I have this little old Makita trim saw with a brake. Not a bad
saw ‘cept it was used to cut stone and has slurry all over it.
Finally I used a “Shark” steamer get the guard parts unfrozen,
but I blasted the lube out of the bearings too…

The dumb thing was buying this thing in the first place
and thinking the grime wouldn’t be a problem. Anyway,
is there a way to get the bearings running smoothly again
or do I have to replace them?

The bearings in most portables are sealed. If you ‘blew the lube’ out of it you likely compromised the seals as well. Any attempt to re lubricate them will be short term. The good news is that most bearings used in small tools are easily found at a bearing supply. The bad news is the old ones can be a bear to remove/replace.
Good luck.

Replace them. They should be readily available and not difficult to replace unless they are stuck on a shaft. Get a good puller and you shouldn’t have too much of a problem. Good Luck

The bearings should be sealed. I’d put some white lithium grease on it to see if that helps though just the same, if not, new bearings.

Do you want to cut your losses, Loren? You don’t sound exactly head over heels over this tool.

If it does have a place in your heart and in your shop, take it to the Dr. and have it fixed right and enjoy it!

I have a hunch you will have invested less than a new one. And older stuff is better, right?
