The new switch will replace the former switch after slight modifications are made to the electrical connections on the machine harness. The new switch is a different design with major improvements inside for increased reliability. In addition, wire leads and a two contact DT connector increases reliability of the new switch compared to the former switch which used stud and ring terminal connections. Adaptable To: The new 116-9933 Switch Assembly is adaptable to current and former machines using the 7N-4447 Switch Assembly. Use the procedure that follows to adapt the new switch. The 7N-4447 Switch Assembly will no longer be serviced. Future production of current machines will use the 116-9933 Switch Assembly.1. Disconnect and cut off the ring terminals on the machine harness that connect to the 7N-4447 Switch Assembly.2. Attach the 102-8807 Plug Kit and two 8T-8730 Sockets to the machine harness wires. These parts can be found in the 9U-7246 Connector Service Kit. Use a 1U-5804 Crimp Tool to install the new sockets. Special Instruction, SEHS9615, has detailed instructions on servicing DT connectors.3. Remove the old switch and install the new 116-9933 Switch Assembly.4. Connect the newly installed connector to the 116-9933 Switch Assembly connector and secure this to the machine using a 3S-2093 Wire Tie. A 4C-5877 Tool can be used to tighten this wire tie. In some cases, a 4P-8134 Clip may be used to provide a place to tie this connector to the machine. The 4P-8134 Clip has a 10.5 mm (.413 in) diameter hole to be bolted to a machine or engine with the appropriate length bolt. The 4P-7429 Clip which has a 13.5 mm (.531 in) diameter mounting hole is also available. The 4P-8134 Clip or the 4P-7429 Clip, resembles a ladder with multiple places to tie connectors using a 3S-2093 Wire Tie or equivalent.
