  56.  

To install:

  1. Check the torque converter hub and hub drive flats for sharp edges burrs, scratches, or nicks. Polish the hub and flats with 320/400 grit paper and crocus cloth if necessary. Verify that the converter hub O-ring is properly installed and is free of any debris. The hub must be smooth to avoid damaging pump seal at installation.
  2.

  18.  
  19. Apply a light coating of high temperature grease to the torque converter hub pocket in the rear pocket of the engine-s crankshaft.
  20.  
  21. Raise the transmission and align the torque converter with the drive plate and transmission converter housing with the engine block.

  48.  
  49. Install the starter motor and cooler line bracket.
  50.  
  51. Connect the cooler lines to transmission.
  52.  
  53. Install the transmission fill tube.
  54.  
  55. Install the exhaust components.
  56.  
  57. Align and connect the propeller shaft(s).
