Komatsu 4D95 Engine

Engine handles sand, dust, and heat without problem. Simple setup — fuel lines, mounts, exhaust all matched. It's been in use 6 days a week on excavation — still like new.

Works great in Komatsu D31. Zero smoke, stable idle, good fuel pressure. Mechanics confirmed everything is OEM spec. Great for rural jobs — reliable and easy to maintain.

Got this engine for a backhoe conversion project. It's a great performer — good torque, clean exhaust, and no electronics. This is how diesel engines should be. Very happy with it.

Works in an old Komatsu forklift. Very smooth engine, low vibrations, and easy to install. Engine came sealed and dry, looked completely new. Starts fast even after standing for days.

Installed in a Komatsu PC120-3. Factory engine, mechanical fuel pump. Started first try, holds oil, turbo is dry. After 90 hours — no issues. Very satisfied.
