PIS oil pump bracket (If equipped) 3. Water bypass pipe 7. Idler pulley (NC) (If equipped) 4. NC compressor bracket (If equipped) 8. Left engine mount Step 2 1. Install the SST (engine hanger) using the holes shown in the figure. Gartner Banana

ENGINE STAND MOUNTING 2. Install the SST (arms) to the holes as shown in the fig- ure, and hand tighten the SST (bolts). 3. Assemble the SST (bolts and plate) in the specified position. 4. Assemble the SST (nuts, hooks, and bolts). 5. Install the SST to the respective arms. 6. Adjust the SST (bolts) so that less than 20mm (0.79 in) of thread is exposed. 7. Make the SST (plate and arms) parallel by adjusting the SST (bolts and nuts). 8. Tighten the SST (bolts and nuts) to affix the SST firmly. 9. Mount the engine on the SST (engine stand).
