Polaris snowmobile crankshaft exchange


A good core is simply one that can be re-conditioned to MCB standards. We prefer the connecting rods also be usable but depending on the application we use new connecting rods anyway so that may not automatically disqualify the crankshaft.

If the crankshaft is broken at a cross pin the crank may still be a good core because all pins are replaced when rebuilt anyway. The center gears are also typically replaced with new when available so that also does not always denote a bad core.

Crankshafts for Polaris

Cylinders must NOT be ported we can simply re-plate your cylinders if this is the case. Cylinders must not be "sleeved" where they were not originally. Also core refunds will be reduced for the following: Stripped threads, broken skirts, and sealing surface damage and dings. We expect the bores to have damage and scoring and that is perfectly acceptable however if there are large cracks or transfer port cracks that cannot be accessed for welding the core is not usable.

Cylinders that have been re-plated poorly or plated more that times will generally fail in the process so keep that in mind. This is often where additional damage occurs and can lead to losing your refund. A crankshaft is very hard to damage but a cylinder is EASY to damage.

You MUST protect the cylinders' external surfaces head surface, base, skirts, etc when shipping the core back. We recommend wrapping the cylinder s in cardboard first and then putting the cylinder in a box thereby protecting it from drop page and other cores banging together as it travels. We normally include TWO copies of you invoice when we send you your new parts with a note saying to send the 2nd copy back with your cores.

Also if you are sending your cores from a location that has their business name on the label please have then add your name to the label if possible.

Chrome will fully restore your motorcycle cylinder, snowmobile cylinder, PWC cylinder, or any factory hard chrome or Nikasil plated cylinders. By focusing on exceptional quality, fast turnaround time and personalized customer service, we have now plated well over 1 million cylinder bores for a variety of applications and brands, including but not limited to:. Cylinder distortions - resulting from standard operational loads, temperature variations and assembly inconsistencies - create a loose piston fit.

Piston engineers purposely size down to ensure the piston will reasonably accommodate these inconsistencies, preventing scuffing or engine lock. But this improper fit means lost output. The perfect seal minimizes secondary motion and allows optimal compression and output. Oil Load is spread out to a much wider contact point, reducing friction and eliminating piston slap and rocking. Our piston coating services are safe for all engines, will delay failures and reduce vibration in two-stroke, four-stroke and vintage motors of all types.

Cylinders repair that are out of spec are overbored, fitted with a cast iron sleeve and machined for port match and honed for final fit to the new pistion and ring assembly. Crankshaft stubs must be clean and undamaged at seal-mating surfaces and bearing-mating surfaces. Tapers must be clean, and keywaysand threads sound. The main bearing on a crank often outlasts other engine bearings and bushings, making it possible to keep old cranks in service a long time, and often allowing them to remain un-rebuilt during an engine overhaul.

That's fine if the big end bearing shows no play and axial play on the connecting rod is within tolerance. The trouble comes when the crank is removed and reinstalled, which in vertically split engines generally requires some method of force to pull the crankshafts into their supporting bearings.

Unless this is meticulously performed, it is very easy to throw the crank halves out of alignment, causing the crank shafts to run eccentrically, which stresses the supporting bearings and introduces engine vibration.

Any time a crank is removed, it should be tested for trueness before reinstalling with a special vblock jig and dial indicators. Services Overview. Winterizing Services. Shrink Wrapping.
