How to Remove and Replace the Bottom Bracket on an Indoor Cycling Bike


Following is a basic guideline of removing and replacing the bottom bracket on an indoor cycling bike. Due to the different brands of indoor cycling bikes and designs for bottom brackets, the following should only be used as a guideline. If any of the information is not exact to the bike being serviced, refer to the service manual or call Sportsmith for further help.
Common Tools Needed:
Phillips Screw Driver
Set of Allen Wrenches (standard and metric)
Bottom Bracket Tool
Cotterless Crank Puller Tool
9/16" Socket
Ratchet Wrench
Pedal Wrench
Crescent Wrench
You will begin by removing the outside belt/chain guard by using either or both the Phillips screw driver and Allen wrenches. It may be necessary to remove the drive side pedal (using the pedal wrench) in order to completely remove the outside belt/chain guard.
Once the belt/chain guard is removed, you will need to remove the belt/chain. If the unit is belt driven, you can simply "walk" the belt off the pulley by pushing the belt to the outside while turning the crank backwards. **CAUTION: PINCH POINT ** If the unit is chain driven, most use a continuous chain that can be "walked" off the sprocket just like the belt. **CAUTION: PINCH POINT ** Some chains may use a connecting link and can be separated at the connecting link to remove the chain. The connecting link is different in appearance from all other chain links.
Now it is time to remove the crank arms. How to Use a Cotterless Crank Puller Tool
It works best to place the bike upside down for best leverage to remove the bottom bracket. (If placing the bike upside down, ensure proper seat adjustment for best bike balance.) Begin removing the bottom bracket from the drive side of the bike. This side has a reverse thread. You will need to turn right to loosen and remove the bottom bracket. Place the teeth of the bottom bracket tool into the teeth of the bottom bracket cup. Using the ratchet wrench or crescent wrench to turn the bottom bracket tool, you will turn right to loosen and remove the bottom bracket. (If removal of the bottom bracket is difficult, it helps to use a crescent wrench in combination with a bolt threaded into the bottom bracket shaft to hold the tool in place while applying pressure to break the bottom bracket loose.) Remove the bottom bracket from the frame. Remove the bottom bracket cup and/or lock ring from the non-drive side of the bike. This is a standard thread. You will turn left to loosen and remove this bottom bracket cup and/or lock ring.
Install the new bottom bracket from the drive side and tighten flush to the frame. Install the bottom bracket cup and/or lock ring to the non-drive side and tighten.
Re-install the crank arms and pedals. Make sure the crank arm bolts are tightened to the proper torque. If unsure of proper torque specs, refer to the equipment service manual or call Sportsmith.
Re-install the belt/chain onto the pulley/sprocket. If belt/chain was "walked" off the pulley for removal, it can be "walked" onto the pulley/sprocket by placing the belt or chain along the bottom of the pulley/sprocket. Carefully, turn the crank arm forward while lifting on the belt/chain. **CAUTION: PINCH POINT ** Continuing turning the crank forward until the belt/chain is in place.
Re-install the outside chain guard and test the unit. Ride the bike without tension and test with tension. Ensure functionality and feel of the ride. Make any adjustments if necessary

How to Identify the Type of Bottom Bracket on a Schwinn IC Pro


Video about Identifying the Bottom Bracket on a Schwinn IC Pro Bike

  • This video will help easily determine what kind of bottom bracket you need for your Schwinn IC Pro
  • You see in the video there are four available
    • The first one showed is the OEM style bottom bracket, on both ends it is a square tapered shaft bottom bracket
    • We offer a Sportsmith bottom bracket kit including the crank arms and crank bolts
      • This is also a square tapered shaft bottom bracket
    • We also offer two ISIS style bottom brackets
      • One is a 1 7/8" diameter
      • The other is 1 3/8" diameter
      • As you can see in the video these both have a round splined shaft
      • To identify which ISIS bottom bracket you need you will want to remove the crank arm and measure the hole in the frame that the bottom bracket mounts into
  • You will have to determine if you need a round splined shaft or a square tapered shaft
  • If you do need the round splined shaft you will have to know if you need the 1 3/8" or the 1 7/8" diameter bottom bracket
  • Knowing these things can reduce the frustration of buying the wrong parts and shorten down time greatly

