WHAT CONFIGURATION OF FASTENING HARDWARE WAS USED TO SECURE MY ENGINE SPLASH PANS TO THE FRAME?
In the process of re-restoring my December 1928 Tudor, (with a frame that has the 1/4” holes in the front cross member for the first generation engine splash pans) I’m finding that the hardware definition for these pans is quite confusing.
On p. 1-7, the Judging Guidelines stipulate a 1/4-28 hex head bolt and square nut. The Standard Hardware booklet and the Dec. 1, 1929 Parts Price List show no 1/4-28 nut, but Ford’s May, 1938 Hardware & Trimming Supplies Catalogue depicts the nut on p. 143, as 350917-S2, an engine pan to frame nut used from 1928-37.
On p. 11, the Standard Hardware booklet, a quantity of eight, “engine pan to frame bolts” is specified with a B-75 (1/4-28 X 9/16, 1/2 Square Head and cotter pin hole) configuration, that was deleted in December of 1929. Yet in that same section, provision is defined for eight, 1/4-20(3/16 X 1/2) square nuts…for what? Eight
A-23515 cotter pins are also specified, which leads me to the conclusion that a square head bolt, square nut and cotter pin below the nut were used until the solid front engine mount/related front frame cross member were modified, resulting in the reduced need for only six hex head engine splash pan to frame mounting bolts.
I recently examined an all original, August ‘29 coupe that had six, A-20534, hex head bolts (w/the cotter pin hole as show in the photo), lock washers, the square nut, but no cotter pin.
I couldn’t find any A-20553’s, so I had some made, and they’re shown in the photo w/o the cotter pin holes because I have to make a drill fixture to bore the 3/32” holes. It would also seem logical that after the front engine mount/front frame rail change, the A-20534 was used with lock washers and a 1/4-28 nut, in the interest of cost.
Is there any other Ford documentation on this matter?
