Set of 16 rings for four cylinder International model 300 or model 350 with all 3/32" compression" ring grooves and with 1/4" oil grooves.  This set contains 12 compression rings and 4 oil rings.   Check your pistons to see if you need standard 3 5/8" diameter over size before you order.    There are three compression rings and one oil ring on each piston.    Your cylinder bore must be 3 5/8" and not 3 9/16" for these to fit.    

Please check the ring groove with a drill bit.   A 3/32" drill bit will just go down into the compression grooves and a 1/4" diameter drill bit will just fit the oil grooves.    Be sure to check your bore diameter and see before ordering so you can choose the correct rings for your tractor.   The earlier C169 engine in the 300 used 3 9/16" diameter rings from the factory.    I have the 3 9/16" rings here if you need them.  There was an over bore kit available in 3 5/8" that these rings are correct for.   The C175 should be 3 5/8" from the factory.

This first quality made in USA Piston Ring set for 4 cylinder engines includes piston rings for four cylinders.    These rings are used in the 3 5/8" bore row crop tricycle McCormick Deering Farmall configuration as well as the utility model and the U-175 power unit. 

This set fits the same as the Hastings set # 2C7677 at 3 5/8" bore diameter.   This set uses cast iron compression rings for a fast break in time and minimal cylinder wear.

Be sure to check both your bore diameter and ring widths in your ring pack before ordering.   The easiest way to measure the bore diameter is to measure the piston at the skirt end at right angles to the wrist pin.  It should read a few thousandths less than 3 5/8".


If the bore diameter is 3 5/8" this is the correct set.
If your pistons are stamped on the top with the IHC part number 374299R1 these rings are correct.

 We also have piston rings available for most any application, car, truck, tractor, moped, scooter, cycle, modern or antique
