No worries about any oil leaking out - it can't holes are all blind. The FORD TRACTOR OEM SWINGING DRAWBAR was first used on the 8N, but only the 8N-802 CLEVIS BRACKET was included with the new tractor; the Dearborn Swinging Drawbar was an optional accessory. There were four studs used on the first early 802-A brackets to the undercarriage diffy case and they are blind holes so there is no concern for losing any oil. The studs were 5/8-11 x 5/8-18 x 2.46 and used a 5/8-18 Hex Nut and lockwasher. In late 1950 the clevis was altered, 8N-802-B, and used 5/8-11 x 1-3/4” Hex Bolts. In 1951 the clevis was changed to a welded assembly and the hex bolts changed again to 5/8-11 x 1-3/8”. The revamped and improved swinging drawbar, p/n NCA-809, was first released with the 600 & 800 Models but could also be used on the NAA and 8N. The revised clevis used 7/16-14 bolts. The NAA/Jubilee would use the 5/8-11 x 1-3/4" Hex Bolts.
