When you're ready to install the main-shaft, mark the slot for the hub key in the syncro ring before placing it on the input shaft.







Use wire tie to hold the three hub keys. One is circled in photo. When you install the main-shaft this will allow the slider to be positioned forward for the gears to clear without the keys falling out of place. Then just slide the slider up enough to line up the black mark on the syncro ring and the key and drop the main-shaft into the input shaft.
