CUMMINS ISM ENGINE REPLACEMENT OPTIONS
When it comes to the wellbeing of your engine there could be an excess of issues and mishaps - worst case scenario, you could be left with an issue where you are cornered into replacing your engine. However, some circumstances may just require you to replace some parts or components, or maybe your engine just needs a mere refreshment. Of course, cost, time, and availability will play a part in your decision making, so let us inform you of the pro’s and con’s of a new Cummins ISM engine from the dealer.
A remanufactured Cummins ISM long engine block is a great replacement for someone who has been the victim of a catastrophic internal engine failure, but luckily escaped with good re-useable external components that can be salvaged from their old motor. Long blocks are also a good alternative when trying to reduce costs in when faced with such an issue.
Our team of machinists and engine builders come to do a full core tear down, cleaning, inspection, and machining of the engine before it leaves our facility to ensure perfection each and every time.
However, it is crucial to note that all of our Cummins ISM remanufactured long blocks are constructed with a combination of both reman and new parts. However, we do not recondition or refurbish former engine parts but rather completely rebuild the old ISM motor to OEM specs.
Every Cummins M11/ISM motor is initially stripped. Blocks, heads, rods, crankshafts and camshafts are thoroughly cleaned in a chemical jet wash or hot tank to get rid of any impurities that could hasten both early component and engine failure.
Prior to being thoroughly inspected by our quality control department, crankshafts are precision machined to exact tolerances, polished & magnafluxed.
Heads are resurfaced to ensure a proper sealing surface with the block and a finish consistent with today's new gasket materials. Valve height is mic-d and every head is vacuum tested to assure an accurate valve seating.
Blocks naturally pick up imperfections, therefore, we use magnetic particle which carefully inspects for cracks and defects. Cylinders are then bored, honed and inspected to precise tolerances. Torque plate honing is performed on some engines to prevent the chances of cylinder head distortion after the head is bolted and torqued to the block. This process stops a major cause of engine blow-by. Block surfaces are machined and then inspected to ensure proper finish.
Camshafts are carefully inspected and precisely machined to provide correct lift. Lobs are measured with a micrometer to make sure OEM tolerances are met.
Connecting rods are cleaned, then machined to O.E.M. specifications and honed to the standard diameter of original equipment for even distribution of stress on the bearings. New bushings are fitted and machined in all bushed rods. Every rod is carefully inspected for bend and twist.
Our Cummins M11/ISM long block engines receive a standard set of new parts such as pistons and rings, bearings, gaskets and seals, and liners. These new parts guarantee excellent performance and consistency throughout the lifetime of the ISM. The new parts are a combination of both OEM and Aftermarket parts when available.
