6240-61-2560 Original Komatsu Heat Exchanger Gasket--Drilling Machine Spare Parts

Hello, Equipment Owners and Maintenance Chiefs! I am the supplier who specializes in solving problems like "oil cooler leaks," "radiator seepage," "heat exchanger joint failures," and "engine oil emulsification." Today, I’m recommending a "perforated sealing sheet that looks simple but acts as the 'safety barrier' maintaining order in oil-water heat exchange and preventing fluid crossover"—the Professional Heat Exchanger Gasket for Construction Machinery (Part No.: 6240-61-2560).

Anyone in mining or infrastructure knows that oil coolers and hydraulic radiators on excavators and loaders operate in a "world of extremes"—caught between high-temperature oil or hydraulic fluid (often exceeding 100°C) and high-pressure coolant. These two media must exchange heat through the exchanger but must never mix. Many cheap gaskets on the market look like rings but are merely cut from asbestos sheets or punched from recycled rubber mats. Under constant thermal cycling and pressure fluctuations, they carbonize, turn brittle, and lose elasticity within days. Once the gasket fails, minor issues involve oil contaminating coolant leading to bearing failure; major failures involve coolant leaking into the hydraulic system, causing fluid degradation and total system shutdown. Our Heat Exchanger Gasket is specifically engineered for oil coolers and heat exchangers on heavy-duty equipment like Komatsu excavators and loaders. It doesn’t just fill space; it withstands extreme heat, resists oil attack, recovers from compression, and seals tight. Choose us to install a "high-recovery sealing shield"—ensuring coolant circulates freely and hydraulic oil cools efficiently, keeping your equipment’s heat exchange smooth and stable in harsh, vibrating, high-temperature conditions.

Why You Must Use Our "Hardcore" Heat Exchanger Gasket

• Non-Asbestos Oil-Resistant Material: Safe & Eco-Friendly:

  The sealing material dictates service life and safety, especially at oil-water interfaces.

• Material: Constructed from high-quality non-asbestos, oil-resistant sealing sheet. It contains absolutely no asbestos fibers, eliminating the health risks associated with asbestos dust and meeting modern environmental safety standards. The sheet is a homogeneous composite of aramid fibers, oil-resistant rubber, and functional fillers, featuring a dense, uniform internal structure.

• Performance: Offers exceptional oil resistance and fluid compatibility. It is highly "immune" to mineral hydraulic oils, gear oils, engine oils, and glycol-based coolants. During long-term immersion, it resists swelling, shrinkage, delamination, or media contamination. Compared to traditional asbestos gaskets, its sealing reliability is vastly superior, solving the industry-wide pain point of oil-water crossover.

• Precision Stamped: Exact Dimensions:

  Heat exchangers demand high surface flatness and dimensional accuracy; process dictates success.

• Process: Manufactured via precision stamping in a single operation. The position and diameter of all oil ports, water ports, and bolt holes are tightly controlled with minimal tolerance.

• Advantage: Unlike hand-cut or crudely molded gaskets, our product features clean edges, no burrs, and accurate bore alignment. It requires no trimming during installation and achieves perfect surface contact with the exchanger core and housing. This eliminates localized sealing failures or media crossover caused by dimensional deviations, meeting the stringent sealing requirements of high-pressure exchangers.

• Superior Compressibility & Recovery: Anti-Vibration & Tight:

  Exchangers are mounted near engines or radiators, subjecting them to violent vibration; recovery is vital.

• Property: Exhibits excellent compressibility and recovery. When you torque the bolts to spec, it deforms optimally to fill microscopic irregularities on the flange faces. When equipment vibrates or temperatures shift, its resilience automatically compensates for fluctuations in bolt preload and minor flange movements, maintaining constant sealing pressure.

• Value: In the high-vibration, high-temperature swing environments of mining, it resists vibration relaxation and prevents bolt loosening, stopping "weepage" and drastically extending service intervals.

• Heat & Aging Resistant: Extended Service Life:

  Oil coolers and hydraulic radiators run extremely hot; heat resistance is fundamental.

• Durability: Offers exceptional high-temperature resistance and anti-aging properties. Near hot oil coolers , it won’t become tacky, char, or crack. Under long-term immersion in hot oil and coolant, it won’t soften or degrade. It also resists chemical attack from coolant additives, ensuring stable long-term performance.

• Result: A quality heat exchanger gasket often lasts 2–3 times longer than a standard asbestos gasket, surviving multiple overhaul cycles and significantly lowering operating costs.

Core Product Parameters

Typical Application Scenarios

• Oil Cooler Sealing: Located between the engine block and oil cooler to prevent high-temperature oil leaks and stop coolant intrusion into oil galleries.

• Hydraulic Oil Radiator Sealing: Located at the interface between the radiator core and inlet/outlet fittings to withstand hydraulic pressure spikes and prevent oil loss.

• Intercooler Sealing: Located between the intercooler core and intake piping to prevent pressurized hot air leaks, ensuring charge air efficiency.

• Equipment Overhaul: Replacing old gaskets exhibiting hardening, swelling, leaks, or burnout to eliminate oil-water mixing risks and restore exchanger efficiency.

The Distributor's Promise

1. Exact Match: Just provide Part Number 6240-61-2560 or your equipment model (e.g., PC300, WA470), and we ship immediately. No need to measure inner/outer diameters—hassle-free.

2. Rugged, Leak-Free: We guarantee our gaskets use genuine non-asbestos, oil-resistant material with superior recovery. After installation, they will not seep or leak, regardless of vibration or heat. If leaks develop within days, we replace it.

3. Value for Money: We don't sell the cheapest asbestos or recycled rubber gaskets, which seem affordable but fail quickly—risking thousands in downtime or damage from a single leak. We sell the most durable. Do the math: one quality gasket ensures the safety of your engine and hydraulic system—an unbeatable investment.

A Quick Tip for the Mechanics:

Brothers, installing this gasket requires cleanliness and precision.

1. Clean Thoroughly. This is the most critical step! Before installation, clean the exchanger core and housing surfaces until they are spotless and reflective. Remove all old gasket material, carbon deposits, oil, and rust using scrapers, wire brushes, sandpaper, and solvent. If the surface isn't clean and flat, even the best gasket will leak.

2. Inspect Surfaces. Check sealing surfaces for warping, cracks, or deep corrosion pits. If warped, you may need to use sealant or resurface the flange. Check bolts and nuts for damaged threads.

3. Install Correctly.

• Positioning: Place the gasket squarely between the core and housing, aligning all bolt holes and fluid passages. Ensure it isn't folded or twisted.

• Lubricate: Apply a dab of oil or high-temp anti-seize to bolt threads and nut faces to reduce friction and ensure accurate torque readings.

• Tighten Diagonally: Using a torque wrench, tighten in a crisscross pattern from the center outward in 2–3 progressive stages . Strictly adhere to the manufacturer’s torque specs! Under-tightening leaks; over-tightening warps housings or snaps bolts.

4. Test & Inspect. After installation, fill with the appropriate media. Start the equipment and bring it to operating temperature. Carefully inspect the gasket perimeter for leaks. Check the dipstick and coolant reservoir for signs of crossover. Confirm all is well before returning the machine to service. Work safely and go home in one piece!
