A quick question for you guys:
Why go through all of the work to install a secondary transmission when first gear could be replaced with a lower ratio gear set, moving the first gear to second possibly? I am pretty new at modifying gear sets and addressing the problem of too high of a gear for first. Thank you for your answers!
It does sound feasible, but there's so many dimensions to take into account, I imagine you'd be searching for a very long time or have to have them custom-made. 1st gear on the top shaft is also reverse, then it has to mesh nicely with the sliding 1st and reverse on the bottom shaft.
I guess a good engineer could draw one up within all the constraints. But I imagine the first set would cost a fortune in terms of CAD and set-up costs.
It might be possible to put a complete OC-4 transmission, which is has a more highly geared first gear, into an OC-3, similar to the early OC-4's with the 4 cylinder IXB engines (1957-8)?
