TM 5-3805-262-34 2-4. ENGINE TROUBLESHOOTING (CONT) MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 7. ENGINE STALLS FREQUENTLY OR DOES NOT DEVELOP FULL POWER (Cont). Step 13. (Cont). b. If end clearance is 0.010 inch or less, check for broken or missing thrust spring (page 4-54). Replace as necessary. c. If all of the above items are okay, check for worn connecting rod bearings or scored pistons (page 4-42), or worn crankshaft bearings (page 4-16). 8. ENGINE OIL PRESSURE OVER 60 PSI. Step 1. Remove engine oil pan (page 3-88). Remove oil pump (page 3-91). Notify general support maintenance to remove spring from oil pump (page 4-74) and check spring compression using spring gage. Pressure required to compress spring to 1.252 inches should be 23.8 to 25.6 pounds. a. Replace spring if pressure required to compress spring to 1.252 inches is not 23.8 to 25.6 inches (page 4-74). b. If spring is okay, go to step 2 below. Step 2. Disassemble oil pump (page 4-74). Inspect oil pump parts as described in page 4-76. Replace all defective parts; reassemble oil pump (page 4-77) and reinstall (page 3-94). 9. EXCESSIVE OIL CONSUMPTION. Step 1. Perform engine compression check (page 3-12). a. If compression check readings are low, go to step 2 below. b. If compression check readings are normal, go to step 4 below. Step 2. Put a small amount of oil in cylinder and repeat engine compression check (page 3-12). a. If compression check readings are now normal, replace piston rings (page 4-42). b. If compression check readings are still low, go to step 3 below. 2-31
