BMX Gloves View all. Battle of Hastings View all. Your cart. Your bag is currently empty. Step 1. Apply a small amount of grease to the inside of the bottom bracket on the frame.
Call us - With a rubber mallet, tap the first bearing into the frame. A piece of wood can be used as a barrier between the mallet and bearing to help prevent any accidental damage.
Insert the tube spacer into the BB, then install the second bearing the same way as the first. Install the spindle to the BB, so the same amount shows on both sides of the spindle. You may need a rubber mallet to knock it through. Loosely install the sprocket bolt to hold the sprocket on the crank arm. Then, insert the small dust cap onto the spindle followed by the sprocket and crank arm.
Pull the crank arm onto the spindle with the crank tool until no spindle is exposed between the bottom bracket and crank arm. Put the larger dust cap on the other side of the spindle then rest the crank arm on the spindle so you can see how far the spindle will sit in the arm. Both procedures described below are covered in our video on the same topic if you would prefer to watch that.
Loosen the wheel nuts using a 19 mm socket. Loosen the left side first. The wheel pulls to the left due to the chain tension which now immediately slackens. Then loosen the right side, allowing the wheel to move all the way forward in the horizontal dropouts. You are now able to lift the chain clear of the chainring.
An adjustable wrench is the right tool for this job. The locknut and bearing ring hold the crankset and bearing assembly together. The wrench adjusts to fit both the locknut and the bearing ring. Loosen then remove the lock ring and the washer separating it from the bearing ring. Use a standard or flat screwdriver plus a hammer to loosen the bearing ring. Position the screwdriver tip in the slot. A few light taps loosens the ring enough to remove it by hand.
As you screw the bearing ring along the crank and spindle, the whole assemblage loosens. Slide the bearing ring and the old bearing off the crank. Then slide the crank along with the remaining bearing through the bottom bracket shell. Mind the chainring during the process.
The second method uses First Components H press-fit adapter. You install the BSA compatible adapter into the bottom bracket shell, then install a cartridge bottom bracket in the adapter. Check out the post on Bottom Bracket Conversion Kits.
You screw bearing rings onto the spindle thread, one on each side. Each bearing cage rests against each bearing; the bearings rest against the bearing cups functioning as a bearing race. Tightening the bearing rings holds the assemblage together and holds the bearings firmly against the race. Adequately greased and maintained, these bearings will give years of reliable service. Then screw the bearing ring onto the spindle.
Give the bearing cups a wipe to clear any old grease and dirt away. These bearing cups are in very good condition so, although the bearing kit comes with new cups, there is no need to remove the old and install the new. Having cleaned the cups, apply a new coat of grease. Apply plenty of grease to the bearing. Push the grease into the gap between the bearing cage and each bearing. Grease the bearing ring you attached to the spindle earlier.
You should also grease the left, non-drive side bearing ring along with the spindle thread on that side. Install the spindle with the bearing ring into the drive side. Install the left bearing ring onto the spindle. Then begin to tighten it against the bearing. Getting the balance between tightness and looseness here is important.
If the ring is too tight, the bearing along with the spindle will not rotate freely. If the ring is too loose there will be movement. A loose crank will place more stress on the bearings, causing premature wear. It will, minimally, be noisy to ride. You can possibly get it right just using your hand. Then, insert the small dust cap onto the spindle followed by the sprocket and crank arm. Pull the crank arm onto the spindle with the crank tool until no spindle is exposed between the bottom bracket and crank arm.
Put the larger dust cap on the other side of the spindle then rest the crank arm on the spindle so you can see how far the spindle will sit in the arm. If the spindle is near the end of the arm, you will need to add some spacers.
Place the crank arm on the spindle and check it's inline. Once inline, use the crank tool to pull the remaining arm on until the spindle is no longer exposed. Install the spindle bolts and tighten until nothing is loose, but the cranks can still spin freely. Please complete all fields below to submit your Price Match.
