Detriot Diesel Rebuild kit

 

Detroit Diesel’s inline 6 cylinder Series 60 engine has been a success from the start of production in 1987. Available in 12.7L and 14L displacements, the Series 60 was the first heavy-duty diesel engine with fully integrated electronic controls in the world, and with the evolution of its electronic controls, it’s still the leader. The Series 60 engine is the most popular heavy-duty diesel engine in the truck market for 12 years in a row. The overhead camshaft and cylinder head design not only maximizes engine power and performance, but optimizes fuel economy too. The Series 60 has also successfully crossed over into the off-highway markets. The Series 60 delivers up to a maximum 825 horsepower and is available for Truck, Bus, Construction & Industrial, Gen Sets, and Marine applications.

What are the most popular Detroit Diesel engines?

The easiest way to categorize Detroit Diesel engines is by classifying them as “2 Cycle” or “4 Cycle” engines.  A 4 cycle or 4 stroke engine is an internal combustion engine in which the piston completes four separate strokes—intake, compression, power, and exhaust—during two separate revolutions of the engine’s crankshaft, and one single thermodynamic cycle. Below is a list of the most popular Detroit Diesel “4 Cycle” engines:

  1. Detroit Diesel Series 60 (S60) engine 6 cylinder In-line (11.1, 12.7 & 14L)
  2. Detroit Diesel Series 50 (S50) engine 4 cylinder In-line (8.5L)
  3. Detroit Diesel Series 40 (S40) engine 6 cylinder In-line (6.7, 7.6 & 8.7 L)
  4. Detroit Diesel Fuel Pincher engine 8 Vee (8.2 L)

A two-stroke or two-cycle engine is a type of internal combustion engine which completes a power cycle in only one crankshaft revolution and with two strokes, or up and down movements, of the piston in comparison to a “four-stroke engine”, which uses four strokes to do so. This is accomplished by the end of the combustion stroke and the beginning of the compression stroke happening simultaneously and performing the intake and exhaust (or scavenging) functions at the same time. Below is a list of the most popular Detroit Diesel “2 Cycle” engines:

  1. Detroit Diesel Series 53 engines: 2-53, 3-53, 4-53, 6V53, 8V53
  2. Detroit Diesel Series 71 engines:  2-71, 3-71, 4-71, 6-71, 6V71, 8V71, 12V71, 16V71, 20V71
  3. Detroit Diesel Series 92 engines: 6V92, 8V92, 12V92, 16V92
  4. Detroit Diesel Series 149 engine 8V149, 12V149, 16V149, 20V149

Facts About the Duramax Diesel
Oct 2015 21

If you are driving a heavy duty truck from GM or Chevrolet, there is a fairly good chance that you have a Duramax Diesel under the hood. These engines represent an extremely popular line of diesel engine products, produced by General Motors. Both GMC and Chevy heavy-duty trucks utilize these 6.6L V8 engines, which offer three-hundred-and-sixty-five horsepower, as well as six-hundred-and-sixty-five pound-feet of torque.

Second only to Ford’s Powerstroke, this diesel engine is well-reviewed and popular for a number of reasons. There are some fascinating facts behind this diesel engine, as well as something interesting historical tidbits. In other words, there is a lot under your hood, if you have a Duramax.

About The Duramax Diesel
The Duramax diesel was first introduced to the market with a 6.2L displacement. The 6.5L followed soon thereafter. Below are a variety of interesting pieces of information about the Duramax Diesel:

• The current 6.6L Duramax was first announced towards the end of ’98, as a collaborative venture between GM and Isuzu. The project was largely designed to create a viable improvement over the 6.2L and 6.5L, which had failed to find the degree of popularity that GM had been hoping for.
• At present, there are six versions of the Duramax 6.6L. The 7th is slated for release at some point in 2017. The versions produced thus far include LB7, LLY, LBZ, LMM, LML, and LGH.
• 7.8L and 2.8L Duramax engines are also available.
• If you are curious as to which Duramax is under the hood of your truck, finding out is as straightforward as checking out the 8th digit of your VIN number.
• The reason as to why there have been so many different versions of the Duramax is simple. Improvements have been made to not only embrace emissions, but to also take advantage of improvements that will allow vehicles to remain competitive.
• Contrary to popular belief, the aluminum cylinder heads of the Duramax do not cause a significant degree of problems. These cylinder heads have scored big in the reliability department over and over again.
• DEF refers to diesel exhaust fluid, which deals in the component known as urea. This element is crucial, in terms of allowing the SCR to transform nitrous oxides into comparatively safer elements. You may want to familiarize yourself with the Duramax LML Emissions System Overview.
• All Duramax engines include engine block heaters.

These are some of the basic facts you want to keep in mind.

Posted In Engine Rebuild Kit

When you have one of our John Deere 4020 Engine Overhaul Kit in your corner, you’re going to be in a much better position to ensure your John Deere 4020 tractor stands the test of time. This is a tractor that has been the backbone of American farming for several decades.

