No matter how robust your Cat marine engine is, performance, fuel efficiency, and durability are rooted in the crankshaft performance. A state-of-the-art main engine is efficient enough to produce high-quality energy at regular intervals. Yet, if the crank fails to convert the reciprocating energy from the pistons into rotational motion, nothing else can move the propellers. Now you have all the reasons to relax as the Cat Reman crankshaft upgrade options keep your budget under control when buying the next new piece. Are remanufactured Caterpillar marine products any good? Here is an in-depth guide on remanufactured crankshaft upgrades for fleet owners using Caterpillar marine engines. The guide emphasizes the significance of choosing remanufactured Upgrade-to-New (UTN) crankshaft modules over new, more expensive items.

Crankshaft Repair or Upgrade – How to Determine

The majority of the crankshaft parts are replaceable. Hence, if the journals have failed or become damaged for some reason, there is an OEM replacement part available to restore the device to its perfect working condition. When should you upgrade to a new crankshaft and discard the previous one? All devices have a specific lifecycle. Suppose the crankshaft is working efficiently, but the bearings are chipped and producing noise. Upon diagnosis, the technicians may also identify a few other issues that have gone awry. Now calculate the cost of replacement parts. You can easily compare it to the price of the new piece. However, the Cat Reman crankshaft upgrade offers the possibility of purchasing a like-new item at affordable prices.

Benefits of Buying a Cat Reman Crankshaft

There are several reasons to opt for a Cat Reman Crankshaft upgrade when the old one needs replacement. Here is an overview of the advantages of choosing Cat remanufactured marine products at unbeatable price tags:

Compliant with MCS Standards

All vessel owners strive to install equipment that complies with international maritime standards. The good news is that all Cat Reman products, including the remanufactured crankshafts, abide by the standards of the Marine Classification Society (MCS). MCS regulations urge the vessel owners to install parts with identification information forged on the machine surface. All Cat Reman crankshafts and connecting rods have unique serial numbers and heat codes for traceability purposes, including details about the manufacturer.

Reliable and Durable – Same as a New Branded Module

Caterpillar is lauded for scaling newer heights in the remanufacturing criteria. While the company leverages materials extracted from used Cat products, the technology and product quality consistently impress users. The team goes beyond simple refurbishing or rebuilding machinery. Their top-tier engineers bring cutting-edge technologies to enhance performance, safe operations, and equipment durability.

Inexpensive Item with Warranty from the Original Manufacturer

All Cat Reman products are remanufactured in-house at designated Caterpillar's Reman facilities. These products undergo rigorous quality and performance testing before being introduced to the market for sale. Vessel owners investing in a Cat Reman Crankshaft upgrade for their watercraft receive the same 1-year comprehensive warranty as offered for any other new product. Moreover, the price is considerably low as 90% of the parts come from old and defunct modules. The reduced material cost, combined with less time and resources spent in the process, contributes to the affordable pricing structure. Furthermore, some items arrive preassembled in secure packaging — a surefire strategy to escape hours of downtime on fittings and labor costs.

Sustainability and Minimal Hazardous Wastes

Remanufacturing like-new devices from previously used machines is an eco-friendly initiative by Cat manufacturers. The team strives to maintain the lowest carbon footprint during the extraction of materials, the rebuilding of new items, and other procedures. Production units contribute to the rise of greenhouse gases when developing new complex equipment. A remanufacturing project involves minimal energy waste, allowing makers to build like-new items with greater speed and efficiency. According to research conducted by Caterpillar, GHG emissions and energy usage are 65%-87% lower during the remanufacturing process.

Less Toxic Wastes in the Landfills

Most traditional recycling agencies only scrap out the precious metals and frames from large marine equipment. The rest of the items generally mount up at the garbage sites. Cat remanufacturing units utilize state-of-the-art technologies to recycle up to 90% of the components and materials from old engines at the end of their lifecycle. Using materials from end-of-life machines and recycling waste reduces the burden of ever-mounting landfills.
