The bellhousing is designed to be used with a stock 1988 to 2001 Jeep clutch assembly,
or Centerforce pressure plate
(P/N CF361890) & clutch disc (P/N 384193) . The release
bearing on this bellhousing is designed to ride constantly against the pressure plate. The
recommended slave cylinder has a certain push rod length for proper clutch operations. If the incorrect pressure plate or disc is used, or
the stock flywheel has been resurfaced, proper clutch operations may be effected.
The flywheel should be 1" thick.
This bellhousing can be use with a stock Jeep slave cylinder from the 2000 & 2001 Jeep "TJ"; however, the slave cylinder from Chrysler
is only sold as an assembly which includes a master cylinder and plastic hose. This assembly retails for close to $200.00. The biggest downside
of this assembly is when trying to use it on an early style "YJ". The slave cylinder is the only part you can retain, and you would still require
some additional components for this slave cylinder to work properly. We have devised a slave cylinder kit
(P/N 716340) that includes all
of the necessary components to fit this bellhousing and to work with your stock Jeep master cylinder.
This bellhousing uses a dowel pin alignment to both the engine and transmission. The bellhousing must be bolted to the transmission before
being installed into the vehicle. The stock Jeep dust shield from a AX15 or NV3550 should be used and the starter must index into this
sheet metal pieces. A new pilot bushing has been supplied and must be installed fully into the stock engine crank.
This pilot bushing is
manufactured out of a "oilite bearings bronze" which must not be assembled with any type of grease.
Reinstall the new or stock clutch components. Install the transmission and bellhousing up to the Jeep engine. Use the stock bolts from
the engine to fasten the bellhousing to the block. Make sure the dowel pins are installed in the block before bolting on the bellhousing. If
your engine requires a flywheel sensor for emissions control, install the flywheel sensor using the stock dowel bolts to obtain the proper
alignment. If you are not going to use the a flywheel sensor but want to cover the access hole, you will need to fabricate a cover using either
a piece of rubber or thin piece of sheet metal. This should be installed before the bellhousing and transmission are installed in the vehicle.
These components are designed to slip together. Do not pull components together with the bolts as damage to the assembly can occur.
When installing the NV3550 and the bellhousing into the vehicle, you will be required to loosen the exhaust from off of the exhaust manifold.
This will allow proper clearance to fit the bellhousing between the body and exhaust system. We also recommend that the transmission
shift tower be removed so that the transmission can fit closer to the floorboard - allowing for an easier clutch alignment to the input shaft
of the transmission. Be sure to cover the shift tower hole in the transmission to avoid debris from entering the transmission.
NOTE: The 1987 Jeep YJ did use a thicker flywheel than the 1988 and 89 models. The new bellhousing will not work
with this thicker flywheel (1.3125"). You can modify the thickness of the flywheel and or the release bearing; how-
ever, we do offer a new flywheel for this 1987 YJ which will also require a new starter.