In other words, if you own a John Deere 4020 tractor, you own something that you can rely on for years to come. When the time comes, having a complete John Deere 4020 Engine Overhaul Kit will help ensure your 4020 tractor is reliable and productive with every use.

Facts About the John Deere 4020 Tractor
The story of the John Deere 4020 tractor can be traced back to 1963. It was in this year that the tractor was first released to the American public. It became popular almost overnight. Before this tractor was released to the market, smaller farms throughout the country struggled to keep up with the larger ones. Thanks to the John Deere 4020, these smaller farms had a vehicle that could pull a disk and planter simultaneously while baling alfalfa and hay. During the harvesting period, it could then be used to bring along the baler, baler ejector, and even the receiving wagon, all at the same time. Being able to perform multiple tasks concurrently gave farmers working with less resources and manpower more time and energy to focus on other things.

The John Deere 4020 enjoyed a production period that lasted eleven years. Roll-guard safety features were added to the tractor in 1966, which quite literally changed the safety value of tractors forever. Before long, John Deere not only added this feature to everything released through the “New Generation” run, but they made the patent available to all tractor companies.

In terms of features, the 4020 brings a lot to the table, including power front-wheel drive. In addition to this, the longer rear-axel allows for an additional set of wheels to be attached with ease. This dual-wheel system makes it easy for farmers to utilize alternate spacing for their wheels, depending on the width of a particular crop row.

Presently, the 4020 is a six-cylinder engine product that combines the row-crop and standard tractors of the past. It is a marvelous combination of John Deere’s ingenuity and commitment to excellence. With a John Deere 4020 Engine Overhaul Kit, you will be able to rely on the tractor for many years to come.

The Difference between Old Style and New Style Detroit Diesel Series 60 Non EGR
Nov 2015 04

When discussing engines, it is important to know that they are the heart of your vehicle. The Detroit Diesel Series 60 Non EGR has been used in large motor vehicles such as 18-wheelers and transport buses for many years. As time has progressed, the engines became more reliable and more affordable to fix with the help of after-market parts. Below are some of the most prevalent differences between the old and new style Series 60 engines.
DDEC I to DDEC IV
To improve the performance and response of diesel engines, they have been governed by various electronic control modules (ECM) throughout the years, starting with the Detroit Diesel Electronic Control or DDEC I and ending with the DDEC IV. The first system, DDEC I, lasted from 1987 to 1992, when it was replaced by DDEC II. All Old Style Series 60 11L & 12.7L engines were controlled by DDEC I, II or III until 1998. In 1999 the New Style Series 60 engine was introduced with a new ECM, DDEC IV. This new, more advanced ECM is one of the major differences between the Old Style and New Style Series 60 12.7L engines. The new ECM allowed for greater control through the use of more engine sensors. The other major change was a new, more durable two piece piston design with a steel crown and aluminum skirt capable of handling more horsepower. By 2001, the Series 60 14L New Style engine was introduced and offered large vehicles a 14L displacement option. The power was increased by up to 575hp and 1850 pounds of torque. This is all because of a large stoke crankshaft being installed.
Reliability and Longevity
The main difference that truck operators will notice between the older, mechanical diesels and the electronic engines of today is their fuel efficiency, reliability and longevity. Even though many believe that things were built better in the past, the newer style engines like the Series 60 have upgraded components designed and built to last an extended period of time. Since trucks now spend many hours on the road, manufacturers are held to higher standards for their engines. Many users find that the Detroit Diesel Series 60 engine is the most reliable engine of all. Lightweight, fuel efficient and great for hauling anything.
Technological Components
When installing a newer electronic engine it is essential that you have a computer and the appropriate software that will help you optimize it, whereas in the past a computer interface was not needed. These programs help to run diagnostic checks of every part of your engine to make sure that it is working efficiently and to its best standard. If not, it will show you what part of the engine needs to be taken care of.

Sneak A Peek at the John Deere 13.5L Power-Tech PSX 6135Comments Off on Sneak A Peek at the John Deere 13.5L Power-Tech PSX 6135

Posted In Engine Rebuild Kit,Heavy Duty Kits

The John Deere Power-Tech PSX 6135HFC95 is an inline six-cylinder 13.5L (824ci) diesel engine capable of generating 617 horsepower at 1,900 rpm and a torque of 1,962 ft-lbs at 1,600 rpm. With a 5.20×6.50” bore and stroke, single overhead camshaft, valve train with four valves per cylinder, a compression ratio of 15:3:1, a sequential fixed and variable-geometry turbochargers induction system, electronic unit injection at 33,000 psi and air to air inter cooler, this engine is in the forefront of diesel technology. The engine requires an oil change every five hundred hours. The head material is cast gray iron alloy while the block material is cast gray iron. The crankshaft material as well as the camshaft is forged steel. The engine is just over five feet in length and a tad more than three feet in width. It is five feet high and weighs 3,699 pounds or 1,678 kilograms. The engine has a cooled exhaust gas re circulation system, diesel particulate filter and oxidation catalyst as its emission system. It complies with the emission norms of EPA Interim Tier 4, CARB and EU Stage III B.

