586‑3377 CYLINDER LINER is a heavy‑duty engine cylinder liner with 137.185 mm inner diameter, specially designed for CAT 844, 834B and 824H wheel dozers. This cylindrical cast‑iron component is press‑fitted into engine block bores. It provides a smooth wear‑resistant sliding surface for piston and piston‑ring assembly, bears high‑temperature combustion pressure, mechanical friction and cyclic thermal loads, improves heat dissipation performance and protects the engine block from abrasion and corrosion under heavy‑load mining and earth‑moving working conditionsCat® Parts...
Suitable for: Open‑pit mining earth‑moving, highway & railway subgrade construction, large‑scale foundation excavation, stockyard material handling and other heavy‑duty working scenarios for CAT wheel dozers.

Installation Guide
Completely shut down the engine and allow full cooling before disassembly to avoid scald risk.
Remove cylinder head and piston assemblies, take out old liners, thoroughly clean cylinder‑block bores, remove carbon deposits, dirt and burrs.
Inspect new 586‑3377 cylinder liner for cracks, scratches or transport damage before mounting.
Fit new sealing gaskets, press cylinder liner into block bore with proper tooling, ensure installation height meets OEM requirements.
Complete piston‑ring and cylinder‑head assembly, refill qualified coolant and engine oil, perform idle trial run and monitor engine running status.
Maintenance Tips
Keep cooling system well‑maintained; avoid sustained engine overheating which accelerates liner wear and cracking.
Use qualified engine oil and replace filters according to service cycle to reduce abrasive wear on liner inner surface.
Regularly monitor engine oil consumption and blow‑by condition during daily inspection.
When replacing cylinder liner, synchronously renew matched piston rings, seals and gaskets for optimal overhaul result.
