(Clockwise from the front!) With a tight fan belt, the engine should turn. Another method is to put the truck in high gear, and gently roll it forward until #1 rolls up to TDC. BTW, the timing mark comes up twice, once at the top of the compression stroke, and again at TDC on exhaust. One of our guys here spent a couple of weeks figuring that one out! Be sure both valves are closed on #1 when you line up the timing mark! Jerry To add to this, if you have the plugs pulled, you should be able to put your finger over the #1 plug hole and turn the motor over with the fan. When you feel the compression move your finger away from the hole, this is the compression stroke. Continue rotating until the TDC mark is lined up. If you can't find the TDC mark, rotate until no more compression is felt. That will be close enough to set the distributor rotor to point at #1. It otta fire right up from there. | | |
