FAQ

Q1: Is this a direct replacement for the original Komatsu cylinder liner?
A1: Yes. This aftermarket cylinder liner kit is manufactured to the exact OEM specifications of part numbers 6136-21-2210 and 6136-31-2030. It is designed as a direct, bolt-in replacement, requiring no modifications for proper installation in a Komatsu 4D105-5 engine.

Q2: Does the kit include all necessary seals or gaskets?
A2: This listing is specifically for the cylinder liner kit. It typically includes the liners themselves. Critical sealing components like O-rings or head gaskets are usually sold separately for a complete overhaul. Please confirm the exact kit contents with our sales team or check the product images/details to plan your parts order accordingly.

Q3: What are the signs that my Komatsu excavator needs cylinder liner replacement?
A3: Common indicators include excessive blue/white exhaust smoke (oil burning), loss of engine power and compression, increased oil consumption, coolant contamination (milky oil), or audible knocking from the engine block. A compression test or leak-down test can confirm liner or ring wear. Regular maintenance and proper coolant filtration are key to extending liner life.
