apply High Temperature Grease (Appendix E) to camshaft nose and camshaft gear inner diameter.
