Cylinder Head Overhauls - Jenbacher 3 Series

SIDCO offer a complete Cylinder Head Overhaul service for your Jenbacher 3 Series Gas Engines.

Each head is initially inspected for any major damage and measured to ensure it is within dimensional tolerance. Once the customer's cylinder heads have passed initial inspection, they are then fully stripped and 'hot washed' to remove all debris. All components are inspected to ensure they are within tolerance, and suitable for re-fitting. Any not suitable to be re-fitted will be replaced.

Close attention to detail is paid at all times in the process, to ensure that the overhauled heads are suitable to go back into service to provide reliable engine operation.

We take great pride in the quality of our workmanship, and all work is fully warranted. After overhaul, the heads come out looking 'as new' condition ready to give reliable duty.

We may not offer the cheapest overhaul service, but it is of the highest quality, using the highest quality components, which will provide extended service life, improved engine availability and reliability, and lower operating costs.
