I know it is confusing but I believe they are referring to the washers shown on page 242, Figure 29. The washers are on the end of the mainshaft/1st gear. They slide up to the larger, 4 gear. Because they are telling you to slide the assembly together the 1st gear is on one end and the 2 washers go on last (the end of the shaft on the end opposite the 1st gear). If you look at the photos on page 242 the 2 washers are shown in the correct order. Good luck.
