New 355-5668 Travel Motor Gp Adaptable To: If the bores of the travel motors are worn, do not reuse the body. Use a new 193-7901 Body and a new actuator piston. A new 345-3744 Actuator Piston is now used in the travel motor. The new piston replaces the former 196-4987 Actuator Piston. The current 189-3189 Seal Ring will not be used with the new actuator piston. The changes were effective with the new 355-5668 Travel Motor Gp starting with serial number PE10001. The new Travel Motor Gp replaces the former 271-6376 Travel Motor Gp or 190-5970 Piston Motor Gp.
