Yamaha Yamalube Yamabond 4 liquid gasket ACC-YAMAB-ON-D4 60min Cure

Description

Product Overview

Yamaha’s Yamalube Yamabond 4 liquid gasket is an original equipment manufacturer (OEM) solution designed to deliver a reliable, high‑performance seal for a wide range of power‑sports applications. Engineered by Yamaha’s dedicated sealing technology team, this product combines a silicone‑based polymer matrix with advanced additives that create a flexible, rubber‑like barrier once cured. The formulation is specifically calibrated to meet the demanding specifications of Threebond 1215, ensuring compatibility with Yamaha’s own service manuals and recommended maintenance procedures.

The gasket material is a silicone‑based liquid that sets in approximately 60 minutes at ambient temperature, forming a resilient seal that can withstand temperatures well above typical operating ranges. Its silicone composition provides excellent resistance to both gear oil and engine oil, preventing degradation that can occur with conventional gasket compounds. The cured gasket remains flexible, allowing it to accommodate thermal expansion and contraction without cracking, which is essential for maintaining a tight seal over the life of the engine.

Physically, the product is supplied in a compact 17 × 8 × 9 inch container weighing only three ounces, making it easy to store and handle in workshop environments. The packaging includes a precise dispensing nozzle that enables accurate application of the liquid, reducing waste and ensuring a uniform layer thickness. The product’s low viscosity allows it to flow into intricate joint geometries, reaching crevices that are difficult to seal with pre‑formed gasket sheets.

Yamabond 4 is intended for use wherever the service manual specifies Threebond 1215, which includes many critical sealing points such as cylinder heads, valve covers, and oil pans on Yamaha motorcycles, ATVs, and other power‑sports engines. By matching the exact performance characteristics of the original specification, it provides a seamless replacement that does not compromise engine integrity or performance. The product’s compatibility with a broad range of Yamaha models has been validated through extensive field testing and laboratory analysis.

Customer feedback reflects a high level of satisfaction, with a 4.8‑star rating based on over a thousand reviews. Users frequently cite the rapid cure time, ease of application, and long‑term durability as key advantages. The product’s best‑seller rank in the automotive category underscores its popularity among both professional mechanics and DIY enthusiasts seeking a dependable sealing solution.

Usage

Yamabond 4 is ideally suited for sealing applications on motorcycles, all‑terrain vehicles, and other power‑sports engines where high temperature and oil exposure are common. Typical use cases include sealing cylinder head joints, valve cover interfaces, and oil pan seams. The product’s silicone base ensures that the seal remains effective even after repeated heating cycles, making it a reliable choice for high‑performance engines that operate under strenuous conditions.

Installation begins with thorough cleaning of the mating surfaces to remove any old gasket material, oil, or debris. Once the surfaces are dry, the liquid gasket is applied using the included nozzle, spreading a thin, even layer across the joint. The parts are then assembled and tightened to the manufacturer’s torque specifications. The gasket begins to cure within minutes, reaching full strength after approximately one hour, at which point the engine can be started and brought to normal operating temperature.

For maintenance, it is recommended to inspect the sealed joints during regular service intervals. If any signs of wear, cracking, or leakage appear, the gasket can be removed and the area re‑cleaned before re‑application of Yamabond 4. Because the product cures quickly, re‑sealing can be performed with minimal downtime, allowing the engine to return to service promptly.

Safety considerations include avoiding direct skin contact with the uncured liquid, as it may cause mild irritation. Users should work in a well‑ventilated area and wear protective gloves. The cured gasket is chemically inert and poses no health hazards. The product is rated for continuous operation at temperatures up to 250 °F (121 °C), providing a wide safety margin for most power‑sports applications.

FAQ

What surfaces can Yamabond 4 be applied to?

Yamabond 4 is suitable for metal surfaces such as aluminum, steel, and cast iron that are commonly found in engine components. The surfaces should be clean, dry, and free of old gasket material before application.

Can I use Yamabond 4 on non‑Yamaha engines?

While the product is optimized for Yamaha specifications, it can be used on other engines that require a silicone‑based gasket with similar performance characteristics. Always verify compatibility with the engine’s service manual.

How long does the cured gasket last under normal operating conditions?

When applied correctly, the cured gasket is designed to last the lifetime of the engine under normal operating conditions, typically many thousands of miles, without degradation from heat or oil exposure.

Is special equipment needed to apply the gasket?

No special tools are required. The included dispensing nozzle allows precise application by hand. For larger joints, a brush or spatula can be used to spread the liquid evenly.

What should I do if the gasket fails or leaks after installation?

If a leak is detected, stop engine operation, clean the affected area, and reapply Yamabond 4 following the recommended preparation steps. The quick cure time enables rapid re‑sealing, minimizing repair downtime.
