How to Install Variable Length Pushrods in a Harley-Davidson Evolution Engine

Pushrods are the longest and most visible pieces in a chain of mechanical components that connect a cam shaft inside a Harley-Davidson Evolution engine, with the rockers that open and close the exhaust and intake valves in a Harley cylinder head. The "lift" of these valves determines how much air and exhaust enters and leaves the cylinders. Within this chain of components, pushrods or rockers may be adjusted. It is easier to adjust pushrods than it is to pull apart the top of the engine. Harleys are shipped with non-adjustable pushrods, but the motor company does sell a set of quick install adjustable pushrods that bolt in as follows.

Instructions

    1

    Shift the motorcycle into top gear. Raise the bike on a motorcycle jack until the rear wheel is completely off the ground.

    2

    Cut the stock pushrods in half with a bolt cutter and pull them off the engine.

    3

    Remove both spark plugs with a spark plug socket and a socket wrench. Shine a flashlight into the front spark plug well and look into it.

    4

    Slowly turn the rear wheel by hand until the front piston is at the top of its stroke.

    5

    Replace the O-rings, the lower pushrod covers and the spring cover keeper with new components supplied in the kit by hand using a flathead screwdriver when needed.

    6

    Loosen the locknut on all of the pushrods with an open end wrench and adjust them to their shortest length.

    7

    Install the pushrods with pushrod covers by hand, ensuring that the adjuster end of the pushrod is down and the ball end of the adjuster is in the tappet socket. Adjust the pushrods for your motorcycle according to the instructions in the kit.

    8

    Lower and remove the motorcycle jack. Replace the sparkplugs with a sparkplug socket and socket wrench.

How to Install a Harley-Davidson Easy Effort Clutch Kit

Harley-Davidsons Reduced Effort Clutch Kit, sometimes called "Easy Effort," reduces the effort needed to squeeze the infamous Harley clutch lever by 30 percent, and it is one of two products intended to decrease clutch pull. The reduced effort clutch has been standard equipment on all Twin Cam Harleys since the beginning of the 1996 model year. The reduced effort clutch kit installs on all Twin Cam 88 and Twin Cam B 88 motorcycles sold before 1996.

Instructions

    1

    Raise the motorcycle on a motorcycle jack until the bike is upright and level, but not elevated.

    2

    Drain all primary fluid from the primary chain case drain plug on the bottom of the chain case. On recent models, the plug is a hex nut and should be loosened with a socket wrench.

    3

    Remove the top and rear inspection cover screws on the racetrack-shaped inspection cover in the middle of the primary cover. Remove these screws with an Allen socket. Remove all eleven primary cover screws around the perimeter of the primary chain case cover with an Allen socket.

    4

    Remove the primary chain case cover, the cover gasket and both tower gaskets. Discard all three gaskets.

    5

    Disassemble the clutch pack until you can remove the diaphragm spring. Replace the standard diaphragm spring with the diaphragm spring in the reduced effort clutch kit.

    6

    Replace the primary cover gasket with a new gasket. Replace both tower gaskets with new ones.

    15

    Replace the original inner and outer ramps with the replacement inner and outer ramps included in the kit. Screw, but do not tighten, the clutch cable fitting into the clutch release cover.

    16

    Place the new outer ramp in the side cover and place the three original ball bearings in the outer ramp slots. Re-seat the retaining ring with snap ring pliers.

    17

    Connect the end of the clutch cable to the ramp coupling. Install the coupling on the replacement inner ramp. Position the inner ramp and coupling in the clutch release cover.

    18

    Install a new clutch release cover gasket and replace the clutch release cover. Tighten all six screws to between 84 and 108 inch-pounds with an Allen socket and torque wrench.

    19

    Tighten the clutch cable fitting with an open-end wrench to approximately 40 inch-pounds of torque.

    20

    Replace and tighten the transmission drain plug with a socket wrench and hex socket. Replace and tighten the primary chain case drain plug using a socket wrench and hex socket.

    21

    Refill the transmission with the amount of transmission fluid specified for your motorcycle in your owners manual. Readjust the clutch cable adjusting nut with an open-end wrench until there is no more than 1/8-inch of free play in the clutch handle.

    22

    Lock the adjusting nut in place by tightening the lock nut with a second open-end wrench. Recover the clutch cable adjusting nut assembly with the rubber boot.

    23

    Remove the clutch cover in the primary chain case cover by loosening the five Allen bolts with an Allen socket and socket wrench. Remove the clutch cover gasket and discard.

