After looking through the manual and the forum I still couldn't find the answers I wanted so I came up with my own way to put on and tension the timing belt. This method may be slightly controversial but it works. The advantage to this method is that you can put the timing belt on really quickly without fiddling to get it in. The engine turns over just fine but I haven't started it yet to test it out fully. There is up to a max of 15 mm of belt deflection with 10 kg (22 lbs) of pressure so I think the results should be good.
Note: Timing belts are actually Gilmer belts. Gilmer belts do not need much tension if any at all to properly function so it is better to stay on the looser side of the belt than on the tighter side. The only reason to tension these belts is to prevent the teeth from hopping during start-up when the belt goes from 0 RPM to 1500 RPM in about a second. The only thing to keep in mind is the square tooth belts are much more sensitive to tension than round tooth belts. Too much tension on the square tooth style belt can cause the sprockets to eat away the teeth.
Step 1:
With the engine at TDC, install the timing belt with the tensioner removed. Don't forget to count the teeth between the sprocket punch marks. Always remember to put the timing belt on with the arrow facing you.
Step 2:
Slide the tensioner in. Install the two washers and hand tighten the nut. The spring anchor should lean against the oil pump housing.
Step 3:
Using a 5 mm Allen key, turn the tensioner one full revolution clockwise. You will hear it snap into place and the spring anchor will be now pressing against the stud.
Step 4:
Slightly tension the belt by turning the tensioner clockwise by about 100 degrees.
Step 5:
Temporarily tighten the nut and temporarily install the harmonic balancer then turn the engine over at least twice to get it back to TDC. This will allow the timing belt to get comfortable with the sprockets. The marks are no longer going to line up if you only turn the engine over twice. This is normal.
Step 6:
Loosen the tensioner nut again and turn the tensioner counterclockwise to about the 5 o'clock position to set the tension. After the desired tension has been set, tighten the nut again.
Step 7:
Torque down the tensioner nut to about 50 Nm (or 36.9 ft lbs). Always remember the crankshaft sprocket washers for the belt.
