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.
Once the holes are marked, remove the casting and remove the main shaft out of the transmission. Using a drill press or
a mill, drill and tap the two holes marked on your T98 transmission, 3/8"-16 is recommended.
Care should be taken
to keep the inside of the case as clean as possible from chips of metal and dirt.
When assembling the gears onto the new main shaft, make sure that all gears have the proper end clearance required for
oiling. Make sure that all transmission assembly work is done by a competent mechanic. Warner gear has used two
different shaft designs for the spacer between second and third gear. Some transmissions will use a snap ring and thrust
washer, while others will use a built in shoulder. Both shafts are interchangeable. Install the new main shaft and gear
assembly into the Jeep T98 case.
The new seal provided with the adapter kit must be installed with the open side towards the transmission. The casting will
need to be installed on the T98. Use a small bead of RTV Blue Silicon on the backside of your transmission. Locate the
adapter onto the back bearing for indexing. Install the top two and new bottom two bolts and tighten. Insert the two socket
head bolts into the middle two holes and tighten.
NOTE: The two socket head bolts will protrude slightly into the
inside of the transmission case. Make sure they don't interfere with the gear. Shorten bolts if necessary.
With the adapter and transmission assembled, you are now ready to bolt the transfer case into position. We have included
a new gasket for added protection. Be sure to use RTV Blue Silicone on both sides of the adapter & gasket.
The skid plate will need to be slightly modified to fit under the new transmission. Two new holes may be necessary for
use with the new adapter and a slight notch may be required on the front leading edge of the skid plate for clearance around
the front drive shaft.
When this transmission is going to be used with an AMC 6 cylinder or V8 engine, you must use Jeep bellhousing No.
8133951, and Advance Adapters pilot bushing P/N 716156. The clutch disc should be changed to a 10 1/2", Centerforce
No. 384180.
