MAINTENANCE OF THE M113 PER CARRIER - OD1601 LESSON 2/TASK 1
CAUTION
Limit the stall test to 30 seconds. Lengthy full throttle
operation
with
the
brakes
locked
creates
high
oil
temperatures and will damage the engine and transmission.
(6) Observe tachometer reading.
A reading of 1,900 to 2,100 rpm indicates the
engine and transmission are both operating correctly.
(7) If tachometer reading is above 2,100 rpm, the transmission is at fault.
Notify support maintenance personnel.
(8) If tachometer reading is below 1,900 rpm, the engine is at fault.
Notify
support maintenance personnel.

After-Road-Test Services.
(1) Maintenance Services.
Perform after-road-test
services
and

any
defects noted during road test and inspection.
(2) Lubrication.
Inspect and lubricate, if necessary, in accordance with LO 9-
2300-257-12 or LO 9-2350-300-13, as applicable.
If the carrier is receiving a
1,000 mile service at this time, record the lubrication interval on DD Form 314,
Preventive Maintenance Schedule and Record.
(3) Final Road Test.
After all services and inspections have been completed,
take the carrier on a short road test to ensure that operational difficulties have
been corrected. Pay particular attention to those items found defective initially.
Correct any remaining problems noted during this test run.
