Tradition of Excellence

Over a half-century ago, the late Lewis Sinor first put a wrench to a Superior® engine. Never did he imagine that this was the start of a tradition that has since grown steadily over three generations and continues to expand today. Lewis’ son, Dale, joined him in 1963 and, today, Dale’s three sons are an integral part of the business. At Sinor, our focus is simple and direct: We are committed to always doing the right thing for our clients, our employees and our industry. Today, the tradition lives on.


Seasoned Expertise

Sinor Engine maximizes the power of new technologies to advance our products and services. Each task, however, requires skilled and knowledgeable people. We are proud of our experienced team of specialists. We are also exceptionally proud of Sinor’s proven, quality-driven reputation which is recognized as one of the very best in virtually every part of the country where Superior® engines are in service.

Used Parts

Over the years, we have accumulated a large inventory of surplus parts for the Superior engine and compressor, including blocks, bedplates, compressor cylinders, and much more. These items can be rebuilt and sold as good, used components at a significant cost savings to the customer. These items are a great alternative to buying new. Next time you are in need of a Superior component but do not want to pay the high prices for a new item, call us and chances are we have a good, used item in our inventory.

Turbocharger Department

Turbocharger work is a large portion of our business so a large part of our facility is devoted to their repair. Units are disassembled and sent to the cleaning department. During disassembly photographs are taken of the entire process and of each individual part. The clearances are also measured and recoreded. The rotor assembly is balanced on the balancing machine inside a clean room. The turbo is then reassembled and all critical clearances and tolerances are recorded. After the unit is shipped, the photographs and clearances are incorporated into a report detailing the findings of the overhaul. This report is sent to the customer. Along with our overhaul abilities, we keep a large selection of rebuilt and good used turbo parts to use in place of damaged parts which reduces the repair costs for the customer.

Cylinder Head Department

This department is the oldest at Sinor Engine. The company got its start repairing cylinder heads. The technicians in this department are the second generation to repair cylinder heads. The heads are disassembled and inspected and pressure tested for cracks. Each cylinder head fire deck is checked for pits and if needed, surfaced in our machine shop. The heads are then rebuilt to manufacturer’s specifications.

Engine & Compressor Assembly Area

Complete engines, compressor, and packages are assembled in the assembly area. This main bay is large enough to simultaneously assembly four units or packages and still have room for accessories and workspace. The area remains uncluttered and clean contributing to the overall quality of the work.

Engine Dynamometer Test Area

We recently added a water brake dynamometer to our test stand which allows us to test run Superior engines at full load. Every shop overhaul we perform is run on the test stand at various loads enabling us to make all necessary adjustments before the engine leaves our shop. Measurements are made and recorded during the test run which are then added to the overhaul report sent to the customer.
