Model 52K Generator

The Model 52K generator was used on the 1952-1956 K and KH, and the 1957 Sportster. From 1952 to ~1955, the ID was on a tag. Then from ~1956 to 1957, the ID was a stamping. These dates are approximate.

WARNING: The K-models used a 52K generator. Harley also made a Model 52 generator, which was used on Panheads, but not on the K-models.

I have seen this regulator mounting setup a couple of times, and I do not know if it is stock. The 1954 Spare Parts Catalog shows a 1/2" long bolt and plain nut.
