1. Write down all radio station presets.
2. Disconnect both battery cables, negative cable first.
3. Remove the secondary timing chains. Refer to the Electronic Service Manual (ESM) if needed.
NOTE:
It is not necessary to remove the valve covers or intake collector.
^ Before removing the crankshaft pulley, set it to 0° Top Dead Center (TDC).
^ Use Tool J-48761 to secure the flywheel / flex plate when removing the crankshaft pulley and camshaft sprockets. Figure 1 shows J-48761 installed on
an AWD vehicle.
NOTE:
The camshaft sprockets bolts will be removed and installed while being held by all three (3) timing chains.
^ If the crankshaft is determined to be 360° off from 0° TDC on #1 cylinder compression stroke after removing the front timing chain case (front cover),
put the crankshaft pulley back on, and then rotate the crankshaft 360° (when camshaft and crankshaft sprocket mating marks are aligned).
^ Use the chain tensioner pins (pin) from Tool Kit J-50246 to hold all three (3) chain tensioner plungers. Figure 3 shows a pin used on B2 tensioner.
NOTE:
The primary timing chain will be reused. If the original markings are not legible, it is recommended to mark this chain to all three sprockets with
"white-out" or suitable marking before removing.
