Tips on Bosch VP 44 for Diesel Trucks

Owning a vehicle is a big commitment. And if you own a big diesel truck it may even be more of a commitment than you expect, especially if your truck is equipped with a Dodge cummins engine. The Bosch VP44 injection pump used in the Dodge Cummins engine from 1998 to the 2002 models has been to known to have its share of issues.

Bosch VP44 injection pumps perform four basic functions:

1 - Producing the high fuel pressure required for injection

2 - Metering the exact amount of fuel for each injection cycle

3 - Distributing the high-pressure, metered fuel to each cylinder at the precise time

4 - Varying the timing relative to engine speed.

The Bosch VP44 is an electronic rotary distributor pump that can vary fuelling and injection timing, and also contains fuelling, timing, and diagnostic data.

The following are the top two most common mechanical failures:

1 - Rotor Seizure Another mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most common cause for the seizure is a lack of lubrication. Since the Bosch VP44 injection pumps are lubricated by the fuel, weak lifts pumps can again be blamed for this failure. The seizure will then break the Drive Plate and the truck will stop running, never to start again, until the Bosch VP44 injection pump is replaced.

2 - Check Engine Code 216 This is the most common mechanical failure and occurs over a period of time when weak lift pumps, with low fuel pressure, rupture the diaphragm in the front of the injection pump. The timing piston will then vibrate to a point where it wears the housing of the pump down until the fuel is able to bypass the piston. Dodge has recognized this problem for some time, and they no longer even sell the lift pump that goes on the side of the block anymore, instead they replace it with a unit that is now mounted in the tank.

Overall the number one cause of Bosch VP44 injection pump failure is a drop in fuel line pressure which is usually due to a malfunctioning lift pump. Normal fuel pressure is around 15psi and if the pressure drops below 5psi an injection pump failure is probable. Remember bad lift pumps can run unnoticed until costly damage is done to the Bosch VP44 injection pump.

Preventing Bosch VP44 injection pump Failure The best way to avoid failures of the Bosch VP44 injection pump is to prevent them from happening. Purchasing a replacement lift pump, one that is of a better quality than what comes from the factory will help. If that option is too costly, you can also install a gauge to monitor your fuel pressure. With the gauge you will be able to know when your lift pump is going out and can easily fix the problem before you lose the Bosch VP44 injection pump.

Preventing problems before they occur is the best way to take care of your truck.

Important Support Tips on Sofa Legs
Important Support Tips on Sofa Legs

Although the frame construction is probably the most important factor in sofa construction, the sofa legs are also an intricate part as to whether the sofa will stay stable over its years of use. No one wants their beautiful sofa to become wobbly after a few months or a couple of years of use.

Wood Legs
If at all possible, you want to choose a sofa whose back legs are one piece with the frame. This provides the ultimate stability in wooden legged sofas. The front legs then should be double-dowelled, glued and screwed onto the frame. If the legs are only screwed on, they will not be stable within a short period of time because the screws work out. Some manufacturers staple the sofa legs on. This, too, is not a stable choice because the staples will easily work loose when the sofa is moved around.

Metal Legs
If you have a more contemporary designed sofa, you may have metal legs to choose from. These also need to be attached firmly to prevent wobbliness. Joints and legs can be welded, riveted, bolted, or screwed on. Welded legs tend to be stronger. Rivets and screws can work out over time, so they will be found mostly in less expensive sofas. Bolts can be a good choice for the sofa legs, especially if self-locking nuts are used because these will not allow the bolt to work out. http://www.alphafurnishings.com/

How to Fix Metal Table Legs
How to Fix Metal Table Legs

A broken metal table legs can ruin a good piece of furniture, but it does not have to. With a little epoxy putty, silver paint and the right know-how, you can quickly and easily repair a broken table leg. Then you can continue to enjoy your good-as-new furniture.

1 Remove the broken metal table legs from the table. Then, use a ?-inch metal file to smooth out any rough edges on the broken leg.

2 Knead the one-part epoxy putty in your hands until it begins to feel warm to the touch. Make sure to completely mix the putty until it is one consistent color.

