Synching a distributor with the timing of an engine

Anonymous-0 · Jun 30, 2014

Besides trial and error is there a logical way to synch a distributor with the timing of an engine. We have a IH Model 101 Selfpropelled combine (six cyclinder) motor. The spark plugs cables were pull off and not put back. As a result trying to put the right wires on the right spark plugs could be problem. Any help would be appreciated

The first thing good to know is THE FIRING ORDER. I"m sure some gents will have it for your engine or it may be on the manifold.

Then get the Number one Cylinder up to TDC on its Compression Power Stroke.

At that time the distributor is installed such that the rotor tip is lined up with the internal cap pick up that connects with the Number One Cylinder (Number One Plug Wire)

Then the next cap tower gets the next cylinders plug wire in succession of the engines firing order.

Make sense??

Trial and error isn't an option. You need to know two simple things, Firing Order, and Top Dead Center. Most IH engines I have ever seen has the words "Firing Order" cast into the engine block, usually near the distributer. Take a good look at yours. Top Dead Center is number 1 cylinder at the top of its stroke with both valves closed(top of the compression stroke). At that point, remove your distributor cap, notice which terminal the rotor is pointing towards, that's where you number 1 sparkplug wire goes. Then, note the correct direction in which the rotor travels, then simply plug in the wires according to your firing order.

the firing order is 153624. dist. rotation is c.clockwise. #1 on dist should be next tower c.clockwise of point wire. ( but not nessesarily). look at bottom of towers and it may even tell you the firing order. as john says get #1 on tdc and compression and see where rotor points and go from there c.c.
firing order should be on the block also under dist.

Good info, many engines have that Firing Order stamped somewhere such as the manifold. That was a six cylinder Firing Order I was thinking but I learned long ago never say never and never say always because the GOTCHA players love to jump out behind the bushes for an ambush if there's one little exception somewhere out there lol

On most engines there is a firing order some place on the block or manifold. Find that first. Next get #1 cylinder on TDC compression stroke if you can then pop the distributor cap off and see where it points as to the nipple on the cap that is #1 Also good to have the cap off when getting to TDC so you know which way the distributor turns

John I agree with you on the gotcha players, but the instructor in the military said that all inline 6 cyl. have the same firing order. 15 too young, 36 too old, 24 just right.

And if you really want to be good, turn the distributer so that the points will be ready to open. The coil fires when the points open.

I agree that most are 153624, But I had a 1950

GMC 6cyl 360 and it was reverse firing order

142635 , that truck got a lot of people in

trouble. BTW it was a road tractor that I

pulled equipment trailer with.

All in line 6 cyl engines that I've worked on fire either 153624 or 426351. It's the only way to make em run smooth is what was explained to me a very long time ago now it seems.

Do as the other guys say. TDC on the #1 AND KNOW WHICH WAY THE DIZY ROTATES! Then put the rest in order.

To all who answered my questions a BIG THANKS.

I would say that is still the same firing order, just backwards.
