Special Service Tool (SST)

1.  : Mazda SST number 2.  : Global SST number
1: 49 UN30 3050 2: 303–050   Engine lifting bracket		1: 49 L017 5A0 2: –   Support hanger		—

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, remove the bolts and clip shown in the figure and set the wiring harness bracket aside.
