7. NV4500 Bellhousing & Clutch Info

NV4500 Bellhousing Adapters:

If you are considering a NV4500, we offer conversion bellhousings for these applications.  The bellhousing bolt pattern changed on the Chevy NV4500 transmission.  To install a NV4500 having a mechanical or hydraulic linkage, you have a few options.  The bellhousings we manufacture offer brackets to retain both these linkages.  Furthermore, the late model stock GM NV4500 bellhousing can be used.  This bellhousing is only offered for hydraulic applications and should only be used when replacing a late model Chevy Getrag transmission. 

                                                   PN712577 -          Chevy NV4500 (1992-95 transmissions) to Chevy block, full bellhousing

                                                   PN712576 -          Chevy NV4500 (1996 & up transmissions) to Chevy block, full bellhousing

                                                  PN712550            Dodge NV4500 to Chevy bellhousing 5.125” index, adapter plate

COMPLETE NV4500 KITS FOR CHEVY TRUCKS:

We distribute complete kits for the NV4500 transmission.  These assemblies consist of a new transfer case adapter, transfer case linkage (when necessary), crossmember mount, bellhousing or bellhousing adapter plate, and shifter handle.  A complete transmission package from Advance Adapters is a cost effective way to order.  We offer rebuilt NV4500 transmissions which are the only units available today.  The GM 4WD NV4500 can be purchased under PN26-0007R.

CLUTCH LINKAGE & COMPONENTS JEEPS:

 

Jeep has used both hydraulic and mechanical clutch linkages over the years.  The NV4500 bellhousing for the Jeep use the clutches below and then have a few options linkages:

Chevy engines:                PNLC165473S        Luk 11” low profile pressure plate & disc

                                         PNCF165473S        Centerforce 11” low profile pressure plate

                                         PN383735                Centerforce 11” clutch disc

 

Jeeps 1941-1972 (Hydraulic linkage) - Although these year Jeeps never came with this type of linkage, we have designed a new dual pedal and master cylinder assembly to upgrade your vehicle to a hydraulic linkage.  These components cannot be used on vehicles with disc brakes.

                PN716117 -          Dual Swing Pedals             PN716116 -          Slave Cylinder Kit

                PN716118 -          Dual Master Cylinder          PN716287 -          Slave Cylinder Bracket (GM block only)

 Jeeps 1972-1986 (Mechanical) - These Jeeps use the same type of clutch torque tube as the earlier models, except the torque tube pivots off the bellhousing instead of the transfer case.  This linkage uses a ball design pivot bracket that bolts to the stock bellhousing.  When using one of our Chevy conversion bellhousings, the stock bracket can be retained.  If you are using a GM bellhousing, we offer PN716638 which will provide you with an adjustable pivot location.  If you would like to upgrade your clutch linkage, we offer a chain-operated clutch linkage.  This kit is mounted to the original push rod that extends out of the firewall. (PN716639)

 Jeeps 1980-1986 (Hydraulic linkage) - Jeep first started using a hydraulic linkage in the 1980-82 CJ7s with the 151 Iron Duke engine.  This slave cylinder bolts to the bellhousing using the same two holes as the mechanical linkage ball pivot bracket.  If you are using one of our Chevy conversion bellhousings, this slave cylinder can easily be installed.  If you wish to change to a hydraulic linkage, replacing the mechanical linkage, 1980-86 Jeeps had provisions to bolt a stock Jeep master cylinder to the firewall (Jeep master cylinder No. J5359822).  We offer the stock slave cylinder assembly to work for this application (PN716331).

 Jeeps 1987-1991 (Hydraulic linkage) New Engine & Transmissions Swaps & Transmission Retrofits:

When you are installing a new drivetrain using one of our full conversion bellhousings, we offer a slave cylinder that bolts directly to our bellhousing.  This Jeep Iron Duke slave cylinder works well with the 1987 to 1991 master cylinder (1-1/16” bore).  This slave cylinder is PN716331  and  fits both the GM and Jeep conversion bellhousing we manufacture.

 Jeeps 1992-2006 (Hydraulic linkage) New Engine & Transmissions Swap Combos:

When you are installing a new drivetrain using one of our full conversion bellhousings, Jeeps 1992 & newer used a master cylinder with a 3/4” cylinder bore.  We offer a slave cylinder bracket that bolts to our bellhousing and allows the use of a Toyota Land Cruiser slave cylinder. This bellhousing does have the provision to use a Jeep Iron Duke slave cylinder; however, this slave cylinder is marginal when used with this YJ and TJ master cylinder.  The recommended method of using the Land Cruiser slave cylinder would require the following:  PN716288 slave cylinder bracket (A.A. bellhousing), PN716119S TLC slave cylinder, PN716215 slave cylinder fitting, and PN716130H slave cylinder hose.  You will also require a special master cylinder fitting depending on the year of your vehicle.  This assembly only works on our GM conversion bellhousing.  The Jeep bellhousing will need a special bracket to be manufactured.  If you are using a stock Chevy bellhousing, the slave cylinder bracket should be PN716287. 

 

CLUTCH LINKAGE & COMPONENTS TOYOTA L/C: 

Whether you are retaining your stock 3 or 4 speed transmissions or upgrading to a new 4 or 5 speeds, clutch considerations will need to be addressed.  We highly recommend retaining the stock Land Cruiser slave cylinder.  Whether you are using a stock GM or a conversion bellhousing, we offer the brackets to retain this slave cylinder.

                           

                PN716288 -          Conversion bellhousing to Land Cruiser slave cylinder bracket

 

We offer a new Land Cruiser slave cylinder, PN716119.  This slave cylinder has a very short release.  When converting to a V8 engine and using an aftermarket clutch assembly, you play havoc attempting to get your clutch to release properly.  We highly recommend using Centerforce or Luk clutch components.  Centerforce & Luk use a low diaphragm pressure plate that works in conjunction with a large diameter, radius-face bearing.  This combination is proven to work with the Land Cruiser hydraulic release system.

 

Chevy engines:                PNLC165473S        Luk 11” low profile pressure plate & disc

                                         PNCF165473S        Centerforce 11” low profile pressure plate

                                         PN383735                Centerforce 11” clutch disc

                                         PNCF700120           Centerforce 168 tooth flywheel (up to 1985 blocks)

                                         PNCF700160           Centerforce 168 tooth flywheel (1986 & up blocks)

                                         PN716316                Release bearing for stock Chevy transmissions & Land Cruiser 3 spd. transmission

                                         PN716176                Stock GM release arm
