The trick is to press the clutch pedal in as seldom as needed. So long as the clutch is engaged, the crankshaft and the input shaft are spinning as one, so the pilot bearing is just along for the ride. It only spins that bearing when there is a difference in shaft speeds, which only happens when the clutch is disengaged. So people that sit at a stop light for 30 seconds with their foot on the clutch, are going to wipe that bearing out MUCH faster than a guy who leaves the trans in nuetral and foot off the clutch until the light turns green.
I've learned that many people CAN drive a manual in as much as they can make the vehicle move and not stall the engine, but they do not always know how to operate one
properly that will allow for long component life. Many of my friends are always shocked I am able to tow so many heavy loads with small Japanese 4cyl pickups and VW Transporters without breaking anything.
