Mercedes Fuel System Issues

Mercedes Fuel System Issues

The inline six Mercedes fuel injection pumps run in a fuel pressure rail that is designed to maintain a constant supply of fuel for the pump to inject to the engine, and cool and lube the pump in the none injection stroke as the cam shaft lobes run the pump. It is critical that the fuel is delivered without air and the system is air tight. Once air is introduced into the system the pumps become aerators and compound the problem, it is very similar to hydraulic cavitations; this will result in a hard start or no start condition, low fuel...

FUEL PSI. CUMMINS 5.9 LIFT PUMP

Posted by on Sep 6, 2013 in Tech Tips | 0 comments

Operating pressure for the fuel system of a 5.9 Cummins engine is critical. The lack or decrease in fuel pressure supplied to the injection pump is one of the most common reasons for injection pump failure. The system depends on fuel flow to cool and lubricate the high tolerance parts that make the pump work when it is starved for flow the pump overheats and fails. Unfortunately, the injection pump will continue to operate without the lift pump for a time. As the psi from the lift pump decreases the performance and life of the injection pump...

FUEL SYSTEM  C-15 CAT

One of the most common issues we see with the C-15 is erosion of the O-rings in the fuel system. If this is something that is occurring in your engine you will begin to lose mileage and performance; however, it may be so gradual you might not really notice. Some things you could notice in the early stages are: hard start after engine has been off for longer periods of time; over the weekend or overnight, when it starts; white/gray smoke, stumble or rough running for a short time then straightens up rest of the day. These are all symptoms of...

Electrical CHARGING?

Electrical CHARGING?

With today’s units on the road the electrical systems are more and more complex and vital to getting the performance you expect from your unit. However, the environment we operate in has not become any nicer. Calcium chloride is still our #1 problem in truck wiring systems. Bad connections and corroded wires create increased resistance in a circuit that at one time was not a big deal.  Today with multiplex and other systems resistance in a circuit is a major factor; as well as, proper voltage levels in maintaining proper operation. A major...

Lube Tips; Preventing Failures

Lube Tips; Preventing Failures

One of the most overlooked assets to your truck on the road today is the oil you run in it; unfortunately the old adage is still true, OUT OF SIGHT OUT OF MIND! In today’s engines, using the Hewy fuel injection system clean oil is more critical for long life and solid performance than ever before. Some of the oil systems firing the injectors of your engine are operating in as much as 4,000 to 5,000 psi in a hard pull. Such high psi creates more heat and with heat comes friction which means wear. As most know, oil does not wear out; however,...

The #1 reason for tire failure is under inflation!

Spring Time Tech Tip: The #1 reason for tire failure is under inflation! Most of the major tire companies have spent an enormous amount of time and money looking into why tires fail and all of them agree on the #1 reason!! A vast majority of the tires running up and down our Hwy are at least 10 psi short on the recommended inflation. “So what!” you say. Well, most of the large unwrapped treads you see on the shoulder are NOT recaps they are virgin tires that got too hot and came apart. A majority of the time when a cap blows you get all those...
