My shop manual shoes the ring and pinion as the first reduction and then either high or low speed second reduction. The manual also shoes the ratios as low 8.10 and high 6.13. I went out to the cold shop and 8.10 and 6.13 are stamped on my case. The manual does not show what the ratio is for the first reduction (ring and pinion) and I believe the 8.10 and 6.13 are a combination of the first and second reduction.
