1. Remove stock pushrods using a bolt cutter. 2. Place the motorcycle on a hydraulic center stand with the rear wheel raised off the ground. Remove spark plugs. CAUTION 1 WARNING 1 WARNING CAUTION 1 WARNING CAUTION ® i02097.tif Figure 1. Adjustable Push Rod Kit Number 17997-99A Pushrod Tube Adjusting Screw Flats Adjusting Screw Locknut 1 of 2 Exhaust Pushrod Tube has Thicker “Finished” area and is slightly longer Intake Pushrod Tube has Thinner “Finished” area and is slightly shorter 3. With transmission in gear use rear wheel to turn engine over until both front cylinder tappets are at their lowest point. 4. Replace O-rings, lower pushrod cover and spring cover keeper with new components supplied in kit. 5. See Figure 1. Loosen locknut on all of the pushrods and adjust them to their shortest length. NOTE See Figure 1. In Step 6, pushrods with the Thinner “Finished” area on the tubes must be installed to the Intake location on the cylinders; pushrods with the Thicker “Finished” area on the tubes are slightly longer and must be installed to the Exhaust locations on the cylinders. 6. Install pushrods with pushrod covers. Be sure adjuster end of pushrod is down and ball end of adjuster is in tappet socket. 7. If hydraulic tappets are used, adjust pushrods following procedure A. With solid tappets, follow procedure B. NOTE Pushrod adjustment must be made with engine cold. PROCEDUREA (Hydraulic Tappets) 1A. Adjust pushrod length to zero clearance. 2A. See Figure 1. With the pushrod tube kept from rotating with a 1/2 inch or adjustable wrench, slowly turn the adjusting screw with a 5/16 in. wrench, 2-1/2 complete turns counter clockwise (lengthening the pushrod) as viewed from the bottom. (You may wish to mark adjuster to aid in counting turns.) 3A. Hold adjusting screw and tighten locknut with 1/2 in. open end wrench against the pushrod tube. If pushrod turns with locknut use three open end wrenches, one to hold the pushrod tube, one to hold adjusting screw and one to turn locknut.

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

Installation with Stock Pushrods Refer to the service manual for your motorcycle model. Installation with Adjustable Pushrods Lifter-Cover Removal Installing or removing the pushrods with the valve train loaded can result in engine damage. On the cylinder being serviced, always set the lifters to the base circle on the cam before servicing pushrods, lifters, rocker arms, and valves. 1. Set the lifters of the rear cylinder to their lowest point, or base circle, on the cam. Refer to Setting the Lifters to the Base Circle in this instruction sheet. 2. See Figure 1. Insert a screwdriver into the slot on the side of the spring-cap retainer on the pushrod cover. 3. Press the spring-cap and retainer down while pulling outward to remove the spring-cap retainer. 4. See Figure 2. Lift the lower pushrod cover to reveal the lower third of the pushrod. 5. If the engine has stock pushrods installed and you are installing adjustable pushrods with this lifter-cover installation, go to step 6. If the engine already has adjustable pushrods installed and you are installing adjustable pushrods with this lifter-cover installation, go to step 7 6. Use a bolt cutter or similar tool to cut the stock pushrod. Avoid cutting the pushrods with a saw, grinder, or other method that may allow metal debris into the engine. Go to step 8. 7. Loosen the jam nut on each adjustable pushrod and resize each rod to its shortest length. 8. Remove the pushrod covers and pushrods from the engine. 9. Remove the O-rings from the seats in the engine at the top and bottom of the pushrod cover. 10. Remove the four screws fastening the lifter cover to the engine to remove the cover and gasket. 11. Remove old lifter-cover gasket material from the engine, taking care not to allow material to fall into the engine. Continue to Lifter-Cover Installation in this I-Sheet. Lifter-Cover Installation 1. See Figure 3. Verify that the lifter anti-rotation pin is in position. Installing or removing the pushrods with the valve train loaded can result in engine damage.

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.
