Torque Values and/or Fastener Tightening Strategies
- All fasteners and threaded holes on the LH6 engines utilize metric threads.
- Certain fasteners should not be used again. Bolts, studs, or other fasteners that must be replaced, will be called out in the specific service procedure.
- Some applications may use a second design camshaft retainer plate and bolts. Refer to «Camshaft Installation»(ref-268156-S38516304842007101800000) .
- The camshaft sprocket is now retained to the front of the camshaft using a single bolt design with a torque and angle tightening strategy.
