Flexible Engine Mounts - Positions
When you look at the engine mount positioning drawing you may think it is not laid out in a logical order.
Remember that Japanese writing is right to left, down the page, so it's half right for everyone. 
Check the Dimensions chart for the I.D. code for your engine.

Flexible Engine Mounts - Installation Tips
- Position as per the table.
- Install only in a fore and aft direction along the engine bed bearer.
- The elastomer must not be twisted after the top nut is torqued up.
- 1 full thread must protrude from the top of the nut after the top nut is torqued up. (If not a spacer should be placed under the mount).
- If possible, the engine mount bracket should sit as low as possible on the mount to increase the mount life.
