Engine Mounting/Dismounting

Mounting

1. Install the SSTs (arms) to the cylinder block four holes as shown in the figure, and hand-tighten the bolts (M10 x 1.5T length 90 mm {3.5 in}).






2. Assemble the SSTs (bolts, nuts, and plate) to the specified positions as shown in the figure.






3. Assemble the SST (bolts, nuts, and plate) set in Step 2 to the SST (arms) set in Step 1.






4. Adjust the SSTs (bolts) so that approx. 20 mm {0.79 in} of thread is exposed from the side of the SST (plate).

5. Make the SSTs (arms and plate) parallel by adjusting the SSTs (bolts and nuts).

6. Tighten the SSTs (bolts and nuts) to affix the SSTs firmly.

7. Mount the engine on the SST (engine stand).






WARNING:
- Self-locking brake system of the engine stand may not be effective when the engine is held in an unbalanced position. This could lead to sudden, rapid movement of the engine and mounting stand handle and cause serious injury. Never keep the engine in an unbalanced position, and always hold the rotating handle firmly when turning the engine.

Dismounting

1. Dismount in the reverse order of mounting.

Oil Pan Removal Note

1. Install two of the oil pan bolts temporarily into the two threaded holes in the oil pan.






2. Alternately tighten the two bolts one turn at a time until the oil pan-to-cylinder block seal is released.

3. Remove the oil pan.

Oil Pan Installation Note

CAUTION:
1 Apply silicon sealant in a single, unbroken line around the whole perimeter.
2 The oil pan and bolts must be installed and the oil pan aligned to the cylinder block within 5 min of sealant application. Final tightening of the oil pan bolts must be carried out within 60 min of sealant application.
3 Using bolts with the old seal adhering could cause cracks in the cylinder block.






1. Completely clean and remove any oil, dirt, sealant or other foreign material that may be adhering to the cylinder block and oil pan.

2. When reusing the oil pan installation bolts, clean any old sealant from the bolts.

3. Apply silicone sealant (Loctite 5900) to the oil pan along the inside of the bolt holes as shown in the figure.






Thickness
1 A: Approx. 3.0 mm {0.12 in}
2 B: 5.0-6.0 mm {0.20-0.23 in}
3 C: 10.0 mm {0.394 in}

4. Install the oil pan and the bolts to the cylinder block.
a. Tighten the bolts in the order shown in the figure.






Tightening torque
1 3.0 Nm {31 kgf-cm, 27 in-lbf}

b. Loosen the bolts 180 °.

5. Using a straightedge, align the oil pan flush with the rear of the cylinder block at the two areas as shown.






6. Tighten the bolts in the order shown in the figure.
