How To Install A Shimano Derailleur

How To: Installing A Rear Derailleur (Install Similar a Pro!) [Video]

Words past: Max Morgan

Being out on the trail with your derailleur not shifting through the gears properly tin can be an aggravating matter. Subsequently reading this MTB How To, you should be an good on how to install and set up your rear derailleur. Here we are going to be installing a Shimano XT M8000 rear derailleur for a 1x11 drivetrain. Installing a derailleur from Sram or Box Components follows a very similar method.

What Tools Exercise We Need?

To get the task done right, we are going to need the right fix of tools. To install and set upward a new rear derailleur, we are going to need a set of allen keys, a phillips screw commuter, cablevision cutters, chain break tool or chain pliers, and a pair of pliers. To get a closer look at what's inside a pro tool box, cheque out our Pro Tool Box Check.

one. Remove Chain and Sometime Derailleur

• Before we get started with the new derailleur, remove the old one and get it out of the mode.
• Remove the chain as well. Even though this is a Shimano chain, it is using a 11 speed Sram Powerlock link for quick removal and install. Using the concatenation quick link pliers, remove the chain.
• This is a good time to supercede the shifter cable and housing. So remove that equally well.

2. Mountain New Derailleur

• Before installing the new derailleur, make sure the electric current derailleur hanger is in expert shape. Make sure that the hanger is visibly straight, has no stress marks or nicks, and that the threads are non damaged. If the derailleur hanger is damaged, the new derailleur volition never shift like it should.
• Double check that the new derailleur has some kind of thread locker on the threads. This will go along the threads from backing out and the derailleur coming loose from all the vibrations when riding.
• Using a 5mm allen central, mountain the Shimano XT derailleur. Make sure you don't over tighten.

iii. Install Concatenation

• If you are installing a brand new chain, see our MTB How To: Installing A New Chain to make sure you set the right chain length.
• When installing a Shimano chain, make sure the engraving on the concatenation links confront outward. Shimano bondage are directional.

4. Fix High Limit Screw

• At present we need to adjust the high and low limit screws. These are here to limit the derailleur's maximum movement in either direction so that the chain does non go thrown off the cassette.
• Start with the loftier limit screw. Yous will meet an H embossed next to the correct limit screw. The loftier limit spiral limits the derailleur when in its highest gear (smallest cog).
• Turn the limit screw clockwise with a 2mm allen key to move the derailleur towards the bigger cogs and vice versa. Line upwards the idler caster on the derailleur with the highest gear.
• At this point, there is no cablevision tension on the derailleur as the cable and housing has not been attached. While pedaling the bike in a bike stand, button the derailleur in toward to the larger gears to shift the derailleur manually. Brand certain that when released while continuously pedaling, the chain drops dorsum in to the highest gear with ease.

five. Set Low Limit Screw

• Repeat the same process described higher up to set the low limit spiral. Use a 2mm allen key to arrange the limit spiral.
• You volition have to pedal the bike in the stand up and push the derailleur manually into the everyman gear. Make sure that the derailleur allows the concatenation to observe its mode into commencement gear with ease.
• Turn the depression limit screw clockwise to move the derailleur towards the smaller cogs and vice versa. Line up the upper idler pulley on the derailleur with the lowest gear (biggest cog).
• Remember setting the limit screws does non impact how the derailleur indexes through the gears, but limits the derailleurs travel in either direction.

6. Install Cablevision Housing and Cable

• Now it's time to install the cable housing and shifter cablevision.
• Measure the right length cable housing and cut it to length using your cable cutters. Subsequently the cutting is made, make sure the ends of the housing are not crimped.
• Around the base of operations of the shift levers on the shifter, remove the plastic phillips caput screw with a screwdriver and button the new cable through the shifter. Reinstall the plastic phillips head screw.
• Feed the cablevision through the housing and attach the advisable ferrels to the ends of the cablevision housing.
• Run the cable through the derailleur, make sure the shifter is in its hardest gear, pull the shifter cable tight past mitt, and clench the cable downwardly using a 4mm allen key.
• Using the cable cutters, cut the cable giving yourself 1-2 inches of excess cable past the cablevision clamp. Crimp the end of the shifter cablevision to foreclose it from splitting.

7. Adjust Cablevision Tension

• Now it is time to make some terminal adjustments so the concatenation is indexing through each gear perfectly.
• Use the barrel adjuster at the shifter to adjust the cable tension. Turning the barrel adjust out increases the cable tension and makes it easier for the chain to index upwardly into an easier gear.
• Turning the butt adjuster in decreases the cablevision tension and makes it easier for the chain to index down into a harder gear.
• While pedaling the bike in a stand, offset in the highest gear (smallest cog) and shift the derailleur upwardly one gear at a time. If the chain hesitates to up shift into a bigger cog, increment the cablevision tension.
• Fine melody the cable tension and so the derailleur is shifter upwardly and down flawlessly.
