Hi everyone,
I need some help/advice on my trim saw. Its started making knocking sounds. I assume it is a bearing problem...loose or needing replaced. I have two brand new bearings now, but I haven't been able to find any instruction on how to change them and am not familiar with maintenance and repair on the saw. It's a Lortone TS10-C. It came with a 2 page instruction and part list, but it doesn't cover my issue, and I cannot find anything on youtube or the web. Any help will be great, what tools? What type of grease? Thanks in advance

Welcome to the group from Southern Utah.
It could also be that the set screw for either the motor pulley or the blade pulley is loose.

Attached is a scan of the Saw Arbor Shaft Replacement and Blade Alignment Instructions for the Lortone LS10, LS12 and LSS-14P saws. The same procedure described is used to replace bearings and then realign the blade after replacing bearings. And is similar to the process of doing so on your saw. Hope this helps. Larry C.  |

My husband jumped into trying to fix the issue without knowing what to do, without instructions. I hope he didn't mess anything up, and we are now stuck right in the middle of trying to change the dang bearings. The outer bearing eventually came off ok, but the other one?? The one sitting next to the frame, ITS STUCK, it will not come off of the shaft! My saw now sits where it is, on the kitchen table, in pieces..for now. He said his friend has a press and will get around to having him fix it for me.

Use the fact that it is in pieces on the kitchen table to your advantage.
Tell him that you "will get around to" cooking again when you have a working saw and a cleared kitchen table.

Sometimes heating the bearing (a bit),helps to remove it.....

Too late for you but many times a knocking sound is a loose pulley. Bearings make funny noises too. Motors also so always remove belt and run motor to eliminate that. If bearings are bad you can turn shaft with belt off and feel roughness or find play if moved back/forth/in/out.

there is no roughness when it turn the bearings. I started the saw with no belt attached and it is quiet, sounds just fine there. I did however see there is a felt washer that was missing from the arbor shaft. I have looked at the lortone diagram, and am unable to determine where a felt washer would sit, from the looks of the drawing it would go on the outside of the stainless steel housing and between the outer wall and the inner bearing..which I really do not find feasible. So I am trying to put the saw back together, because I did manage to get a friend to come help get the stuck bearing off the arbor shaft..but there are now heavy grooves in the arbor shaft. The shaft goes on fine through the first bearing and through the belt pulley, but gets jammed going into the other bearing! I am getting super frustrated here guys! I just want to cut rocks and cannot seem to catch a single break getting this things back in order.

Lift the guard up over the blade and run the saw.
Did you tighten both set screws on both of the pulleys?
Do the pulleys look like they are in line with each other?
Does the blade run true or is it wobbly?

If metal is stuck to metal, I use LIQUID WRENCH.
Has worked for me. Not an expert. No way!!

Get a hard Arkansas sharpening stone and rub it in a circular motion along the shaft where the gouge is.
The felt washer goes onto the shaft before the machined flange that the blade buts against.
