Hi John,

Thanks for your reply.

>>If you just ordered new ones from Losmandy, you should be OK

I did not understand this. I have ordered the OPW that currently comes with new bearings. So I should have ordered other higher quality bearings from Losmandy? The bearings that comes with the OPW are not good enough?

Andre,

Most people who do a mount rebuild usually replace the bearings at the same time. They are inexpensive and therefore disposable. If you just ordered new ones from Losmandy, you should be OK. When inserting into the worm block, use care to press in evenly with pressure or gently tapping on the outside race only. If you press on the inside you can bend them, or if inserted on an angle, they can be warped out of round, and you can create the dreaded 76 second error, where the balls are not riding smoothly between the inner and outer races.

Also the bearing should slide smoothly with finger pressure over the brass worm and should not be forced in or hammered in. One new brass worm I received was very slightly oversized, and I used 400 mesh sandpaper to gently twist and polish the end down until the bearing would fit over.?

Usually I have several new bearings on hand, just in case of any mistake, or possible damage during insertion, or guiding errors that could develop later.

Best Regards,

John
