Review V TWIN MANUFACTURING New Tappet Oil Screen Kit And Chrome Top Plug Harley davidson Shovel fits 1981–1984

The **V-Twin 12-0152 Tappet Oil Screen Kit with Top Plug** is a meticulously engineered aftermarket upgrade designed specifically for Harley-Davidson s classic **81-84 Shovelhead** engines, ensuring optimal performance, longevity, and reliability for this iconic big-twin powerplant. This kit is a precision-crafted solution tailored to address the inherent challenges of the Shovelhead s valve train system, where oil flow and debris filtration are critical to maintaining smooth operation and preventing premature wear. The **12-0152 Tappet Oil Screen** is a high-quality, finely woven stainless steel mesh filter that replaces the stock oil screen, significantly enhancing the engine s ability to trap fine metallic particles, carbon deposits, and other contaminants that can accumulate over time. By capturing these abrasive particles before they circulate through the oil passages, this screen drastically reduces the risk of valve train wear, tappet damage, and overall engine degradation, allowing the Shovelhead to maintain its legendary durability with minimal maintenance hassle.

Complementing the oil screen is the **Top Plug**, a carefully machined and heat-treated component that seals the oil passage at the top of the cylinder head, preventing oil leaks and ensuring a secure, leak-free connection. Crafted from high-grade materials, this plug is designed to fit seamlessly with the stock hardware, offering a reliable alternative to the stock part while maintaining compatibility with the engine s original specifications. The combination of the upgraded oil screen and top plug creates a robust defense against oil contamination, allowing the Shovelhead s pushrods, rocker arms, and valves to operate with greater efficiency and longevity. This kit is particularly beneficial for riders who push their Shovelheads hard, whether through high-performance modifications, extended cruising, or heavy-duty towing, as it provides an extra layer of protection against the inevitable wear and tear that comes with time and use.

Installation of the **12-0152 Tappet Oil Screen Kit** is straightforward, requiring only basic hand tools and a bit of patience to ensure a proper fit. The screen is designed to drop into place over the existing oil passage, while the top plug is simply pressed into its designated hole, often requiring a slight tap with a rubber mallet to achieve a tight seal. Once installed, this kit operates silently and seamlessly, working behind the scenes to keep the engine s internal components clean and well-lubricated. Beyond its functional benefits, the kit also serves as a subtle yet meaningful upgrade for enthusiasts who appreciate the finer details of their Shovelhead s maintenance. Whether you re restoring a classic bike to its original glory or pushing it to new limits with aftermarket modifications, this kit is an essential addition to any serious owner s toolkit, offering peace of mind with every mile ridden.

### **Pros and Cons of buying a V-Twin 12-0152 Tappet Oil Screen Kit (Top Plug) for a Harley-Davidson 81-84 Shovel**

1. **Improved Engine Protection** The oil screen kit helps filter out contaminants (metal particles, debris, and sludge) that can damage critical engine components like tappets, bearings, and camshafts. This extends the lifespan of your engine and reduces wear over time.

2. **Prevents Tappet Wear** The original Shovel models (81-84) were known for tappet wear due to their design and oil flow. The screen kit helps capture debris before it reaches the tappets, reducing the risk of premature failure.

3. **Easy Installation** The kit is designed as a top-plug replacement, meaning it can be installed without major disassembly. This makes it a straightforward DIY project for most mechanics.

4. **Cost-Effective Maintenance** Compared to full engine rebuilds or camshaft replacements, this kit is a relatively inexpensive way to maintain engine health. It s a proactive measure rather than a reactive repair.

5. **Compatibility** The 12-0152 kit is specifically designed for the Harley-Davidson Shovel (81-84) engine, ensuring a proper fit and function without modifications.

6. **Reduces Oil Sludge Buildup** By filtering out fine particles, the screen helps keep oil cleaner for longer, reducing sludge formation in the crankcase.

7. **Aftermarket Support** Many Harley-Davidson enthusiasts and mechanics recommend this kit for older Shovels, lending credibility to its effectiveness.

---

1. **Limited Filtering Capacity** While effective for larger debris, the screen may not capture all microscopic particles that can still contribute to wear over time. It s not a complete replacement for regular oil changes.

2. **Potential for Clogging** If the engine is heavily contaminated (e.g., from neglect or poor maintenance), the screen could clog quickly, requiring frequent cleaning or replacement.

3. **Not a Permanent Fix** The screen kit helps mitigate issues but doesn t address underlying design flaws (e.g., oil flow restrictions in the Shovel s crankcase). For severe tappet wear, additional measures (like a camshaft rebuild or oil pump upgrade) may still be needed.

4. **Installation Requires Disassembly** While simpler than a full engine tear-down, removing the top end (cylinder, valves, etc.) is still labor-intensive. Those without mechanical experience may struggle.

5. **Cost of Replacement Parts** If the screen or gasket fails, additional parts (like a new gasket or oil pump seal) may be required, adding to the expense.

6. **Mixed Reviews on Longevity** Some users report that the screen wears out or loses effectiveness over time, especially if not cleaned regularly. Others find it lasts the life of the engine with proper maintenance.

7. **May Not Solve All Noise Issues** If your Shovel has a loud tappet noise, the screen kit helps but may not eliminate it entirely if the tappets are already worn or if there are other issues (e.g., oil pressure problems).

---

The **V-Twin 12-0152 Tappet Oil Screen Kit** is a **highly recommended upgrade** for Harley-Davidson Shovel models (81-84), particularly if you re dealing with tappet wear, engine noise, or a history of poor maintenance. It s a **proactive, low-cost solution** that significantly reduces the risk of catastrophic engine failure by filtering out debris before it reaches critical components.

However, it s **not a magic fix** it works best when combined with **regular oil changes, proper oil quality, and good maintenance practices**. If your engine is already severely worn, additional repairs (like a camshaft rebuild or oil pump upgrade) may still be necessary.

For most Shovel owners, the **benefits outweigh the drawbacks**, making this kit a **worthwhile investment** in the long-term health of your engine.

---

- Excessive tappet noise.

- History of oil sludge or poor maintenance.

- Desire to extend the engine s lifespan without major surgery.

- **Install it as soon as possible** if your bike has high mileage or shows signs of wear.

- High-quality oil (e.g., Harley-Davidson synthetic or a reputable aftermarket brand).

- Regular oil changes (every 500 1,000 miles if the bike is used frequently).

- Periodic inspection of the screen for clogging or wear.

- **Consider additional upgrades** (like a camshaft rebuild or oil pump) if the screen kit alone doesn t resolve persistent noise or performance issues.

Overall, this is a **smart, cost-effective upgrade** for Shovel owners looking to preserve their engine s health.