Bottom Bracket & Spindle Replacement of LeMond RevMaster


Part 1 Video Discussing the Dis-assembly & Inspection of the Bottom Bracket & Spindle for a LeMond RevMaster Bike

  • This Part 1 video will demonstrate how to inspect and adjust or remove and replace the bottom bracket and spindle on your Lemond Revmaster
  • Tools needed for this procedure:
    • 8mm Allen Wrench or Socket
    • Cotterless Crank Puller Tool
    • Lock Ring Removal Tool
    • Bottom Bracket Tool
    • Phillips Screwdriver
    • 4mm Allen Wrench
    • Bungee (optional)
    • Rubber Mallet
    • 7/8" Wrench
  • To begin remove the belt cover, there are four screws
    • You will need a 4MM Allen wrench
  • Now remove the two screws on the back from the opposite side of the bike
    • You will need a Phillips screwdriver
  • Now position the crank arm as seen in the video and remove the belt cover from the bike
  • Before removing the drive belt, tighten the brake assembly so that the flywheel is locked in place and loosen the torque on both bolts using an 8mm Allen wrench or socket
    • Do not remove them at this time only loosen them by a half a turn or so
  • Using a 7/8" wrench loosen the belt idler
  • Now use a 4mm Allen wrench to loosen the tension adjustment bolt completely, but do not remove it from the frame
  • Now remove the drive belt
    • To aid in this process you can use a bungee to slide in behind the belt at the top, as shown in the video
  • Then pull away from the bike while spinning the crank arms
  • Now remove both crank bolts with a 8MM Allen wrench or socket
    • Removal of the crank bolt on the left side of the bike is the same as removal from the right side
  • Now remove the crank arms with a crank arm puller, threading the outer portion into the crank arm as shown in the video
    • Be sure to thread the outer portion in as far as possible to prevent damage to the crank arm threads or the tools threads
    • Use a 7/8" wrench to make sure the outer portion is threaded in completely
    • Now spin the handle clockwise to press the crank arm off of the bike
    • Be careful when the crank arm comes off as if you are not holding it, it can fall in the floor
    • Also use the wrench to loosen the tool before removing the crank arm from the unit
    • Now you can unthread the tool from the cranks arm by hand after removing the crank arm from the bike
  • Next inspect the bottom bracket cups for looseness, to do this use the bottom bracket tool by hand to see if you can turn either of the bearing cups
    • To further verify the adjustment of your bottom bracket use a rubber mallet to tap lightly on each side of the spindle to check for movement from side to side, if you have movement, or one or both of the bearing cups is loose, you need to re-adjust the bottom bracket. If you are only inspecting the bottom bracket and did not find any need for adjustment you would re-assemble the bike at this point
  • Once the crank arms are removed look closely at the spindle
    • It should have defined edges and be smooth
  • As you can see by the video our spindle needs to be replaced
  • Next you will need to remove the lock ring
    • The lock ring is around the bottom bracket cup on the left side of the bike
      • In the video is an example of a lock ring
    • To use the lock ring tool you slip it over the lock ring using the three notches and torque the lock ring in the proper direction
      • This one needs to be turned counter-clockwise to loosen
    • Then remove the lock ring by spinning it off the bearing cup
  • Next you will need to use the bottom bracket tool to remove the bottom bracket cups
    • Begin with the left side
      • Slip the tool into the splines of the cup and loosen
        • For stubborn bottom brackets use a 5/16"-24 x 2" bolt and some washers with a 1-1/4" wrench
          • Slip the tool into the splines and thread the bolt with the washers into the spindle
          • Get it snug but not completely tight
      • Now use the wrench to turn the cup counter-clockwise for the left side and remove it completely
    • Remove the cup from the right side now
      • Slip the bottom bracket tool into the splines of the cup and turn it clockwise to loosen
        • For stubborn bottom brackets use a 5/16"-24 x 2" bolt and some washers with a 1-1/4" wrench
          • Slip the tool into the splines and thread the bolt with the washers into the spindle
    • If you cannot get the cups loose with this method try turning the bike on its side to get better leverage as shown in the video
  • This concludes the dis-assembly and inspection procedure of the LeMond RevMaster bottom bracket & spindle
  • Click here to see Part 2, re-assembly and installation to complete the replacement procedure

