NOTES

In 1996, GM changed the NV4500 transmissions to an internal
hydraulic release bearing design. These new transmissions
have an aluminum bearing retainer installed on the front of the
transmission case. The bolt pattern on the transmission is the
same as the Dodge NV4500. In February of 1996, Advance
Adapter's introduced this new bellhousing as a solution to
installing these transmissions back to a conventional clutch
release arm design. The bellhousing adapter kit includes a new
Dodge bearing retainer that has been modified for use with a
stock GM clutch fork. If you are purchasing this item as an
adapter kit and are going to be installing your new bearing
retainer onto your transmission, it will be your responsibility
to verify proper main shaft end play. Refer to the service
manual for the correct procedure in determining the proper pre­load.

Most 1997 & up GM 4.3L V6 engines had a
larger crank I.D. The pilot bushing in this kit
requires a steel sleeve, P/N 716155.

NOTE: If our bellhousing does
not index over the front retainer
and the retainer is aluminium,
you could have an aftermarket
retainer. The stock NV4500 re­tainers should measure 5.5957"
to 5.5977" in diameter. Some
aftermarket ones were .003" to
.007" larger in diameter. If this
is the case, you would need to
modify your retainer to fit our
bellhousing.

DUST COVER INSTALLATION

The dust cover that we have furnished with this kit will fit all
Chevy engines up to 1986. If your engine is 1986 or newer and
used the large rear main seal, you will need to modify the inside
diameter of the steel sheet metal plate to allow for clearance
around the rear main seal area.

**SPECIAL PILOT BEARING NOTE:

Due to variations in both the transmission input shaft length
and bellhousing depth, it will be the customer's responsibility
to verify pilot bearing engagement from the new transmission
input shaft tip.

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:

We have found that when using the Zoom brand clutch
assembly and other "High Hat" style clutch assemblies, we
have encountered interference with the clutch arm. The only
modification for Zoom clutches would be to reduce the thick­ness of the flywheel. These style clutch pressure plates are not
recommended for use with this bellhousing.

BOOT NOTE: The throw out arm boot provided in this
bellhousing kit was designed for a Jeep throw out arm. The
arm provided in this kit is a Chevrolet arm. The boot may need
to be modified for the correct arm location in the boot.

GM BELLHOUSING FOR USE WITH

1996 GM NV4500 TRANSMISSION

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. See
below for machining specifications.

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.

NOTE:NOTE:

For customers that have a Dodge gas version transmission
and wish to use this bellhousing, you will need to purchase
a new Chevy input shaft, Advance Adapters Part No. 52-0221.
You will also need to machine your stock retainer. We have
enclosed this drawing for your reference.
