"When you heat up the wheel before you put it on the crankshaft that will enlarge the pilot bearing opening and the bearing will push in or fall in, they give you green loctite ADHESIVE (not the same as thread lock or sealant) to keep that in. If you hammer it in you chew the aluminum and force it in, heat it and it falls in same as installing it on the crankshaft cause a wobble pilot bearing that comes loose in an aluminum wheel will ruin that pilot bore and you'll have to use a bushing you don't want it to heat up when you are shifting the car and the pilot come loose that is why you must use that green loctite adhesive. If you do not heat the wheel then when you put the pilot in the wheel all you do is smear off all the adhesive and the wheel would expand when its hot while driving and pull away from the side and the bond could be broken. You MUST heat this wheel up, stick it in an oven on 350 for 20 minutes (you'll need welding gloves to handle it) and you'll see how loose it gets on the crankshaft and you'll know what is happening when you drive the car and the friction heats it up. You have the plate from an automatic to go under the bolt heads right?"
