    Problems With Tight Connecting Rod Bearings | It Still Runs

    Any very light oil will work, including sewing machine oil. For more information on oiling your bearing see Should I bearngs my yo-yo? Using an unlubricated bearing will cause it to wear out and its condition will deteriorate. Could the bearing be faulty?

    Tight or stiff bearing problems can be the result of many factors that lead to their malfunction. Rod bearings can spin, freeze, stretch, deform and suffer out-of-round conditions. Rod bearings have precision, machined surfaces that must handled in a contamination-free . Apr 17,  · My aluminum tri-spinner (ideass.co) just wouldn't spin for more than a few seconds. There was clearly a rub that was stopping the bearing from. Sep 19,  · If the bearing is dirty it will feel rough, not spin for long, and may be noisy. In most cases performance can be greatly improved by cleaning the bearing. For information on cleaning a bearing see our yoyo help section How to clean your Yo-Yo ideass.co is good practice to clean a bearing if the performance deteriorates.

    Yes it is possible, but rare. There is actually very little that can break in a good quality bearing. In my experience most ball bearing problems result from dirt getting into the bearing. When inner rod bearings have slin clearance between the bearing surface and the crankshaft journal, a proper oil film has no room to reach between the two surfaces.

    This increased friction produces heat, causing the bearing to expand in the race, further cutting off the oil delivery. When temperatures reach as high as degrees, it leads to annealing or galling of the bearing to the journal race. This will often tighten or freeze the bearing against the crankshaft journal.

    Blueish-black marks appear on bearings and journals that have suffered extreme overheating. An overly tight bearing can be the result of an out-of-sequence torque procedure, or a torque pressure that exceeds the manufacturer's specifications.

    The sspin surface will crush against the journal, causing excessive friction and heat. Over-torqued or over-tightened bearings cause the rod end cap to bow in the center, resulting in an out-of-round profile.

    The center gap in the bearing will chafe and vibrate with each revolution, degrading the bearing material and removing minute metal particles. This causes vibration and rod knock that baerings progressively worse. Tight or crushed bearings can deform the oiler hole alignment between the crankshaft journal and the bearing oiler hole, causing a reduced flow of oil to the bearing surface inside the connecting rod journal.

    Without proper lubrication to keep the bearing from contacting the journal, temperatures rise and bearing material becomes scuffed.

    Repeated scuffing leads to excessive clearance and rod knock. Excessive rod knock can throw the rod as a result of the major imbalance in the connecting rod rotation. Tight bearings cause excessive connecting rod bolt stretch. Bolt stretch causes the threads to weaken and tear the threads inside the rod cap.

    Bolts under such stress fatigue prematurely and lose their tensile strength; they cannot be reused and expected to indicate proper torque numbers. Bolt stretch gauges have to be used to measure the length of bolts when they have been fully loaded and torqued to specifications.

      A customer emailed me to say he had a faulty yo-yo bearing. The bearing had been working ok but after a time became slow and would not spin very well: his bearing had broken!
