Atlas Copco Oil-Free Air Compressor Accessory Gearbox Overhaul Service Kit Model 2906065800

Atlas Copco Core components of the kit

Special disassembly and assembly tools

Including a special puller for the gearbox (used for removing bearing, gear, and other interference-fit components), a set of socket wrenches (matching the specific specifications of the gearbox bolts), a torque wrench (ensuring that fasteners are installed according to standard torque), an internal hex wrench set, a bearing installation guide sleeve, etc.

Some high-end kits also include hydraulic disassembly tools, which can avoid damage to parts caused by hard prying.

Testing and measuring tools

Dial indicators and indicator stands (for measuring the meshing clearance of gears, radial / axial runout of the shaft), feeler gauges (for detecting bearing clearances, gear clearances), level meters (for adjusting the installation level of the gearbox), internal diameter micrometers (for measuring the wear of the bearing seat hole), etc., used to accurately determine the degree of part wear.

Replacement kits for wear-prone parts

Including gearbox-specific seals (such as skeleton oil seals, O-rings, with oil-resistant and high-temperature-resistant materials), bearings (rolling bearings or sliding bearings, matching the original factory model), gear oil (high viscosity index extreme pressure gear oil, suitable for air compressor conditions), fastening bolts (high-strength anti-loosening bolts, some with anti-loosening glue).

Some kits also include gear repair agents (for filling and repairing minor tooth surface wear).

Cleaning and auxiliary tools

High-pressure cleaning guns (for cleaning oil sludge and iron filings inside the gearbox), precision cleaning agents (for removing oil stains on the surface of parts), lint-free wipes (to avoid fiber residue), copper rods (to prevent damage when hitting parts), magnetic rods (to adsorb ferromagnetic impurities), etc.

Protective and consumable materials

Anti-slip gloves, safety goggles, maintenance-specific work clothes, as well as thread lockers, sealants (for sealing the flange surface), bearing lubricating grease (for pre-treatment before installation) and other consumables.

Applicable scenarios and maintenance procedures

Regular major overhaul: Disassemble the gearbox completely according to the operating cycle of the air compressor (usually 10,000 - 20,000 hours) to check for gear wear, bearing clearances, shaft neck accuracy, etc., and complete the replacement and repair of parts using the kit tools.

Fault repair: For problems such as abnormal noise, oil leakage, or abnormal vibration of the gearbox, use the kit tools to quickly locate the fault point (such as poor gear meshing, damaged bearings), and replace the damaged components.

Typical maintenance steps:

Drain oil and disassemble the gearbox, use special tools to remove gears, bearings, etc.;

Measure key dimensions with testing tools to determine if the parts are out of tolerance;

Clean all parts, replace seals, bearings, etc., for wear-prone parts;

Reinstall the components according to standard torque, and ensure assembly accuracy with measuring tools;

Add gear oil, and test-run to check if it is normal.

Advantages of the kit and key points for purchase

Advantages: One-stop supply of tools and accessories, avoiding maintenance interruptions due to incompatible models; Professional tools can reduce the risk of part damage and improve maintenance quality.

Purchase suggestions:

Prioritize the purchase of original factory kits (such as Atlas, Ingersoll Rand, etc.) that match the air compressor brand to ensure compatibility of parts;

If choosing a universal kit, confirm that the tool specifications cover the bolt sizes and bearing models of the gearbox;

Check the material of wear-prone parts (such as seals need to be resistant to gear oil corrosion, bearings need to meet high-speed heavy-load requirements).

Using a professional maintenance service kit to maintain the air compressor gearbox can effectively reduce the probability of transmission system failures, extend the service life of the gearbox, and ensure the stability of the output power of the air compressor.
