PURPOSE: To remarkably save the time and labour for manufacuring of a farm tractor, by enabling bearings, bevel gears, ring pins and a king pin to be all inserted into a farm tractor final casing whose top end is blinded, through the lower end of the casing.
CONSTITUTION: Bevel gears 14, 18 are assembled onto a king pin 9 in such a method that comprises the steps of fitting a final upper casing lower bearing 16 onto the intermediate section of the king pin 9 from the top end of the latter; then fitting the bevel gear 14 onto the top end of the king pin; fitting a final upper casing upper bearing 12 onto the king pin, the bevel gear 14 and the upper bearing 12 being checked to the king pin with the use of a ring 15; fitting an oil seal 35 onto the king pin 9 from the bottom end of the latter; fitting a final lower casing upper bearing 19 onto the king pin, the bearing 19 being checked to the king pin 9 with the use of a snap ring 23; fitting a lower bearing 20 onto the lower end of the projected section 17 of the king pin 9; and securing the bevel gear 18 onto the same. A final upper casing 4 is capped onto the topsection of the thus assembled king pin 9 from above.
