how to make a HF grinder last longer

[Bluethunder3320]

i got curious, so i opened up the gearbox, to find this.

so wipe out whatever grease is still left in there:

fill it with some GOOD grease! (anything should be better than the grease they used....)

loctite on the screws FTW!

reassembled

done

and now it should last MUCH longer, run smoother, quieter, and cooler!

(BTW i am not responsible for you breaking something on your grinder doing this) i did it and my grinder is running great, but do this at your own risk.

you have to run it for like a minute no load to let the gears spread out the grease.

of course you would use BLUE loctite, lol, but it does look better

better grease. even wheel bearing grease is better, its not much different from gear grease.

blue loctite is good because red loctite is permanent, you will NEVER get the screws out again.

should prob use high temp grease as used in lawnmower gear boxes and weedeaters etc.

iduno tho grease is grease use what ya got

This is the absolute truth! You would never break those little screw free. The heads would just get mangled and stripped.

^^^^

Already stripped one.

Cheap chinese hardware. Slotted it with my dremel so i was able to get it out.

Only way I'm aware of to remove red loctite on a small screw without destroying the screw is heating it up until the loctite melts.
