There are 2 reasons why you would blow out the bearings prematurely. Don't use the ones made in China and don't overtighten the belt. It is really easy to overtighten and not realize it. If it slips it is too loose but don't tighten much more than that! For the technicaly correct procedure refer to N:08:13 step 6. If you install a new belt it should be a little tighter and rechecked in about a week as new belts strech a lot when first installed. The bearings can be obtained at any large power transmission parts supply. Bring the old ones and match them up. They are about $2.00 apiece for someone off the street, over the counter cash sales. In LARGE quantities they are probably less than a buck each for the GOOD ones. David Teitelbaum vin 10757 --- In dmcnews@xxxx, dherv10@xxxx wrote: > Walt and Group, There is different bearings.
