Hi Guys!
I have a chance to get my hands on a speedo angle gear PN 91131802900 at a very good price. Is it compatible with 914 speedo gear PN 91431802901? Estetically, they look identical. Maybe it has different or reverse gearing? Any thoughts? |

there are some differences...even in the early 914 and later 914 ones...
they both turn either way so no problem with which way your engine is facing. what's different is the size of the gear "head" ...where the teeth are... I'll see if I have some pictures.... |

I'll see if I have some pictures.... The only angle drive listed for the 914 is 914-318-029-01. There was never a different angle drive for 914s. The 911 uses 911-318-029-00. If you look at the tail cone from a 911, you will see that the speedo drive connects to the input shaft on the top. The 914 speedo drive connects to the input shaft on the bottom. That makes them spin in opposite directions, and that accounts for the difference in the angle drives. |
