There was lots of trouble with the 61/62 mm pulleys to start as there was too little material left between belt rib and bearing. This caused lots of damaged cars. This pulley is not made anymore I believe, replaced by the 65 mm. Is this one of them, the smaller bearings used a 5 mm spacer. This does not look like one of them though. It is aluminum which is not good for this job.
What is the actual OD of this pulley?
If it is 62 mm (2.440") 65 mm is 2.56" diameter
Lets do some simple arithmetic here, Pulley OD is 62 mm you say, depth of grooves are 3.5 mm.
62 - 2 x 3.5 = 55 mm = OEM pulley diameter.
What am I missing?
