NV4500 TRANS. TO CUMMINS DIESEL
REPLACING GETRAG 5 SPEED (2WD)
1. 1 712584-BH DODGE NV4500 BELLHOUSING/GETRAG REP.
2. 1 716162 PILOT BUSHING
3. 4 725002 1/2" LOCK WASHERS
4. 4 725010 H.H.C.S 1/2"-13 x 2"
5. 1 NV001 NEW VENTURE INSTRUCTION MANUAL
TRANSMISSION MODIFICATIONS REQUIRED:
Prior to assembly, modification will be required to the front portion of the new NV4500 transmission.
The bearing retainer must be removed from the front of the 5 speed and shortened to a length that is 4.297" long. This can
be done by using a hacksaw or engine lathe. By shortening the bearing retainer, this will prevent any interference with the
hub on the clutch disc. Also, fit the bellhousing up to the back of the Cummins block to check flywheel and clutch assembly
clearance on the inside of the new bellhousing. You may need to grind on the inside of the bellhousing for added clearance
for the ring gear or possibly the clutch housing. A new pilot bushing has been provided for the new transmission. The clutch
must be removed from the flywheel to gain access and to install the new bushing. The clutch should be inspected for wear
or possible replacement, and the flywheel should be checked and possibly be resurfaced.
The bellhousing is designed to retain all the stock clutch components. The stock Dodge
slave cylinder will bolt directly to our new bellhousing.
When assembling the transmission to the new bellhousing,
DO NOT USE the
bolts to draw the bellhousing into its final position. Make sure that the
bellhousing will receive the transmission without any interference problems.
This bellhousing is only compatible with the heavy duty Chrysler NV4500
transmission. This transmission will have the 1-1/4"-10 spline clutch disc that
will be directly interchangeable with the original Getrag components. Note:
The 1999 & newer NV4500 transmissions do not have provisions for the
Getrag speedometer. The ideal trans-
missions for the conversion is a 1994-1997
Dodge Heavy Duty transmission.
Floorboard modifications for the shift lever will be required. There is a 4-1/2"
difference between the Getrag and the NV4500 on the handle location. The hole
in your floorboard will need to be located back on the floor board roughly 4-1/2".
The backup light switch on the NV4500 is different than that of the Getrag
transmission. A new pigtail can be spliced onto the stock wires. The pigtail is
GM# 12085485, or AC Delco # PT107.
