I point out this different part number for the drain screw washers used on some of these gearcases only because I had an issue while working on one….The standard 311598 washer would not fit very well into the lower fill hole, its OD was just a tad too big…And I could tell the washer was not going to seat properly….Finally looked up the actual part number and found that it was 307552 and had not been superceded to the standard 311598….
So, if the 311598 won’t fit into the cavity relatively easily, order the 307552 washers…
