Model T Ford Forum: Forum 2014: Main bearing caps
Top of pagePrevious messageNext messageBottom of page Link to this message  By Val Soupios on Monday, December 01, 2014 - 08:23 pm:

Are the main bearing caps the same throughout production? If not, are they all interchangeable? The machine shop lost the bearing caps to my '25 motor that was in for a rebuild and I am wondering if I can use the caps from a junk '13 block instead. I always assumed they were all the same but want to be sure before I go ahead and have them babbitted.

They will fit, but! 1913 would be Dodge Brothers caps and are re-babbitted a little different to the Ford ones, your shop may not have the mold to do them.

is there a junk 13 block?

Clayton, not any more. The center web disintegrated and the rear of the block was punched out when the crank let go. The pieces went for scrap but fortunately I had a replacement block cast 7/11/13 with no serial number and I stamped the old serial number on it so, technically I guess, it lives on. After I did that it occurred to me that in the future if someone compared the casting date with the serial number it would create an inconsistency as blocks were generally installed in cars within a certain time span after casting.

If the date that corresponds with the number you stamped is later than the casting date, I wouldn't worry about it. I seem to recall some earlier discussion that the time between block casting and assembly could vary widely. :-)
