Basic Timing
« on: April 19, 2013, 03:40:39 PM »
Need some help for the weekend guys...
I am ready for a first start of my rebuilt engine but I am having a problem getting the initial timing set. Walcks has a great video on their web site titled Distrubitor (sorry I am not computer literate enough to copy the web address) which gives a video instruction on aligning the disrtubitor and setting the plug wires.
 My question is that once he (Carl) has determined that the #1 piston is at the top of the compression stroke he points to the non-contact end of the rotor button and says that is where your #1 plug wire goes. I am confused by that, wouldn't the #1 plug wire go at the contact point of the rotor button? In the case of this video at 6 o clock?

Sorry Carl Walck, I love your parts, service, advice and videos ... I am not questioning your Willy's Jeep knowledge... Just need further explanation.

I will have to go and check Carl's video but convention says when the number one cylinder is on the compression stroke, (NOT THE EXHAUST STROKE!!) the distributor rotor contact should be at the number one plug contact of the distributor cap.

OK, I see what is going on in the video. Unfortunately Carl's jeep refused to stop turning at number one compression stroke and it kept turning over all the way to the number 4 compression stroke. Carl explains that when the rotor pointed at 11 oclock he had air coming out past his finger which was stuck in the number one spark plug hole. Then he tells you to put your number one spark plug wire in the cap at the 11 O clock position.

Also you really want it at number one at the tdc of the compression stroke, when the piston is all the way up. If you have the rotor pointing at number one on the cap, and the points about to open, you should be just about runnable. I normally crank while rotating the distributor a bit either direction for my first start as I am too lazy to get timing exactly on.

In the tech faq section......If you would like to add a link to Carl's timing method to that post feel free.

It already contains a link to Sean's Geico method of timing.

I was  just about to post that same link but F Bill beat me to it.  :)
Don't forget to prime your oil pump.
Good luck and Good Jeepin

whats the best way to prime the oil pump, seems I heard or saw somewhere that someone used a grease gun and pumped in one of the valve ports?

Standard technique is to pack it with prelube of some sort or Vaseline. If it is already installed, you can pump the oil galleys full using a grease gun plumbed into the oil gage line or the front oil galley plug.

Hopefully you have checked end clearance on your pump, and also pulled the cover off the oil pickup screen and got that spotless.

I filled the oil filter then pulled the top hose from the filter and pumped a quart back thru the hose. Here's a pic of my F head motor. I put in a rebuilt shortblock this winter. After starting and making sure there was oil pressure, I let it idle about 15 minutes then shut it off and checked for leaks. (did have a small coolant around the water pump which went away after retightening the bolts) I ran the motor another 1/2 hour, varying the RPMs with the dash throttle. I then put about 25miles on the Jeep and readjusted the valves. I'll probably change oil and filter in another 25 miles.

One other thing if it's not to late, make sure the marks on your timing cover are sharp and put a dot of white paint on the pulley notch. It's alot easier to do when the engines on a stand or the radiator and grill are off.
I learnt dis da hard way ;)

Success! Bill the link you posted above to Sean's timing flow chart worked great. My engine started right up and ran like a champ. My wife does not quite understand my excitement but I'm sure all of you do! All the vitals were perfect, oil 40-50lbs, temp held steady at 140, and generator output (with no load) was dead center. Best of all not a leak to be found. RyanM is making a roadtrip soon, I'll get him to post a video if I cannot figure it out by then.

Hoo-ray! I can't wait to see it. Bolt on a couple milk crate seats and you can chauffeur the wife to an ice cream date tonight.

I am curious about the 140* temps. Mine runs at about 180 and I think most others do too. Is it just a matter of a different thermostat? Is it better or worse to run cooler?

Ryan no thermostat in it yet plus a new radiator and water pump, maybe that's why it runs at 140?

Lack of thermostat would always make it run too cool, unless the temp was over 100 degrees.  Congratulations!!
