[. . . ] Install the chain, use the take-up bolt to adjust the chain tension to allow about 3" sag in the center (remove links if necessary). 1 FIGURE 1 Front Idler Assembly Track Spacer Connect the Shaft From the Front Idler Assembly to the Extension Shaft by Coupling Two 48B12 Sprockets Together With #40 Chain and Masterlink. Extension Shaft INSTALL THE OPERATOR 1. Remove the 50B12 output sprocket from the operator and install the new 50B35 sprocket on the operator. The 50B12 sprocket will be installed on the extension shaft. INSTALL EXTENSION SHAFT 1. Determine the length of the extension shaft to be used and cut it to this length. Install the 48B14 sprocket provided on the end of the shaft by drilling a 1/4" hole through the sprocket and shaft and pinning with the 1/4" by 1-1/2" roll pin provided. Be sure that the shaft does not extend past the end of the sprocket and that the teeth of the sprocket are at the end of the shaft (Figure 2). Couple the shaft to the front idler assembly by butting the two 14 tooth sprockets together and coupling them with the #40 chain and master link (Figure 1). One of the bearings should be at the operator end of the shaft as close to the 50B12 sprocket as possible to prevent shaft flex. Be sure to properly pad out the bearings so that the shaft is parallel to the header. [. . . ] Bearing assembly should be mounted as close to the (50B12) sprocket as possible to prevent shaft flex.
