My engine number is 10586936...
(Darn phone won't upload pics to the forum done a recent update)..
Seems to show it might be an October '24 engine, yet it has cast iron pistons, which I thought I read were introduced in May of that year. No biggie really... it is what it is.... just wonder'n...
No real indication any work was done on The engine... but really... how am I to tell? Maybe cast iron were indeed put in on a rebuild.
All Model Ts were built with cast iron pistons.
I thought that the very last Ts with X rods (as opposed to H shaped cross section) had steel pistons.
Ford Service Bulletin of May 1920 says that new lighter pistons have been introduced. A change in oil groove was reported in April 1922.
The above were all cast iron before and after these changes.
Ahh... so the 'lighter piston weren't aluminum... but still cast iron?
Correct. Ford's first use of aluminum pistons came with the introduction of the model A.
This earlier post shows the 'steel' piston Ford used for later production after the Model T car mfg. stopped. These pistons were for motors built after the T died. The piston are scrap steel and welded, perhaps during war years? Maybe just a short while.
And here is where I posted the late 'X'-rod and lightweight iron piston used in the last month in 1927 of T production.
Interesting reading!! Thanks, all!
Just made my day. Learned something new. The phrase "new lighter pistons" can, and probably often is, misunderstood for being aluminum. Thanks guys!
