Use a hacksaw or cut-off tool to shorten the heater valve extension pipe. Shorten the pipe from 6" to a length of about 1.75" inches. Apply thread sealer or Teflon tape to the threads of the heater valve extension pipe. Then reinstall the heater valve extension pipe. Figure 12. Figure 12 14.

The generator hardware will not be reused. Figure 13. Part # 150-128 -3- Modified 04/17 Installation Instructions 17. Use two 7/16" combination wrenches to loosen the six fan hub extension retaining bolts. Use a 1-1/8" socket to break the crank bolt loose. Rotate the crank until the timing mark on the crank pulley lines up with the timing cover pointer. Remove the crank pulley bolt, the fan hub extension, the crank hub pulley and the two plates that make up the crank pulley. It is critical that you align the timing mark with the pulley before you remove the pulley. If you do not align the marks you may have trouble setting your timing when this install is complete. Figure 17. Figure 14 Figure 17 Figure 14 cont. 15. Use a strap wrench and a 3/4" combination wrench to remove the water pump pulley nut. Use a pulley puller if necessary. Then use a 9/16" socket and a 3" extension to remove the water pump mounting nuts. 16. Clean the gasket surfaces. Install a new water pump gasket and the provided water pump from the kit. Install the new water pump pulley, securing it into place with locknut that comes with the pump. Figure 16. Figure 16 Part # 150-128 -4- Modified 04/17 Installation Instructions 18. Install the six bolts through the rear side of the crank 19. Reinstall the fan hub extension using the provided pulley. Slide the crank hub pulley over the bolts and nuts and lock washers. Torque the nuts to 10 ft-lbs. into the recess on the front side of the crank pulley. Then install and torque the crank pulley bolt. Slide the crank pulley/crank hub assembly over the end of the crank shaft. Figure 18. 20. Bolt the tensioner plate assembly to the engine. NOTE: The timing tab will have to be bent as For the 5/16" upper bolt, there will be the bolt, a necessary to clear the crank pulley. You should lock washer, a flat washer, the tensioner plate and a try to have at least 1/8" of clearance between the washer on the back side of the idler plate followed timing tab and the crank pulley. Make sure the by the water pump housing. For the 7/16" lower timing mark on the pulley is aligned with the tab bolt, there will the bolt, then a flat washer, then the on the timing cover. If not, remove the pulley from tensioner plate, the tensioner plate standoff (tall the hub and re-clock it so that it is. Again, this is spacer), then the engine plate, a flat washer, a lock critical for setting ignition timing. washer and a nut. Torque the 5/16" upper bolt to 17 ft-lbs. Torque the 7/16" lower bolt to 55 ft-lbs. Figure 20. Figure 18 Figure 20 Part # 150-128 -5- Modified 04/17 Installation Instructions 21. Some kits will come with the 4-rib serpentine pulley installed on the alternator. If yours is installed, skip this step. Loosen the 7/8" or 22mm nut on the provided alternator. Install the provided alternator fan and alternator pulley onto the provided alternator. Then install the alternator nut. Tighten the nut to 45 ft-lb. You will need to hold the fan from turning while tightening the nut. We have had good luck holding the fan with a carefully positioned rag and using an impact to tighten the pulley.
