Mike the short answer is no the flywheels are ground to the same dept and the endplay should not change when the flywheel is swapped out. BUT in the real world what ever we assume bites us in the butt When reinstalling a flywheel on any 2.1 engine you need to proceed with caution because you run the risk of the dreaded dropped endplay thrust washer. You know this has happened when you tighten up the flywheel and the engine locks up. To prevent damage to the shim seat in the engine block and thrust washer slowly tighten the bolts after installing the flywheel and move the crank back and forth to check for binding. When binding takes place the seal and shims must be removed and the thrust washer put back up in place Other endplay fun can include lack of endplay when reading the dial indicator .I have spent a few hours on this and can tell you that I use new shims as a simple way to eliminate repeated vague readings with a dial indicator that worn and bent shims can produce flywheels with worn shim surfaces can require surfacing. This surfacing increases the endplay so the long reply is yes they can be different so you need to check the endplay after installing the flywheel and the bolts are torqued Always check endplay at TDC or BDC they have a sweet spot that lets the crank move just a little more freely

Hello and happy weekend! Today's question: is end play specific to a flywheel? If I change flywheels, do I have to reset end play? Or, more appropriate to my situation - if a rebuilder sets end play and ships to me without a flywheel, do I have to recheck and reset? Cheers! Mike in the garage and making progress :) |
