Use a torque wrench and a universal socket of the correct size and tighten the bolt to a torque of 22 2 lb.ft. (28 3 N m).18. Make sure the compressor wheel is clean and dry.
TYPICAL EXAMPLE19. Put the cartridge in a vise as shown. Check the shaft end play with tool (D). The end play must be .0045 .0015 in. (0.114 0.038 mm) (new). If the shaft end play is not the correct dimension, the inside parts of the cartridge housing must be checked for too much wear. See TURBOCHARGER (SCHWITZER FC452 in SPECIFICATIONS). 20.
