Default To grease or not?

Doing a tune up on a Granite gantry cutting saw. Am cleaning the tracks and gear racks from years of grease and granite dust. As I am cleaning the old dirty grease out, I am wondering if I really should put grease back on the gears. My thinking is telling me that when the granite dust lands on top of the gears, the grease will hold it and wear out the gears faster, or allow it yourself build up and create problems with filling up the track.

Would it be better to not not to grease the gears, and then hopefully the dust will be able to be blown out regularly. Of course, this is counting on regular maintenance being done, but since that is my part time job, I figure I should keep up on it.

After I get everything cleaned up, then I have to adjust the gantry to make sure it is moving and cutting Square, and the rotating table is level and locking properly.

I also think I should adjust the gear down a little bit too.

Any comments or suggestions.

There is a lot of water used in this shop, so I probably need to put something on the gears to keep them from rusting, but what would work that would keep granite dust from sticking to it?

If a light spray lubricant is adequate then you should get good results from Fluid Film. It is lanolin-based rather than being petroleum-based, does not attract dust and is highly resistant to corrosion.

As an example, I used to carry graphite to use on residential door locks because around this area the dust & sand in the wind will glop right onto any kind of wet lubricant (WD-40, et all). I had to be really careful with graphite because it's a mess to clean of it you get it in carpet or even vinyl flooring.
Once Fluid Film came along I tried it and it worked better and was less messy than powdered graphite. I had one outdoor padlock on my shop gate that locked up from the blowsand 4 or 5 years ago. One squirt freed it up & I'm still using it.

I'd bet that it's worth a shot.

That blow sand sucks! I've had to cut so many locks off my gates because of it...
Where can the fluid film be normal or commonly bought, Parts stores or hardware stores... I haven't seen any on shelves while looking for lubricants
Sounds like it will work well here especially my locks for the gates... eh and I'm sure I can find other uses for it too...

Remington makes a dry lube meant for carry pistols. It's teflon based, and sprays on wet and drys into a kind of a very light wax. You can usually find it at wal mart pretty cheap and I've had pretty good luck with it but have mainly used it on guns.

Brian I would contact the manufacturer and see what they recommend. The abrasive grease/dust mix does not sound correct.

Cat recommends a dry dry lube for road grader tables. It allows you to blow sand & grit off without removing the lube. Works for me.

One of the gears , either the rack or pinion should be soft (not hardened) and meant to be sacrificial.

Probably going to go with shades suggestions of marine grade. Have not finished all cleaning yet. Got side tracked on other saw again. After another 10 hours of adjusting and making test cuts, I have it with in .030” on the diagonal again.

Do you use any coolant (metalworking fluid) etc. in the water or just plain tap water?

Just tap water I believe. This is the granite beam saw I am talking about here . For some reason it started cutting out of square more than the tolerance I had it within 9 months ago.

This pic is the small saw I am working on. I can’t find a pic of the big one that I just worked on.
