Disassembly
Safety First: Disconnect the saw from the power source.
Remove Accessories: Take off the saw blade, fence, and switch assembly.
-
Access Bearing Housing:
Remove the tabletop, noting the position of any shims.
Loosen the motor mount and remove the V-belts one at a time.
Remove Blade Shroud: Raise or lift the motor as needed to access the geared bearing housing.
-
Remove Geared Bearing Housing:
Loosen the pinch bolt or cap screw securing the housing.
Raise the arbor to its maximum elevation so the geared bearing housing clears the front trunnion.
With an assistant if necessary, carefully pry or pull the geared bearing housing off the pivot shaft.
Clamp the housing securely in a bench vise if available.
Removing Bearings
-
Pulley and Locking Components:
Remove the pulley setscrews.
Remove the nut on the end of the arbor shaft.
On newer style arbor castings, remove the bearing lock collar and its three screws before taking off the nut.
-
Remove Arbor:
Using a brass punch or rubber deadblow hammer, carefully drive the arbor out of the housing.
Support the pulley and catch any shims or spacers between the pulley and the bearings.
The bearing next to the arbor flange often comes out with the arbor—if so, support the bearing and tap the arbor free using a soft hammer and wooden block.
-
Remove Remaining Bearing:
Support the bearing housing carefully.
Using a long punch or rubber deadblow hammer, drive the remaining bearing out of the housing.
Inspection
-
Check Arbor and Pulley:
Inspect the arbor shaft for wear, especially at bearing contact points.
If the pulley locking setscrews were loose, check both pulley and arbor shaft for wear or undersizing.
-
Check Bearing Housing:
Ensure the bearings fit snugly in the housing and have not spun or worn the bore.
Replace any worn or damaged parts before reassembly.
Installing New Bearings
-
Seat First Bearing:
Use a wooden block or socket to gently seat the new bearing into the housing.
-
Seat Second Bearing:
Use a drilled wooden block and a rubber deadblow hammer to seat the second bearing onto the arbor.
-
Reassemble Arbor Components:
Insert the arbor shaft into the housing while installing spacers, the key, and the pulley.
Tighten the pulley setscrews securely.
Reinstall the bearing cap and left-handed lock nut.
Reassembly
Reinstall Housing: Slide the bearing housing back onto the pivot shaft and secure it with the cap screw or pinch bolt.
Reinstall Components: Replace the blade shroud, belts, tabletop (with shims in the same position), and other accessories.
Final Checks: Spin the arbor by hand to ensure smooth movement.
Test Operation: Reconnect power and perform a brief test run to check for vibration or unusual noise.
Note:
Always refer to your specific saw’s manual for torque specifications, part details, and safety precautions.
