Yeah, it's called flat rate, and if you're good and experienced you can make alot of dough that way. I've been at Infiniti for almost 2 years, first year I got paid salary, second year I switched to flat rate. I average about 56-58 hours a week, while actually only working about 37. Last week I clocked 62.5 hours!! It works like this...every job pays a certain amount of book time, like an oil change pays .4/hour, you can normally get it done in .2/hour, and then you move onto the next job...say brakes, pays 1.5 hours, you should be able to do it in .6 hours and so on and so on. For the most part, you can make good time, but there's always those jobs that'll kill you, especially if it's your first time doing it...and especially warranty work, cause the factory pays the dealer for that and they're tight-asses!
NE-way, we will never replace the clutch alone at the dealer, a flywheel is always sold also, along with a pressure plate and a throw-out bearing. For the simple reason that when all the friction material on a clutch disc has worn off, the flywheel rubs against the disc backing plate which often gets very hot and heat-spots the flywheel which is bad. Every time a clutch is done at work the flywheel is always heat-spotted and dis-colored, I just did a clutch on an I30 on Friday...the lady only had 39K on the car and the clutch and flywheel are TOAST!! It all depends on how you drive...traffic is a different story though cause you really can't help but feather the clutch.
