Component (2WD Models)".
21. Loosen two mounting bolts in front of oil pan (upper) with power tool in reverse order shown in figure.
22. Remove front timing chain case as follows:
a. Loosen mounting bolts with power tool in reverse order as shown in the figure.
b. Insert suitable tool into the notch at the top of front timing chain
case as shown (1).
c. Pry off case by moving a tool as shown (2).  Use the seal cutter [SST: KV10111100 (J37228)] to cut liquidgasket for removal.

e. Tighten mounting bolts in numerical order as shown in the fig-
ure.
9. Install crankshaft pulley as follows:
a. Fix crankshaft using the ring gear stopper [SST: KV10117700 (J44716)].
b. Install crankshaft pulley, taking care not to damage front oil seal.  When press-fitting crankshaft pulley with plastic hamme r, tap on its center portion (not circumference).
c. Tighten crankshaft pulley bolt.
d. Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt.
e. Further tighten by 90 degrees. (Angle tightening)  Check the tightening angle by referencing to the notches. The
angle between two notches is 90 degrees.
10. Rotate crankshaft pulley in normal direction (clock wise when viewed from front) to confirm it turns
smoothly.
11. For the following operations, perform steps in the reverse order of removal. NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in the guide may gener-
ate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak. Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to GI-44, "
Recommended Chemical Product and Sealant".
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside chain tensioner drops af ter removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.
 Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil and engine coolant.
 Bleed air from lines and hoses of applic able lines, such as in cooling system.
