Articulation Lock Pin
Illustration 6 g03725294Inspect the articulation lock pin bores for signs of damage. Holes should allow the locking pin to fit without excessive play. The bores should not be elongated and no deformation or damage to the plates should be present. Inspect the front frame lower side plate to bottom plate weld toes for any signs of cracking. The articulation locking pin should be present in the stored position.Front Frame
Illustration 7 g03725296Inspect the side plate to top plate welds at the rear of the front frame (both sides of frame). Inspect weld between the front frame top plate and circular plate welded to the bottom of the top plate.
Illustration 8 g03725303Inspect the front frame centershift. The vertical welds on both ends of the front and rear fish plates (both sides of the frame) should be inspected for cracks. Inspect all welds around the front and rear centershift plates, again on both sides of the frame. If cracks are found, inspect the adjacent parent material for any signs of cracking to include the frame top and bottom plates.
Illustration 9 g03725307Inspect vertical weld on the front frame side plate as well as the adjacent top and bottom plate welds in the vicinity of the vertical weld for any signs of cracking. Inspect the side plate to bottom plate weld where the frame curves down toward the bolster. Examine the transition area at the rear side of the bolster for signs of cracking. Both sides of the frame should be inspected.
Illustration 10 g03725311Inspect the front frame above the link bar. Damage to the frame in this area indicates possible link bar issues or damage to the front axle oscillation stops. Inspect the bolster pins for signs of movement, there should be no relative motion between the bolster pins and the front frame. The pin retainer bolts should be snug and U-shaped plates that retain the pins welded firmly in place. If the bolster pins are moving in the frame bores, retainer plates may need to be rewelded/repaired, pins replaced, and possibly the bolster pin bores in the front frame repaired/line bored. Front Axle
Illustration 11 g03725314Inspect the front axle weldment where the front gussets connect to the main axle body. Inspect the welds that wrap around the main axle body for signs of cracks. Inspect all motion joints on the front axle for presence of grease. Apply a force to the tie rod ends in an upward/downward motion, no play should be noticed in this joint. Ensure that tie rod boots are present and undamaged.
Illustration 12 g03725320Inspect inboard steering cylinder mounts and pins for any signs of damage. Pin retention bolts should be tight. Inspect the spherical bearings for any cracking in the bearing cages or other damage. If the spherical bearings are damaged, inspect the bores in the axle body where they are installed for any signs of yielding or damage.Drawbar
Illustration 13 g03725325Inspect draft ball welds on drawbar (all three). Inspect drawbar beam to divider plate welds on both sides of drawbar. Inspect welds on drawbar bottom plate
