Hi: Im doing a valve job on my 27 Touring and when I went to put the cam in I noticed My crank pin is vertical at TDC and not horizontal like most of the cranks are. Did Ford drill some of the crank pin holes that way. The engine was running OK but no power, when I tore it down because the cam bearing shells were lose in the block. I have not put the lifters in yet but When #1 is at TDC and I line up the O on crank gear with the O on cam gear my crank pin is vertical. If you draw a line thru the center line of cam thru both O marks and center line of crank they all line up. I did a check of the marks before I tore it down and the crank pin was vertical at TDC then. I had a fiber gear that I have removed and replaced it with a good used "Ford" gear. I think everything is timed right but the crank pin is ????
How are you telling the engine is at TDC?
When the timing marks on the crank and cam gear line up the crank/engine is not at TDC. It looks like normally the crank pin is about 45° when the timing marks are lined up.
Do you have a photo?
Hi: I took some pics today of the crank and time gear positions. I also found some mention of a EE crank on another thread posting. It says Ford made some heavy/stronger cranks labeled EE in late 27. ??? I looked at my crank and it is a EE. Could it be the late 27 EE cranks had the crank pin drilled differently. ?? I also noticed that my rod caps have dippers. They are Ford script. The crank is also Ford script. I believe everything is timed right its just the crank pin that is puzzleing me. I also found in one of my Model T Times a copy of the Ford Service Bulletins for Oct 1919 It list all the genuine Ford trade marks as well as all the counterfeit trade marks for the connecting rods. One of the companies trade marks listed is EE. It appears that EE may have been a "bogus counterfeit part maker", as Henry described them, as early as 1919, and then later made the EE cranks for Ford as a authorized part maker. Only a guess on my part.
Not to say it can't be made to work but the two cranks I have both have the crank gear key 90 degrees to the crank pin hole.
Engine running and timing are critically dependent upon the timing gear key-way, NOT the crank pin. The starting crank handle has four cogs on it. The crank-pin hole can be drilled in two places 90 degrees apart without changing how the crank handle will engage the compression to start the engine.
I do not know that cranks were or were not drilled both ways.
Just a quick observation.
