TM 9-2350-261-20-l Table 2-1. Unit Level Preventive Maintenance Checks and Services for M113A2 FOV L Item Interval Item To Procedure Not Mission No. Be Capable If: Inspected 5 S e m i - S t a ll If outside air temperature is greater Annual Check than 85° F (29° C, normal operating temperature should be 160° to 230° F Continued (71° to 110° C. CAUTION Limit stall test to 30 seconds. Lengthy full throttle operation with brakes locked creates high oil temperatures and will dam- age engine and transmission. If you suspect a faulty governor, do not perform stall check. With brakes locked, move range selec- tor to the 2-3 range and push accelera- tor all the way down. Tachometer reading of 1900 to 2100 rpm indicates power plant is operating correctly. NOTE Tachometer above 2100 rpm or below 1900 rpm. Extremely high ambient tem- perature and high altitude will lower stall speed. NOTE U s e S T E - I C E t o v e r i f y t h e T a c h o m e t e r i s c a l i b r a t e d o r t o g e t a r e a d i n g w h e n performing a stall check. See page 3-284 for STE-ICE Test 10 Engine RPM. NOTE If check fails and a faulty tachom- eter is suspected, verify tachom- eter reading by performing STE- ICE check number 10 (page 3- 284) before sending to next higher level of maintenance. Tachometer reading above 2100 rpm indicates transmission problems. Tachometer reading below 1900 rpm i n d i c a t e s a f a u l t y e n g i n e . Troubleshoot fuel system (page 3-30). Check for correct vehicle tachometer adapter. If no fault can be found, con- tact next higher level of maintenance. Change 4 2-45
