•• Whenever removing injectors for compression pressure inspection, replace the gaskets with new ones
and tighten them with the specified torque.
1. Warm up engine until the normal operating temperature.
2. Remove the injectors. (Refer to FL Gr.)
3. Check the cylinder compression pressure.
(1) Insert a compression gauge SST(09351-27000, 09351-2A000) into the injector hole.
(2) Fully open the throttle.
(3) While cranking the engine, measure the compression pressure.
Always use a fully charged battery to obtain engine speed of 250rpm or more.
(4) Repeat step 1) though 3) for each cylinder.
