SPECIAL INSTALLATION INSTRUCTIONS

The NV4500 bellhousing that is available from General Motors has a hydraulic release bearing located on the passenger
side of the vehicle. This makes the bellhousing incompatible with 4WD vehicles that have the front driveshaft on the
passenger side. In order to install these new transmissions in older Chevy trucks, Jeep vehicles, and Toyota Land
Cruisers, we have manufactured this new aluminum bellhousing. The indexing bore in the bellhousing is 5.125" and the
four (4) tapped bolt holes are 7/16"-14.

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.

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
or you can also use a new GM
bearing P/N 12557583

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.

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. It may be necessary on some installations
to leave the pilot bearing extending approximately 3/16" from the crank location.

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.

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.

NOTES:

1 . Be sure to grease inside pocket diameter of bearing. This will provide lubrication

on the bearing retainer.

3. Clutch disc should have .030" clearance between flywheel and disc when fully
disengaged.

4. On large diameter 168 tooth flywheels it may be necessary to grind additional
clearance on the lower inside diameter of the bellhousing. The bellhousing is
designed for a maximum flywheel thickness of 1.188".
