The Master Rebuild Kit 

Our master rebuild kit has been assembled for our customer's rebuilds as well as our own. It is the most complete kit we've seen anywhere and features the recommended consumable and wear item components.

Because there are a few chain options for the NP242, we recommend it be purchased (below) for the most complete rebuild possible. We consider chain replacement to be very important.


All kits include all the bearings, seals, gaskets, small parts, and instruction guide. 

Applications & Compatibility 

NP231 Versions 

NP231's are consistent from 1988-1993. Beginning in the 1994 model year, New Venture changed the front input bearing from a wide version to a narrow version. By 1995, the change-over was complete, but individuals with 1994 model year transfer cases can't always be certain of which bearing their transfer case may actually have, unless they pull the front bearing retainer or even fully disassemble the NP231 and check this input gear bearing.

  • The early NP231 uses a BD50-8 bearing, measuring 24mm wide
  • The later NP231 uses a 6010-N bearing, measuring 16mm wide


The earlier style input gear, left, has a wide bearing journal. The later style input gear, bottom, has a narrow bearing journal.

Installation Requirements

It is very common for our customers to do top-level rebuild work, using good methods and by following our included instruction guide. We suggest the rebuilder have access to a set of snap ring pliers, and a small arbor press, in addition to standard shop tools.
