Start By:a. remove cylinder headb. remove front and rear housingsc. remove rear seal and carrierd. remove pistons and connecting rods 1. Remove bolts (1), remove main bearing caps (2) and remove thrust bearings (3) from the center main. 2. Install two bolts and nylon strap (4) then carefully, remove the crankshaft. The approximate weight of the crankshaft is 129 Kg (284 lbs.).3. Remove the upper portions of the main bearings. The following steps are for the installation of the crankshaft. Be sure main bearing tabs engage the grooves in the block and cap.4. Position the upper portion of the main bearings in the block and the lower main bearing portion in caps (2).

Put engine oil or molylube on the bolt threads and the washer face, then install bolts (1). Tighten the bolts on the side where the main bearing tabs are located to a torque of 95 5 N m (70 4 lb.ft.). Tighten the bolts on the opposite side to a torque of 95 5 N m (70 4 lb.ft.).8. Put mark on each bolt head and the bearing caps. Turn the bolts that are opposite the main bearing tabs an additional 90° 5° turn.
