Remove tappet assemblies from engine being sure that each one is kept with it’soriginal tappet block. NOTE: This procedure is the preferred method of installation. However, kit can be installed without removing lifters from engine. 2. Remove hydraulic piston retaining wire clip from one assembly at a time. Be careful not to bend wire clip during disassembly. 3. Completely disassemble tappet removing all parts. 4. Thoroughly clean all parts including tappet body. Remove any oil which might prevent hydraulic unit from fully collapsing during adjustment. 5. Insert one spacer from S&S HL 2 Tkit in tappet body. 6. Reassemble tappet in reverse order making sure original parts arereturned to their original positions. See Picture1. 7. Replace wire retaining clip in tappet body. 8. Put tappet back in original tappet block. 9. Repeat Steps 2 through 8 for three remaining tappets. 10. Reassemble engine with modified tappets. 11. Adjust pushrods. NOTE – In all cases engine must be cold and lifter must be at lowest point of travel for pushrod adjustment To prevent accidents, remove ground cable from battery. A. Remove spark plugs. B. Bring piston to TDC on compression stroke in cylinder to be adjusted. Normally both tappets will be at their lowest point of travel. C. Extend pushrod adjustment, collapsing lifter until piston assembly is in contact with HL 2 Tspacer and pushrod is tight. If tappets contain oil, as when pushrods are readjusted after engine has been run, or if all oil was not removed during installation, extend pushrod adjustment until valve is open (about five additional turns of adjusting screw). Allow 5 minutes for hydraulic unit to bleed down. If pushrod can be turned with fingers after bleeding down, lifter is not completely collapsed, and this step must be repeated. NOTE – perform this operation on one cylinder at a time. Do not turn engine until pushrod adjustment is complete. Turning engine while valve is held off the seat could result in valve to valve or valve to piston contact and serious valve train damage. D. Loosen pushrod adjustment until pushrod can be rotated with the fingers with slight drag. NOTE – Shortening adjuster an additional six flats or full turn from zero lash often results in quieter pushrod operation. This provides additional travel for the hydraulic piston assembly, which can improve the ability of the hydraulic unit to maintain zerolash under normal operating conditions. E. Tighten lock nut. F. Follow the same procedure for all four push rods. G. Recheck pushrod adjustment after a few hundred miles. NOTES ● It is a good idea to recheck pushrod adjustment in a new engine as valve train may tighten up due to gasket compression and valve seat wear. ● Upon initial start up after modification, HL 2 Tequipped lifters may be somewhat noisy for 10-20 miles. If lifters are still noisy after 20 miles it is recommended that pushrods be adjusted 1⁄2 turnlooser. See step D

1. Refer to the proper factory service manual for your model and year of engine, for removal of existing pushrods. 2. The Feuling pushrods are designed with a small adjustment parameter for rigidity creating maximum lift – These are not quick install pushrods and may require the removal of the lifter blocks and or loosing of the breathers/rocker arms supports. When loosening the rocker arm supports always remove the breather bolts first. 3. Clean and inspect each new Feuling pushrod including center oil hole 4. Feuling pushrods are marked Intake and Exhaust. The shorter pushrods are Intake and the longer pushrods Exhaust 5. Feuling recommends using new O-rings and gaskets where applicable to prevent oil leaks
6. Always pump up hydraulic lifters before installing them. Use an oil squirt can to fill the lifter with oil through the feed hole on the side of the lifter, push oil through the feed hole until the air bubbles are gone. If needed work the oil back and forth through the feed hole and pushrod seat with the squirt can. Light weight oil can be helpful. 7. Assemble and adjust one cylinder at a time, the servicing cylinder needs to be on TDC of compression stroke so the cam lobes are at their lowest point 8. Install pushrods into proper locations with the adjusting side of the pushrod down, towards the lifter. Slide the pushrods through the pushrod covers up into the rocker housing and set the pushrod on the seat of the lifter. We recommend filling the pushrods with oil then maneuver the pushrod up into the rocker arm seat. 9. Torque rocker arm housings and breathers to factory torque spec’s 10. See the instructions for your lifters for the proper adjustment. All Feuling hydraulic lifters run best at . 090″ – . 100″ of crush.
