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.
