Prayers answered: New Inner Primary for ’65 thru ’69 Big Twins
So you finished rebuilding that vintage Panhead engine and made it shine again, or finally found the perfect frame for your Early Shovel chopper project? And the last piece to go into your Harley puzzle is that beat up, worn out inner primary, used and abused right up to the point of retirement? With its visible repair welds, the chain marks, the shaky main shaft bearing seat? Wouldn’t a brand new, sound inner primary be so much better? Long after Milwaukee stopped making them for ever, here’s a faithfully reproduced state of the art new casting of the OEM inner primary.
Cannonball has produced a limited run of Harley inner primaries (OEM 60615-65A) 1965 thru 1969. Sand cast from aluminium alloy and precision machined in Germany, with all the details for an easy and long lived installation included.

Original FL 1965-1969 primary covers are hard to come by or in bad condition. Tryinf to replace a →1969 primary cover with the 1970→ part is self-evident. But the starter shafts of FL models 1965-1969 are 7mm shorter than the starter shafts of 1970 and later FL models. This kit provides a means to close this gap and consists in a longer spacer and nut. It replaces the one-part starter shaft nut 31530-65.
