(7)   Place a new gasket (32) on pump body (38). Assemble    cover    (25)    to    body.        Press together using pilot capscrew near each end to pilot gasket. (8)   Secure  cover  to  body  with  lockplates  (17) and  screws  (16,  20,  and  21).    Check  drive shaft for freeness. (9)   Lock screws in position with lockplate tangs. d.     Replacement.  Proceed as follows: (1)   Remove   suction   tube   and   discharge   tube from oil pump and lift off pump. (2)   Position  lubricating  oil  pump  to  block  and secure    with    dowel    pins,    lockplates,    and capscrews. CAUTION Make sure that lubricating oil pump gear is  fully  engaged  before  final  tightening of capscrews. (3)   Attach   a   dial   indicator   to   block.      Place indicator on gear teeth. (4)   Rotate  gear  by  hand  to  advance  position; "zero"    indicator.        Back    gear    to    retard position     and     note     reading;     permissible backlash is 0.006 to 0.15 inch (0.15 to 0.38 mm).  If not within limits gear train must be replaced. (5)   Assemble lubricating oil suction and discharge   lines,   connections,   and   clamp, using new O-rings, gaskets, and lockplates. Torque  screws  to  30  to  35  foot-pounds  (41 to  47  joules).    Secure  lockplates.    Suction screen    must    have    1/2-inch    (12.70    mm) clearance.

(1)   Check for cracks or other flaws in flywheel, ring gear, and housing. (2)   Check  ring  gear  teeth  for  excessive  wear and   damage   from   improper   starter   gear meshing. (3)   Replace any damaged or cracked parts. b. Removal. (1)   Refer to Chapter 2, Section IV and remove the generator assembly to provide access to the flywheel housing. (2)   Remove    lockwires,    ten    screws    (1)    and lockwashers (2) securing flywheel to camshaft flange. (3)   Insert   two   5/8-18,   7-inch   (178   mm)   long studs     through     two     capscrew     holes     in flywheel  180  degrees  apart  and  screw  into crankshaft flange to support flywheel during removal. (4)   In  two  holes  provided,  place  two  1/2-13,  2- 1/2    inch    (63.5    mm)    screws    which    are threaded their entire length.  Turn in screws alternately  to  pull  flywheel  from  crankshaft dowels.  Using a suitable hoist, lift flywheel from guide studs.
