Review KUBOTA Breather Tube fits RTV-850 2018

The **Kubota EG673-52290 2018 RTV-XG850 Breather Tube** is a precision-engineered component designed specifically for Kubota s diesel-powered engines, ensuring optimal performance, longevity, and reliability in demanding agricultural, industrial, and commercial applications. This high-quality breather tube is part of Kubota s **RTV-XG850** series, a specialized rubber compound formulated to withstand extreme temperatures, harsh environmental conditions, and continuous exposure to fuel vapors, oil mist, and airborne contaminants. Crafted from **resilient synthetic rubber**, the tube features a reinforced construction that prevents kinking, cracking, or degradation over time, even under the stress of repeated engine cycles or vibrations common in heavy-duty machinery. Its **tight-fitting, interference-free design** guarantees a secure seal between the engine s breather system and the air filter housing, minimizing air leaks that could compromise engine efficiency or lead to premature wear on internal components. Ideal for Kubota s **V-twin diesel engines** such as those found in tractors, generators, and pressure washers the breather tube plays a critical role in maintaining proper crankcase ventilation, reducing carbon buildup, and extending the life of critical engine parts like the PCV (positive crankcase ventilation) system. Whether installed in a **2018 Kubota L3900, M7000, or other compatible models**, this breather tube ensures smooth operation, reduced emissions, and adherence to Kubota s stringent performance standards. Built to Kubota s exact specifications, it is a direct-fit replacement, eliminating the need for modifications or adjustments, and is backed by the brand s reputation for durability and engineering excellence.

### **Pros and Cons of Buying a Kubota EG673-52290 (2018 RTV-XG850 Breather Tube)**

1. **Reliable Brand Reputation** Kubota is a well-established manufacturer known for durable and dependable agricultural and industrial equipment. Their engines are often favored for longevity and performance in demanding conditions.

2. **Proven Engine Performance** The EG673 engine is part of Kubota s proven line of diesel engines, designed for efficiency and power. It is commonly used in tractors, generators, and other heavy-duty applications, suggesting it is built to last under consistent use.

3. **Compatibility with Aftermarket Parts** Kubota engines are widely supported by the aftermarket, meaning you ll have easy access to replacement parts, filters, and accessories. This reduces downtime and repair costs over time.

4. **Fuel Efficiency** Kubota engines are generally optimized for better fuel economy compared to some competitors, which can save money on operational costs, especially for frequent or heavy-duty use.

5. **Resale Value** Kubota equipment tends to hold its value better than some other brands, making it a more attractive option if you plan to sell or trade it in the future.

6. **Breather Tube Upgrade (RTV-XG850)** The RTV-XG850 breather tube is a high-quality silicone-based sealant designed to prevent leaks, reduce moisture ingress, and improve engine longevity. This upgrade can help maintain optimal engine performance and prevent premature wear.

7. **Lower Maintenance Costs (Compared to Some Alternatives)** Kubota engines are known for requiring less frequent and less costly maintenance than some other brands, particularly in terms of oil changes and filter replacements.

8. **Versatility** The engine can be used in various applications beyond tractors, such as generators, pumps, or industrial machinery, giving it flexibility if your needs evolve.

1. **Potential for High Initial Cost** Kubota engines, especially well-maintained or upgraded units like this one, may come with a higher upfront price compared to generic or less reputable brands. This could be a barrier if you're operating on a tight budget.

2. **Limited Availability of New Parts** While aftermarket support exists, some specialized or older Kubota parts may become harder to find over time, particularly if the engine is no longer in mass production. This could lead to delays in repairs.

3. **Complexity of Maintenance** Kubota engines, like many diesel engines, require regular maintenance such as oil changes, filter replacements, and fuel system cleaning. Neglecting these tasks can lead to costly breakdowns.

4. **Depreciation Over Time** While Kubota holds value better than some brands, all equipment depreciates. If you plan to use the engine for a short period or in a high-wear environment, the depreciation may outweigh the initial investment.

5. **Noise and Vibration** Diesel engines, including Kubota s, can be noisy and generate vibration, which may be a concern if the engine is installed in a residential or noise-sensitive area.

6. **Fuel and Emissions Regulations** Depending on your location, you may need to comply with strict emissions standards. Older engines (like this 2018 model) may require aftermarket modifications or filters to meet current regulations, adding to the cost.

7. **Potential for Hidden Issues** Even with a breather tube upgrade, the engine may have underlying problems such as wear on internal components, fuel system clogs, or electrical issues. A thorough inspection by a mechanic is recommended before purchase to avoid unexpected repairs.

8. **Training and Expertise Required** Operating and maintaining a Kubota engine effectively may require some training, especially if you're not familiar with diesel engines. Improper handling can lead to damage or reduced performance.

The **Kubota EG673-52290 (2018) with an RTV-XG850 breather tube upgrade** is a solid choice for those seeking a reliable, high-performance diesel engine with a strong reputation for durability. The breather tube upgrade adds an extra layer of protection against leaks and moisture, which can extend the engine s lifespan. However, the decision to purchase depends on your budget, intended use, and long-term maintenance capabilities.

If you plan to use the engine in a **heavy-duty, long-term application** (e.g., farming, industrial machinery, or a generator for extended periods), the pros such as reliability, fuel efficiency, and aftermarket support likely outweigh the cons. The breather tube upgrade further enhances its value by reducing the risk of internal damage.

If, however, you are on a **tight budget, need short-term use, or lack experience with diesel engines**, the higher upfront cost and maintenance requirements may make this purchase less ideal. In such cases, a used but thoroughly inspected engine from a trusted seller or a slightly newer model with warranty coverage could be a better alternative.

---

- You need a **durable, efficient, and long-lasting engine** for demanding applications.

- You are prepared for **regular maintenance** (oil changes, filter replacements, etc.).

- You have access to **reputable mechanics** for inspections and repairs.

- You plan to **use it for an extended period** (e.g., farming, industrial work, or a permanent generator setup).

- You want a **brand with strong resale value** and aftermarket support.

- You are operating on a **very limited budget** and cannot afford potential repairs.

- You lack **experience with diesel engines** and cannot commit to proper maintenance.

Before purchasing, **have the engine inspected by a Kubota-certified mechanic** to check for internal wear, fuel system health, and any existing issues.

If concerns arise during inspection, negotiate the price or seek an alternative.
