The Ranger got home on the flatbed yesterday. After 197,000 miles the timing belt failed not sure if it was original. I bought the truck with 120,000 miles on it. This is a non interference motor so I was a little laxed on maintenance ( I thought this truck would die a year ago!). Anyways I got into disassembly by taking the upper radiator hose, ac compressor, timing belt cover, and power steering bracket off. Before I did this I took out one of the number one spark plugs and put the motor at top dead center. Next I have to remove the crank pulley and install the new belt. See pics below.

Cover off and moving onto the crank pulley. More to follow.

Back on the timing belt.

Used a puller to remove the crank pulley. I used a breaker bar and turned the engine over to loosen the crank bolt. Not enough room to get an impact wrench in there without removing the radiator.

crank pulley out.

After the old belt was removed I checked to see that I was at TDC and then lined up the cam and oil pump sprockets with their marks. Then I loosened the timing belt tensioner and installed the new timing belt. Then I rotated the crank two full revolutions and checked the marks again. I was off by a little on the crank pulley so I had to remove and reinstall the belt again. Another two revolutions and I was right on the marks. I used a large pry bar to carefully retract the timing belt tensioner pulley. There is a special tool for this.

new timing belt installed. Now I just did the reassembly. Truck is running like a champ again. Hopefully the truck will last 250,000 miles
