The QSX15 power plant delivers impressive performance, capable of reaching 550 horsepower without requiring specialized software like other brands. Do you know when this engine was installed? The QSX engine builds upon the success of the QSK19 unit, featuring an updated design for improved efficiency. Ross
It appears that the engine was manufactured in March 2006. Based on that, I would assume that the re-powering process took place earlier this year. :cool2
In upgrading my 623E this spring, I opted for a tier 3 C15 engine. The modification required changes to the nose and cooling system to accommodate air-to-air aftercooling. The conversion utilized all 623 G parts from the transmission forward. The Cummins engine installation appeared well-executed, but it may impact the machine's resale value due to not being a Caterpillar brand. The horsepower rating of the C15 is comparable at 385, indicating similar performance capabilities. Overall, if the engine upgrade proves successful for the user, it is a commendable choice.
It's been a while since I've delved into engine work, but the QSX engine appears to be a new addition. The QSK19 was a unique blend of a Komatsu engine and a Cummins electronic system. Cummins continues to produce the powerful QSK19 engine. When Cummins integrated electronics into their "B", "C", and "M" series engines, they rebranded them as the ISB, ISC, and ISM models. The old 855 series engines were converted into N14s some years back when they were equipped with electronic systems.
When undertaking expensive projects like engine repowers, it's crucial to ensure that the machine is in good enough condition to warrant the investment. Often, if the engine is failing, the rest of the machine may not be far behind. While it may seem like a daunting task to tackle a single project, taking on multiple projects with shared costs can make it more economically viable.
Older scrapers like the 631 and larger models could be a cost-effective option if there are enough units to work on. Since these older engines are no longer in production and rebuilding them can be expensive, it may make sense to consider alternatives.
The 623 scraper, as indicated in my performance manual, was initially rated at 300 horsepower for the first model and 330 horsepower for the B and E models. The E models are equipped with a 3406 engine and may not require an upgrade to Tier 3 standards. It was mentioned that this information pertained to Riverside, likely referring to California. Does anyone have an estimate of the project cost?
In California, it's important to set aside common sense when considering a repower option as it can be a cost-effective alternative to upgrading to a tier 3 machine. New regulations are being implemented that will make tier 3 power mandatory, based on total horsepower and compliance dates. Many large contractors and rental companies are either opting for repowering or selling equipment with unregulated engines to meet the upcoming deadline. I was able to receive a 95% incentive from the air pollution control district for my 623 repower, which was too good to pass up considering the high time engine and impending regulation compliance. The horsepower on 623 E models was increased to 365 with the Super E upgrade to piston hydraulics. Hope this information is helpful for you. DP.
I am unsure of the exact amount, but I will definitely research and find out. ECCO has been consistently selling off outdated machines to modernize their fleet, and this re-powering project appears to be a first for them. Once I gather more information, I will be sure to share it with you. Stay tuned! :cool2
Thank you to both Petes for their responses. I have been hearing about the new regulations incurring significant costs, and this discussion confirms that. In Washington State, there is a push to have contractors replace 50% of all unregulated engines by 2011. Currently, this cannot be enforced due to a state law prohibiting government funding to private businesses. As a result, there are no incentives for private businesses to comply, at least not yet.
One approach that has been taken is that government construction contracts can now stipulate that only a certain percentage of machines with unregulated engines can be used on the jobsite. While there hasn't been much interest in repowering equipment in this area, it is likely just a matter of time before older machinery with unregulated engines are phased out through legislation. Are there any other thoughts on this issue?
What exactly is meant by "repower"? Initially, I assumed it meant rebuilding, but could it involve upgrades for emissions or entirely new engines? Are tier 3 engines just new models with reduced air pollution? The days of thick, black exhaust smoke lasting 9 seconds are now just a memory, though some may miss it despite its harmful impact on the ozone. Apologies for resurrecting old threads, as I am new to this community.
Yes, we are discussing the process of removing a motor and replacing it with a different environmentally friendly motor that complies with EPA regulations. Our first experience with this was around two years ago in 2005. This is my secondary occupation where I handle tasks such as equipment maintenance and repair. Monitoring employees is compensated at time and a half.
Moving on, we began updating our generator sets approximately three years ago. In 2005, we upgraded a GM671 engine to a new Caterpillar C9 in our decades-old drilling rig. The next step will be upgrading the mud pumps. Our homemade pump rig, powered by a Chrysler Hemi on propane, continues to operate efficiently.
During my initial project, we opted for a Cummins engine over a Caterpillar due to Cat's unavailability of a Tier 3 engine at the time. Cummins was a more cost-effective option at 65-75% of the cost of a Caterpillar, and it runs just as well if not better while consuming 10% less fuel.

Check out that beautiful vintage Hemi under the hood! I actually have a couple of them in my collection, powering my two 1956 Chrysler New Yorkers. Can't quite tell from this angle, but is it a 331 or a 354 cubic inch engine? These engines were truly groundbreaking, sparking a fierce competition for more horsepower in the mid-1950s and peaking in '71 and '72. The fact that the base block design was still being used until recently is a testament to the durability and performance of these engines. Even the beloved 318/5.2L MoPar engine traces its roots back to this iconic Hemi design.
I believe it may be model 331, though I am uncertain. I will investigate further tomorrow.
In California, there are likely numerous vintage hemi engines mounted on poles with air raid sirens attached. Have you ever heard of the infamous Victory Siren, known as the loudest man-made siren ever created? Check it out on the official website: http://www.victorysiren.com/x/index.htm. Explore the history and power of this iconic siren that continues to fascinate enthusiasts worldwide.
