CAT 320D экскаваторын хөдөлгүүрийн их засварын бүрэн эд ангиудын хяналтын хуудас
This article provides a comprehensive parts list for overhauling the CAT C6.4 engine used in CAT 320D excavators. It categorizes components by engine system, including pistons, cylinder liners, bearings, head gaskets, valve stem seals and fuel injectors. Each component is described with its replacement purpose and inspection points during a rebuild. The article also compares purchasing options between complete overhaul kits and individual parts, helping repair shops and buyers prepare all necessary components before engine disassembly to avoid downtime waiting for missing parts.
The CAT 320D excavator is powered by the C6.4 engine. During an engine overhaul, wear components and seals must be systematically replaced to restore performance and prevent premature failure.
Overhaul kits bundle most of the above components in one package, offering better convenience and typically better pricing. However, injectors and some seals may need to be confirmed separately.
Before disassembling the engine, confirm the following:
1. Engine nameplate information (model, serial number)
2. Cylinder wear measurements (determines standard or oversized grade)
3. Crankshaft journal wear (determines bearing size)
Send us the nameplate information and measurement data. We will help confirm the required parts list and provide a quotation. An overhaul kit covers most core components and reduces the risk of missing parts.
