Sure. I've done it lots of times without issue and have got the 'easy way' down pat. That said, if you mess up your engine trying to follow my instructions, YOU are the one who messed up your engine. I had nothing to do with it...Rotate crank to TDC and make sure pump is set for #1 (sprocket hole lines up with the hole in the bracket). Make a very visible paint mark on one of the cam sprocket teeth and mark the timing belt backing plate right behind it. Loosen the tensioner and rotate it to the minimum tension position (you can tighten the nut slightly to hold it there). Rotate the crank CCW whil pushing down on the belt between the pump and the cam. When it is taut between the cam, tensioner and crank then you can stop rotating backwards. You just moved all of the belt slack to the pump sprocket area and hopefully rotated backwards enough to be between camplate ramps with the pump. Now slide the belt almost off the pump sprocket so that it is just ever so slightly still on. Put a wrench on the pump sprocket nut and rotate the sprocket the direction you want to go while gently moving the belt slightly to let it go just one tooth. Slip the belt back on. Rotate the crank back to TDC while again pushing down between the cam, but more gently this time. You basically push down so that the belt doesn't jump at the pump again before the slack is all at the tensioner. Tighten the tensioner back to where it was, make sure the reference marks on the cam sprocket and shield line up when the crank is at TDC, rotate the crank two full revolutions by hand. Enjoy the new range of motion for timing the pump.
Put a piece of cardboard between the belt and gear and it will probably jump a tooth when you roll the engine over by hand. Make sure you have the tools to fix it if things go wrong before attempting.
