Stock crank pulley snout differences?

[richierich]

I've been wondering about this. On stock crank pulleys - I know that there are differing sizes in the diameter of the pulley itself however, does anyone know if there were differing pulleys - in the sense of the depth of the snout (the grooved oil slinger section) where it protrudes into the case and sits against the slinger washer and the relative positioning of the belt to line it with the alternator pulley? This is assuming no spacers or shims would be used? Or, were ALL stock crank pulleys the same in this respect?

If the hubs are all the same or not, there would be the additional question of... is the vee belt groove always located the same relative to the hub.

In my experience the 1200, 1300, 1500 & 1600 Type 1 engines all had the same crank pulley. The case bores were all 50 mm diameter as well, and I assume the snout-to-slinger depth is the same.

There is a 38 amp generator that was used on the early bay window buses that was longer and can cause pulley misalignment, if you don’t have the matching generator backing plate and spacers. My 69 bus had this setup and I believe that continued up to 1971 until the end of the 1600 cc Type 1 bus engines.

There is an oversized pulley for cases that are worn but the oversize is the diameter of the grooves of the pulley is a bit larger. I have one in my parts stash.

I do not know any with a longer snout on the pulley. You can always add spacers/shims usually used for sand seal pullies if needed: https://www.cbperformance.com/product-p/1915.htm
