C123 Sleeves

Tom Windsor · Jul 25, 2008

Ok, Henry in NC, has given me a worn out sleeve that came out of an A Farmall. It matches the sleeves that I have. Does this narrow down the selection?????????????? You mentioned that the c123 had several variations with different sleeves??

Just measure the seal land on the outside of the sleeve. There are only 2 options, 3 5/16" or 3 7/16".

The 354 898 R1(through 4) block has longer sleeves than the rest of the C123s. I might have one of those laying around if you need to see it.

Correction, there are at least 3, maybe 4 different C-123 sleeves. Blocks 6342 DH and 251069 R1 may take the same sleeve, block 354898 R1 and R2 are different and 366204 R1 used in 130 and 230 are different again. 367825 R1 & R2 used in 140 and 240 may be same as 366204 R1, not sure. I am certain sleeves from 130, 230, 140 and 240 will not fit any pre 1956 block.
