SKF bearings in the middle of use, bearings, connecting rods and is very susceptible to damage. But a lot of people don't know what's going on should be actions that will do no harm to them. And how they can be used longer even infinite life.
　　So, connecting rod bearings in SKF and when there is a problem and have a good look. How do we prevent problems?
　　L) connecting rod big end bearing noise when engine running, sometimes issuing heavy, da, and da "sound, which will diminish or disappear when the sound running at idle speed, when the burst of power, sounds and vibrations are significantly increased.
　　This is because excessive wear or connecting rod big end bearings and bearing hole Assembly clearance is too large, when the bearing spins more due to radial impact arises when a heavy sound. This sound is found, shall be immediately stopped shooting, preventing the deterioration of failure causing parts of damage. Until the engine scrapped.
　　When checked, first remove the cylinder, push rod or sway rod up and down, when the amount of swing hours connecting rod may continue to be used along a vertical connecting rod felt there was a marked amount of shake (that is, connecting rod small end hole of the radial clearance), and measured amount of swing at the head is greater than 1, shows wear serious, in which case the link should be replaced.
　　2) bearings knocking when spinning, SKF bearings and bearing bore is also relative movement, the engine produces some clutter "slightly low whistle, and the towering" sound.
　　Idle running sound obvious, is particularly acute when accelerating. Sound similar to the connecting rod big end bearing rings, however former is messy, irregular, which only ended in the upper and lower points, there are certain rules. This sound occurs because, mainly due to wear and tear caused by long-term use or poor lubrication SKF bearings.
　　In addition, it may also be due to improper disassembly and Assembly or disassembly and Assembly method more than once, causing housing bore diameter increases, bearing and bore clearance is too large. This sound is found. Timely replacement of bearings, improving the bearing lubrication, or re-buildings bearing block hole of mounting holes, or replace the box.
