After installation of the retainer, the piston pin must be checked for free rotation. If the piston pin retainer is not installed correctly, the piston pin may not rotate smoothly. Failure to check the rotation could cause a seizure of the pin joint.
Adaptable To: The 214-6073 Retainer is cancelled and replaced by the new 253-1238 Pin Retainer in the 223-6362 Piston and Rod Gp and the 223-6363 Piston and Rod Gp. The 253-1238 Pin Retainer is adaptable to all of the 3500 Engines that are listed above.
