27-0030 : Replacing GM/Chevy Fullsize SM465 4 Speed Manual Transmission & NP205 Combo with GM 32 Spline NV4500

Description

Kit Includes:

1. 1 KIt PN50-0217 NV4500 TO CHEVY NP 205 TRANSFER CASE 10 SPLINE

2. 1 Kit PN712576 NV4500-1996 GM BELLHOUSING ADAPTER KIT

3. 1 Kit PN715534 GM MECH. CLUTCH LINKAGE BRKT.

4. 1 Kit PN716050C NV4500 SHIFT HANDLE ASSY.

This package is for a GM 4WD NV4500 to the GM 10 spline NP205 (1971-85). This application requires the shortening of the NV output shaft to 4.498” in length. When using this kit, we couple to the 31 spline area which is under the harmonic balancer. In order to cut the shaft, you will need to remove the GM tailhousing. The NP205 has a 10 spline male shaft. We manufacture a female coupler that engages the 31 spline transmission to the 10 spline transfer case. We have included a new seal for the adapter housing along with a new sealed bearing for the transfer case for extra protection. This transfer case adapter kit uses two castings to couple the NV4500 to the NP205. These castings have been machined to allow for proper transfer case shift rail clearance. A shifter bracket has been provided to mount the stock NP205 shifter handle; however, you may be required to modify the handle to properly fit up into the cab of the truck.

The bellhousing in this kit bolts directly to the front of the NV4500. Depending on the type of clutch linkage your vehicle has, we offer two brackets to assist you. The kit comes with Part No. 715534, which is a bracket for the mechanical linkage. This bracket provides a pivot point on the bellhousing similar to the pivot found on a stock GM bellhousing. Some mechanical linkages use a pivot point off of the engine block which would remain the same. If your vehicle was equipped with a hydraulic linkage, we also offer a slave cylinder bracket that bolts to our bellhousing, PN715535. This bracket is designed to fit 1985-1991 GM slave cylinders (GM #15615868). You can substituted P/N 715534 with P/N 715535 when ordering this complete kit. The SM465 is 12” long with an adapter housing of 7.250”. The transmission and transfer case adapter length is approximately 19-1/4”. The overall length of the adapter kit is approximately 1” longer than the stock; therefore, driveline modifications may be necessary. The overall assembled length including the bellhousing is 26.250”.

Several adapter kits require you to shorten the existing transmission main shaft while it is still in the transmission case. This is common when a 4WD GM NV4500 is being used. Each instruction sheet gives the exact cut off location.
