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.

INSTALLATION INSTRUCTIONS:

This bellhousing is not compatible with transmissions that were previously equipped with diesel engines. The bellhousing
design incorporates a special modified clutch release lever and a Toyota Land Cruiser slave cylinder. We have provided
slave cylinder mounting on the passenger side of the bellhousing; and have incorporated a new push rod location on the
release arm that will provide a quick short travel of the clutch release mechanism. The kit does not include the Toyota Land
Cruiser slave cylinder, Part No. 31470-60022. The bellhousing is designed for the 153 tooth flywheel application. If your
block is equipped with a 168 tooth flywheel, you will be required to use a high torque starter without a nose cone to fit
the bellhousing (P/N 22-0001). The bellhousing is compatible with the Buick flywheel that has 160 teeth. A slight
modification may be required in the starter pocket area when using the Buick installation.

The inside of the bellhousing uses a high profile Centerforce diaphragm clutch assembly. By using this pressure plate, you
can be sure that the slave cylinder travel will be appropriate for obtaining a maximum clutch release. The release bearing,

P/N N1430, is a standard flat faced Chevy release bearing. The bearing must not have continual contact with the fingers

of the clutch. Adjust the length of your push rod for clearance between the fingers and the face of bearing.
In order to adjust the height of the release bearing, we recommend that you install the new bellhousing over the clutch

assembly and onto the engine prior to assembling the transmission to the bellhousing. By doing this procedure, you will
be able to install the clutch release lever, slave cylinder, slave cylinder push rod, and release bearing directly to the clutch
assembly. The reason this is necessary is that there are variations as to the thickness of the flywheel which either raise
or lower the fingers of the clutch as related to the release bearing. The push rod of the slave cylinder can be adjusted, to
obtain the necessary clearance between the release bearing and clutch fingers. If the bearing is permitted continual contact
on the fingers, then you will have premature release bearing failure.

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.

CHEVY & BUICK ENGINES

We do not furnish a rubber boot for the area between the bellhousing and clutch arm since it is too restrictive for
the clutch arm movement. We believe that the location of the opening is such that any dust or other debris will have
a hard time accessing the opening. If you anticipate water hazards, we would recommend a small rubber flapper that
could be screwed to the outside of the bellhousing.

INSTALLATION INSTRUCTIONS:

1. Install the pilot bushing into the engine crank. Note: This bushing is oil impregnated. DO NOT USE ANY TYPE OF

GREASE ON THIS PART. (See illustration on Page 3 for depth of pilot bushing information).

2. Bolt the flywheel to the engine crank using special flywheel bolts.

3. Assemble the clutch assembly and special disc to the flywheel using special clutch bolts.

4. Assemble the clutch release arm to the inside ball pivot of the bellhousing.

5. Bolt the slave cylinder to the outside of the bellhousing.

6. Test fit the bellhousing assembly over the clutch assembly and onto the engine block.

7. Place the N1430 release bearing onto the clutch arm fork.

8. Adjust the length of the slave cylinder push rod to a length that provides a minimum of 1/8" clearance between the release
bearing face and clutch fingers.

9. The test fit over the clutch assembly is primarily done to establish the push rod length. If this procedure is eliminated,
you will not have any visual inspection for verifying the push rod adjustment.

10. Remove the bellhousing assembly from the engine.

11. In each kit, you will find a new transmission bearing retainer and seal that must be mounted in place of the original Jeep
bearing retainer.

12. Bolt the bellhousing to the front of your Jeep 5 speed transmission using the original bolts. Make sure that the two dowel
pins installed in the face of the 5 speed transmission are properly fitted to the AA bellhousing.

13. Slide the new release bearing onto the new AA bearing retainer. Make sure that there is grease in the internal cavity of
the release bearing. Most new bearings are pre-lubricated.

14. With all the components in position, you can now bolt the new bellhousing assembly onto the engine block. We have
provided six (6) new socket head bolts, 3/8"-16 x 1-1/2" long for this purpose. Make sure the engine dowel pins are
properly aligned with the new bellhousing dowel pin holes. DO NOT FORCE THE BELLHOUSING ONTO THE

ENGINE BLOCK. Some applications may require the tip of the input shaft to be modified slightly. The bellhousing

must fit evenly to the engine block.

15. With the bellhousing now in position and the slave cylinder push rod installed, you should be able to verify the clearance
between the release bearing and clutch fingers. The lever should have movement of approximately 1/8" to 1/4".

CAUTION: If you have too much clearance, you will be utilizing too much of the slave cylinder stroke and could

possibly prevent you from obtaining a full clutch release. A light duty return spring attached to the clutch release arm
will prevent any premature contact of the release bearing with the clutch fingers.

16. The Toyota Land Cruiser slave cylinder will replace the original Jeep slave cylinder. In order to adapt the Jeep hydraulic
line to the new slave cylinder, we have included a special fitting for this purpose. P/N 716130-60 is a new stainless steel
hose that works great for the connection of the slave cylinder to the master cylinder.

17. With the new slave cylinder installed, you can now bleed the slave cylinder installation by pumping up the slave cylinder
pedal. Most installations are compatible with the original Jeep master cylinder. We have encountered a few installations
that require changing of the master cylinder to a smaller 3/4" piston. If you have any type of clutch difficulty related
to full disengagement of the clutch assembly, contact Advance Adapters for any updated information.

18. Jeep used 3 different master cylinders with the YJ & TJ vehicles. Early models have a threaded connection while the
late YJ use a spade prong type & the TJ use a prong type with an o-ring. You may need to order P/N 716130 (for YJs)
or P/N 716130TJ (for TJs).

DUST COVER INSTALLATION:

Prior to transmission assembly, we recommend test fitting and assembling of the dust cover onto the bellhousing. Two of
the 4 holes have already been drilled for self tapping screws. The lower two holes will need to be drilled for 2 self tapping screws.
The drill size should be 11/64 (.171 Diameter), approximately 1/2" deep. On some applications, the new hole may enter the
slave cylinder mounting hole.
