Steps to Replace Job Site Saw Arbor Belt or Motor

Service Procedure SP-JSS-190516-001

Tools & Supplies Required for This Procedure:

  • 2 Phillips Head Screwdriver
  • 5mm Allen Wrench
  • 13mm Wrench
  • Blade Wrench
  • SawStop Part #JSS-238

Procedure Steps:

(Before starting, please read instructions all the way through to ensure complete understanding)
To ensure safety, disconnect all electrical power to the saw.

  • Tilt the saw to 45 degrees.
  • Lower the blade completely and remove the fence from the saw and set aside.
  • Use a 5mm Allen wrench and a 13mm wrench to loosen and remove the four bolts that attach the saw to the cart and set aside.
  • Lift saw off of the cart and place upside down on a soft sturdy surface.
  • There are 15 Phillips head screws around the outer edge of the bottom that attach it to the saw body. Starting with the screw to the left of the counter spring indentation at the back and working counter clockwise, remove all 15 and the bottom and set aside. NOTE: When the last screw is removed, the bottom will spring upward a bit.
  • Remove the motor housing bolt that is directly above the motor power cord and set aside.
  • Remove the four bolts that fasten the motor to the elevation carriage assembly.
  • Turn the motor so it is oriented as shown below. On the left side of the arbor wrench you will notice a small hole near the end. Finger-tighten the arbor wrench to the motor plate as shown below with the M5x50mm bolt that was provided with your belt.
  • Re-install one bolt from step 7 through the motor plate into the bottom left motor mounting hole as shown below. (This will create a pivot point for the motor).
  • Put the new belt on both the motor and the arbor pulleys.
  • Pull on the wrench to apply tension to the belt and to align the motor mounting bolt holes.
  • Reinstall the remaining three motor mounting bolts using a 5mm Allen wrench.
  • Remove the bolt and wrench.
  • Reinstall the motor housing bolt using a Phillips head screwdriver
  • Tilt the saw back to 90 degrees. Above the motor is the counter balance spring that must be in the up position leaning against the trunnion.
  • There is a small groove on the bottom of the indentation that the top of the counter balance spring must seat in. You’ll want to “hover” the base over the saw and slowly lower it until the two match up.
  • Reinstall the 15 screws starting with the one that is left of the indentation. NOTE: When using a power screw driver, the torque must be set about midrange or you WILL strip them.
  • Place the saw back on the cart and reinstall the four 5mm bolts and nuts.
