jump (or bump) starting

Have to put in my thoughts.

There should be no bump involved. Do not "pop" the clutch. Think of the way you go up through the gears when accelerating. Unless you always give your passengers whiplash and chirp the tires when you shift up. Gentle is the word and use the same gear you would use when accelerating at the speed you are at. Having knowledge of what is actually happening when the tranny is in or out of gear and what happens when you push the clutch in helps. Oh and how the engine is involved in all that.

I have used this technique a lot over the years due to being too poor to waste gas, having a dead battery and no funds to replace it or just having to drive a POS the wouldn't idle well.

As far as reverse tourque harming the drive train, if done correctly it is the same as taking your foot off the gas when decelerating. In other words the clutch is designed for reverses in forces. That's why many clutch plates have springs in them.

As to EOC, I never thought about the pilot bushing (is it really a bearing now in cars/light trucks?) but you should never keep the clutch depressed for long periods of time. Shift to neutral and let the clutch out. Less wear on the through out bearing.

I have known and ridden with people who pushed the clutch in every time they let up on the gas. Why? They were told to by someone. Believed the car would stall otherwise, even at speed. Never was successful at converting any of these people.

So do your EOC right, enjoy but know you didn't invent it. Been around since there were cars with clutches.

And be gentle restarting it using the proper gear and don't "pop" the clutch.
