This applies (exceptions for '41 - '48) to '40 - '48 (not 60HP). Please note there were changes in 1941 to the return routing and then again, '42 - '48. In '41, there was a dedicated boss near the front - left side of the oil pan. A steel return line was routed to that threaded boss. In '42 - '48, the threaded boss was integral of the dip stick tube fitting. If there was no filter, a plug was inserted in the dedicated boss. I believe but am not 100% certain that a steel line was used for the pressure line in '41 - '48. Perhaps someone with more knowledge of those years could chime in. The housing also was redesigned for '42 through '48. It appears very similar at first glace to the '40 - '41 filter housing. However, it is different. First Routing of the Return Hose The first routing from filter to block is as follows: 1) The hose attached to the angled fitting at the very bottom and center of the filter housing (Fig.5-57, H). The angle between the female and male threads of this fitting was a little less than 90 degrees so that the hose, which was threaded into the fitting, pointed slightly upward as it left the filter housing. Its initial path was parallel to the front axle underneath. 2) The hose passed through the hole in the rear of the filter housing bracket. A rubber grommet in this hole insulated the hose against abrasion. 3) The hose turned toward the fuel pump and was on top of the left spark plug wire conduit. 4) A cadmium plated clamp (Fig.5-57, D) held the hose to the left spark plug wire conduit. A round head bolt (26515-S2) and square nut (34129-S2) held the two pieces of the clamp around the hose. 5) The line terminated by threading into a special bolt/fitting (01A-18661), (Fig.5-57, C), that had replaced the left fuel pump mounting bolt. This first routing was the more common of the two since it was used from the beginning of 1940 production until the end of April, 1940. The second routing took effect at the beginning of May, 1940. Second Routing of the Return Hose The second routing from filter to block is as follows: 1) The hose attached to the angled fitting(Fig.5-57, H) at the very bottom and center of the filter housing. The angle between the female and male threads of this fitting was a little less than 90 degrees so that the hose, which was threaded into the fitting, pointed slightly upward as it left the filter housing. Its initial path was parallel to the front axle underneath. 2) The hose passed through the hole in the rear of the filter housing bracket. A rubber grommet in this hole insulated the hose against abrasion. 3) The hose turned toward the radiator and was on top of the left spark plug wire conduit. 4) The hose turned right and passed through a cadmium plated clamp (Fig.5-57, G), placed beneath the washers of the generator mounting stud, that secured the hose in place. A round head bolt (27081-S) and square nut (34141-S) held the two pieces of the clamp around the hose. The inlet to the housing was on the rear (towards the cowl) and near the bottom. This threaded hole received a 90º brass fitting (01A-18672) (Fig.5-57, I) for the inlet hose. Directly below that fitting was a decal that simply said “INLET”. At the center and very bottom of the housing was a threaded hole that received an 80° brass fitting (Fig.5-57, H). This hole and fitting were used, along with two different hoses and routings, to return filtered oil to the engine. Just to the front of this bottom fitting was yet another threaded hole. This drain hole was fitted with a brass hex head plug. The inlet (pressure) and outlet (return) hoses were made from an oil resistant compound and covered with a black lacquered braided cloth with a rough outside finish. The AC Spark Plug Company supplied these hoses to Ford. All fittings, with one exception, were brass swivel type. The exception was the late production return hose which had a “banjo” fitting on one end (Fig.5-57, F). Pressure Hose Routing While there were two different routings of the oil return hose, there was but one routing for the pressure hose. The pressure hose (01A-18669 ) threaded into a special angled brass reducing elbow fitting (Fig.5-57, A). This fitting was threaded into the horizontal hole at the back of the engine block near the oil pressure sending unit. From there the hose was routed forward near the bottom row of cylinder head studs and attached to the inlet fitting on the right side of the filter housing. A cadmium plated clamp (Fig.5-57, B), which was placed beneath the cylinder head stud between and just below cylinders number 7 and number 8, held this hose in place. A round head bolt (27081-S) and square nut (34141-S) held the two pieces of the clamp around the hose. There were two designs of this particular clamp. One design had a slot while the other had a hole. 5) The hose ended with a “banjo” fitting (Fig.5-57, F) at the base of the distributor. A special hollow bolt (Fig.5-57, E) replaced the lower right distributor housing bolt. With a copper gasket placed on each side of the “banjo” fitting, a leak free seal was attained Mike "Kube" Kubarth This message was edited by kubes40 on 3-27-22 @ 11:12 AM
