PROBLEM
Show/hide table
The existing 4492128/">449-2128 Bushing can seize on certain 416F and 420F Backhoe Loaders. If the existing 4492128/">449-2128 Bushing fails, the hand bucket control can become hard to operate.
In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 16% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
