A few days ago, my timing belt broke going down the road. kille dthe engine and started coasting. I didnt know how to change a timing belt, but i do all the work on my 94 ranger myself. Im no mechanic, but i have fixed anything that goes wrong with my truck. I got the truck hme and took off everything needed to get the timing belt off...(fan, shroud, drive belt, harmonical balancer pully, and belt cover) then i got to the Here is the advice, and it WOERKED!
-to get the nut off the crankshaft, put the transmission into 5TH
gear. apply parking break, and have someone to apply regular brakes (if no assistant available, block tires good), I think the nut on mine was a 22 mm, but im not sure. Then take a breaker bar or a regular rachet with a pipe over the end for more leverage. You need all the leverage you can get. I used a breaker bar with the 22mm on it. Stand on the passener side near front fender and with the bearker bar on the nut, have the bar over to the driver side as far as you can then pull on it as hard as you can!, mine started coming loose, then swoosh, it broke free, no problem! email me at email@example.com
if you used this information and it worked. goodluck!
