RE-BUILDING OVERVIEW
If 5050 XX pedal becomes loose or feels gritty when it turns, then the pedal needs to be rebuilt. crankbrothers can rebuild your pedals for you, or you can rebuild them yourself using a rebuild kit available from your local retailer or crankbrothers (www.crankbrothers.com). It is relatively easy to replace the needle bearing and cartridge ball bearing. The typical tools required are 2mm, 6mm, and 8mm Hexes, and an 8mm socket and driver. You'll also need some grease and a rag. Applying the grease is easiest and most thorough if you use a grease gun, but it can be done manually, too. For more information, please contact your local retailer or crankbrothers.
DISASSEMBLY
step 1: Remove End Cap with an 8mm hex tool.
step 2: Remove and discard the Nut using an 8mm socket and a 6mm on the Spindle.
step 3: Remove Spindle out of the Body Assembly and place on a clean rag.
step 4: Remove and discard Cartridge Ball Bearing. If it does not fall out, then push out from other end using a 6mm hex or similar object.
step 5: Remove and discard the inner and outer seals.
step 6: Remove Needle Bearing, if necessary In many cases, the needle bearing will not need to be replaced during a rebuild. However, the needle bearing can be removed by a small flat bladed screw driver. If the needle bearing is too tight, the very best method is to push a flat strip of metal about 16mm x 1.5mm by 120mm down the slots in the body, as shown on the picture. The metal piece fits into the two slots in the body. This will push out the needle bearing. For example, a strip of "plumber's metal tape" is sometimes the correct dimension. You can also try pulling the needle bearing out by digging the head of a nail under the back of the needle bearing. Pull on the nail using a pliers or similar. Or, you can push a large flat bladed screw driver through the body and tap out the needle bearing.
step 7: Clean parts using a cloth rag or paper towel, wipe the grease out of the interior of the Body Assembly, the entire End Plug (if it is to be reused), and the outside of the Spindle.
To remove needle barring
REASSEMBLY
step 1: Bearing Push new cartridge Ball Bearing into Body Assembly.
step 2: Install new needle bearing into the Body, if the original was removed. Be sure it is pushed all the way in.
step 3: Install inner Seal 2 into Body so that the small rubber lip is facing outwards. Grease and install outer seal 1 on Spindle.
step 4: Apply grease to all surfaces of the Spindle that will be contained within the Body Assembly except threaded end.
step 5: Push Spindle into the Body Assembly, being careful that the Seal doesn't get pinched or the sealing lip inverted.
step 6: Install Nut using an 8mm socket and a 6mm Hex in the Spindle. Tighten firmly to 30in/lb (3.5NM). WARNING: The Nut must be tightened correctly or the Body Assembly could fall off during riding and cause injury.
step 7: Install End Plug with an 8mm hex. Be sure the Oring on the End Plug does not get pinched on the pedal Body.
