- 2002 Ford Explorer XLT
Well, my wife's 2002 Explorer (4x4) 4.0 experienced timing issues (stopped running suddenly, in traffic). I pulled the engine to replace the cassettes/tensioners. The front had already been replaced, the rear looks okay. When I turned the crank via the flywheel, only the crank turns. The keyway sheared off at the crank to jackshaft gear. Now I know the cams and chains are still timed together, along with the jackshaft gear, (and even the crank gear. Can I get away by lining up the crank to the gear keyway, pull the jackshaft bolt to ease the crank gear forward (after locking down the cams) and replace the halfmoon key? I am replacing the tensioners in the heads too. Should I do a compression check afterwards to see if the valves were bent? Or is this a non-interference motor?
