Guys,
I want to know how many time you run before checking bearing of your engine??
Do you need to replace it often???
Is it a good thing to change both bearing one time by year???
Thanks ...

Not sure but I can hear mine going in my old YS-80.

There are to many variables to give a specific time to check.
There is no one "right" way to get the best life out of your bearing either.
Wat works great for one person's situation may be bad for someone else.
You will normally hear the bearing going bad and notice a reduction in engine power, before it causes engine damage.

Haaaaaaaaa... ok.... Something wrong with me because It's was too late when I checked my bearing... Cost piston, sleeve, ring, piston lock... Finally, it's cheaper to buy another one than rebuilt it... :(
Do you ckeck that oftenly ???

For the most part, I have always heard my bearings start to go - at idle, it sounds like rocks in a soda can. There was one time though when it didn't make noise, but I could not keep the engine running. It would die repeatedly on a climbout.
I was out of commision for a few months and I did change my bearings as preventative maintenance.

I have two sets of bearing with me at all times, just in case. I also replace the bearings any time the motor makes a weird sound, runs poorly, or starts eating glowplugs.
For me, it only takes 20-30 minutes to swap bearings and redial the fan.

Angelob, afther i thougnt has you said, I remember to have heard a little sound likes you have described.... Finally, i will know now what this sound is it!!! :)
The 100% way to tell if your engine needs new bearings: Look at the crankcase and if it says "OS" anywhere on it, time for new bearings. :mrgreen:
Truthflully though, all the previous has been good advice. Last set I had go was very noisy. Others have eaten glowplugs, or died under load. It really just takes a lot of skepticism and a knack to tell when.
When the time comes, get a good set from one of the notable suppliers, as the ones from teh manufacturer tend to be low to mid grade bearings depending on teh manufacturer.
