Continental Aircraft Engine Cylinders

Repair & overhaul capabilities for all of your cylinder needs

Our aircraft engine cylinder shop offers our customers repair and overhaul capabilities for their cylinder needs. Our state-of-the-art honing and boring machine precision grinds the aircraft cylinder barrel to exacting standards and trueness while automatically holding the required tapered choke for the cylinder. Seats are precision ground and valves are lapped into place. Pneumatic and liquid testing is accomplished for assurance of optimum seating. Special attention is given to proper spring tensions and heights to maximize the performance of the cylinder. The piston rings are sized to fit the barrel and installed providing the customer a trouble-free installation.

If you are not overhauling the engine, a repaired cylinder is a very cost effective solution. At overhaul we have to change certain parts, regardless of time or condition. We can fully repair your cylinders and will change any item that does not meet the overhaul service limits specification criteria. We will perform Non-Destructive Testing for cracks, cut valves and seats and lap, install and leak check the valves. New rings will be fitted to the piston and installed in the newly honed barrel. The cylinder will be painted and a new gasket set will be provided. Each cylinder will include the valves installed, piston & piston rings installed and a new gasket set.
