Cam/aux Pulleys

[jaimo]

As above I have a collection of 4 cam/aux pulleys are these all same and can they go any which way

2 have part numbers on and 24 stamped on one and 27 on the other

1 has like 1 dimple on and one has 2 dimples and the other two have none

All I know is the one with 24 stamped on it came off aux drive so which do I use for camshaft

Got a feeling it's one of the two on left for aux and one of two on right for cam

What does the 24 and 27 mean

Dimples are material removed to balance them after casting

IMHO they are the same

Put them face down then face up on a flat surface and check if the belt faces are at the same point

Thought so they all line up so basically use best 2
