Engine Disassembly/Assembly: Notes

WARNING: This page is about a different car, the 2016 Mazda CX-3. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • When the transaxle is installed, do not suspend the engine. Otherwise, the SST installation area of the cylinder head may be damaged due to excess weight. Only suspend the engine after separating the engine and transaxle.
  • Applying excessive force (force of 100 N {10.2 kgf, 22.5 lbf} or more) to the electric variable valve timing motor/driver may cause a malfunction. When servicing, be careful not to apply excessive force to the electric variable valve timing motor/driver using other parts or tools.
  1. To enable to install the SST  , disconnect the clip shown in the figure and set the wiring harness aside.

    Bolt: 

    • part number 99794 1025 or an M10 x 1.25, length 25 mm {0.98 in}

      Tightening torque 

    • 38-52 N.m {3.9-5.3 kgf.m, 29-38 ft.lbf}
  3. Engage the hooks of the SST (49 L017 5A0)  to the SST (49 UN30 3050)  .
