Info on flathead inline sixes
Actually there are two pics of the 226, one from 49, one from 51. There are a couple subtle differences for 51, one is fairly easy to spot, the other not so much, but you can see the difference.
See if you can find the differences, I will check in a few days to see if anyone figured it out.

My 226 runs great but doesn't purr like a kitten. It has a good number of rattles, especially when you get a bit of rpm and load going. I need to drop the pan and check bearing clearances but before a get to serious about that I need to fix what could have been the original source of some of the noise, The harmonic balancer. What's wrong with the balancer is that it is missing and I find myself "parts challenged" working with this engine.
Any ides were I might find one? New, used, a substitute?

I wonder it the harmonic balancer off the 4.9L (300 cid) straight six would fit? Might require some modification. Don't know if V8 balancers work as well as those made for a six, but I believe JEGs.com sells custom balancers and perhaps would be able to supply one with the right size hole or close enough that a modest amount of honing would make it fit. I wouldn't drive it anymore without the balancer as it sounds like it will tear up all the bearings.

You may be correct about other Ford six balancers working. I had hoped that someone may have given it a try. From what I recall, most of the balancers in JEG's and other similar catalogs are designed for small block chevy's. The chances of these working with an old ford and having bolt hoes that match with the pulley are probably not to good.
This brings me to another problem. No pulley. From what I understand from reading the shop manual, there were to stamped steel versions of the balancer used through 1950. From the pictures, it appears that the pulley bolts to the balancer and could be used with a different balancer. What is on mine appears to be a malleable iron balancer used in 1951 (minus the balancer ring). It appears that with this version the pulley and balancer are a single unit. I can't just use the wide pulley from it.
Your advice about not driving it until it is fixed is probably well taken. I've had the truck about 3 months and when I do drive it I'm real easy on it. Before I got the truck, however, it probably ran for years without the balancer. Not good!
Soooo... Let me ask again, Does anyone know were I can find one? Got an extra one in your parts pile that you would part with? Would be greatly appreciated.
Thanks,

OK, I went through it and the only other photos all appear to be the V8. They are hard to see, but I find four plug wires going to one side, the intake manifold tubes above the engine, or the visible head on a slant.

One picture is of a 51 flathead 6 while the other is a 8 cyclinder. Notice the radiator and the hoses coming from it. Two hoses....thats a flathead 8. The 6 head is a good picture although that is a heavy duty model. The red color is typical for that year. jim

Good point. I looked again last night and the two hoses are a dead giveaway. By the way, when you say the one flathead photo is a heavy duty, do you mean the 226 cid H series ('48 or newer) vs the G series ('41-'47) or do you mean a 254 cid M series ('48 or newer)?

If it is a 110 hp then it would be the M series which was used in bigger trucks. The motors look similar, although the cylinder heads in that picture are different from mine (H series) based on the numbers stamped on the top of the cylinder head. Looking at previous pages in the book, the same color of truck etc., it appears they are talking about a F-6 which would mean the M series for sure. This whole topic brings up another subject....does anyone have a baffle connected to their motor..? I don't? jim

OK, sorry, I have been out of town for a few days, but here is some more info on the 226 pictures in the McLaughlin book. There are pictures on both pages 119, and 121, 121 is a 1950, 119, is a 51.
There are three differences in the two sixes, one of which I didnt even notice until reading this thread!! (hint) Actually I just spotted another difference, but I am not sure if it is model year specific or not. Reminder, one of the changes you might not know to look for, if you didnt know it was there.

[updated:LAST EDITED ON 06-Jan-02 AT 03:28 PM (EST)]The weather finally broke for a few hours at least so here are a few engine pictures. (It rained for 34 straight days and my ’49 F1 was never made for it!) If you look close, you can see 8MTH across the head and maybe even my 4 cell 8V battery. I had the manifolds off to remove the heat riser valve which was more of a rattly leak than a help in cold weather. The manifold gasket is three pieces and two intakes are siamesed. It would take some work to split the siameses because the gasket has one hole and there is no mating surface for the split below it, just a narrow web to split the intake flow.
The flathead on p51 of Bunn’s book is a 226. You can see 1HA6050 in the head casting. The engine on p60 is and overhead valve, a 215 or 223.
There are lots of carbs pictured for the different engines. My 254 came with a carb from a 215 or 223. I found an 8MTH carb on the internet and now have to rebuild it. It is a single barrel Holley 897.

Hey nice looking pics of your motor. I like it. It is the same as mine (48) except the color and of course the baffle. Where exactly does you baffle hook up to? Mine doesnt have one and I dont see the need quite frankly. It sounds like you are doing much the same to your manifold as I did to mine. I agree.
NOw....that motor business and the Bunn book. I know it is a 6 cylinder but feel it is a M series. That truck is a F-6 and even though they put both H and M series in the large trucks.....it sure wouldnt make a lot of sense to do so since the M series six provided more power. The M and the H are close in looks....remember, the numbers on top of the cylinder head do not mean that it is a H series motor....only the cylinder type. So both the H and the M could have the same numbers. Does that sound right ??

One way to tell a 254 M engine from a 226 is the oil pan-the 254 had a 7 qt capacity, and a big winged sump, vs the plain square sump of the 226. Of course, i suppose this could have been changed on your truck. I looked at a 254 carb at Vintage Auto parts near Seattle, and it was noticably larger than the stock 226 Holley 847. I put a Holley 5200 progressive 2bbl on mine ( Holley/Weber ) so far, so good.
As far as the differences between the 226's in Mclaughlin's book, the road draft tube has been moved for 51, the vibration damper is different, the timing gear cover is different, and the hardest to find is the 'level-mount' intake manifold on the 51. It compensates for the rearward tilt of the engine as mounted, so the manifolds appear to tilt down towards the front of the engine in a still photo.

Wow Johann5! What a beautiful truck.
JML: The website looks great. I've bookmarked it for a detailed look later.
50F2: No wonder I couldn't find the second flathead six. I was looking in the Bunn book, but you are talking about the McLaughlin book. Which one? I may want to get it.
Speaking of the Bunn book, I found a couple odd things. First, it says on page 69 (Chapter on the '53s) that you could get a flathead six in the Mercury truck, but then on page 105 in the chapter on Mercury trucks, it says all Canadian trucks were V8s. A flathead six in the '53 body style would be extremely rare (and highly desireable), I would think. The second thing, as I am reading the Mercury chapter last night, after less than one and one half pages of text the page ends in mid sentence and the next page is a new chapter. Pages were not left out as the numbering goes consecutively.
Anyway, thanks everyone. This thread has yielded far more than I thought it would and is still going strong. Hmmmm... wonder if we ever could coax Ken to set up a special engine forum for the flathead six?
