It was also said to be the first to use cranked axles, successfully at least.

The incident resulted in a redesign and replacement of the crank axle.

This increased maintenance (particularly with broken crank axles) and as a result the boiler pressure was brought back down.

While this improved stability, the "crank axles" were extremely prone to breakage.

They were built with improved crank axles.

However, they differed from their American counterparts in that they were given inside cylinders and a cranked axle.

A crank axle is a crankshaft which also serves the purpose of an axle.

Memorize the distance from the centre of the crank axle to the top of the saddle, measured in line with the seat post.

Not only were there frequent failures of the cranked axle shafts, with such large drivers, they would have set the boiler too high.

A new 2-2-2 design was soon produced with horizontal inside cylinders under the smokebox and additional bearings to support the crank axle.

It was built due to combat the frequent failure of crank axles on contemporary inside cylinder locomotive designs.

It had a fixed undercarriage, the main-wheels mounted on a cranked axle plus a tailskid.

I know that the crank axle is slightly offset such that, typically, my right knee starts to ache with many hours in the saddle.

Little is known about the class which is variously described as having a 'dummy crank' or a 'crank axle'.

An immediate problem was the frequency of broken crank axles on the inside-cylindered 2-2-2 locomotives from a range of manufacturers.

However, once designers began to overcome the problem of the breakage of the crank axles, inside cylinder versions were found to be more stable.

The modification was the inclusion of an additional (inside) cylinder between the frames, and a crank axle was fitted to the middle driving wheels.

It had a tendency to derail and had to be rebuilt with inside cylinders and a cranked axle.

Connecting rods linked the bell cranks to the crank axle (the axle on the left in the illustration).

The central axle was a complicated forging as a four-throw internal crank axle, although following traditional Stephenson practice.

Initially, outside cylindered engines were ordered because of the frequency of crank axle breakage with inside cylinders.

On 2 April 1909, a passenger train became divided and was derailed due to the failure of the crank axle on the locomotive hauling it.

The works made forgings for marine engines, shafts for use in paddle steamers and crank axles etc.

These inside cylinders' main rods were connected to a rear crank axle with a connecting rod between the two axles to power the front axle.

Most bottom bracket crank axles except the very cheapest are sealed units which can be screwed in and out of the bike frame with a special tool.
