TM 10-3930-653-14&P Fig. 4-64.  Main Bearing Caps and Bearings (2)   Measuring lubrication (oil) clearance (1)   Measure    lubrication    (oil)    clearance    with    a    width gauge  (plastigage).    For  applicable  instructions,  refer  to paragraph on lubrication (oil) clearance measurement for connecting rod bushing. Tightening torque: Bearing cap 8.5 to 9.5 kg-m (61 to 69 ft-lb) (2)   If lubrication (oil) clearance exceeds prescribed limit, select   an   appropriate   replacement   part   from   service parts, checking crank-journal diameter.
