Picked up one of these too, thought the front bearing was gone , it had heaps of play but the bearing had actually slid forward on the arbor shaft and was no longer seated in the housing. I've searched a fair bit, but don't see any posts with real info on changing the bearings for these saws (presumably the latter star diamond, diamond pacific versions as well. So putting this here for the next finder.
Sort of an odd design, not the best imho. The housing does not have 'shoulders' to seat the bearings against. Rather there are three snap rings to position the bearings and flange on the shaft....
you can see that while the bearing on the drive side is flush with the housing, the one on the blade side is recessed a fair bit. I'm waiting on new bearings to reinstall, but think that the two snap rings are inside of the two bearings. Assembly then needs to have the flange also removed so that you can make sure the bearing on that side is fully seated, and hasn't slid up the shaft instead -( I think that's what happened to the saw I have.) Then press the saw flange on last after both bearings are fully seated.
I like the ease or removal for the auto feed, interesting looking little saw.

Thanks for posting this! I use these saws, and wondered how to go about fixing that.

This looks exactly like what my GemLap 10" setup looked like, but a different housing. Pretty interesting way of doing things.

Hi there! Thanks for posting about this. I just picked up the same/similar model - Beacon Star TS-10 - and absolutely love the dual trim/slab capabilities of it. But... I had a similar concern as you. The shaft moves horizontally and allows the blade to touch the side of the saw slot. I haven't fully disassembled it yet, but noticed the snap rings. I also didn't know the inner flange came off the shaft - haha. After you cleaned and added new bearings, did it still have the same play in the arbor? I wasn't sure if I should just use a spacer on the pulley side to ensure the shaft can't travel far enough to rub against the outer edge of the saw slot. My feeble ASCII diagram... ==|pulley| --spacer--|STAR ARBOR|==<saw>nut. Thanks for any insight you can provide... Have you been using yours as of late? -Matthew |

hmmm That saw quickly moved on to a new owner. Been a while and don't remember all the details.
I think the spacing is all dictated if the snaprings are in place and the bearings are well seated AND STAY THERE. there isn't anything to keep the bearings from working towards the end of the shaft besides the press fits. Think that I fit a 5/8 lock collar in front of the blade side bearing, probably good to do both ends or push the pulley snug to the bearing on the back? Good luck with it. |
