This Special Tool is required when changing Camshafts on the 4B11

To change the camshafts on the EVO 10's 4B11 engine there is a special tool that is required from Mitsubishi OEM tools, to unlock the timing chain tensioner. The Mitsubishi genuine parts part number is (MB992103). However the Mitsubishi tool design makes it too difficult for a singe person to work on the engine alone to complete the task. So the TOMEI TCT design utilizes the screw hole on the top of the head deck surface to lock in the TCT tool into position to allow the single staff worker to have hands free of that task to continue working on the head to complete the camshaft exchange job.

 


How To Release the Valve Timing Chain

Insert the precision driver (or similar tool of the same size) into the special service hole where the Timing chain tensioner is and hold it in there to keep it unlocked. The TCT release bar is then to be inserted into the timing chain gallery between the cam gears and pushed against the timing cam gear ASSY on the intake side which will push the chain tensioner inside the case and make it loose. Whilst the screw driver is in the service hole the TCT will relieve the tension on the chain when the TCT is pressured up against the tension..
