Cleaning and Relubrication Perhaps the largest contributor to shortened chain life is inadequate lubrica- tion. All working parts of a chain should be lubricated uniformly. The use of the highest viscosity oil that allows for flow between the link plates and coats pin-bushing areas will normally provide the greatest wear resistance. Apply oil to the upper edges of link plates. This allows for the greatest access of oil to pin-bushing joints. For open drives, excess lubrication on outer chain surfaces should be removed, since it will either be thrown off during operation or serve to collect foreign materials. If foreign objects or surplus lubrication accumulates on chain surfaces to the extent of making re-lubrication of the joints impossible, the chain must be cleaned. Standard roller chains may be cleaned by washing in kerosene or any other good petroleum-based solvent. WARNING: These solvents are flammable. Agitate the chain to assure penetration of the solvent and a thorough flushing of the pin-bushing areas. Drain off excess solvent and inspect bushings and pins for wear. Replace the chain if wear is excessive or parts are fractured or missing. O-ring chains may be cleaned externallyby washing in kerosene. Do not use any other cleaning agent or the O-rings may be damaged. When cleaning O- ring chain, clean only the external areas of the chain. Do not attempt to force kerosene into the pin-bush cavity. Do not try to repair a worn-out chain by replacing individual links. The pitch of the new links will be shorter and will most likely result in chain fatigue failure and/or severe sprocket damage. For chains which are still usable, soak them in SAE 40 or 50 automotive engine oil (without additives). Flexing the chain in oil will assure greater penetration of lubricant. Inspect and clean sprockets. If sprockets are worn or damaged, they should be replaced.Installing new chain on worn out sprockets will significantly shorten the chain’s service life. WARNING: always wear eye protection when assembling or disassembling chain

Remove the 4 bolts that hold the exhaust cam cap in place, lift the cam cap off. It may be necessary to pry very lightly on the cap to lift it off its dowel pins. Do not use the cam lobes as the pry point. Be careful not to drop the dowels and also be careful to not lose the half moon shaped retainer for the bearing under the cam cap. Remove the 6 bolts that hold the intake camshaft cap and lift the cam cap off the camshaft, again, be careful to not drop the retainer or dowels. Lift the intake camshaft out of its pocket in the cylinder head casting. Remove the cam chain from the sprocket, set the stock camshaft aside. Lift the exhaust cam out of its pocket in the cylinder head casting and remove the chain from the sprocket. Do not drop the cam chain, dangle it over the side of the engine while keeping slight upward pressure on the chain to maintain its position on the drive sprocket on the crankshaft. Fit the half moon shaped retainers in the grooves of the Hot Cams camshaft bearings to ensure good fit, set retainers aside for the time. Using assembly lube, lube the shim buckets, bearing surfaces for the camshafts in the cylinder head, and pack some in the camshaft bearings. Set the exhaust cam into the cylinder head casting while at the same time fitting the cam chain over the sprocket. Make sure that you keep all the cam chain slack to the back of the engine. The cam chain pulls the camshaft sprockets in a counter clockwise direction and the slack of the chain must be kept on the cam chain tensioner side of the engine. The exhaust cam has two timing marks on it. When correctly installed one mark will be at the 9 o’clock position and the other mark will be at the 12 o’clock position. When correctly timed the mark at 9 o’clock will be aligned with the valve cover gasket surface. Repeat the above process for the intake camshaft. Again, make sure you keep the chain slack to the cam chain tensioner side of the engine. Check to be sure the crankshaft is still at TDC. The intake cam has two timing marks also. One at 12 o’clock and the other at 3 o’clock. When both cams are installed correctly, the valve cover gasket surface will form a straight line through the exhaust timing mark at 9 o’clock and the intake timing mark at 3 o’clock

