ENGINE INTERNAL ASSEMBLIES 7-8.1.  ENGINE  COMPRESSION  TEST. The  engine  cylinder  compression  tests  of  this paragraph may be used to determine the condition of engine valves, pistons, piston rings, and cylinders. Normal cylinder pressure should be between 350 to 450 psi,  depending  upon  engine  condition.  Corrective maintenance  should  be  considered  if  cylinder  pressure is below 325 psi or if there is a pressure difference of 15% or more between cylinders. These pressure ratings apply to a warm engine at cranking speed (approx- imately  300  rpm). a.  Compression  Test. (1)  Run  the  engine  until  normal  operating temperature  is  reached. (2) Stop engine and remove all injector nozzle assemblies in accordance with paragraph 7-20a. (3) Disconnect and tag wires to governor fuel shut off solenoid (K5). (4) Obtain or fabricate two compression adapter mounting studs (see table 2-2). (5)  Install  two  compression  adapter  mounting studs (3, figure 7-8.1) into cylinder head (13) in place of screws (1, figure 7-45). (6) Assemble gasket (7, figure 7-8.1), adapter (8), gasket (9), heat shield (10) and gasket (11) on compres- sion adapter (6) (see table 2-l). (7) Install compression adapter and assembled parts into cylinder head opening (12) of cylinder head (13). (8) Install retainer flange (5) over compression adapater studs (3) secure compression adapter (6) to cylinder  head  (13)  with  two  MS51967-2  nuts  (2)  (from bench stock) and washers (4). (9) Connect compression tester gage (1) (see table 2-1)  to  compression  adapter  (6). (10)  Crank  the  engine.  Read  and  record  cylinder pressure as indicated by the compression tester gage. (11) Remove nuts (2) from studs (3). Disassemble and remove items 4 through 11 from cylinder head (13). Diesel   engines   have   very   close clearances. Too much oil squirted into the cylinder may cause a hydrostatic lock and damage the piston when the engine  is  cranked  with  compression adapter and tester gage installed. (12)  Squirt  a  small  amount  of  oil  (approximately 30 drops) into the cylinder through the cylinder injec- tor opening (12). (13)  Assemble  and  reinstall  items  removed  in  step (11)above. (14)  Crank  the  engine.  Read  and  record  cylinder pressure.  If  the  cylinder  pressure  has  increased  con- siderably  from  the  pressure  recorded  in  step  (10) above, the rings and cylinder bore should be checked for correct tolerances and wear limits. (15) If the cylinder pressure has increased only slightly,  the  mating  surfaces  of  the  valves  should  be checked  for  abnormal  conditions. (16) Repeat steps 5 through 15 for each cylinder. (17) Install injector assemblies in accordance with paragraph  7-20i. (18)  Reconnect  wires  to  governor  fuel  shut  off solenoid  (K5). Change  3 7-9
