| ASSEMBLING BRACKET BUSHINGS AND BRACKET WASHERS The bearing assembly, which fits upon the studs of both the upper and lower brackets, is made up of an inner cupped washer, a hardened steel bushing and an outer cupped washer. In mounting the Oil Springs upon the bearings, be sure that the lugs on the inner cupped washer fit into the holes in the face of the bearing stud, also that the lugs on the inner end of the hardened steel bushing fit into the slots in the inner washer. Pack washer well with hard grease. Place the Oil Spring bearing into position over the bushing, being careful not to move the inner washer and push out of engagement. Pack the outer washer well with grease and fit same so that the lugs on the outer end of the steel bushing fit into the slots in the outer washer. Draw up the bearing stud nut tight and cotter pin. (The bushing is longer than the Oil Spring bearing so that the bearing nuts can be drawn up tight without jamming the bearing.) If the nuts are drawn up sufficiently tight there should be no side lash of the Oil Spring bearings on the studs. These should be held firmly in position. If a side lash is found, it is either due to the nuts not being drawn up tight or else to the lugs on the bushing not having been properly fitted into the slots in the bearing cupped washers.

REMARKS In fitting front upper brackets we remove sleeve on stem of lamp bracket and use but one nut and lock washer, cutting off projecting stem to clear top flange of Oil Spring. The upper front bearing pads are sent blank so you can drill when properly placed under frame so Oil Springs clear cross tube and give 7" - 7 1/2" between upper and lower bearing studs. The upper corner of Oil Spring case raises 3/16" on complete compression when upper stud is 2" in front lower stud. To allow greater distance between crank handle and absorber, bend shank thus | ||
