Description
The D24 rebuild kit is a complete minor engine rebuild solution designed specifically for the Doosan D24 2.4L diesel engine. This kit provides all essential internal components required to restore engine compression, oil control, and overall reliability during a standard rebuild or in-frame service.
The D24 rebuild kit is commonly used in Doosan-powered equipment and Bobcat machines utilizing the D24 engine platform. It is ideal for addressing wear-related issues such as low compression, bearing wear, and gasket failure without requiring a full overhaul with liners or crankshaft replacement.
This kit includes new standard-size pistons (90.00 mm), bearings, and complete gasket coverage for both upper and lower engine assemblies. Precision-machined bushings and thrust components are also supplied to ensure proper alignment and long-term durability under demanding operating conditions.
Key Features:
- Complete minor rebuild kit for Doosan D24 engines
- Includes upper and lower gasket sets for full sealing coverage
- Ideal for in-frame rebuilds.
Application:
The D24 engine used in:
- Doosan compact excavators
- Bobcat skid steers & track loaders
- Toolcat utility machines
