TREGO 52-830 – Counterbore Cutting Tool Kit for Cylinder Liner Seat in Scania Engines
The TREGO 52-830 SCANIA ENGINE KIT is a professional tool set for in-place machining of the upper cylinder liner seat in Scania wet sleeve engines, ideal for precise operations without removing the engine block.
DESCRIPTION
The TREGO 52-830 – SCANIA ENGINES CUTTING TOOL is a precision-engineered counterbore cutting kit developed specifically for reconditioning the upper cylinder liner seat in Scania wet sleeve engines.
Designed through a direct collaboration between Trego and Scania, this tool represents a specialized solution for machining operations where standard oversized liners fail to guarantee effective coolant sealing. It is also applicable in cases where cracks are present in the upper counterbore area of the cylinder block.
This tool is compatible with Scania D9, D11, D12, D13, and D16 engine series, all of which utilize standing wet-type cylinder sleeves. The main advantage of the TREGO 52-830 system lies in its ability to perform precise in-situ machining directly on the engine block, without requiring engine removal from the chassis. This greatly reduces service time and allows for targeted, professional intervention in the field or workshop.
The complete kit is supplied in two cases, containing the main milling body along with dedicated tool holders equipped with high-precision cutting inserts for both the liner guide and counterbore ring. A setting gauge is included to ensure accurate tool positioning, and protective covers are provided to shield the engine block from machining chips during the operation. Allen wrenches, spare inserts, and cover plates complete the equipment, making the tool immediately ready for use.
For increased control and smoother cutting action, the system can be optionally paired with a pneumatic drive unit, specifically the Mira VGX or Mira BB models. In combination with the dedicated counterhold system, this configuration helps maintain consistent rotational stability, reducing vibration and operator fatigue while improving machining results.
The TREGO 52-830 SCANIA ENGINE KIT is official equipment approved by Scania and a valuable asset for any engine rebuilding specialist dealing with cylinder liner seat damage on Scania engines. Its robust construction, integrated centering system, and precise cutting performance make it a highly effective tool for restoring the correct geometry and sealing surface required for proper wet liner installation and long-term engine durability.
