The JASPER Engine 3 YEAR/100,000 mile warranty

JASPER Engines & Transmissions can offer this beefy warranty on our remanufactured gas engines because every one of them goes through our extensive "Do It Right" process that ensures worry-free operation and a high quality product that we are proud to offer here to our local drivers.  Why do we choose JASPER?  

Thorough Cleaning:  Every JASPER reman gas engine is completely disassembled. Blocks, heads, connecting rods, crankshafts and camshafts are thoroughly cleaned through a variety of processes to remove contaminants that can result in premature wear to internal engine components and early engine failure. 

Crankshafts:   These are precision machined to exact tolerances with no odd size bearings or journals. Thrust surfaces (domestic engines) are micro-polished 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.

Camshafts:  These 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 JASPER Engines' exact specifications is replaced.

Cylinders:   All are bored and honed to exact specifications. Most gas engines are torque plate honed - a process we learned from our involvement in NASCAR - that eliminates cylinder distortion after the head is bolted and torqued to the block. This process eliminates a major cause of engine blow-by. Blocks are carefully inspected for cracks and flaws through procedures such as magnetic particle inspection. Cylinder finish and size are closely monitored to industry surface finish standards as well as for accuracy and consistency. This assures smooth piston travel and engine performance. JASPER 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.

Connecting rods:  All 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.

Heads:  All are carefully inspected for cracks and flaws through procedures such as magnetic particle inspection. 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.

Assembly:  Every JASPER gas engine is precisely assembled by trained JASPER builders. Attention to such details as a final wash of new and machined parts and pre-lubricated camshafts, pistons, and crankshaft journals assures a clean, smooth running engine that performs to your expectations.

Testing:  JASPER Engines live tests every popular Complete domestic and import reman engine with recorded inspections of temperatures, oil pressure, vacuum and compression. Engines are black-light inspected to assure there are no oil leaks. JASPER's testing is one of the many ways we assure your satisfaction.

Quality Control:  Consistent quality is maintained through a continuous training program of technicians, many of whom are ASE certified, backed with statistical process control. Technicians are also JASPER Engine Certified to specific engines and job functions. Quality audits of all areas of the engine are scrutinized for cleanliness, surface finish quality, lubrication, clearance and wear patterns.

JASPER WARRANTY:  Install JASPER Engine products with confidence. Every JASPER remanufactured engine is backed by a nationwide warranty.  Complete engines for passenger cars and light duty trucks receive a 3 year/100,000 mile (whichever occurs first) parts and labor warranty. (Ambulance, off-highway vehicles, package delivery, police, snow removal, taxi, tow truck, or any vehicle over 1 ton, 18 months or 100,000 miles, whichever occurs first.) A technical hotline (1-800-827-7455) and 24 hour 7 day emergency warranty information are also available.
