Harley Davidson(NYSE: HOG), a Wisconsin-based motorcycle manufacturers, is developing a new
pushrod engine.
The wear of brake pad lining and brake drum during operation leads to increase in the stroke of the
pushrod, whose 'out of adjustment' creates severe brake performance degradation.
The servos attach to the control systems via
pushrods and each servo (pitch and roll) weighs 3.4 pounds.
The number 3 cylinder exhaust
pushrod broke, due to a valve stuck in the closed position.
"When a lobe is up, the exhaust
pushrod actuates the exhaust valve, and when the mechanism is flat, the
pushrod misses its mark.
The 1,690cc 4-valve
pushrod V-twin engine can push the bike to a top speed of 125mph.

It's also the first convertible since the 1990s Azure that's fitted with Bentley's old school 6.7-litre twinturbo
pushrod V8 engine.
The TR6's inline 2.5-liter
pushrod (OHV, or overhead valve) engine was basically a carry-over from the TR250, as were most of its mechanical bits.
It is also a four-wheel drive with racing chassis, and
pushrod suspension.
It is powered by a 12-cylinder engine with a displacement of 6.5l and is equipped with a fast-shifting ISR transmission with five modes, permanent all-wheel drive and a racing chassis with
pushrod suspension and horizontal spring/damper units.