3 Set the broken pieces of the table leg next to one another. Then use the epoxy putty to attach the two pieces back together, thus fixing the leg and making it one piece again. Smooth the putty, and allow it to harden for about three hours before sanding the table leg.

4 Use the sandpaper to sand the epoxy putty repair to a smooth finish.

5 Use the silver enamel paint and paint brush to paint over the repaired area, blending in the epoxy patch with the original parts of the leg. Allow two hours for the paint to dry. Then, reattach the leg to the table. http://www.alphafurnishings.com/

China Truck Manufacturing Writ Large As Global Trade Microcosm.
china truck Manufacturing Writ Large As Global Trade Microcosm.

This is my long-winded way of saying that though I am NOT an expert on worldwide truck manufacturing, I probably know that business better than any other.

And so, of course, I was very intrigued by a recent Financial Times article, entitled, “Chinese truck makers take on global groups,” on how “International truck makers are facing increasingly tough competition from Chinese commercial vehicle companies, which have already cornered the domestic market and are now aggressively moving on to the export market – especially south-east Asia and Africa.”

Chinese truck manufacturers are going to be puring profits from their sales in emerging markets into R&D that will allow them to up their quality to be able to go into North America and Europe.
Western truck manufacturers are moving into China to lower their costs to be able to compete in China and in emerging market countries, which in turn will expose their technology to Chinese companies, which in turn, will better enable Chinese companies to compete on a global scale.
I am seeing something else in China Truck manufacturing business that was not mentioned in the FT article: Chinese companies licensing American technology. No doubt, my firm’s background with trucks has caused us to see a disproportionate number of such licensing deals, but seeing them we are and they all have a common thread. A Chinese truck manufacturer has told its Chinese part supplier that it has x number of months to start giving the Chinese truck manufacturer a “world class” part and if the Chinese part supplier does not do that, the Chinese truck manufacturer will start buying that part overseas.

In response to this edict, the Chinese part supplier hunts down an American or European company that manufacturers the same part for a licensing or joint venture deal. I talked generally about this phenomenon in “Fear The China Joint Venture And Front-Load Your China Licensing Agreements.“

This same dynamic has already taken place and been completed in a whole slew of industries and I suspect it is ongoing in a whole slew of other industries. What are you seeing out there? http://www.cummins-china.net/

Dental Bearings
Dental Bearings
Dental bearings are smooth spheres that provide low resistance rolling action in dental handpieces. They can be made from a variety of materials including ceramics and stainless steel. Currently there are several different companies that standardize the construction of ball bearings. However, there are currently no federal requirements for standardization. If you are interested in dental ball bearings standards then you should contact the American Bearing Manufacturers Association.
The life of dental bearings depends on a lot of things. Generally they are designed for a long and active life. However, improper loading, calibrating, improper cleaning and handling and even excessive speeds can damage and wear out your dental bearings.
Proper care for dental bearings starts by proper cleaning. After you use your dental instruments, especially those with ball bearings, you need to sterilize them using an autoclave machine. By sterilizing your ball bearings you will remove bacteria and germs that can lead to patient infections, as well as remove debris from the ball bearings that can cause gauging, chipping and general degradation of the smooth bearing surface.
In addition to cleaning your ball bearings properly you also need to store your dental bearings properly. To store your ball bearings properly you will want to leave them in their originally packaging until you need them. The packaging is designed to prevent surface damage and to keep the bearings clean and sterile. General storage of your bearings should be done in an area that has a constant temperature and humidity level. You should also try to store them in an area of your office that is dry and cool.
There are a lot of supplies, tools and materials that dental practices need in order to operate properly. Some of the most important dental tools are dental bearings. These small tools are needed for dental handpieces to work properly. A smooth running dental practice requires the proper tools for every job including administrative tasks. Administrative tasks include things like setting up patients files, filing insurance forms for payment, managing costs and ordering supplies.http://en.lily-bearing.com/sitemaps/dental-bearings.htm

