Remove front timing chain case. Refer to "Removal and Installation ".
Check timing chain markings to confirm No. 1 cylinder is at TDC of its compression stroke.
- If not, remove Ring Gear Stopper Tool and turn crankshaft clockwise 360° (one revolution).
- Re-install Ring Gear Stopper Tool.
  Tool number: - (J-48761)
- If the original timing chain markings are not legible, use paint or equivalent to mark the timing chains to the sprockets.
If removing the secondary timing chains, loosen camshaft sprocket bolts.
Compress the primary timing chain tensioner.
1. Loosen clip of primary timing chain tensioner, and release plunger stopper (1).
2. Depress plunger into tensioner body by pressing slack guide (2).
3. Keep slack guide pressed and insert stopper pin through the tensioner body hole and plunger groove (3) to hold plunger in.
  NOTE: Use stopper pin included with Tool J-50246.

Remove timing chain (primary).
CAUTION: After removing timing chain (primary), do not turn crankshaft and camshaft separately, or valves will strike the piston heads.
Remove crankshaft sprocket, if necessary.

2. Remove camshaft sprocket (INT and EXH) bolts.
3. Remove timing chain (secondary) together with camshaft sprockets.
  - Turn camshaft slightly to secure slack of timing chain on timing chain tensioner (secondary) side.
  - Insert 0.5 mm (0.020 in)-thick metal or resin plate between timing chain and timing chain tensioner plunger (guide). Remove timing chain (secondary) together with camshaft sprockets with timing chain loose from guide groove.
    CAUTION: Be careful of plunger coming off when removing timing chain (secondary).
    
    NOTE: Camshaft sprocket (INT) is a one piece integrated design with sprockets for timing chain (primary) and for timing chain (secondary).
