🔧 Original WEICHAI WD12G420E211 Diesel Engine for SDLG 86H – Powerful & Reliable 🚜

Our 86H is used in road construction. Engine came in factory spec, everything matched. Went straight to work. Oil pressure normal, no smoke, doesn't burn oil. Great engine.

Measured all vitals after install — compression perfect, no injector leaks. Cooling system works well under pressure. After 60+ hours, still zero oil loss. Best choice if you want real OEM.

Good engine. Real Weichai, not rebuilt. Loader back to work same day. Very strong under load. No issues so far.

Installed in SDLG loader used for aggregate transport. Engine feels brand new — perfect torque at low RPMs. Our operators like the smooth throttle and quiet idle. Fast delivery and proper invoice included.

Bought for a mining loader (SDLG 86H). Heavy-duty crate, clean motor. First startup went great. Handles extreme conditions — dust, long hours, and variable load. Weichai quality is always top tier.
