Volvo T5 Closed Decking Service

For Volvo T5 Engine Blocks

Our closed decking services for Volvo T5 (such as B5234T and similar) engines address the prevalent issue of cylinder liner cracking in the gaps between cylinders. By implementing a closed deck, we provide robust support for the cylinder outer walls. Precise steel shims, cut to exact gap forms, fill these spaces, eliminating cylinder flex in this critical area.

What is Closed Decking?

Closed decking involves machining the top plane of the engine case (the head plane) to accommodate CNC-machined inserts. This process ensures that the cylinder walls are fully supported, particularly at the top where combustion occurs and where the support is most crucial.

Benefits of Our Closed Decking Service:

• Eliminates Cylinder Liner Cracking: Supports and strengthens the cylinder outer walls, preventing cracking in the gaps between cylinders.
• Reduces Cylinder Flex: Fills gaps with precise steel shims, ensuring no flex in the cylinder walls.
• Enhances Engine Reliability: By stabilizing the cylinder walls, the engine becomes more reliable under high-pressure conditions.

Our Process:

1. Machining the Engine Case:
   • The top plane of the engine case is precisely machined to accept the CNC-machined inserts.
2. Inserting Steel Shims:
   • Steel shims are cut to exact specifications to fill gaps and provide additional support.

Additional Services:

We offer comprehensive services, including pickup and re-delivery of your engine case. Once all chosen engineering processes are completed, your engine case will be ready for assembly. You can either proceed with the assembly yourself or entrust it to our professional engine builders.
