SCOUT T18-T19-T98 4 SPEED TRANSMISSION

TO CHEVY & BUICK ENGINES

INSTALLATION INSTRUCTIONS:

This kit is for adapting all of the Scout 4 speed transmissions that are equipped with the long input shaft. This kit is
not compatible with the small 1" spline input shafts. The extra long adapter plate will provide a very simple installation
since no transmission disassembly will be required. The original transmission can remain in the stock location on most
conversions. The special bearing retainer and release bearing collar are necessary to clear the large 1-1/4"-10 clutch
splines. The original clutch disc can be retained when used with an 11" Chevy pressure plate. If a new disc or rebuilt
clutch disc is going to be used, then you must make sure that the flywheel and pressure plate will be compatible. We
have experienced a few installations that required the flywheel to be recessed .030/.060 depth. Make sure that when
assembling the transmission to the new bellhousing, that the tip of the Scout input shaft does not bottom out into the
engine crank. You must verify proper pilot bushing contact with your transmission tip. Make sure that the release
bearing collar is greased on the inside groove to provide a smooth clutch operation. Most Scouts are equipped with
mechanical linkage that will need to be modified for use with the new V8 engine.

1. Remove the front bearing retainer from the transmission and cut it off approximately 2-1/2" from the large flange
face. This cut can be done with a hacksaw and you must make sure that it does not protrude into the new retainer.
Install the retainer back onto the transmission.

2. Slide the adapter onto the transmission and make sure the 4 transmission studs protrude through he adapter plate.
The adapter must fit over the stock retainer in order to provide proper alignment.

3. Install the 4 nuts onto the studs.

4. Bolt the new retainer to the front of the adapter using the 4 new bolts. The bolt heads will protrude beyond the
outside diameter of the retainer and you must grind the heads slightly in order to have them enter into the bellhousing.

(NOTE: The A/A bearing retainer will only work with Chevy bellhousing index diameter 4.686".)

5. Install the new pilot bushing into the engine crank.

6. In order for the clutch to work properly, we recommend that an 11" pressure plate be used with a 168 tooth flywheel
be used along with a Centerforce pressure plate No. CF165473S. These parts are compatible with your original
clutch disc and should not be substituted with any other items.

7. Using the stock Chevrolet throw-out arm that was provided with the kit, you will need to modify the opening in
order for the fit into the new release bearing collar. This can be done with a small grinder and hacksaw.

8. The new release bearing and collar are already pre-assembled and pressed together. The inside groove of the collar
has been lubricated with some good grease.

9. With the bearing collar, throw-out arm, clutch disc and pilot bushing all into position, slide the transmission into
the Chevy bellhousing.

10. The release lever must have end play in order to operate properly. If too much end play, then you have done
something incorrect. If no end play is present, then the clutch may need to be changed. Sometimes an adjustable
ball pivot inside the bellhousing will cause these problems.

11 . Bolt the adapter to the bellhousing using new bolts provided.

CAUTION: Make sure that the tip of the input shaft properly engages into the new pilot bushing and does

not bottom out into the engine crank.
