i have some "mystery" connecting rods to identify ... they are the same dimensions as Model T , EXCEPT for the wrist pin ... the photos will show that detail ... all other dimensions are the same as Model T ...the wristpin is bushed with bronze bushing .750" diameter ...
these may be an aftermarket rod intended for Model T ... the wristpin end would require a floating wristpin with end locks to hold inplace ...not a standard Model T wristpin with clamp bolt ...
forging number is 81008RF also is numbered HF12 ... i have several rods and 1 other is HF11 ... this number is probably a die set identity ...
any help in identification will be appreciated ...

another photo ... missed this one in first post ...

Was there not a stamped steel piston late in production that used a floating wrist pin like the A?

Now I'm not saying it is, (because I've never seen one) but before the part # 3024 rod from 1909 on, was a rod that parts book shows as having no clamp but a bush and wrist pin with a hole at one end + a screw and cotter pin for the piston. Also on that rod was a dipper cap, can't see that on yours but it does look to be a DB style cap.

Must be of the late 27 style. There was a very light steel round dome piston, common to the x rod. That piston pin "Floated" like an A. This must be a pre X rod for those late pistons.

i had thought of the later style rod ... i have only seen the X type with integral oil dipper on the cap ... this cap is of the common type without any dipper ... the big end is drilled and X grooved as would be common with re-conditioned rods ... these are from an obsolete inventory from a closed auto parts store ... thanks for the info. ... i will continue to check in my old parts catalogs and re-builders reference books ... will post any info. i find ...always an optimist...Gene French

Check in service bulletins, I think there was something about the steel piston and rods in them.
Wish some one would print them again, like the MTFCI did. Dan
