The standard single sheave pulley only works for the 100 amp alternator. It is the 61-0010 and is 2.7" in diameter. If you order a 6 series alternator where the part number ends in SV this is what you will get. For larger alternators you will need one of the other options. You can also order 6 series with a dual V pulley, the part number will end in DV and the standard pulley is the 61-0020 which is also 2.7" in diameter. You can also get these alternators with 6 groove K6 pulleys or 10 groove K10 pulleys. The standard K6 pulley is 61-0070 and is also 2.7". We can special order other pulleys as needed.
