Applications

Tech Note 1: Assembly Numbers 
QI51201 23 spline Input Shaft is the aftermarket Replacement Input Shaft for these 1994-2001 Dodge Ram NP241 transfer case assembly numbers: 52098503, 52098505, 52098675, 52098677, 52105023AB, and 52105026AB.

Tech Note 2: Automatic Transmissions
Dodge used 23 spline 46RH (Gas V8) and 47RH (Diesel, V10) Automatic Transmission for the 1994 and 1995 model years. NP241DLD and NP241DHD NP241 series Transfer Cases that mate with the RH series transmissions use a 5" (approximate length) 23 spline input shaft. A 4-5/16" long input shaft is used for transfer cases that mount to 1996 and later RE series automatic transmissions.

Tech Note 3: Manual Transmissions
From 1994 to mid 2001 manual transmissions, Dodge used the 23 spline output New Venture NV4500LD 5 speed manual transmission in V8 equipped Ram 2500, Ram 3500 4x4s. The matching transfer cases all have a 5" (approximate length) 23 spline input shaft.

Tech Note 4: Planetary Tooth Cut
under construction

Tech Note 5: Input Bearing Width
1994-2002 Dodge Ram NP241DLD and NP241DHD Transfer Cases were built with input shafts  using either a narrow (5/8” wide) or wide (15/16” wide) Input Ball Bearing. While a narrow bearing cannot be used on an input made for the wide bearing and visa-versa, the combined matching bearings and shafts are totally interchangeable. For example, If you are doing a manual transmission swap on a 1998 Automatic transmission equipped Cummins powered truck with NP241DHD Assembly number 52105027, you can replace the original QU50640 input shaft/QU50874 Narrow Bearing with QU10889 29 Spline Input/QU50873 Wide Bearing.

Tech Note 6: Pilot Bearing Bore
The Bearing Bore for the Input to Mainshaft Pilot Bearing is 1-5/8". For Dodge Ram NP241 applications, order EITHER X10000 Mainshaft Front Pilot Bearing + QU50083 Cup Plug OR QU50114 One piece Unitized Input Needle Bearing. An optional steel adapter ring for using this input with smaller transfer cases like the NP231 will be available soon.
