2 : Camshaft sprocket (EXH)
3 : Slack guide
4 : Timing chain tensioner
5 : Oil pump sprocket
6 : Oil pump drive chain
7 : Oil pump chain tensioner
8 : Crankshaft sprocket
9 : Tension guide
10 : Camshaft sprocket (INT)
A : Matching mark (dark blue link)
B : Matching mark (stamping)
C : Crankshaft key position (straight up)
D : Matching mark (stamping)
E : Matching mark (orange link)
F : Matching mark (outer groove*)

*: There are two outer grooves in camshaft sprocket (INT). The wider one is a matching mark.
