ARMY TM 9-2815-259-24 AIR FORCE TO 38G1-125-2 MARINE CORPS 09249A/09246A-24 5-51 (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. (c) Install woodruff key (5) in camshaft nose. (d) Position camshaft gear on camshaft nose with timing mark away from camshaft.  Carefully press camshaft gear onto camshaft using a Tubular Driver until camshaft gear bottoms against camshaft shoulder. (5) Lubricate camshaft bearing journals and camshaft lobes with High Temperature Grease (Appendix E). (6) Position thrust plate (3) on camshaft (1).
