MOUNTED EQUIPMENT
Pre-installation
1. Put the ball end of diagonal strut (1) in the socket of bracket (4). Install and fix strut cap (2)
with four cap bolts (6).
2. Thread the strut in or out so that its eye is aligned with the push arm bracket hole and pin (9)
can be installed. Secure the pin. Repeat the same procedure to adjust the other strut.
3. Adjust the strut length so that:
Push arms (7) are pushed out in their blade brackets (8); the gaps should appear on the inner
face of the push arms and the track frames are positioned symmetrically between both push
arms (7). Then lengthen both struts by turning them out by ¼ to ½ turn to increase their
compression.
4. Tighten cap bolts (6) keeping an even gap between bracket socket (4) and cap (2). Determine
the number of shims (5) necessary to fill the gap. Add one more shim to ensure adequate end
play. Install the number of shims (5) determined earlier. Tighten cap bolts (6) to 450 [Nm].
Periodic adjustment: repeat steps 3 and 4.
5.15.2. TRUNNION, COVER, MOUNTING BOLTS.
Check the torque of the trunnion mounting bolts, push arm bearing cap bolts after the initial 10
hours of operation, and then periodically.
