TM 10-4320-307-244-17CRANKSHAFT ASSEMBLY REPLACE:REPAIR (CONT)13. If bearing journals are only slightly outside specified limits because of nicks. burrs. or high spots. remove these slightimperfections with crocus cloth wet with lubricating oil. Work wet crocus cloth evenly around circumference of journaluntil surface is polished smooth. If wet crocus cloth is not effective, use emery cloth. 120 grit for removing imperfec-tions and 240 grit for finishing. Polish smooth with wet crocus cloth. Use a piece of rawhide or other suitable ropewrapped around the emery cloth or crocus cloth and drawn back and forth will minimize the possibility of an out-of-round condition developing (keep the strands of rawhide apart to avoid bind). If rawhide or rope is not used, thecrank- shaft should be rotated at intervals. If the above procedure is not effective or imperfections are too great, thecrank-shaft must be replaced.14. Stone edges of all oil holes in bearing journal surfaces with surfacing stone to provide a smooth radius.Death or serious injury could occur if diesel fuel oil is not handled carefully.Use in a well ventilated area away from open flame, arcing equipment, ignitionsources, heaters, or excessive heat. Always store fuel in proper. markedcontainers. DO NOT SMOKE.15. Polish ground surfaces to an 8 to 12 RMS finish with crocus cloth wet with diesel fuel oil16. Inspect crankshaft thrust surfaces. If slightly wornor grooved, smooth out and polish surfaces withwet crocus cloth. Make sure to leave a 0.1693 to 01772 inch (4.30 to 4.50 mm) radius (5) oncrankshaft between each thrust surface (6) andbearing journal (7) or crankpin.17. Clean up minor burrs and gouges of shaft seal and preformed packing seats with emery cloth. Repair any minordam-age, nicks, burrs, rust, or corrosion. If defects cannot be removed, replace rear-end cover.4-130
