Firm finger-tightening is sufficient.Tighten wingnut (4) so EN49982-1 retainer closes over and firmly grasps timing chain. Note:Do NOT tighten the wingnut with a tool of any kind. This fore/aftmovement will allow easier removal and installation of the chain later.Install EN49982-1 retainer intake side chain holder onto front cover by screwing in the thumbscrew-(2) on theEN49982-1 retainer finger-tight. The EN49982-1 retainer should be able to slide slightly via the slot the screw goes through. Loosen wingnut-(4) to open the clamping area of EN49982-1 retainer. Note:Do NOT remove or loosen any other camshaft bearing caps at this time, even if youintend to eventually remove the camshaft.Remove the camshaft front cap-(1). Mark the position of the chain to the camshaft position actuator – exhaust. Note:Be certain to clearly mark the position of the chain to the camshaft position actuator(s).Though the engine does not need to be set to a specific timing mark before startingthe procedure, the relationship of the chain to the actuator(s) is critical and mustbe reestablished on assembly.Mark the position of the chain to the camshaft position actuator – intake. If servicingboth camshaft position actuators and/or camshafts, loosen both bolts. The position actuators must stayfirmly attached until the retaining tools are in place, but they should be brokenloose while the chain is still tight and in position.Loosen intake and/or exhaust camshaft position actuator retaining bolts, dependingon which camshaft position actuator and/or camshaft you will be servicing. Note:Do NOT remove or back out the camshaft position actuator bolt(s) significantly, simplybreak them loose from their fully-torqued position. This puts the camshafts on “base circle”and will reduce their tendency to rotate from valve spring pressure when the camshaftposition actuators/drive chains are removed.
