I've searched and can't figure this out.
I have an 87 wrangler with a weak engine. I've got a good used pullout drivetrain from a 95. (knew the owner, it was free and all that stuff.) I got most of the accessories And it would appear to faster and more desirable to use the 95 accessories. (It has a higher amp alternator. I like the PS setup better.) I'm narrowing down the parts I need to swap the engine. I was going to use the 87 intake and exhaust, other engine mounted sensors and such. I want to keep the 95 tranny because of the external slave.
Jeep lists two different numbers for the flywheels and two numbers for the Crank packages. I know if your Crank sensor is out of kilter your not running and I get to do all of this in a weekend. I figure I have to swap the flywheel. Is my assumption of swapping the flywheel accurate? Do either the 87 or 95 use a keyed crankshaft? As in the bolts are not equally spaced so you can only install the flywheel one way. If both are keyed are they keyed the same? If they are not keyed, is there a correct way to install the flywheel having the number 1 cylinder set to tdc? I imagine there is a correct way or the flywheel is keyed to get the Crank position sensormarks set correctly.