Got a 1999 Diamondback Wildwood bike and was trying to take off the crankshaft and front sproket. Do I need a special tool for that? What's the trick?


Hi, yes you do need a special tool. It's called a Crank Arm Remover. The tool is basically a modified puller that threads first into the inside of the crank, (after the bottom bracket bolt is removed) where it is bolted to the bottom bracket. Then, a second bolt is then threaded inward against the tapered shaft of the bottom bracket. Slowly the crank will lift away from the tapered shaft of the bottom bracket. Hope this helps.

Cant get the pins out of the crank brackets on the bottom of the crank. got the bolts out but there are pins on each side of the bolts. most engines have two more bolts on the outside edge but this one...


The bottom bracket is the dohickey that connects your two crank-arms together, and secures them within the bottom of the bike frame. The bottom bracket has threads around the outside that secure it into the hole in the frame. Inside, bearings surround a rotating spindle -- this lets the pedals turn free from the frame. Each side of the spindle has a mechanism to connect your crank. This may be square tapered bolts, a toothed ring (splined bottom bracket), or even a threaded bolt. The bottom bracket type must match the crank type (a crank with a square hole must be mounted on a BB with the square receiver).
Bottom brackets also come in different widths, and with different spindle widths: the bracket width should match the frame, and the spindle width should put the cranks out away from the frame, and allow the front derailleur to transfer the chain onto the smallest ring without hitting the bike frame. The BB will usually have its size printed on the cartridge, but you have to take it out to read the numbers. For example, a 68x116 bottom bracket is 58 mm wide as it fits into the frame, and the spindles are 116 mm apart. If you wanted the pedals a bit closer together, you might buy a 68x112.5 BB.
Sealed Bottom Bracket: If your bottom bracket is a sealed cartridge unit (as most are nowadays), it can't be serviced or adjusted. If it grinds, wobbles, or catches, it must be replaced as a unit. Just remove the old cartridge and replace the entire thing.
Take the chain off the chainrings, and lay it on the frame next to the bottom bracket. With the bike clamped in a workstand, shove the base of the crank-arms side-to-side to detect motion in the bottom bracket. Now try to pull the cranks away from, then back towards the bike to detect wobble. Turn the crank and listen for noises within the bottom bracket. These tests will help you identify a damaged bottom bracket.
To replace the bottom bracket, you have to do some major stripping! You must remove both the left crank and the right crank arm plus chainrings. See the crank section for additional information.

Removing doors can be tricky... if you need to reinstall them.
First remove the plastic cover top door if it's an over under. Usually the screws are 5/16 there are 3 screws usually. Remove 2 screws loosen up the third. swing the bracket out of the way. Reinstall the screws you removed, this keeps interior screw plate in place and does not allow it to shift. Remove the 3rd screw , Remove the bracket reinstall the 3rd screw.
lift up and remove the door rememder washer locations.
Is there a washer on top of the middle bracket? Do not loose this or get it confussed with the bottom washer on the bottom bracket. Next there should be 2 screws on the middle braclet.
Remove one, loosen the other swing the bracket around. Install the removed screw. Remove the second screw. Remove the bracket, reinstall the screw. Lift bottom door up remove.
Now do the same to the bottom bracket. Or do not remove the bottom bracket if you don't have to. hope thisd helps.
