TM 5-3895-373-34 E. INSTALL - Continued. Use care when installing snap and retaining  rings.    Snap  and  retaining  rings are  under  spring  tension  and  can  act  as projectiles when released and could cause severe eye injury. e. Use   inside   snap   ring   pliers   to   install   retaining rings (104). f. Using  piston  ring  expanding  tool,  install  piston ring (101) on piston, with latch pin entering both ends of the spring. g. Install piston ring (102) on piston with manufacturer’s mark facing toward top of piston. h. Install piston ring (103) on piston, with manufacturers’s    mark    facing    toward    top    of piston. NOTE If sleeve bearings are reused after removal,  make  sure  sleeve  bearings  are reassembled in original position as tagged. i. Install  sleeve  bearings  (100)  on  connecting  rod assembly (97).  Ensure oil hole in sleeve bearing aligns with oil hole in connecting rod assembly. j. Lubricate sleeve  bearings  (100)  generously  with engine oil. 7. INSTALL    PISTONS    AND     CONNECTING     ROD ASSEMBLIES INTO ENGINE. a. Lubricate each cylinder bore and piston generously with clean engine oil. NOTE Each piston and connecting rod assembly  must  be  replaced  in  the  same cylinder bore from which it was removed. Use  the  following  list  of  checks  to  make sure piston was assembled correctly, and is replaced in correct position. Piston    and    connecting    rod    assembly number must match (1 through 4) cylinder bore number. NOTE Rod identification number must be on the     fuel     injection     pump     side     of connecting rod assembly. The   word   "FRONT"   marked   on   piston crown must point toward front of engine. b. Use  a  piston  ring  compressor  to  insert  pistons (98) into respective cylinder bores. GO TO NEXT PAGE 2-219