How To Clean Skateboard Bearings
How To Clean Skateboard Bearings
I m going to show you two ways to clean your skateboard bearings - a fast, easy way that is OK for your bearings, and a longer, more complicated way that is far better for your bearings, but takes a lot longer. You should clean your skateboard bearings if your bearings have slowed down, seem kinda mucky, or if they make a gravely, junky sound when you spin your wheels. To avoid getting to that point, you should really clean your bearings fairly often, even when they are only a little dirty, or just haven t been cleaned in a long time. Cleaning your skateboard bearings like this from time to time will increase your bearing s lifespan, and improve your skateboarding experience (translation - you ll have more fun!).
What you need:
First, you ll want to remove your skateboard bearings. You can clean your bearings without removing them, as I ll show you later, but you won t get them very clean that way. To clean your skateboard bearings well they need to have been removed from your skateboard wheels. Not sure how to do that? Pause for a second and read How To Remove Your Skateboard Bearings. It s quick and easy.
You also need some rags, towels or paper towels - this will get messy, so if you are going to clean your bearings in the living room of your house, make sure you put down a lot of towels. And, you might not want to wear your favorite clothes.
This is where things split between the quick and better cleaning methods. I recommend using the quick method if you have cheaper bearings ($20 or less), or if you plan on wearing your bearings out fast anyway. The problem with the quick method is that the cleaner contains surficants and perfumes that aren t the best for skateboard bearings. So, if you spent $50 or more on skateboard bearings, and want to keep your bearings as healthy as possible, use step 6, the "Best Method", listed below
But, for the rest of us, here s what else you need! I highly recommend Tri-Flow Superior Lubricant. You can pick it up at most hardware stores.
I like Tri-Flow because the spray nozzle makes it super easy to use, and Tri-Flow is designed to not leave any residue behind. do not, I repeat DO NOT use WD-40, or anything like it! WD-40, and other cheaper lubricants leave behind a film that actually collects dirt and dust. I used WD-40 on my very first set of skateboard bearings, long ago before I knew better, and they were dead in a month... The key is to clean your bearings with a lubricant made for it - you want the bearings lubed up, but you don t want any sticky film or residue left behind.
Now, here s where the "quick and easy" comes in. Hold the bearing, and using Tri-Flow, blast the snot out of it. Aim around the edges of the bearing, try to blast into every edge you find.http://en.lily-bearing.com/sitemaps/skateboard-bearings.htm

Can Granite Be Used Under Chairs With Metal Legs
Can Granite Be Used Under Chairs With Metal Legs

Not all metal chairs and materials are a threat to granite. Different types of natural stones have varying degrees of scratch resistance, ranging from tumbled marble on the low end with an easily scratchable surface, to granite tile, which is one of the hardest types of flooring material you can choose. Even so, granite can still be scratched, although it is extremely difficult to do so with something like chairs with metal legs.

Moh s Scale
The universal scale to test the hardness of a natural stone such as granite is known as the Moh’s scale, based upon the research put forth by mineralogist Frederick Moh out of Australia. The scale determines the hardness of a material by comparing the scratch resistance of one material to another, and is only used to define durability according to abrasive forces. According to Moh’s scale, any material that is higher on the scale will scratch something below it, but not vice versa.

The Hardness of Granite
Granite normally rates around a 6 on Moh’s scale, although it is usually grouped in with orthoclase and feldspar. It can be rated as a 7 if it includes particles of quartz. At a 6 on the scale, granite is one of the harder materials known, and while a knife will not scratch its surface, some items such as glass or quartz, will leave a mark.

Natural Flaws
As a general rule, the metal from chair legs will not scratch the surface of granite tiles due to the inherent abrasive resistance of the material. However, if there are natural flaws in the surface of the stone, such as a crack, there is the possibility that aggravated abrasion over the years will eventually cause slight scratching.

Exceptions to the Rule
You should be fine using chairs with metal legs on top of a granite floor, but the introduction of additional materials could cause scratching. For example if you break a drinking glass and the a tiny sliver of glass is caught under the edge of a metal leg and dragged across the surface of the floor, there will certainly be a scratch. http://www.alphafurnishings.com/
