New Front Suspension Group Uses Stronger Rod Assembly{7201}
Usage:
776 Tractors;
777 Trucks
Description of Change: A new front suspension group is used on 776 Tractors and 777 Trucks. The new group uses a new rod assembly, which is made of stronger material. This will increase the strength of the front suspension on the machine.
Adaptable As: The new 4T3235 Suspension Group is a direct replacement for the former 3G683 Suspension Group. Also, the new 4T4757 Rod Assembly is a direct replacement for the former 8J8884 Rod Assembly. The former 3G683 Suspension Group and the former 8J8884 Rod Assembly are both canceled. Installation of a new 4T4757 Rod Assembly in a former 3G683 Suspension Group will make the group basically the same as the new 4T3235 Suspension Group.
