12. Lift the rod out of the bracket.
13. Lower the spring tube assembly out of the rail assembly.
14. Remove the string from the old spring tube assembly and secure it to the new spring tube assembly.
15. Thread the new spring tube assembly into the rail assembly by raising it with the string.
16. Insert and secure the rod in the bracket. Position the opposing M5 nuts so that the bracket is approximately
halfway up the threaded section of the rod. (Refer to “Figure 5-44 Heater Door Cable Adjustment”.)
17. Using the string, pull the spring tube up until a 2mm hex wrench can be inserted through the inner rail and
spring tube, temporarily securing the spring tube. Check that hex wrench is fully inserted in the hole in the
opposite side of the inner rail.
18. Remove the string.
19. Re-secure the heater door cable end cap by screwing in the setscrew with a 2 mm wrench. Moderate
tightening is correct.
20. Verify that the door cable is securely held in the spring tube by pulling on the cable.
21. Remove the hex wrench that was temporarily securing the spring tube to the inner rail. Allow the spring
tube to hang on the cable.
22. Check that the dog point of the set screw, opposite the hex wrench, is protruding slightly from the spring
tube.
