Standard Pistons as Spares for A.M.C. Engines.

Hitherto it has been necessary for Dealers to stock a complete range of Standard Pistons bearing the following codes:-

T = +.001"   B = +.00025"
H = +00075"   V = +.0005"
O = +.0005"   S = +.0075"
A = +.00025"   X = +.001"
M =  Mean Size.   R = +.00125"

All these variations were required to enable pistons to be mated with the appropriately coded cylinders, and to obviate the necessity to stock this large range the number of codes have now been reduced to four as follows:-

M = Mean Size   S =  -.00075"
H = +.00075" R =  -.0015"

Under this new arrangement four different codes of Standard Pistons only need to be stocked to cover all eventualities as detailed:-

Pistons graded M fit Cylinders graded M, A & O.
Pistons graded M fit Cylinders graded H & T.
Pistons graded M fit Cylinders graded S, V & R.
Pistons graded M fit Cylinders graded X & B.

It is emphasised that the foregoing refers to STANDARD BORE SIZES ONLY and not to REBORES.
