Finding Older Cummins Parts for the 1987 855 Cubic 300 HP Balancer

[MikePhua]

When it comes to maintaining and repairing older heavy-duty machinery, finding the right parts can often feel like a challenge, especially when the equipment in question is several decades old. For those operating vintage engines like the 1987 Cummins 855 Cubic 300 HP Balancer, sourcing specific components can be even more difficult. However, with a little knowledge and persistence, it's possible to find the necessary parts, even for older machines.
The Challenges of Sourcing Parts for Older Engines
Older engines, especially those from well-known manufacturers like Cummins, often present challenges when it comes to sourcing replacement parts. The Cummins 855 engine, known for its durability and reliability, was widely used in a range of heavy equipment during its time, including construction machinery, trucks, and agricultural equipment. However, over time, parts wear out, and as manufacturers introduce newer models, older components can become increasingly difficult to find.
The Cummins 855 is a 6-cylinder, 14-liter, turbocharged engine known for producing 300 horsepower, and was commonly used in various applications from the 1980s. While the engine itself may be durable, components like the balancer, which is responsible for reducing engine vibration, can fail over time. The need for these parts often becomes more pressing as machines reach the point where repairs and maintenance are no longer easily carried out with off-the-shelf components.
Understanding the Balancer and Its Role
The balancer in an engine plays a crucial role in ensuring smooth operation by reducing vibrations caused by the engine’s moving parts. In the case of the Cummins 855 engine, the balancer helps prevent undue stress on the engine components, ensuring longer service life and better overall performance.
When the balancer fails or begins to show signs of wear, it can lead to several issues, including excessive engine vibration, premature wear on other engine components, and even engine failure if not addressed. For a machine operator or fleet manager, addressing a failing balancer is crucial to maintaining the engine’s performance.
Where to Find Older Cummins Parts
Finding replacement parts for older engines can be difficult, but it’s far from impossible. The key to success lies in knowing where to look and how to approach the process. For those looking for parts for the 1987 Cummins 855 engine, here are several approaches to consider:
1. Salvage Yards and Recyclers
Salvage yards are one of the most reliable sources for older engine parts. Many yards specialize in heavy-duty equipment and have a wide variety of parts from machines that are no longer in service. These parts are often removed from old machines that have been decommissioned or scrapped, and they are typically priced lower than new components.
In the case of the Cummins 855 engine, salvage yards that deal specifically in Cummins or other diesel engine parts may have the balancer and other hard-to-find components. It’s important to inspect the condition of these parts carefully to ensure they are still in working order.
2. Cummins Dealers and Authorized Distributors
Even for older models, Cummins dealerships and authorized parts distributors may still carry certain components, including those for the 855 engine. While it might not be easy to find specific parts like a balancer in stock, they can often order them or direct you to specialized suppliers that handle older parts.
Reaching out directly to Cummins can also provide valuable insight into any replacement options or upgrades that could be applied to older engines, which might make finding the correct part easier.
3. Online Marketplaces
In recent years, online marketplaces have become a valuable resource for finding hard-to-source engine parts. Websites like eBay, Craigslist, and specific forums dedicated to heavy equipment may have listings for parts like the 855 engine balancer. Many sellers on these platforms specialize in hard-to-find components and might be able to offer used or refurbished parts.
However, it’s critical to ensure that the seller is reputable and that the parts are in good condition. In some cases, sellers may offer a warranty or return policy, but it’s essential to verify before making a purchase.
4. Aftermarket Parts Suppliers
Aftermarket suppliers, which manufacture parts that are compatible with specific engine models but not produced by the original manufacturer, can also be a reliable source for replacement parts. While aftermarket parts can sometimes be more affordable than OEM (Original Equipment Manufacturer) parts, it’s important to ensure they meet the same quality standards.
For an engine as popular as the Cummins 855, many aftermarket suppliers offer replacement components, including balancers. However, always check the reputation of the supplier and ensure that the parts are backed by a warranty or guarantee.
Potential Issues and Considerations
While sourcing older parts for engines like the Cummins 855 can be rewarding, it does come with its challenges. Below are some key issues and considerations to keep in mind during the process:
1. Quality and Compatibility
One of the primary concerns when sourcing older parts is ensuring that the parts are compatible with the engine model and meet the necessary quality standards. If you’re buying used or salvaged parts, inspect them thoroughly or have a professional do so to avoid purchasing damaged or worn-out components.
2. Cost of Replacement
While older parts may not always be expensive, some components for vintage engines can come at a premium due to their rarity. Balancers and other critical engine parts may be more costly than expected, particularly if they’re no longer in production. Additionally, shipping costs can add up, especially if parts need to be sourced from overseas.
3. Long-Term Maintenance
When purchasing parts for older engines, consider the long-term maintenance of the machine. Even with replacement parts, older engines may experience ongoing wear that can result in higher repair costs over time. It’s essential to balance the upfront cost of repairs with the potential for future maintenance needs.
The Importance of Maintaining Older Engines
Older engines like the Cummins 855 have built a reputation for reliability, and many machines that feature these engines continue to operate successfully today. However, as with any piece of machinery, proper maintenance is essential to prolonging their life and ensuring they continue to perform at their best.
For operators of older equipment, regular inspections, routine maintenance, and sourcing reliable replacement parts are critical steps in keeping machines running smoothly. By investing time in finding the right parts, including balancers, engine components, and hydraulic systems, businesses can maximize the lifespan of their equipment and avoid costly downtime.
Conclusion
Sourcing parts for older machinery like the 1987 Cummins 855 engine requires persistence, resourcefulness, and a willingness to explore multiple avenues. Whether it’s through salvage yards, authorized dealers, online marketplaces, or aftermarket suppliers, there are options available for finding the necessary components. With careful consideration and attention to detail, operators can continue to get reliable performance from their vintage equipment for years to come.
The process of sourcing these parts not only ensures the ongoing functionality of these older engines but also highlights the lasting value of well-built machines like the Cummins 855, which have earned a place in the hearts of heavy equipment operators around the world.
