The year was 1939. T.A Peterman leaves the logging industry after finding an interest in buying excess trucks from the Army and rebuilding/improving them for heavy hauling. He bought a failed Fageol Motors, turning it into, well you guessed it, Peterbilt. The first few truck models that Peterman came out with were Model 334 and Model 260. Both of these were known for their all-steel cab. When WWII started, Peterbilt focused on bringing their expertise in trucking to help out their country by creating Model 364, which was known for being a dependable workhorse. T.A was unfortunately only able to enjoy his success for five short years until he passed away in 1944; a year before the war ended. His wife sold the company to a handful of managers.
Once the war ended, Peterbilt had new goals to reach.

1954 comes and introduces Model 351, becoming the longest production in Peterbilt history! It was then that the Peterbilt’s Red Oval logo was made. It was in 1958, that the Pacific Car & Foundry, who later changed their name to PACCAR, purchased Peterbilt, starting a relationship that has lasted for 60 years (and still going).  The 1960s was a period of innovation for Peterbilt. One of the biggest changes was Model 352. The 352 switched to a lightweight aluminum cab and had a 90-degree tilt UniLite cab. The next big addition was made on Model 358 with the addition of the Peterbilt bird hood ornament.

 

Why Should You Have Your DPF/DOC Cleaned?

When left uncleaned, soot and ash will collect and could damage or destroy you filter. While soot and ash burn off as quickly as it accumulates when driving under load, it tends to accumulate and stay when idling or driving through slow-moving traffic.
A few key indicators that it is time for a professional cleaning are a loss in engine performance or an increase in frequency in regeneration cycles. With regular DPF cleanings you could see:

    Increased fuel efficiency
    Extended filter life
    Higher resale value if you decide to sell your truck at some point

A dirty filter may not sound like it could cause a lot of damage if left unattended, you’d be surprised by how costly it could be. This makes cleaning a necessary part of maintenance. When you factor in that replacements cost about $3,000, if not more, plus the cost of unexpected downtime, neglecting this relatively simple process could greatly affect your bottom line.

The Importance Of Cleaning Diesel Filters

When was the last time you had your diesel particulate filter (DPF) or diesel oxidation catalyst (DOC) cleaned? If the answer is, “I don’t know” and your truck is newer than a 2007 model, it is time to visit a repair shop. If your diesel engine is newer than 2007, here are a few things you should know to extend your filter life and increase your fuel efficiency.
What Does a Diesel Particulate Filter or Diesel Oxidation Catalyst Do Exactly?
Before we go into detail on why you need to clean your DPF and DOC, we need to discuss how these engine components work together. The DOC protects the DPF. Vapor can interfere with the DPF’s ability to trap and remove particulate matter, so manufacturers route the exhaust through the DOC first, then into the DPF. The DOC forces the exhaust over a honeycomb ceramic structure coated with catalyst which chemically changes carbon monoxide and hydrocarbons to carbon dioxide and water. Then the exhaust gases go through the DPF where it is forced through porous channel walls, trapping and holding the remaining ash and soot.
When Is It Time To have Your DPF or DOC Cleaned? A good rule of thumb is to go in for a cleaning about every 200,000 miles or less depending on your duty style. It is possible to burn off this excess ash and soot on your own using either passive or active regeneration. Passive generation uses the normal exhaust temperatures and nitrogen dioxide to oxidize the build up and active regeneration requires much higher temperatures. Even with these different cleaning cycles, it is still important to take your truck to get serviced.
