Layshaft c/w 2nd and high gear (17/23T)
Gearbox layshaft assembly complete with 2nd and high gear (17/23T), catalog number 57-1972 (alias T1972).
This is the layshaft assembly for the gearbox, listed in the catalog as coming complete with 2nd and high gear cut 17/23T. In the old parts books it shows up under the T1972 designation, same physical part as today's 57-1972.

The layshaft sits inside the gearbox shell, called out in the GEARBOX SHAFTS, BEARINGS AND INNER COVER section of the parts books, and carries the second and high (top) gear pinions as part of the shaft assembly. It's a shaft-and-gear unit rather than a bare shaft, so when you're ordering you're getting the layshaft with those two gears already on it.
Our catalog record ties this part to gearbox work spanning several years of production without pinning down one specific model, so if you're matching it against a rebuild, check the tooth count and shaft dimensions against what's coming out of your case before you order.
