Mainshaft Holding Socket Wrench

Tech Note 1: Mainshaft Nut
New Venture NV5600 6 speed manual transmissions use QU10850 hex mainshaft nut to retain QU12049 rear output ball bearing to the mainshaft. The nut is non-Reusable as it is staked in place during assembly. Installation torque for the nut is 250 Lb.ft (339 Nm) when using QT2026 Wrench.

Tech Note 2: Mainshaft Holding Socket Wrench
In addition to QT2026 Mainshaft Nut Wrench, you will also need a splined socket to prevent the mainshaft from turning. Use QT2000 29 Spline Wrench for 4x4s or QT2011 31 Spline Wrench for 4×2 transmissions. Both tools are 1/2″ drive.

Tech Note 3: NV5600 replaced by G56
The USA assembled New Venture NV5600 6 speed manual transmission with a cast iron main housing was available on 1999-2005-1/2 model year Ram 2500 and Ram 3500 trucks. Midway through the 2005 model year the NV5600 was replaced by the Mercedes designed and Brazilian made G56 6 speed with an all aluminum housing. The two transmissions have similar torque ratings.
