- If you encounter resistance, ensure you are pulling directly outward to avoid damaging the housing.
Step 5: Clean the Area
Before installing the new bearings, clean the area thoroughly:
- Use a cleaning solvent and cloth to wipe down any dirt or debris.
- Inspect the housing for any signs of damage.
Step 6: Install New Bearings
Now, it’s time to install the new bearings:
- Apply a small amount of grease or lubricant to the new bearings.
- Align the bearings with their respective housing and press them in place.
- Ensure they fit snugly and are correctly seated.
Step 7: Reassemble the Miter Saw
Once you have replaced the bearings, it’s time to put everything back together:
- Replace the housing and secure it with the screws and bolts.
- Reattach the blade and blade guard.
- Double-check that everything is properly secured.
Step 8: Test the Saw
Before putting your miter saw back into regular use, perform a test:
- Plug in the saw and turn it on.
- Listen for any unusual sounds and inspect for smooth blade movement.
- If everything sounds good, it’s ready for action!
Tips for Maintaining Your Miter Saw Bearings
