    If you can only loosen the Front Cam Gear Sprockets,
    First remove the belt. Then rotate both sets of cams, so that the cam flats are facing up install the cam hold down tools. Then loosen the cam gears on the front head and undo the lock rings. Set the crank to TDC by aligning the marks. The front cam gears should spin freely. Install the belt, tensioner and pullies. Then remove the rear cam hold down tool.
    Then rotate the crank until the rear cam flats are facing down, I think it is 1 full turn or 360* the front cams should not move, just the gears. Once you have the rear cams set face down, the fronts should be face up, install lock ring and tighten gears back down with the cam gear tool. Remove cam hold down from front and reassemble the motor.

    Just remember what i said as far as If you are only going to loosen
    the 2 Front Cam Sprockets...Bots .....If you do not loosen the Rear Sprockets, the Crank will turn when you pull the pin on actuator throwing the Timing off....The way i solved this, was to take everything back off, and set the crank about 10* to 12* ahead of the timing mark so that when i put it all back on, and released the pin...it tightened up on the belt and turned the crank to the desired mark...with a little measuring and Luck, it landed right on the money. As far as the Grinding sound???? Did you refill the Power Stearing Fluid back up?...kinda what it sounds like from here....Hope this helped...Paul
