I didn't feel like going back endless pages of this thread to find the answer to my question so here goes? When do you guys know when to replace the bearings on these? I heard that if a grinder takes a long time to wind down, its because the grease is drying out and bearings need replacing. Any insight?
All things equal (HP, size of wheel/stone, wind direction, phase of the moon, ...) a new bearing will tend to have more 'drag' due to the grease.
What I check when buying a Block grinder is the end play/sloppiness of the arbor. I'm not sure why, I haven't bought 1 that has any.
Then I stand to the side and turn it on,
never in front of the grinder when starting. This is just a precaution, in case the vitrified material has been damaged and comes apart.
I've brought home a few Blocks, most here would say more than my share LOL. Some hardly used, others that were sad, sad looking Blocks.
They are all worth rescuing IMO. So, I almost always clean them up, tear them down, replace the consumables (bearings, stones, wire wheels ...) inspect/clean/repair electrical, and finally paint and re-assemble.
Oh, then I use them; or, give them to friends/relatives. I've sold a few also.
IMO, the bearings are not expensive or hard to replace. So, why not replace them?
Be sure to post up pictures as your restore progresses.
PS - Does anyone know why I'm suddenly getting double spacing, when I hit enter?
Like this?