    24

    Add primary chain case fluid until the fluid just touches the bottom of the clutch plates. Install a new clutch cover gasket, replace the clutch cover and tighten with an Allen socket and socket wrench.

    25

    Carefully lower and remove the motorcycle jack. Allow the motorcycle to lean left on the jiffy stand.

How to Change a Harley Davidson Softail Gas Tank

Saturday, October 19, 2013 | Labels: , , , , , , , , | 0 comments |

The popular Harley-Davidson Softail model has a durable gas tank, but exposure to extreme weather conditions can cause leaks or other malfunctions. If you notice your fuel level falling too fast while driving, you need to replace the gas tank. Rather than taking your Softail to the shop to have a new tank installed, you can do the job yourself right at home. You can purchase a new Softail tank at your local Harley dealer or an auto parts store.

Instructions

    1

    Disconnect your Softails battery by removing the cable from the battery terminal. Locate the fuel valve and switch it to the "Off" position.

    2

    Locate the carburetor and the fuel line that runs from it to the fuel tank. Disconnect the fuel line from the fuel tank, but leave it attached to the carburetor to prevent any contamination.

    3

    Remove all the bolts that secure the seat to your Softail. Make sure to remove the main seat bolt that is located under the front of the seat. After you have removed all of the seat-mounting bolts, pull the seat off the motorcycle to give you access to the gas tank.

    4

    Remove the bolts that secure the gas tank to the body of the bike. These bolts run all along the perimeter of the tank. Carefully lift the tank out to avoid spilling any fuel.

    5

    Install the new tank in place of the old one and secure it with bolts along its perimeter. Reattach the seat to the Softail and secure it with the mounting bolts.

    6

    Connect the fuel line to the new tank. Turn the fuel valve back to the "On" position and reconnect the battery cable.

How to Reduce the Oil Temperature on a Harley Davidson

Friday, October 4, 2013 | Labels: , , , , , , , , , | 0 comments |

Most Harley-Davidsons have air-cooled engines, and two factors contribute to their overheating. Harleys are delivered from the factory tuned so that the gas-air mixture that combusts in the cylinders has too much air and not enough gas. Such a condition is usually called either "running lean" or "running hot." To more easily meet environmental goals, Harley has taken several steps, from sealing carburetors to making fuel injections difficult to reprogram, that make it difficult to correct the improper factory tuning. The easiest way to reduce engine and oil temperature is to install an oil cooler.

Instructions

    1

    Loosen and dismount, but do not disconnect, the voltage regulator and the bottom of the frame down tubes, using a socket wrench. Allow the voltage regulator to hang down supported by the wiring harness.

    2

    Remove the oil filter with an oil filter wrench. Drain the oil into a pan.

    3

    Separate the halves of the oil filter adapter included in your oil cooler kit. Set the rear piece of the adapter in place on the oil filter mount and thread the one-inch lock nut onto the oil filter mounting stud.

    4

    Tighten the lock nut with a one-inch socket and socket wrench. Apply thread locker to the adapter screws included in the kit.

    5

    Secure the front half of the fitting adapter to the back half with the adapter screws. Turn the screws with an Allen wrench. Tighten the screws on both the front and back of the oil filter adapter.

    6

    Attach but do not tighten the two angled brackets included with the cooler kit to the voltage regulator mounting studs. Install the voltage regulator on the vertical holes of the angled brackets. Tighten the voltage regulator screws with a box wrench.

    7

    Attach the oil cooler ground wire to the right mounting stud. Tighten the nuts and hardware from your cooler kit to the mounting studs with a socket wrench.

    8

    Position the pre-assembled oil cooler above and resting on the voltage regulator. Insert the mounting screws and spacers included in your kit through the cooler unit and cross-member. Securely tighten the cooler unit mounting hardware with an Allen wrench.

    9

    Connect the oil lines that came with your kit to oil filter adapter. Tighten the hose clamps with a screwdriver. Install a new oil filter on the oil filter adapter.

    10

    Cut the oil cooler lines to length with scissors. Attach the open ends of the lines to the cooler fittings and secure with hose clamps. Tighten the hose clamps with a screwdriver.

    11

    Route the red power wire from the cooler up the frame to the headlight. Cut the wire to length with wire cutters. Strip the oil cooler power wire and splice it to the headlight power wire.

    12

    Cover the splice with heat shrink tubing. Shrink the tubing with a heat gun.

    13

    Slide the oil cooler cover in place. Tighten the top two and bottom two cover-mounting screws with a screwdriver.
