Parts for the

New Process 242 Transfer Case

The New Process / New Venture 242 transfer case has turned out to be one of the greats in Jeep history, as well as other applications such as the Humvee. Having rebuilt countless 242's and as a manufacturer of parts for them, no company knows them like Novak.

Master Rebuild Kits

An NV NP 242 Rebuild Kit

Kit Features

Our master rebuild kit has been assembled for our customer's rebuilds as well as our own. It is hands-down the most complete kit we've seen anywhere and features all the consumable and wear item components, including the bearings, seals, gaskets, small parts, chain, magnet, oil filter, boot, shift lever bushing, thread locker compound, RTV sealant, face studs and instruction guide (not all items shown in image).

A chain is not included in our 242 master kit, but is strongly recommended that you replace. Please read about Chains, below and select the correct one in Related Products, below. These are the highest grade chains available.

  • Kit 242MR-1, master rebuild, NP242 transfer case, Jeep 1987-1993, earlier wide bearing style

  • Kit 242MR-2, master rebuild, NP242 transfer case, Jeep 1994-, later narrow bearing style

  • Kit 242MR-3, master rebuild, NP242 transfer case, Jeep Liberty Version

NP242 Versions

NP242's input bearing widths 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 NP242 and check this input gear bearing.

  • The early NP242 uses a BD50-8 bearing, measuring 24mm wide
  • The later NP242 uses a 6010-N bearing, measuring 16mm wide


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

NP242 Transfer Case Chains


There were five chain versions available in the NP / NVG 242 transfer cases. They generally fall into the applications as listed below. However, if you are at all uncertain about your 242, you can open it up and inspect the pitch of your chain (by measuring between links) and the link type as illustrated below:


Use the above illustration in the event you may not be certain about the provenance of your NP242 transfer case and the chain type it features.

Jeep XJ (US) & ZJ Version, 1989-2000 (most common in Jeeps unless it has a V8)

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.
