How To Replace Swing Arm Bearings on a Dirt Bike
How-To: Inspect and Replace Swingarm Bearings
What tools do I need to remove and install new swingarm bearings?
To remove and install new swingarm bearings, you will need a few tools. First, you will need a socket or wrench to remove the bolts that hold the swingarm in place. Next, you will need a drift punch or a similar tool to remove the old bearings from the swingarm. Finally, you will need a hammer to install the new bearings into the swingarm.
How do I properly measure the swingarm bearings to ensure a correct fit?
To measure the swingarm bearings, you will need a caliper. Place the caliper over the inner race of the bearing and make sure that the jaws are touching the side of the bearing. Then, take a measurement of the inside diameter of the bearing. Next, measure the outside diameter of the bearing. Finally, subtract the inside diameter measurement from the outside diameter measurement to get the width of the bearing.
Why do swingarm bearings need to be changed?
The swingarm bearings are what allows the swingarm to pivot on the motorcycle frame. Over time, these bearings can become worn and may need to be changed. If the bearings are not changed, they can eventually seize up, which can cause the swingarm to break.
How often should swingarm bearings be changed?
Swing arm bearings should be changed every 20,000 miles.
What are the signs that my swingarm bearings need to be changed?
There are a few signs that may indicate your swingarm bearings need to be changed. If you start to notice a creaking noise coming from the rear of your bike when riding, this is likely due to the bearings in the swingarm being worn and in need of replacement. Another sign is if you start to feel a “clunking” sensation when shifting gears or going over bumps in the road. This again is likely due to the bearings being worn and not providing as smooth of a ride as they once did. Finally, if you visually inspect your swingarm and notice any excessive play in it, meaning it moves more than it should, then this is a definite sign that the bearings need to be changed.
What type of bearings should I use for my swingarm?
There are a few things to consider when deciding what type of bearings to use for your swingarm. The first is the weight of the swingarm. Heavier swingarms will require stronger bearings that can support the additional weight. The second is the size of the bearings. Bearings that are too small will not be able to support the weight of the swingarm, while bearings that are too large will add unnecessary weight to the swingarm. The third is the type of material the bearings are made from. Different materials have different strengths and weaknesses, so it is important to choose the right material for the application.
The most common type of bearing used for swingarms is a ball bearing. Ball bearings are strong and can support a lot of weight. They are also relatively small, which makes them ideal for use in swingarms. The downside of ball bearings is that they are not very durable and can be damaged easily if they are not properly lubricated.
Another type of bearing that can be used for swingarms is a needle bearing. Needle bearings are much smaller than ball bearings, but they are also much stronger. They can support a lot of weight, but they are also more likely to be damaged if they are not properly lubricated.
whichever type of bearing you choose, it is important to make sure that it is the correct size and that it is properly lubricated.
How do I lubricate the new swingarm bearings?
To lubricate the new swingarm bearings, you will need to first remove the old bearings. Next, clean out the swingarm bearing housing with a degreaser and a brush. Once the housing is clean, apply a generous amount of grease to the new bearings and insert them into the housing. Finally, wipe away any excess grease and reinstall the swingarm.
What is the torque specification for the swingarm bearing bolts?
The swingarm bearing bolts on a motorcycle are typically tightened to between 20 and 30 ft-lbs of torque.
What are the consequences of not changing worn swingarm bearings?
If you do not change worn swingarm bearings, the consequences can be significant. First, continued use of worn bearings will damage the races and eventually cause the bearing to seize. This can lead to the swingarm being damaged and/or breaking, which can be extremely dangerous. Additionally, not changing bearings can lead to increased friction, which can lead to increased wear on other parts of the suspension, such as the shock absorbers.
Can I change my own swingarm bearings or should I take it to a shop?
No, you should not change your own swingarm bearings. You should take it to a shop because they have the tools and expertise to do the job properly.
