Anyone know these two 108mm applications?
Both (on the right) are 108mm course-spline flanges. But as the pic below shows, the center flange has the same dimensions as the 914 flange (left) on all turned surfaces. The 108 flange on the right is the same dimensions (on turned surfaces) as the 100mm SC flanges I use with 944 cv's on my 914. I can just barely make out what I think may be the part number on the rightmost flange. 915.332.209/01 but this may be incorrect. It's not very distinct. Anyone run into both at some point? My guess is that the flange on the right is from the SC era and the center one is an earlier turbo, but I'm basing that on the SC dimension match, not from actual fact. Ideas? |

Question answered by GT's Matt Monson. The longer ones are for the factory ZF LSD's and the shorter ones are for the open diff's. In a post on another board he stated the following on a different but related topic...
_________________________________________________________ The mag case 911 gearboxes (which includes the 1969 type 901s) use the same differential as the 914. The very early 915 gearboxes also use that same differential. If one were to acquire a factory ZF LSD for the 911/914 be sure to get the proper LSD stub axles flanges to go with it. The length is greater and the open diff flanges will be too short. ... The length to the step on a standard open diff flange is 56mm. The length to the step on the LSD version is 61mm... Our (GT) LSD or TBD does not require LSD flanges. You can use the stock open differential flanges with our units.
