Why Use Thunderbolt
1. We have been in business longer than anyone else has that you will find on the Internet. Our company has been remanufacturing engines and transmissions for over 70 years.
2. We are not a re-seller. Many companies buy cheap inferior engines and mark them up 50% or better and sell them to you. If you have a question or problem, you are sent back to whom they bought the engine from, instead of dealing with the company directly. We sell our products directly to you and not through some middleman or a third party web site.
3. Our machinery is all new and state of the art. None of our equipment is over 5 years old. As newer equipment becomes available, we are steadily replacing any outdated machinery with newer, more sophisticated equipment.
4. The company president, Harry Hartley II, sits on the board of directors of Production Engine Rebuilders Association, which only an elite, few remanufacturers may belong to. Mr. Hartley is in the machine shop everyday, personally assisting the remanufacturing process to further ensure that you are receiving a high-quality remanufactured engine or transmission.
5. Our prices are extremely reasonable. Because we are not distributing through a middleman, we are able to get you factory direct pricing. We do all the same procedures as many remanufacturers and sell our engines and transmissions for half the price of other remanufactured organizations.
6. THOROUGH CLEANING
Every engine is completely disassembled. Blocks, heads, connecting rods, crankshafts, and camshafts for domestic engines are thoroughly cleaned in the Bayco Bake Oven and shot blasting equipment engines are completely cleaned through.
7. CRANKSHAFTS
Crankshafts are precision machined to exact tolerances with no odd size bearings or journals. Thrust surfaces (domestic engines) are machined in a two-step process to provide precise surface finishes for smooth engine operation and reduced thrust bearing wear. Every journal is inspected and measured with critical accuracy. After machining, oil holes are chamfered to improve lubrication and every journal polished to a smooth finish for long bearing life. Crankshafts are thoroughly cleaned with special emphasis to flushing and brushing out oil passages to remove any contaminants.
8. CAMSHAFTS
Camshafts are inspected for wear, dimensional accuracy, and gauged for straightness. Camshaft lobes are carefully machined to correct specifications. Each shaft is Parco-Lubricated to improve lubricant adhesion, especially during break-in. Any camshaft not meeting THUNDERBOLT's exact specifications is replaced.
9. CYLINDERS
Cylinders are bored and diamond honed to exact specifications. Cylinder finish and size are closely monitored to industry surface finish standards as well as for accuracy and consistency through Statistical Process Control. This assures smooth piston travel and engine performance. THUNDERBOLT guarantees no odd size cylinders. The block to head mating surface is closely inspected and resurfaced as required to provide the correct surface finish for today's gasket materials.
10. CONNECTING RODS
Connecting rods are machined and gauged to within a half a thousandth for improved operation, especially in today's engines. Rods are carefully machined to avoid taper and to the standard diameter of original equipment. All rods are checked for bend and twist to assure smooth operation.
11. HEADS
Heads are carefully inspected for cracks and flaws through procedures such as magnetic particle inspection and pressure testing. Every head is resurfaced to exact dimensional tolerances and the surface finish is carefully monitored for proper sealing with the block. Valve seats and guides are machined to exact specifications or replaced to assure correct valve alignment and seating and optimum engine performance.
12. ASSEMBLY
Every engine is precisely assembled by THUNDERBOLT builders. Attention to such details as a final wash of new and machined parts and prelubricated camshafts, pistons, and crankshaft journals assures a clean, smooth running engine that performs to your expectations.
13. TESTING
THUNDERBOLT live tests every popular Complete domestic engine with recorded inspections of temperatures, oil pressure, vacuum pressure, and compression. Import engines are tested for correct oil pressure, compression, torque to turn and proper oil pump operation. THUNDERBOLT's testing is one of the many ways we assure your satisfaction.
14. STATISTICAL PROCESS CONTROL
Processes are continually monitored through Statistical Process Control to assure accurate machining, smooth engine performance and complete customer satisfaction.
