Changing Front Wheel Hub Assemblies

Friday, June 28th, 2013

OK, cruising around the internet, I found this question that someone asked…

What do I need on hand to change my front wheel hub assemblies?
I’m ordering Timken front wheel assemblies for a 2001 GMC sierra 1500 w/ 5.3L for both front wheels. Do I need anything other than this to change the hubs? (I mean, do I need any other parts? I have all the necessary tools.)

Here was the answer provided, by someone named Denis:

“If it’s 4WD, you may need an axle nut socket and a hub puller. I replaced the whole hub assembly on a friend’s 4WD Durango. There was a retaining clip that needed to be replaced. Other than that, it should be an un-bolt, bolt-in job.”

How are Ball Bearings Made?

Friday, June 21st, 2013

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.

The main purpose of a ball bearing is to lessen rotational friction and help radial and axial loads. This is possible by using at least two races to contain the balls and then send the loads via the balls.

With all the advancements in technology today, bearings can sometimes be put aside. However, there is no denying that myriads of machine parts won’t rotate without ball bearings. Household appliances, industrial machines, and car engines won’t run without them.

Here is a video of how they’re manufactured.

 

Applications for Light-Duty Vehicle Seals

Friday, June 14th, 2013

Seals are important in the automotive industry on so many levels. Oil seals, usually referred to as grease, fluid or dirt seals, are crucial in pretty much every running vehicle. Their main purpose is to protect all types of bearings through a variety of functions. Such functions include closing spaces in between moving and stationary parts of mechanical equipment, thus aiding in the prevention of lubricant escape as well as preventing contaminants from entering machinery. They also assist in stopping inter-mixture of two different mediums, like lubricating oil and water.

Some examples of places you might find light duty vehicle seals include :

  • Axles – a central shaft for a rotating wheel or gear
  • Camshafts – a shaft to which a cam is fastened or of which a cam forms an integral part
  • Crankshafts – sometimes called crank, is the part of an engine that translates reciprocating linear piston motion into rotation
  • Differentials – a device, usually, but not necessarily, employing gears, which is connected to the outside world by three shafts, chains, or similar, through which it transmits torque and rotation
  • Input shafts – the rotating shaft that receives power from the power source and introduces it into a mechanical system

When shopping for light-duty seals, look for those that have the following properties:

  • Machined rubber sealing edge – This paves way for accuracy and consistency, and a better sealing surface.
  • A flanged design – This will make it possible for easier and proper installation. Also, it will help in avoiding cocking.
  • A latex bore coat – It is known to seal the outer diameter leak path. It also helps in making up for little bore imperfections.
  • An extra dust lip – It assists in keeping damaging contaminants, like dirt, out of the bearing. It also helps prevent rust and corrosion from taking place.

Timken Bearings for Harley-Davidson

Friday, June 7th, 2013

There has always been a little bit of controversy as to whether Timken bearings are any good in Harley-Davidson engines. Truth be told, Timken bearings serve an outstanding purpose as long as they are operating in the power delivery arena that they are designed to operate in.

A certain amount of flex is acceptable, but when you have a motor that makes a lot of power, and when you get that prolonged load on there, it can unload inside the bearing. When it comes down to that, it’s possible for a roller to flick out and things get dramatic, but that does not happen with a Timken.

Timken bearings are captured, so you can’t get them out. It has a little bit of forgiveness because it’s pressed directly on to the crank. Everything is a lot more solid with Timken. The Timken has two bearings that are impeccably attached to one another, and it creates a lot sounder platform so the rollers do not come out. You only have to worry when you get into a big horsepower situation. That is when some issues potentially arise.
