MSTEM Guide – Install Battery / Side Support Bars

INSTALL BATTERY / SIDE SUPPORT BARS

Gather Necessary Tools and Parts:

Components:

  • Left and Right Side Supports
  • Side Support Bolt Mounting Kit
  • Rubber Side Support Inserts (Typically these come already installed within the frame from factory)

Tools:

Wrenches

  • 10mm Wrench (M6 Nylock Nuts)

Allen Wrenches

  • 5mm Allen (M6 Cap Bolts for Side Support Bolt)

Other Tooling Items

  • 2lb Dead Blow Mallet (For moving left seat support bars.)
  • Drill with 1/4” / 6mm Drill Bit

Installing Seat

Step 1: Install the First Chassis Support Bar

  • Take one chassis support bar and lubricate it with WD-40 or a similar solution to help it slide into the frame tube against the rubber bushing inside. Keep the support bar as square as possible during installation to avoid difficulties pushing it in if one side is uneven.
    • NOTE: If needed, use a dead blow mallet to tap the bar fully into the frame until it bottoms out.

Step 2: Secure the Support Bar to the Frame

  • 2.1: Use a drill with a ¼” bit to drill a hole straight down through the frame hole opening in the front tube.
  • 2.2: Run the bolt up from the bottom and fasten it with an M6 nylock nut on top. Positioning the bolt head on the bottom is preferable, as it’s shallower and less likely to drag on the track compared to having the nut on the bottom.
    • NOTE: Tighten the bolt and nut all the way. With the battery having significant weight, you don’t want to leave the side support loose to reduce it bouncing up and down on track and bending the support or frame as least as possible.

Step 3: Install the Second Support Bar

  • Repeat Steps 1 and 2 for the other side of the kart to install and secure the second chassis support bar.
