Liberally apply assembly lube to every surface of the camshaft. Install the camshaft into the cylinder head (the lobes should be pointed down) and align the decompressor shaft dowels with the weight arms. Install one of the camshaft sprocket holder bolts and tighten to less than finger tight, you should be able to move the camshaft very slightly back and forth, roll the crank over until the other bolt hole is exposed and insert the sprocket bolt and tighten to less than finger tight. Install the cam chain tensioner assembly, do not install the spring, spring dowel, washer, and bolt. Using the spring from the cam chain tensioner very slowly push the tensioner shaft in until the cam chain slack has just been taken out, this is witnessed by the very slight lifting of the opposite end of the cam out of the cylinder head cam journal, do not over tighten the cam chain at this point, if you do, remove the tensioner assembly and retract the plunger again and start over. (If it stays too tight it will stretch the cam chain prematurely and cause cam sprocket damage when the engine is assembled) Roll the camshaft toward the back of the machine (clockwise) loading the sprocket bolts against the back of the sprocket bolt holes, while holding the camshaft in that direction, tighten the sprocket mounting bolt to 14 ft/lb of torque. Rotate the engine in the opposite direction that you rotated it earlier and align the TDC mark, tighten the other sprocket-mounting bolt to 14 ft/lb of torque. Verify the cam timing and crankshaft TDC marks are in alignment

For 2000 & later models removal of approximately 1/4 of an inch off of the shifter arm bushing is likely required. Doing so will allow installation of the retaining clip & washer onto the shifter arm. It is good practice to double check how much material should be removed before cutting the bushing. See fig. 1 & 2 Install supplied Main drive gear bearings & countershaft needle bearings using special tool # 97-164 NOTE: Lightly coat bearings with assembly lube or gear oil for easier installation. Install supplied Main drive gear retaining clip & verify that it is fully seated and cannot come out. Do not re-use old bearings or retaining clip. Install supplied Main drive gear into bearings using special tool # 97-166 See fig. 3 Install supplied trap door gasket & verify that it is on correctly. Install supplied 6 speed gear set making sure to align the countershaft with the needle bearing assembly. Slowly slide in gear set until the mainshaft & countershaft will not slide in any further. Lightly tapping on the trap door (while verifying that there is no interference) with a soft blow hammer will then fully seat the shafts & trap door. See fig. 4 Once gear set is installed use the supplied 5/16-18×1-1/2 & 1/4-20×1-1/2 bolts to secure the trap door. Torque the 5/16 bolts to 15 ft-lbs w/ red loctite (high strength) Torque the 1/4 bolts to 9 ft-lbs w/ red loctite (high strength) See fig. 5 FIG. 1 FIG. 2 FIG. 3 FIG. 4 FIG. 5 2 FIG. 6 At this time check to make sure all gears rotate freely & that all slider gears slide with no interference. Lightly lube & install supplied quad seal onto main drive gear. See fig. 6 Install Main seal using special tool # 97-164. See fig. 7 Install original spacer onto mainshaft. NOTE: Beveled side goes in towards quad seal. See fig. 8 Install supplied transmission drain plug & supplied speedo sensor plug with gasket. Install supplied shifter forks onto appropriate slider gears. See fig. 9 Lightly lube & install supplied shift fork shafts. NOTE: Short shaft is installed from the right side with the threaded hole facing out. Long shaft is installed from the left side & should not protrude from the right side of case. See fig. 10 Install supplied shift fork shaft allen head plugs. (Use red loctite to prevent movement of plug & to aid in sealing)

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

Upon installation of your WEB-CAM camshaft, check the following. These operations are very important to engine
life, please follow instructions! If your cam is described as a bolt-in in the WEB-CAM catalog, you may skip 1-5
below. Check piston to valve clearance. Provide the necessary clearance by removing material from the piston Minimum .050″ intake, .080″ exhaust.1. Check valve to valve clearance. It may be necessary to remove material from the valves or sink valve seat height in head. 2. Check the valve spring retainer to valve guide clearance at maximum lift. Remove material from the top,of valve guides to provide a minimum of .030″ clearance. 3. Check for valve spring coil bind at maximum valve lift. Clearance at every coil should be at least .015″4. Be certain that cam and/or rocker arms rotate
freely in head or block. Remove material from head,block, or rocker arms where necessary.5. Engine and cam life depend on proper installation. New or reground followers should be used when installing WEB-CAM profiles. Apply the provided
assembly lube to cam lobe and follower surfaces

Remove the plug bolt from the back of the cam chain tensioner assembly. It is under pressure from the spring. Remove the spring and pin. Remove the bolts and tensioner assembly from the cylinder. Release the lock on the tensioner assembly and push the tensioner rod into the assembly so that it is fully retracted. Remove the eight 5mm Allen headed bolts that hold the cam caps in place. Remove the cam caps; be aware of the locating dowels in the caps to keep them from falling into the engine. It may be necessary to pry very lightly on the caps to lift them off their dowel pins. Do not use the cam lobe as the pry point. 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. Using assembly lube, lube the shim buckets and bearing surfaces for the camshafts in the cylinder head. Set the exhaust camshaft 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. 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. Check the location of the cam lobes. The camshafts are marked, and preset to 108-degree centers. If the lobes are not where they should be, adjust the positioning of the camshaft by rotating the sprocket one tooth on the chain. Do this until it is in the correct position as before you removed the camshafts. Check the positioning of the crankshaft for the TDC mark
