Doosan D2366 Engine Cylinder Liner 65.01201-0019

Doosan D2366 Cylinder Liner 65.01201-0019

The 65.01201-0019 cylinder liner is supplied for Doosan and Daewoo D2366 / D2366T diesel engine repair. It is used during engine overhaul when the original cylinder bore is worn, scratched, damaged or no longer suitable for stable piston ring sealing performance.

This page is focused on the D2366 engine cylinder liner application. It should not share the old generic cylinder liner table with Komatsu, Cummins, Caterpillar or Mitsubishi engine parts, because those unrelated part numbers weaken the D2366 and 65.01201-0019 product signal.

Part Number and Engine Application

The main part number for this page is 65.01201-0019. It is used as a cylinder liner reference for Doosan / Daewoo D2366 and D2366T diesel engine applications. This page does not use a separate Ref Cross field because any additional number should still be confirmed by old sample, engine model and liner dimensions before shipment.

Engine Model: Doosan / Daewoo D2366 / D2366T

Additional Number and Fitment Check

Some aftermarket references list 65.01201-0051 together with 65.01201-0019 for D2366 / D2366T applications. This page keeps 65.01201-0019 as the main product signal. If a buyer provides 65.01201-0051, the number should be checked together with the removed liner sample, engine plate and liner dimensions before quotation.

Main Part Number: 65.01201-0019

Additional Check Number: 65.01201-0051

Difference from the D1146 Cylinder Liner Page

This product should not be treated as the same page as the Doosan D1146 cylinder liner. The D1146 page targets 65.01201-0020 / 65.01201-0050, while this page targets 65.01201-0019 for the Doosan D2366 / D2366T engine application.

Keeping both pages is acceptable because they serve different Doosan engine series, different part number searches and different repair requirements. To avoid duplicate content, this page uses D2366 wording, 65.01201-0019 part number signals and separate confirmation notes.

Key Checking Points Before Order

Cylinder liners should not be confirmed only by the excavator model. For accurate matching, please check the old part number, engine model, removed liner dimensions and cylinder block condition before shipment.

Engine Check: Confirm whether the engine is D2366 or D2366T.

Part Number Check: Confirm 65.01201-0019 from the old record, supplier record or removed sample.

Old Sample Check: Provide clear photos of the removed cylinder liner from multiple angles.

Dimension Check: Confirm inner diameter, outer diameter, total height and flange size.

Repair Check: Check the piston, piston rings and cylinder block condition together before rebuilding the engine.

Cylinder Liner Replacement Notes

When replacing the 65.01201-0019 cylinder liner, the piston, piston rings, cylinder block condition and engine overhaul requirements should be checked together. If the liner is supplied as a semi-finished type, machining may be required before final installation.

For D2366 / D2366T engine repair, the liner should be selected together with the piston and ring condition. If the old liner has abnormal wear, scoring, overheating marks or poor sealing traces, the related piston and ring set should also be inspected before rebuilding the engine.
