Dismantle
45 To dismantle a loading bar assembly continue as follows (Fig 6.3):
45.1 For each yoke type track roller-follower (125):
45.1.1 Press out spirol pin (127) from interference fit side of loading bar (one side is
clearance). Ensure side wall of loading bar (122/131) is not distorted during this operation.
45.1.2 Slide axle retainer (124) towards exposed roller face to release roller axle (126). Both
retainers (124) must be correctly positioned before axle (126) may be removed.
45.1.3 Push out roller axle (126) and remove roller (125) and two axle retainers (124).
45.2 Repeat 45.1 for second roller (125).
45.3 If necessary, drawn cup needle bearing (123) may be pressed out. Ensure adequate support to
prevent distortion of loading bar (122/131).
Assemble
46 To assemble a loading bar assembly proceed as follows (Fig 6.3):
46.1 Apply white bearing grease to all bearings and the faces of axle retainers (124).
46.2 If drawn cup needle bearing (123) requires fitting this must be pressed into the loading bar flush
with the base of the counterbored hole.
46.3 For each yoke type track roller-follower (125):
46.3.1 Hold roller (125) and two axle retainers (124) in position and pass roller axle (126)
through the hole in loading bar, retainers and roller.
46.3.2 Slide axle retainer (124) inward to retain roller axle (126) (retainers engage grooves
around axle) and ensure the smaller holes in axle retainers (124) align with the small holes in the
loading bar.
46.3.3 Secure axle retainers (124) with spirol pin (127) passed through the loading bar via the
clearance hole in the counterbored face.
46.4 Repeat 46.3 for second roller (125).
46.5 Apply white bearing grease to the ends of each roller axle (126) for protection.
NOTE: If the holes do not align it is possible axle retainers (124) are incorrectly seated in axle
(126) grooves.