1) Assemble & install the chain tensioner assembly over the primary chain as shown in figure 1. 2) Install the compensator sprocket with extender & spacer (numbers 5, 6, & 7, FIG 2)(#7 is not included in this kit), primary chain, chain tensioner, and clutch basket simultaneously onto the motor drive shaft & transmission main shaft. Rotate the chain drive slightly as needed to allow the splines to line-up. 3) Install the chain tensioner nut loosely on the chain tensioner bolt. 4) Install the sliding cam onto the compensator sprocket, & slide the compensating sprocket cover-assembly (#3) over the cam. 5) Apply 2 drops of Rivera “Red” thread-lock on the threads of the motor drive shaft, & install the motor nut loosely with the fingers at this time. The hex spacer (#7) and spacer (#2) as seen in fig.2 are not provided in Rivera Engineering’s chain drive kit. These components are required with some applications, and can be purchased from your local Harley-Davidson dealer. FIG 2 6) Apply 2 drops of Rivera “red” thread-lock on the threads of the transmission main-shaft and loosely install the clutch hub nut (left hand threads). 7) Place the HD “Primary Drive Locking Tool” HD-41214 on the primary chain as shown in figure XXX and tighten the motor sprocket nut to 150-165 foot-pounds. 8)Turn the locking tool 180 degrees and move it to the clutch sprocket. Tighten the clutch hub nut to 70-80 foot pounds (left- hand thread). Adjust chain tension so that the top strand has 5/8″- to-7/8″ of up and down play (cold drive train). Tighten the center bolt nut to 21-29 foot pounds of torque.

GL1800 TIMING CHAIN COVER INSPECTION NUT 1. Place bike on center stand. 2. Remove the inspection nut on the bike using a 17mm socket. 3. Remove the rubber o-ring seal from the inspection nut and place on new inspection nut. 4. Install the new inspection nut using the 17mm socket.

Disconnect battery. 2. Mark location of timing plate in relation to inside of cam cover. This will give a starting point for timing on new module. Remove old ignition if applicable (see manual) Clymer, Haynes. 3. If your bike is not equipped with timing rotor M/W# 53-528 OEM#32402-83 you must buy one (included in kit). Also a single fire coil is needed (included in kit) M/W# 53-632. Any single fire coil rated 2-4 ohms can be used. NO SOLID CORE PLUG WIRES (copper, silver) they will damage the unit. 4. Install module: helpful hints, early model nose cones, i.e. Shovel Heads, the hole for the wire may need to be drilled out. Align with previously scripted mark for timing. Use lockwashers for stand offs for correct clearance of cover plate. Run wire loom. 5. Connect wires, see wiring diagram. Tape unused wires, green or brown. 12v to tach (brown) will damage module. Set timing. 1996 and later should not be timed 20˚ BTDC as the OEM module, but at 35˚ BTDC. Use this mark when using timing light. If VOESswitch is not used you must ground VOES wire (green) while timing. Refer to manual for correct identification of timing marks. At start up and timing, set spark advance in middle position. FUNCTION SWITCHES LED timing indicator light: When out, shows TDC. When ignition is on, LED will light up. When engine is cranking LED will blink. Electric Start/Kickstart: Set accordingly. VOES/Race mode: VOES switch lets the motor run smoother and improves gas mileage. If you don’t use it or add one tape up green wire and switch to race. VOES switch to use, M/W# 53-652. Spark advance: High compression motors should use race mode and 93 octane or better gas. Changing from VOES to race changes advance curves. Agood rule of thumb is if the engine knocks when throttle is applied in high gear, turn back spark advance curve until it stops engine knock. RPMlimiter: Set at desired RPM to cut engine power. Rear Cylinder: This is for racing and should be set at a dyno. +/-5˚. Rear cylinder timing is achieved through this adjuster. Most should dial to middle setting and leave alone. After all switches are set, install cover with supplied gasket and feel the increased performance of a solid state single fire ignition. Again, we remind you, if you don’t feel confident about installing this unit, let a qualified mechanic do it and be assured you are getting the best performance and gas mileage possible.
