I'm stuck because I can't get the pully off. I tried with a breaker bar(up against one of the two cam pullys) and a ratchet. no luck, busted about 6 teeth from the timing belt. Any suggestions would be great. I will be checking off and on for details. Thanks in advance. By the way, this is an EXCELLENT site!

use a harmonic balancer puller...looks like a chicken foot and u put 3 6mm? bolts thru it with washers and tighten it down and it presses it off after you have remove the crank bolt...

I assume because you said ratchet in your problem description, that you're having issues removing the bolt. There are a couple of ways to get it off. Try a big breaker bar, and have the transmission in gear to try to break it loose. Otherwise (VERY carefully) prop the breaker bar up against part of the frame, remove the coil wire from the distributor, and bump the starter. That'll break the bolt loose real quick.

 

Make sure you've removed the coil wire, as you don't want the truck firing up with the breaker bar on the bolt.....could get ugly real quick.

Removing the main bolt can also be accomplished by: Remove the 2 bolts for the starter, slide it forward about 1", use a big flat tip screwdriver in the teeth of the flywheel to lock it into position and then break the torque on the bolt...

How did you take teeth off the belt if the balancer is still on? I hope you didn't bend any valves by accidentally rotating the crank while the cams were stopped...

[lightyaj]

i'm not sure if i bent any valves. will it sound different or even start. anyways i had it running and about a week later it went out on me. had to tow it home. took it apart again and the bolt to the tensioner snapped off. i extracted the bolt off and replaced it. it's running again. just did that about four days ago. this time it was a lot easier.

[unccpathfinder]

and u didnt bend any valves when u broke the tensioner? that would be friggin amazing and lucky...if u bend valves it can possibly still run and idle pretty steady depending on what you bent i bent #1 and #3 on my 87 and we set up the timing so i could drive it across town and do a top end job...but it had NO power at all...