What stands out in the engine is the low-pressure fixed turbo and a high-pressure variable-geometry turbo working in sequence, the one-piece cast design using a heavy-duty, gray iron alloy material, the high-carbon steel camshaft with induction-hardened lobes to reduce noise and to increase life and the full-floating steel pistons with crankshaft of high carbon forged steel that can resist extreme heat and offer precise alignment. The attention to detail makes this engine a wonder.

Modern emission standards have been getting stricter by the day. Power or high performance is thus an expensive or an elusive attribute. The Power-Tech PSX 6135 smartly uses a cooled exhaust gas re circulation, a powerful injection system, a substantially large diesel particular filter and a diesel oxidation catalyst to adhere to the emission standards. The 13.5L Power-Tech PSX 6135HFC95 is a victory of industrial design and engine architecture. It is needless to say that the engine has already found numerous takers in the world of fire pumps and oilfield drills.

A Guide to Overhaul Duramax LB7 Injectors
Dec 2015 03

The Duramax engine is one of the finest ever to have been made for pickup trucks. But even the best can have a few faults. The original Duramax engine that rolled out back in 2001 and every variant that rolled out in the subsequent three years have a serious flaw. The fuel injectors are not among the sturdiest. The injectors have a substantial chance of failing, much before a hundred thousand miles. Should the LB7 injectors fail, they can leak substantial amount of fuel and dump it into the engine. This can happen when you are driving but also when your truck is idle. If the excess fuel leaked doesn’t get burned, then it can affect the oiling system and the engine will start to get filled with diesel. That is definitely not something you want!

While GM has offered an extended warranty to cover up to two hundred thousand miles, the injectors failing can be a bummer! LB7 injectors are pricey and they cannot be replaced unless one is very well trained. The injectors are so hard to reach that most people wouldn’t even be able to get to them, much less replace them.

When should you replace Duramax LB7 Injectors?

You must be observant of signs that your LB7 injectors have failed or have worn out. You may notice white smoke. Be careful because white smoke can also be a symptom of coolant loss or oil seeping into the radiator. But usually, white smoke is considered to be a cause of LB7 injectors’ failure in Duramax engines. Get your truck to a technician and one can test the balance rates of the injectors to know for sure if they must be replaced.

How to overhaul or replace Duramax LB7 Injectors!

First, the intake has to be removed. Then one must remove the fuel filter along with the housing and lines. One would then get access to the valve cover. The fuel injection control module has to be removed. It is typically mounted on the valve cover at the passenger side. There are several electrical and rubber connections that must be removed. Then you would get to the injector line. Take out the lower and upper valve covers and you would have access to the injectors.

The next steps involve removing the electrical connections, taking out the injector return line and then removing the injectors. You may need an injector puller for the job. Once the injectors in need of replacement are removed, new ones can be installed.

Debunking 5 Popular Myths about Diesel Engines

Debunking 5 Popular Myths about Diesel EnginesComments Off on Debunking 5 Popular Myths about Diesel Engines

Posted In Diesel Engine

Diesel engines have been very popular in commercial vehicle but when people consider buying a personal car, the preference is inevitably the alternative. Diesel engines have become infamous over time but mostly because of certain myths that have remained firmly etched in our minds. It is necessary to debunk these myths. The focus on fuel economy and cost of running a car has ensured that people are getting interested in diesel engines. Time to shed light on a few facts and misconceptions.

  • A popular myth is that diesel is a dirty fuel and that vehicles powered by diesel engines will emit toxic exhausts and particulate matter. It is quite interesting to observe such myths because the EPA emission restrictions are very stringent and they don’t make any exceptions for diesel engines. Diesel powered cars have to adhere to the EPA restrictions so any thought that diesel cars will pump out more harmful gases and particulate matter than gasoline cars is just a figment of imagination. Also, cars today don’t emit the visibly black, white and grey dense smoke unless something is wrong.
  • There is another popular myth that diesel engines will go kaput when the mercury dips. This is a presumption that couldn’t be farther from the truth. There was a time when gasoline cars also didn’t start when it would be freezing outside. The trouble is not with the fuel. The problem is with the engine. Today, technology has ensured that diesel engines can have a cold start. It is true that gasoline is more flammable than diesel but vehicles don’t just start due to the fuel. The engine and the ignition technology play a role too.
  • Diesel engines are feared to be very noisy, sluggish and that they would lack in performance. This perception has developed from the fact that diesel engines have been primarily used in commercial vehicles, aka trucks and buses. Those vehicles are tilted towards viability and not comfort or exuberance. The diesel engines used in cars don’t have the same issues. The focus is on comfort, speed, quietness and all the attributes that one wants in a personal car.
  • Another myth is simply a misconception. That is that diesel fuel is hard to find. Nowadays most gas stations supply both gasoline and diesel.
  • Many people feel that diesel is more expensive. Some diesels can be more expensive than gasoline but most are not.
