ENGINE MOUNTING/DISMOUNTING
E5U011002000E02
1. Install the SSTs (arms) to the cylinder block holes
as shown, and hand-tighten the bolts (part No.:
9YA20-1003) or M10
× 1.5T length 90 mm {3.55
in}.
2. Assemble the SSTs (bolts, nuts and plate) to the
specified positions.
3. Adjust the SSTs (bolts) so that less than 20 mm
{0.79 in} of thread is exposed.
4. Make the SSTs (arms and plate) parallel by
adjusting the SSTs (bolts and nuts).
5. Tighten the SSTs (bolts and nuts) to affix the
SSTs firmly.
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.
6. Mount the engine on the SST (engine stand).
7. Drain the engine oil into a container.
8. Install the oil pan drain plug.
• With washer
1. Install the oil pan drain plug with a new washer.
Tightening torque
30—41 N·m {3.1—4.1 kgf·m, 23—30 ft·lbf}
• Without washer
1. Inspect the seal rubber of the oil pan drain plug and make sure there are no cracks or damage.
— If necessary, replace the oil pan drain plug.
2. Clean the flange surface (seal rubber) on the oil pan drain plug, then install the oil pan drain plug.
Tightening torque
22—30 N·m {2.2—3.1 kgf·m, 16—22 ft·lbf}
DISMOUNTING
• Dismount in the reverse order of mounting.
