Yup, some Japanese brands also use C3 suffix, while others use different letters. But the brands you mentioned uses C3 suffix.

I checked the replaced bearing ... 6203LU. I'll have to DIY the replacement come the time, with a -C3. Thanks for all the help.

6203 LU, that's NTN designation for 6203-RS1/ QE6, single sided rubber shield. QE6 is standard electronic motor quality, quiet running. :D

Done changing it. Learned another thing too ... i need to loosen the nut holding the pulley before i could adjust the tension bolt. Btw, the replacement bearing used by the case was also a -C3 ... not bad, it lasted 3 years.

Thanks again guys!

pahabol pala ... When you have alreaby inserted the bearing in the pulley, which side faces the engine block? the side where the bearing was inserted of the other side?

What do you mean which side?

Open side bearing should always be placed inside, while the covered side is on exterior to protect from dust ang other particles.
