  Hi I have a set of 8 Ford conrod bearings, the Number on the Ford box's are C-41A-6215-AS . Can any body tell me what size they are and what motor they are for they look to be the small crank ,they have lock in tabs Thanks for your help Stewart Quertier. New Zealand.

  Those would be for a later engine, and most Ford dealer parts departments should be able to give you the info. Look for numbers on each bearing sh*ll. Too often, boxes contain mixed sizes.

  Hi Supereal thanks for the reply I have checked all the box's and the numbers are all the same 6213 on one half and 6214 on the other half , they also have Ford USA A5 M on them . they measure just under 2 inchs inside . the box is orange and dark blue with Ford on it ,also has Conn rod liners halves standard on it , what year would they before, and when did they stop making the small dia cranks. Thanks Stewart.

  I haven't been able to cross match the number 6215 with any of my references. The group number for rod bearings is 6211. For main bearings, it is 6331. I don't have the specs to prove it, but the orange box leads me to believe that the parts may be for a Ford tractor, rather than a car or truck.

Pilots had different exhaust manifolds; much better design than any Yankee job. They also came equipped with a bypass filter, which I think is the same as early Landrovers. A sealed unit, one needed to replace the entire filter, not just the cartridge.
The crankshaft is very similar to American 21 stud ['36 LB and later], but is drilled with double oil holes for the sh*ll bearings, but has the larger diameter, longer snout that the 24 stud cranks have. Easy enough to shorten up and convert into an American 21 stud block. These Pilot big end sh*lls are unique in as much as they have a flange on one side; they are just like an early [flanged] full floater, cut in half and with locking tabs in each sh*ll. Of course flanged full floaters can run on that crank and the Pilot rods run on the outside of those floaters.
The Canadian sh*ll bearings to suit double drilled crankpins did not have these flanges as the crankpins were narrower; this design was introduced with the 24 stud engines. I have had several sets of these bearings to suit the small journal cranks; the part number was C41A 6215 [then the factory code denoting size]; the large dia locked in bearings have the prefix C49A 6215. Anyone encountering these bearings in an engine can rest assured that you can run the common full floaters #6211 using the same rods and crankshaft [after carefully measuring everything up to ensure exactly what you have].
All pilots ran a 5T camshaft, and I understand they came from the factory with twin pipes, although I have no actual proof of this, just what I've been told by numerous 'knowledgeable' folk.

  So they could be clip in English Ford Pilot bearings the only Pilot big end bearings I have seen had the flanges on the one side, Pilots were sold down here in New Zealand,
