I know of three different 1275 crank tails.
But one of those is RWD.

I have a few primary gears and am unsure if they are 1275 or something else. How do I determine if a primary gear is 1275 or not apart from physically sticking it on a 1275 crank? (Are all 1275 primary gears the same... ie mk1 S, mk2 S, 1100S etc) Brenton |

The small bore ones have the same diameter bush in each end. 1275 is bigger on the engine side bearing |

So do small bore and 1275 primary gears have the same number of teeth? |

yes I believe so. 998s machined will fit a 1275 |
