how many hours take to put a fly wheel in 1993 jeep cherokee

Hello, Why are you looking to replace just the flywheel? For the closest approximation for labor, look up an estimate for a clutch replacement, it's basically the same labor. A factory flywheel for your jeep is up to $675, but having it resurfaced would be a viable, much cheaper option! https://repairpal.com/estimator/jeep/cherokee
