Hot-Shot Motorworks has reconditioned 1,000s of Harley Davidson T/C cranks since it was introduced in the T/C engine in 1999. The crankshaft that is used in the XR750 is virtually the same as what is being used in todays T/C engine other than a difference in the stroke and rod length. Crankshaft Balancing - Hot-Shot MotorworksThe most important cause we found was due to the design of the Harley-Davidson crankshaft. It has an enormous amount of Torsional Vibration and Torque Spike.Torque Spike happens each time the air/fuel mixture inside the combustion chamber is ignited. The combustion that results creates a Torque Spike from an extremely rapid rise in cylinder pressure.
Crankshaft Repair, Crankpin Straightening & Heat Treatment. The Metalock Engineering Group provides cost-effective crankshaft repairs involving re-machining, straightening and heat treatment services for all types of large diesel engines, at sea or on land anywhere in the world. Crankshaft systems - EFD InductionCrankshaft induction hardening machines These systems cover every type of crankshaft (marine, compressor, car, truck, etc.) and production volume. Our systems include robot-loaded machines, and drum and single-station models for large crankshafts. We also offer walking beam and chain conveyor machines with a capacity of 1-4 stations.

Therefore, we developed lead-free crankshaft for motorcycle. Until now, crankshaft for motorcycle has been manufactured with lead-added free-cutting steel by a following process; Hot-Forging - Quenching and Tempering (QT) - Prior Machining - Nitrocarburizing - Finishing process because of strength and machinability. heat-treatment after Heat Treatment (Annealing) - QuantiServSuch a pin requires heat treatment if the crankshaft is to be saved. QuantiServ has gained considerable experience with this process and has been able to bring down the hardness on dozens of crankshafts so that they could be saved. Crankpin. Hard spots on a crankpin, until 581 HB in this case. Heat Treatments to Improve the Rolling-Contact Fatigue Mar 03, 2003 · Heat Treatments to Improve the Rolling-Contact Fatigue Life for Crank Pin of Motorcycles. 2003-01-0916. The present work was intended to increase the rolling-contact fatigue life of the crank pin for a motorcycle. The small motorcycle uses a needle roller bearing at the big end of the connecting rod. The needle roller exerts high Hertzian stress on the crank pin.
Sep 30, 2014 · Abstract:Crankshaft as the heart of the piston engine, this paper uses aviation engine crankshaft as the research object, introduces the classification of metal heat treatment process, and analyzes the working conditions, material selection, crankshaft forging temperature and heat treatment process. And as the crankshaft heat treatment quenching cracks, oxidation and decarburization an Heet - Removes Water, Protects Against Extreme Temps Prevent gas-line freeze up by protecting against temperature extremes and corrosion with HEET antifreeze coolant for 2-cycle, 4-cycle and diesel engines. Machining operations for a crankshaft from a 4340 billetAug 04, 2005 · I've got a motorcycle project that may give me an excuse to make a plain-bearing crankshaft. A friend says he can get me 4340 vacuum remelt from his normal supplier anytime I'm ready for it. I'm hoping that someone here is familiar with the machining/heat treatment process. I can picture (in general) how to make the crank.

I checked around, and there are vendors who handle each of these processes, and cost is similar (something like $600 to repair one journal, or about double that to do all the rod journals.
The result is a smoother surface, which leads to improved oil flow, less wear on parts, easier shifting, and a reduction in generated heat. Price:$250. NEW! Atomization Surface Treatment (AST) Our all new, proprietary Atomization Surface Treatment (AST) generates a rougher crank surface to Technology Winberg CrankshaftsEach crankshaft that we build goes through a series of computer controlled furnaces and is transferred from process to process robotically to ensure the highest standard of consistency. All heat treatment processes are monitored by highly trained technicians who check for uniformity throughout the process. Heat-treatment of crankshafts - High Power MediaAug 14, 2009 · Heat-treatment of crankshafts. In the previous article, we looked at the first stages of heat-treatment in the manufacture of crankshafts. Certainly in Formula One, the most popular heat treatment that will be mentioned will be nitriding. Nitriding, as most of you will know, is a surface treatment which, if specified correctly, should have no effect on the bulk of the material, often
