Use a hoist and lifting sling to aid in removing the flywheel housing. 

Install the lifting sling around both sides of the upper housing (1) and (2). Adjust the hoist until there is tension in the lifting sling.

Loosen, but do not remove, the flywheel housing capscrews.

NOTE: Identify the location of the flywheel housing capscrews as they are removed. Some of the capscrews are different lengths and size, and must be installed in the same location from which they were removed.

Remove the flywheel housing.

Remove the strip seal from the groove on the rear gear houing and discard.
