NOTE: The 4.0L blocks originally mated to a manual transmission used a 2 piece pilot bushing. Both pieces must be removed,
the bearing and the sleeve. If these pieces are not removed, the new brass pilot bushing will not fit. We do not offer a smaller
pilot bushing to fit the reducer sleeve. On 4.0L that were originally mated to a automatic the new pilot bushing will fit without
any modifications.

RETAINER INSTALLATION:

The stock GM NV4500 transmission used an internal release bearing that mounts to the front aluminum bearing retainer housing.
Kits purchased before May 7, 1999, used a modified Dodge retainer (which was supplied in the kit). This retainer replaced the
GM aluminum retainer and provided the proper configuration to utilize the new release bearing assembly. If this bellhousing
was purchased with the intent to use a Dodge transmission with a new input shaft, your stock retainer must be modified. Refer
to Page 3 for machining specifications.

NOTE: If our bellhousing does not
index over the front retainer and the
retainer is aluminum, you could have
an after market retainer. The stock
NV4500 retainers should measure

5.5957" to 5.5977" in diameter.
Some after market one were .003" to
.007" larger in diameter. If this is
the case, you would need to modify
your retainer to fit our bellhousing.

Kits purchased after May 7, 1999, will retain the stock GM aluminum bearing retainer and will use P/N 716067A to obtain the proper
configuration. Part No. 716067A is a modified retainer that bolts to the stock GM retainer. We switched to this design due to
the fact that the stock Dodge retainer (used on the earlier kits) were no longer accessible.

Part No. 716067A is machined to index over the stock GM aluminum retainer. Once the retainer is indexed, rotate the 716067A
to line up with the two drilled & tapped holes located on the GM retainer. Using the two (2) 6mm fasteners & Loctite #242, secure
the 716067A to the GM retainer. NOTE: We have seen some aftermarket GM aluminum retainers that have a larger index hub.
This hub measures 4.408". Our retainer is machined to fit the stock GM retainer which measures 4.398". If our P/N 716067A does
not fit the aluminum hub on the NV4500 retainer, then one of the pieces will be required to be machined for proper indexing.

SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the components
will void any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion, we strongly
recommend that you contact our sales department for more information. This instruction sheet is only to be used for the assembly of Advance Adapter components.
We recommend that a service manual pertaining to your vehicle be obtained for specific torque values, wiring diagrams and other related equipment. These manuals are
normally available at automotive dealerships and parts stores.

Note:

2005 & Newer 4.0L engines use a new location and
style of crank position sensor. Shown in photo below
is the newer CPS location. If your engine is pre-2005,
please plug this hole with the 3/4" soft plug that has
been provided. Plug will need to be pressed or tapped
in using a dowel and soft hammer.

INSTALLATION INSTRUCTIONS:

Depending on the year of the vehicle that you are dealing with, you will need to vary the clutch control requirements
accordingly. The bellhousing that Advance Adapters has manufactured will use a GM clutch release arm along with
a GM clutch release bearing. Since you are using a GM transmission, the N1430 release bearing and GM clutch release
arm will work perfectly without any modifications. The new GM clutch arm will have an internal snap ring to lock onto
the ball pivot stud inside the new bellhousing. On Jeep vehicles that were originally equipped with a mechanical clutch
control, you should not have any problem adapting your original clutch linkage to the new clutch arm. On Jeep vehicles
that were previously equipped with a hydraulic slave cylinder such as 1987-2005 and 1980-1986 four cylinders, you
will need to use a Jeep slave cylinder that was used in the 1980-1983 Iron Duke four cylinder Jeep vehicles. We
recommend that you use the Advance Adapter Jeep clutch control slave cylinder kit, Part No. 716331. This new
assembly will include all the necessary parts to mount to the new bellhousing.

The bellhousing is a direct duplicate of the original AMC stock bellhousing. The flywheel sensor, dowel pin holes and
dust cover mounting holes are all in the original location. The original dust cover or block plate must be retained for
use with the Advance Adapter bellhousing. This plate is normally already on the engine block. The flywheel sensor
must be installed onto the new bellhousing using new bolts that we have supplied. These special bolts provide the
necessary accuracy to mount the sensor in the appropriate location.

Your new NV4500 transmission will require a new pilot bushing for the engine crank and possibly a new clutch disc.
The new transmission will require a Chevy clutch disc with a 1-1/8"-10 spline size Centerforce No. 384193. It is
advisable that you check the input shaft tip engagement into the new pilot bearing after installation. DO NOT FORCE

THE TRANSMISSION INTO POSITION. The flywheel must be 1" thick. We have seen some flywheels up to 1.5"

thick, which can cause interference problems. This 1" measurement should be taken from the crank flange to the clutch
disc surface. This bellhousing also requires the use of a diaphragm pressure plate. Most Borg & Beck 3 finger pressure
plates will not work.

CAUTION: On some of the early installations, we have encountered an interference problem between the
clutch pressure plate and clutch release arm. The solution is to grind the necessary clearance on the inside
of the bellhousing and modify the release lever approximately 1/16". It will be necessary that you check
the clutch clearance inside the bellhousing prior to transmission assembly. This problem has only occurred
with aftermarket clutch assemblies or thicker than normal flywheels.

SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the components will void
any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion, we strongly recommend that
you contact our sales department for more information. This instruction sheet is only to be used for the assembly of Advance Adapter components. We recommend that a service
