Procedure

This procedure applies to all General Motors 5.7 Vortec style engines on FX12 model Flogistix skids that are currently in service in the Field, Test Loop, at a Repair Shop, or in Storage Yards. Flogistix Service Technicians will install the complete shaft and washer assembly as outlined in this procedure.

GM 5.7 Stub Shaft installation procedure

When installing the Stub Shaft for use on FX12 model skids with the GM 5.7 engine, it must have the centering washer installed prior to bolting on the stub shaft onto the engine balancer.

The correct stub shaft is NetSuite part #011-036-057 and will have two 3/8" key ways in the shaft opposite of each other.

Stub Shaft Installation:

1. Remove existing Harmonic Balancer Bolt and Washer from the end of the engine crankshaft.

2. The Bolt will be reused, the existing flat washer will not be reused.

Centering washer will look like the examples shown below. The radius of the extended center of the washer fits against the dimpled inner hole of the factory GM crank pulley. The outside diameter of the washer is precision cut to fit the recess of the stub shaft. These two points of contact are the alignment mechanism for the shaft. The three bolts that secure the shaft flange against the pulley do not provide any alignment.

3. Install the existing bolt in the new centering washer that comes with the Stub shaft to used - NetSuite part# 011-036-057 (as shown in the photo example below)

4. Install the Bolt and new centering washer onto the engine crankshaft.

5. Tighten crankshaft bolt and torque to 70 lb ft

6. Install Stub Shaft onto the crankshaft making sure stub shaft fits over the centering washer. (as shown in the example photo below)

7. Install the three (3) bolts holding the stub shaft to the harmonic balancer

8. Tighten the three bolts evenly by hand making sure the stub shaft is mated evenly in the crankshaft harmonic balancer.

9. Snug the three bolts using a wrench, then tighten and torque the bolts to 43 lb ft

10. When completely assembled it should look like the example shown below
