Description of Change: Debris may collect on top of the seals of the gas springs. Debris may collect if the spring assembly is placed in the column with the rod end upward. Debris may be pulled into the seal as the gas spring is actuated. The debris may cause the gas spring to lose gas. The debris may cause the spring to lose oil.

Adaptable To: A new spring assembly is available for the steering column gp in certain Backhoe Loaders and Wheel Loaders. The new spring assembly has improved external dust seals that prevent debris from reaching the internal seals. Refer to Table 1 for new part numbers and former part numbers.
