00:00:12the source of that power is the next

00:00:14step in our motorcycle build the heart

00:00:17of the v-rod the engine all the

00:00:21components the transmission the water

00:00:23pump the Pistons are put together in the

00:00:25engine assembly area a 23,000 square

00:00:28foot factory within a factory over here

00:00:32we actually build the engine

00:00:39that’s the power before

00:00:41feel the life these employees may wear

00:00:45jeans and Harley t-shirts but there’s

00:00:46nothing casual about this line it

00:00:49requires focus and attention to detail

00:00:52the slightest flaw can cause it not to

00:00:56run properly

00:01:03you

00:01:06center stage is the engine assembly line

00:01:09divided into 10 workstations

00:01:11it’s a tough taskmaster the line

00:01:16advances every seven and a half minutes

00:01:18employees must work efficiently to

00:01:20complete their tasks oh you got a hurry

00:01:24right along which

00:01:29here’s how a motorcycle engine works

00:01:32inside the engine cylinders a spark

00:01:35ignites a mixture of air and fuel this

00:01:37causes an explosion which drives the

00:01:40piston down turning the crankshaft and

00:01:42that rotational force is transmitted

00:01:45through a set of gears in the

00:01:46transmission to the bikes rear wheel the

00:01:51v-rod’s

00:01:51engine build begins with parts about 370

00:01:54of them they’re hand checked for

00:01:56scratches breaks and imperfections in

00:01:58just two hours technicians will assemble

00:02:01this jumble into a working engine the

00:02:04clock starts ticking when they lift the

00:02:05v rods lower engine case on to the sub

00:02:08assembly line first step install the

00:02:12transmission and 5-speed gearing system

00:02:16the v-rod motor puts out an awful lot of

00:02:20horsepower

00:02:21to get that horsepower from the motor to

00:02:24the wheels you need a good solid

00:02:26transmission next the lower case and

00:02:31transmission join the main assembly line

00:02:33from computer-controlled torque guns

00:02:36that screw the individual parts together

00:02:37to heavy lifting manipulators that make

00:02:40moving the heavy parts easy this line

00:02:42comes packed with high-tech help even

00:02:51the silicon dispenser is automated with

00:02:53laser precision it traces the edges of

00:02:56the engine case the result of a perfect

00:02:58seal each part of the v-rod’s engine is

00:03:07designed for performance these are the

00:03:10Pistons to increase combustion and power

00:03:12they’re housed in big bore cylinders the

00:03:15water pump plays a vital part in keeping

00:03:17the high revving engine running cool the

00:03:20engine assembly is nearly complete and

00:03:22to finish it all off chrome clutch and

00:03:24alternator covers the end result the

00:03:28heart of the v-rod the revolution engine
