Question about 1984 Jeep CJ7
Removed the distributor and lost the position can anyone help to set timing again
I'm going to assume that you have some idea where the rotor was pointing before you took unit out.
Turn the crankshaft by hand 'till you find the small notch on the back edge of the pulley. Mark the notch with white crayon. Turn the crank untill the mark you made lines up with "0" on the scale on the right side (facing engine) at about 2 oclock. (sometimes needs to be cleaned off to read it) You are now either dead on or 180degrees out of phase. (rotor will be pointing directly away from where you think it should be if it is 180 out). If close to original location, make a mark on outside of dist housing, directly below #1 ign wire post. Remove cap and check that rotor is aligned with the mark you made. If it is not, remove distributor part way, till you can feel the drive gear just disengage, then turn rotor towards the reference position. Once positioned, push distributor housing back down into block. If it does not drop down fully, have someone turn the crank by hand two full turns back to reference mark while you push gently down on distributor. when the oil pump shaft engages, dist will drop down.
If you found dist to be 180 out, remove it and turn rotor to proper position, then follow instructions above.
The timing is non adjustable on these engines.(timing is changed by computer) There is a single bolthole in the dist retaining ear (part of dist housing) When checking reference points, always keep this hole lined up with bolt hole in block. Before attempting to start engine, make sure that after everything is bolted down, your reference marks match!
There are several other ways to do this. This is the most simple and safest way. as at no time is the ignition key in the "on" position, while making these adjustments..
Turning the engine with the key "on", even by hand, & even with the timing out of phase can result in "kickback" which can and usually does hurt someone.
