I also can't seem to get the harmonic balancer off. Once the center bolt is out it should slide off right?
It won't slide off, they are pressed on tight.
Well I got this motor that is locked up. The pistons are rusted in the cylinders bad. I was going to try and save the crank and cam but since I can't rotate the crank I can't get the torque converter off and I can't get all the rods off.
Is the motor still in the truck? Have you got the heads off? If not then lay it on it's side and spray about a 1/2 can of PB Blaster in each of the 4 cylinders facing up through the GP holes and let set for 3-4 days, reinstall the GP's and repeat on the other side.
If the heads are off, do the same, meaning fill the cylinders with PB enough to cover the piston.
After a couple of days, have someone try to turn the crank while you bang each piston with a 2x4 and sledge hammer. Do that in the firing order.
Is the TC still hanging on the flex plate or is it a solid fly wheel?
The engine rotates in a clockwise direction as seen from the front of the truck, and for every 1/4 turn of the engine(crank) each next piston will arrive at TDC. So, When the line on the vibration damper is at the 2 oclock position, cylinders 2 and 5 will be at TDC. When the mark is at the 5 oclock position, cylinders 7 and 6 will be at TDC, 8 oclock has cylinders 3 and 8 at TDC, and back to 11oclock, 1 and 4 will be at TDC.
Cylinder numbers are assigned 1,3,5,7 on the left (passenger USA) bank from front of truck to back, and 2,4,6,8 on the driver's side (USA), front to back. Firing order is 1,2,7,3,4,5,6,8.
