Camshaft to crankshaft timing

Post by Heinz »

Hello in the forum!
Has anyone an idea, why on the T-214 engine the camshaft is set to cyl. nr. 6 ? When I replaced the front crankshaft oil seal I recognized, that arrangement.
When the markings on the timing gears are aligned, nr. 6 cylinder is on compression - up to now, most other (non-Dodge engines) I have seen nr. 1 cylinder is on compression when timing markings are aligned ?

There is an answer to that - it is the easiest one to check with the proper ( Wilson?) gauge tool. there is a small threaded plug in the head over number 6 which is removed and then you can check it is top dead centre very accurately.

Chrysler engines baryon the front timing marks. I had an engine where the timing arrow was about ten o'clock on the timing cover - I can only assume it was for a cabover or something like that. I think TDC on compression stroke is standard.

Hello Gordon_M and thank you for your quick reply.
I am just surprised that the T-214 engine is set to cyl. nr. 6 when timing marks are aligned instead of alignment to cyl.1. I have the side covers off , so I can see the camshaft anyway and also the timing cover is off to see the timing marks.

G,Day Heinze .Who ever assembled your engine has assembled it wrong .Dodge TM 10 -1531 page Engine 01-35 engine specifications. States that the firing order is 1-5-3-6-2-4 . Most ,if not all 6 cylinder motor,s are 1-5-3-6-2-4 . Hope this helps . Ray

Hello Ray!
The firing order is clear to me, what makes me wondering is the fact, that when the marks for the camshaft timing are aligned properly, cyl. 6 is under compression - this has not really something to do with the firing order. Up to now, I have only seen engines where the camshaft is marked to cyl. 1 - and not to cyl. 6;

when assembling the engine I suppose it doesn't matter as long as marks are lined up. maybe they used 6 because that is where the plug is to put rod in so you can get 1 and 6 to TDC, when six is at top of stroke so is 1. I have never seen another engine that way either. maybe they didn't want to put the access plug over number 1 because the water jacket may have been then too small? all just guesses tho

@Kaegi:
So it seems to be standard on Dodge T214-engines that the camshaft timing is set to cyl. 6 in compression? I have not seen any other Dodge engine to be able to compare and the manual does not really talk about it.
I only recognized that setup on my Dodge, when I replaced the front oil seal of the crankshaft and was wondering. The engine is running fine so far.

I think all the flathead Mopar's must be set up that way. i think it does mention in on one of the manuals.

Just to throw another log on the fire, at one time some people numbered the cylinders from the firewall forward, so they would all the cylinder next to the firewall #1

G,Day all . Let,s not try to rewrite history . But all Dodge motor and most others were timed 1,5,3,6,2,4 .The dodge manual spacificaly says this is the firing ORDER . I would suggest that you take of the head ,and timing chain ,turn the crank until the no 1 cylinder piston is at tdc . Then turn cam shaft until Both inlet and exhaust are closed. . The marks on the cam and crank should be lined up . Therefore No1 cylinder will fire .Not rocket science .As i said before . Engine assembled wrong . Ray .

Hello Ray!

Thanks for your reply.

I am not talking about the ignition timing / adjustment, I am talking about camshaft to crankshaft alignment:

First you align the camshaft to the crankshaft - according to the marks on the timing chain gears - and if I align these marks according to the manual, cyl. nr. 6 is on compression on my Dodge, and that is what made me wonder - there seems not to be any other way for assembling if I follow the two marks on the timing chain gears.

However, I did not dismentle the engine, I just looked at the marks when I changed the front crankshaft oil seal.

The firing order is given by the camshaft anyway and cannot be changed. Only the ignition timing can be changed by rotating the distributor - but that is not the question.

G,Day Heinz .It would appear that i was wrong . I was thinking firing order .not timing . I watched a bloke on utube time a dodge 6 . He used a piece of steel rod to check out when the number 6 cylinder was at tdc . He was checking the opening /clossing of the point on the dissy .A Classic case of putting mouth into gear, before my brain .Ray
