Re: GW603 machine size setting
Hi
If you live in Auckland you can get 2x 6005 bearings + seal from a company Bearing Wholesale Ltd 95 Morrin Rd for about $15 (cash sale). The seal needs to be replaced once removed.
Try removing the shaft to check the bearings independently. If the bottom bearing is the only one gone it’s an easy job no seal to replace. Also check that the shaft is clean at the point where it makes contact with the seal, as grit can work its way into this area causing seal failure.
If you don’t live in Auckland try your local bearing supplier, as there’s a good chance they may sock the bearings and maybe the seal.
