Testing is completed and the muffler system that replaces the reverse
flow mufflers used on the W-900L Kenworth and the International is now ready to
be installed on your truck. Why was
this system developed? The stock
muffler that is under the bunk of W-900L and IHC trucks is very restrictive, has
between 40 and 60” of backpressure, robs the engine of fuel mileage and doesn’t
allow the truck to run free. Its
impossible to obtain fuel mileage with a truck that has restrictive fuel, air or
exhaust flow. The new W-900L
muffler system is easy to install and you can do it in your driveway. Just remove the 2 stainless band clamps
that hold the existing muffler to the pipes, remove the 2 brackets that hold the
muffler to the chassis, and slide off the old muffler. Notice the weight of the old unit. It holds
soot.
Now all you have to do is clean the dirt off the Y pipe and also the pipe coming from the engine. Apply a little grease to the ends of the pipe so the new muffler and U pipe will slide on easily, install the 2 stainless band clamps and one 6” stainless band clamp to hold the U pipe to the muffler. Finally, install the 2 chassis brackets to hold the unit to the frame. You are finished and now have a free flowing straight through muffler. The truck will run free, the exhaust temperature will be cooler and the fuel mileage will improve.
This muffler is NOT as quiet as the stock unit. It can’t be because its free
flowing. However the noise at light
and moderate throttle is about the same.
Now, when your foot is into the throttle you will now know that something
is happening under your hood. Is
this bad to be able to hear the engine working? Absolutely not! When your tired and really not paying
attention to the gauges your ear will pick up the beautiful melody of your
engine.
Have you eve noticed that when you have a cold, food doesn’t taste the
same? That’s because you can’t
smell it and smelling it is part of the taste sensation. Well that goes for driving also. If you can’t hear your engine working
how can you drive it properly? Did
you ever wonder why racecar drivers wear thin-soled shoes? Its so they can feel the car through
their feet.
“THE BEAUTY OF A GARAGE”
Why do so many owner-operators continue to purchase new trucks when they
know the power is down and so is the fuel mileage? I’m told the main reason is a tax
write-off. So instead of purchasing the new truck why not build a garage and
equip it with the tools you will need to maintain and repair your truck. Its truck equipment so, it’s still a
write-off, and if your current truck is paid off why not take a couple days per
month to perform maintenance and do minor repairs. You will feel better towards your truck
when it’s your labor keeping her perfect.
Ron Kelsey, from Phoenix, Arizona is a prime example of an owner-operator that refuses to give up on his old Pete. His truck is a 1981 359 Peterbilt with just over 2,700,000 miles. Yes the truck has gone through several major changes and the last one has just been completed. Ron removed a Big Cam Cummins Engine and installed a 3406-E 550 hp. Caterpillar Engine. But he just doesn’t install an engine. Not Ron Kelsey! This engine is powder coated orange and has a lot of chrome. Frame rails and firewall always get repainted when he has an engine out of the chassis. This truck has been in the Las Vegas Truck Show many times and will be at the Louisville Truck Show this March.
