CHEVY - CHEVROLET  ROCKER ARM SHAFT & BUSHING SET - Part Number FS-954
For 1932-33 All; 1934 Standard models only., INSTALLATION INSTRUCTIONS: From 1932 on Chevrolet did not offer separate bushings for rocker arms. The reason for this was that the bushings for 1932 were so thin that they must be installed in the rocker arm BEFORE the oil groove was cut into the bushing. Our reproduction bushings come with no grooves. As part of the installation of these bushings, a groove must be cut into the center of the bushing for oil flow to the weep hole at the top of the rocker arm. Failure to do this will cause a lack of oil at the valve stem. After removing the original bushings, press in the new bushings into the rocker arms. Once the bushings are installed, drill a hole through the bushing, using the weep hole at the top as a guide. Drill the hole the same size as the weep hole. The next step is to cut a shallow groove in the bushing, all around the center of the bushing. One method to do this is using a Dremel tool with a flat grinding disk. Cut most of the way through the bushing but try not to go all the way through. It needs to have at least the width of the oil weep hole, but slightly wider won't hurt. Once the groove is cut all around the center of the bushing, use emery cloth to remove any rough edges. Fit the rocker arms to the shafts. Before installing, be sure to oil all bushing surfaces. Your rocker shafts may have shouldered bolts holding the rocker shafts to the rocker stands. There are four of these bolts. The shafts we provide will not allow for a shouldered bolt, so these must be changed. These are not a hardened bolt, so you should be able to go to an auto parts or hardware store and purchase bolts with no shoulder. CAUTION: When installing the rocker arm shafts, you must insure that the oil holes are on the bottom. Failure to do this will cause poor oiling to the bushings and therefore, premature failure of the bushings.
