PROBLEM
Show/hide table
| The 2100691/">210-0691 and 2045380/">204-5380 Diagnostic Hoses need to be inspected, and reworked if necessary, on certain 953D and 973D Track-Type Loaders; and on certain D6N and D6K Track-Type Tractors. The existing 2100691/">210-0691 and 2045380/">204-5380 Diagnostic Hoses, if manufactured with supplier batch code QC15845815, can burst causing high pressure hydraulic oil to leak. If the 2100691/">210-0691 and 2045380/">204-5380 Diagnostic Hoses burst, this may, in conjunction with other factors or circumstances, result in a risk of personal injury or death. You will not be charged for the service performed. |
