Clessie L. Cummins, founder of the Cummins Engine Company, drove across the United States to demonstrate the viability of diesel engines in 1931. While descending Cajon pass in California, the foundation brakes on his vehicle faded and he and the crew of his truck were nearly killed. Shortly after this experience Clessie first conceived the idea of using the engine to slow a vehicle going down hill.

There are many benefits to having a vehicle, or a fleet of vehicles equipped with Jake Brake retarders (whether they are the Jacobs Engine Brake? or Jacobs Exhaust Brake?). Here are a few... The use of Jake Brake retarders reduces the wear and tear on the service brakes, reducing the frequency of brake system service. Brake drum temperatures increase with use, and pads wear faster when hot.

A standard technology engine brake consists of a solenoid valve, control valve, and master and slave pistons. These components are assembled into a housing as shown below. When the brake is activated, the solenoid allows oil to pass to the control valve. The control valve moves up and the check ball in the control valve is unseated, allowing oil to fill the master/slave piston circuit.

There are different ways to check engine compressions, and they can reveal specific internal defects. A healthy engine should have all readings near mfr's spec, and should be about +/- 10% of each other. If not...you are in trouble. If one or more is low, but not adjacent cylinders (e.g. 1 & 3) suspect either a burned valve or worn rings. If adjacent cylinders are low, also suspect a bad head gasket or a warped head.

Jacobs Vehicle Systems is not developing an Engine Brake for these engines today. Typically engine brakes are applied to engines of 10.0-L displacement and higher. The Jacobs exhaust brake product is available for the Cummins B5.9, ISB, C8.3 and ISC engines. For more information about the Jacobs Exhaust Brakes for Cummins B and C engines, visit our Medium Duty Exhaust Brake Applications and Performance page, or our Exhaust Brakes for the Dodge Ram page.

Generally if your brake stopped working entirely, you have an electrical problem. This is most likely a failed switch (probably a fuel pump or clutch switch). You can usually confirm this by hot-wiring the brake, bringing battery power directly to the solenoid leads (with the engine at idle). Be sure to disconnect the existing leads to the solenoids so that you do not damage your control system. If the brake does not operate when hot-wired, you may have a solenoid failure.

North America: Most vehicles have an emissions decal placed either on the backside of the hood, on the radiator core support, or on the air box (the box that holds the air filter in place). Your engine size should be shown on the decal (4.0L for example). If you can't find the emissions decal you may also find the engine size printed on the decal under the hood that shows your engine's belt routing.

When compression is turned on, all communications other than the initial setup between a console and engine are compressed. The ZIP format is used for run-time compression. Compression rates will vary based on the data being compressed. If you transfer a saved capture file from the engine to a console, it will be compressed on the engine side and uncompressed on the console before saving locally. Running captures are not transferred en-mass from engine to console.

Well, a journey of a thousand miles begins with one small step and continues with many subsequent small steps. My homesite started from a small number of static HTML pages kept on the server of my workplace back then (Smart Link). It had the address http://www.smlink.com/~shlomif/, now disactive, where shlomif was my username on ibm.net back then (which ended up becoming my general unofficial ID).

Just so you know, the bro's at www.hondachopper.com combined have hundreds of years experience with the sohc honda 750cc motorcycle. and include several custom shop owners and private customizers among their membership. A pretty cool place to hang out!

All T&B Battery powered tools have a by-pass cartridge that relieves pressure when maximum output is reached. This is noted by a series of audible "clicks" followed by the tool running in "neutral" mode. The tool cannot be cycled again until the ram is released. It is not necessary to fully retract the ram. This will save on battery cycle life when crimping smaller wire.

Yes, the new manual transmission 24-valve engine was designed with the exhaust brake in mind. Replacement of the exhaust valve springs will not be required as it was on some models of the previous style engine. (Please note: Current 12-valve-compatible E Brakes designed for '89-'98 model Dodge Rams should not be installed on '98 and later 24-valve electronic engines. Doing so can cause serious damage to the engine.

No, Rislone Compression Repair is designed to only be used with conventional 4 stroke automobile engines.

Organic Streetbike Pads (i.e. "standard" compound) are the number 1 selling EBC formulation. They're made in EBC's own factory in Bristol, England. They are a Non Asbestos Organic compound featuring Dupont Kevlar? in conjunction with other high tech fibres that have come on the market. The NAO series are a superb all round value-for-money replacement for all levels of motorcycle and are still extremely popular with many riders who prefer the "feel" of organic pads.

The ONLY complete range of motorcycle discs. These are hub and rotor complete units ready to bolt directly to your wheels. The EBC Pro-lite series has become an aftermarket standard worldwide because of its very close similarity to the original disc but offering a higher friction (18% extra) braking power over stainless steel. They feature a safe, riveted, sturdy construction as opposed to the risky circlip system used by some other manufacturers.

Check the tool and die. A properly calibrated tool with the correct die minimizes installed error. Other guards such as T&B's Shure-Stake feature insure the tool has been run through its full range.

Several articles and examples are available to guide you in the construction and authoring a solid press release through this site. We've provided the USANews Helpdesk to assist you in writing your press release to comply with industry standards.

All rehabilitated animals are released in clean and oil free areas chosen by federal and state trustee agency personnel and IBRRC. If the area that they were captured in is still oiled then the animals are sometimes transported to more remote locations for release.

Starting December 1996 we plan to make intermediary releases every month or so, and "real" releases every three months or so. The 0.75 release was made available around December 11, 1996. In April 2000 0.90 was released. See versions.html for a list of all released versions.

Music files primarily come in two varieties: "compressed" and "uncompressed." An uncompressed music file is the music stored as faithfully as the computer can hold it, just like the music on normal audio CDs. These are large files and hold every scrap of data the computer needs to reproduce the music as closely as it can to the original recording. These files are often named with .WAV or .AIFF extensions.
