am3uuw00005082
(5)   Set the bracket securing the lower radiator hose aside to prevent it from interfering with the front shaft of the SST. (right side)
(6)  Set the cooler pipe aside to prevent it from interfering with the front shaft of the SST. (right side)
(7)  As shown in the figure, set the rear shafts of the SST to the left and right shock absorber bolts.
am3zzw00005427
(8)  Install front foot No.2 to the left/right front shaft of the SST, then align the groove of the front shaft of the SST with the folded up part of the vehicle as shown in the figure.
am3zzw00005428
(9)  Adjust the positions of the SST side bars so that they are the same height (left and right) and horizontal. Make sure each joint is securely tightened.
am3zzw00005429
(10)  Apply tension to the chain to secure the engine.

9.  Remove in the order indicated in the table.
