This procedure will insure uniform loading of the unit injector hold down clamp and the clamp bolts.
1. Put the clamp in position on the unit injector and install the two bolts and conical washers that fasten the clamp to the cylinder head. Hand tighten the bolts evenly.2. Use a wrench to the evenly tighten the bolts just enough to seat the unit injector. Be sure to check to assure the top surface of the clamp is parallel to the top surface of the cylinder head.3. Tighten the bolt adjacent to the rocker arm support to a torque of 47 N m (35 lb ft) while maintaining adequate clearance for the injector gauge on the opposite side.4. Tighten the bolt on the opposite side to a torque of 47 N m (35 lb ft).5. Use a scale to check the dimension from the top of the clamp to the top of the cylinder head adjacent to the each bolt. This dimension must be 110.0 1.0 mm (4.33 .04 in).
