Reconditioning a Lifefitness Lifecycle - Page 4

33. This section is required only for the square tail recumbent bikes. The seat locking pin tends to wear and reults in the seat rocking back and forth while using the bike. The seat assembly must be removed from the seat rail in order to rebuild the locking pin mechanism. The first step shown above is to remove the seat bottom from the frame. This requires removing four bolts using a hex wrench.

34. The lifepulse contact electrodes on the seat handles are connected to the control panel by a ribbon cable and a wire harness. The wire harness retaining clips are removed from the bottom of the seat rail and the wire harness is unplugged from the ribbon cable.

35. Underneath of the bottom seat cushion the ribbon cable insulator is slid down the cable so that the connector at the other end of the ribbon cable can be disconnected.

36. The ribbon cable retaining clip on top of the seat bottom assembly is removed. Two screws are removed with a torx bit. The ribbon cable is carefully pulled through the hole in the seat frame to allow the seat frame to be removed without damaging the cable.

37. Now the seat retaining bracket is removed from the seat assembly. This bracket prevents the seat from moving backwards past the seat-locking pin.

38. The rear plastic end cap must be removed in order to remove the seat frame.

39. The seat frame may now be removed from the seat rail by sliding it off the back end.

40. These are the parts needed to rebuild the seat-locking mechanism. They include the bracket that goes under the seat frame, two bushings that go inside the seat rail, and a new locking pin. Some square tail bikes use nylon or rubber bushings instead of the ones shown in this picture.

41. As you can see, the old slotted bracket is worn and must be replaced.

42. There are six torx head bolts with 1/2 in. nuts that must be removed to change the bracket.

43. The new bracket is installed and the nuts and bolts are replaced.
